Since its release, the inov-8 Terraultra G270 has received acclaim all over the world. Many magazines, reviewers and bloggers hailing it the shoe of 2020. In late July I wrote my review HERE.
Now, with over 600km+ in the shoes it’s time to make a long-term review and assessment.
I am not going into the analysis of the shoe as in a typical post, you have a review linked above that goes through the pros and cons and all the technical jargon. This is a usage review.
First off, the Graphene outsole and 4mm lugs is a 100% winner. The durability has been superb, the grip incredible and the traction has been without equal. Even in mud, the outsole has performed but of course it is compromised. The lugs are just not aggressive enough to grip in very soft or deep mud, but a thin layer of mud and the G270 really does perform. Wet rock grip has been superb and arguably the most impressive aspect. Many have raved and provided a 5/5 review. I can’t give 5/5 because it is compromised in mud, therefore it gets a 4/5 BUT and this is a BIG but, in all honesty, you should not be using the G270 in mud, there are other shoes for that. So, if reviewing for intended purpose, it would get a 5/5. This may sound a little weird, but the G270 has become my ‘go-to’ road shoe, especially with the arrival of Autumn and Winter, the grip on wet roads, pavement and hard-pack trail has been superb. Although not a ‘hybrid’ shoe (road to trail) it performs like one and I would recommend for that use.
The cushioning has really surprised me. It’s plush without being squidgy. It’s super comfortable without losing that all important feel for the ground. It takes 20km hard trail runs in its stride and still allows legs to feel fresh after. The G270 is designed for longer races and as such, it comes highly recommended. An improvement on the G260. There was a mention of a ‘Boomerang Insole’ in the technical jargon that provides extra energy return, I have no idea if this is resulting in the positive feel of the shoe, but something is definitely working better over the previous G260 incarnation.
Zero drop – you are either going to be for or against. I am fortunate, I test shoes all the time and I am regularly mixing up drops from 0 to 10 and all the steps between. With zero I am usually careful not running too long or too often. The G270 changed that, I have been running regularly 3-4 runs per week since November with total distances of 50-80km (per week) just in the G270 and they have been superb. The days between I have been using 4, 8 and even 10mm drop on the odd occasion. Drop is very personal, so, I just warn against potential problems if zero is not normal for you.
The toe box is wide, and I have really enjoyed the extra space and comfort on long road or hard trail runs. With Injini socks, my toes can really splay for comfort. The G270 would be a great fastpacking shoe or multi-day shoe. I can see it being really popular in races like Marathon des Sables. The wide toe box though is too wide for me on technical trail… I don’t have the control or the precision I need, so, it’s not a shoe for me when running on technical terrain.
A major improvement is the upper. After 600km+ I have no signs of wear. The important ‘bend’ area behind the metatarsals that can often split in the corners is still good and showing no weakness. I mentioned the hold of the foot in my initial review and that has been one of the key pluses of the G270, particularly over the G260. The lacing, ‘Adapterfit’ and hold of the instep is reassuring, particularly important for me with a wider toe box.
All things considered, the G270 is one of the shoe highlights of 2020 without a doubt. It’s not perfect, but then again, show me a shoe that is. If you want zero drop, grip, traction, cushioning and a wider toe box, I think you’d find it hard to find a shoe that compares with the G270.

It shouldn’t be complicated, but it is. Go on any run forum and I will bet you that daily, someone will ask a question about run shoes.
I want a shoe that will allow me to run muddy trails and road?
Can anyone recommend a shoe for fell running?
I have Hobbit feet and I need cushioning and grip – what shoe?
I could go on and on. The thing is, while it may be okay to ask a couple of question like:
How does a specific shoe perform in mud?
How is the wear and tear of ‘x’ shoe?
Asking for a specific shoe recommendation can be a recipe for a disaster, the reason being, we are all individual and shoes are very personal based on a multitude of factors. Nobody on social media knows you, your needs, how you run and what type of running you do.
So, please do not ask for a shoe recommendation on social media unless you are specific. A good example being:
“I am male, aged 44. I have been running for 23-years and I have extensive history in cycling, triathlon, road running and now I am moving to trail running… I am 5ft 9. A little overweight. In regard to shoes? I am looking for a trail shoe that will provide great grip on muddy trails. I need support for my arch and cushioning but not something as cushioned as say a Hoka. In regard to foot width, I am in the middle, neither needing precision or wide fit. On a scale of 1-5 I would be a 3!’
With the above we have information from the runner and therefore suggestions and recommendations can be specific and targeted. Even then, the runner should go to a run store, albeit now he has a shortlist of options and then try on the shoes to find the one that best suits him, his feet and his needs.
IF THE SHOE FITS
Firstly, and importantly, not all shoes are equal and not all feet are the same.
Quite simply, the better a shoe fits, the more specific to the type of running one will do in that shoe, the more likely you will feel better. The foot will be happier and the miles you run will be more comfortable.
Our bodies are supported by our feet; they are the first point of contact with the ground and therefore, they are incredibly important. Getting a correct fitting shoe that is specific for purpose is crucial.
When I say specific for purpose, let me provide some simple clarification now and then explain in-depth later. Shoes come in categories; I see the main list broken down as 6 main groups:
Road to Trail
Ultra-Running (with sub heading of Ultra Road and Ultra Trail)
Now, one could break down the categories even more with very, very specific needs such as, “I need a mountain running shoe with an aggressive outsole with great grip in wet and dry conditions and superb traction in mud.”
But before we get into the discussion on the shoe for the job, getting a correct fitting shoe is vital.
HOW DO WE FIND A CORRECT FITTING SHOE?
Please don’t fall in with the generic advice that a run shoe should be one size bigger than say your every day casual shoe! For a start, this assumes you have the correct size casual shoe and trust me, from experience, very few people do. The recommendation for sizing up also comes from the assumption that a foot swells when running. From experience, feet rarely go longer but can go wider with repeated impact and stress; think of races like Marathon des Sables when a runner is in a hot/sandy environment. So, one may need a wider shoe but not a longer shoe. This comes down to getting the specific shoe for the job.
I wear the same size run shoe as my casual shoes (typically) but to clarify, I go for the ‘same fitting’ shoe.
Shoe sizing between brands is variable and inconsistent, an EU 44 in say Salomon is not necessarily the same as an EU 44 in inov-8. So, first and foremost, always try shoes on!
Length and foot width does change so it can be a good idea to have your feet measured if you are new to running with little experience. Some specialists suggest getting feet measured yearly, but for me, this still only gives a guideline to shoe size as comfort, feel and specificity come in to play.
“As a rule of thumb,” I have consistently found that a thumb nail of space above one’s big toe is usually ideal for sizing. This is classic for an ‘Egyptian’ foot shape (D). I say usually because I have seen some feet where the second toe is longer than the big toe, known as ‘Greek’ foot shape (C), so, this would require an individual approach. There is also ‘Square’ foot shape and the thumb nail width above the big toe usually applies here, but, a wider toe box may be required.
Remember, both feet are usually not the same size, so, take this in consideration. Go for fit and feel with the bigger foot!
NOTE: Specifics come in to play such as foot width and specificity of the shoe. As an example, If you are running technical trail, you will need a more ‘precision’ fit. If running long/road ultras, you may well prefer a wider fit that will allow toe splay. More on this later.
Wear socks that you typically run in and if you normally wear two pairs of socks, then wear two pairs when testing and trying. Two pairs of socks may require you to go a half or full size larger depending on the sock thickness. Note:nYou may wear the same shoes for Summer and Winter, but in Summer you use light and thin socks but for Winter you use thick Merino socks. This may well mean you need a different size shoe for Summer in comparison to Winter.
Insoles can give a good indication of the shoe size and its width. As a guide, the insole should match the shape and size of your foot.
With the insole back in the shoe, place your foot inside and firstly check for the space at the front. If you have the required space, lace up and tighten. On the top of the foot you have the ‘Navicular Bone’ and the shoes should be tight here but not so tight to restrict blood flow.
Stand up and move around. Key checkpoints are: 1. Thumbnail width between longest toe and edge of shoe. 2. Check pressure on your little toe. 3. Check pressure and feel on your big toe.
Ideally, you want to be able to run in them and most good run shops have a treadmill to try out shoes. Key checkpoints: 1. No slippage in the heel area. 2. No pressure on toes. 3. Instep feels secure and pain free. 4. You have support or a lack of support as needed.
If you see material bulging because of tightness you may need a bigger shoe, or you have the wrong width. If you see an excess of fabric, you may have a shoe that is too large or too wide.
Check the fabric of the shoe and the seams. Will they be breathable for your needs? Will they protect you for your needs? Does the toe bumper have enough protection?
Remember shoes flex when you run. In the propulsive phase, the shoe will bend behind the metatarsals and this can be a troublesome area if the shoes are the wrong size. Often a sign of a shoe that fits incorrectly is this area will crease and often tear causing failure in the shoe upper. If running uphill, think mountain, fell and trail running, this area of a shoe gets a great deal of stress.
A good running store with professional staff will help you with shoe choices and they should discuss the pros and cons of the specific brands and models available. However, gut feeling and how you feel goes a long way. Always be careful of ‘sale’ shoes! Don’t be influenced in buying the wrong shoe just because it is a good price.
WHAT CAN GO WRONG?
Marathon des Sables has some foot horror stories and the general story is because of the heat, the sand and how brutal the race is. The truth is, the issues (usually) arise through runner’s choosing the wrong shoe and the wrong size.
Old advice has said size up, go bigger as your feet will swell.
However, a shoe that is too big allows the foot to move inside the shoe. A moving foot causes friction. Friction causes blisters. The rest is self-explanatory. In addition, with each sliding of the foot, the toes may impact with the front of the shoe and result in bruising. Think of running downhill with shoes that are too big, your toes will be crammed at the front with room behind the heel.
Having said this, feet can swell through impact and heat. So, using Marathon des Sables as an example, one consideration may be going for a shoe with a wider toe box but still that thumbnail of space at the front. What often happens is a runner has a favourite shoe and decides they need more room, so, they just buy a larger shoe (than needed) because it increases the width/ space. Actually, what they should do is change the shoe. It goes back to specificity.
Shoe that are too tight and/or too small will result in black toenails but more importantly can damage ligaments and possibly result in damage to the metatarsals. Stress fractures are a real risk. Also, you will have foot fatigue and pain. The foot is full of nerves and bones. As an example, the soles are extremely sensitive to touch due to a high concentration of nerve endings, with as many as 200,000 per sole. *The foot receives its nerve supply from the superficial peroneal (fibular) nerve, deep fibular nerve, tibial nerve (and its branches), sural nerve, and saphenous nerve. These nerves come from peripheral nerves that arise from the L4 to S3 nerve roots and contribute to the somatic motor function, general sensory information, and the cutaneous sensation of the foot. In regard to bones, each foot is made up of 26 bones, 30 joints and more than 100 muscles, tendons and ligaments, all of which work together to provide support, balance and mobility.
If you require stability shoes, the wrong size shoe may well put the support in the wrong place and instead of providing help, it will create onward issues and problems. Plantar Fasciitis is a risk.
Quite simply GET THE CORRECT FITTING SHOE!
IMPORTANT FACTORS TO CONSIDER
Okay, so we have given a guide to how you find the correct size of shoe. But now we need to be specific and address and look at some fundamental questions before going to any run store:
Supinate – Your weight tends to be more on the outside of your foot.
Pronate – Your weight tends to be more on the inside of your foot.
Neutral – Your weight is distributed evenly.
You need to know which of the above you are, as all brands and manufacturers produce shoes to answer these three specific needs. If you do not know the answer to this question, look at the soles of shoes you have worn for some time – you will see how they have worn. In a proper stride, your foot should roll forward and pronation should be neutral. Shoes that are geared towards supination or pronation are designed to bring you back to neutral.
Many runners who need specific support often see a Podiatrist and have Orthotics made that are transferable to any shoe. In this scenario, you should purchase neutral shoes.
**If you supinate, it can cause excess strain on your ankles. It may lead to shin splints, calluses, or bunions on the outer side of your foot, and pain in your heels and balls of your feet. Excess over pronation, means that as you walk, your foot rolls toward the inside and your arch tends to flatten out. Your shoe will show uneven wear on the inside part of the sole.
From barefoot running to bouncy marshmallow shoes, there is a plethora of cushioning options available to choose from and what is best may just come down to personal taste…
However, I beg to differ. I feel cushioning or a lack of cushioning should be applied based on what type of running one is doing and what conditions.
Fell running – Fell running often takes place in soft, boggy and wet ground. A feel for the ground is essential so that you can respond with ever-changing terrain. A shoe with too much cushioning will remove that feel, place you higher off the ground and may well increase the risk of injury. A sprained ankle being one of the most obvious.
Road running – Road is hard, it can jar the body, muscles and tendons and therefore a shoe with a little more cushioning may be preferable. For some, they require sofa like comfort. Others prefer some cushioning but not at the expense for the feel for the ground.
When purchasing shoes, look at the cushioning typically shown as, for example – Midsole Stack 8mm/ 14mm. This is 8mm cushioning at the front and 14mm at the rear. The higher the numbers, the greater the cushioning.
Some shoes include a rock plate which offers protection from sharp objects, useful when trail running.
Shoe drop is essentially the difference between the height/ thickness of the midsole under the heel compared to the same measure under the ball of the foot. Years ago, drop was not a consideration. On a personal note, thinking back say 8-years, I never considered shoe drop. Now, it’s all important.
Importantly, do not be confused by cushioning here. You may well look at say a Hoka One One and think it has a high drop. On the contrary, they typically have a low drop of 4mm. ***Drop refers only to the difference in thickness between the front and back of the shoe and is not a narrative on the magnitude of the thickness.
From experience, I do not consider that any runner has an ideal drop. I see drop as something that can played around with based on the needs and requirements of the shoe and the conditions it will be used. But I must clarify that I have been testing shoes for 8+ years and switching drop on a daily basis has been no problem, on the contrary, I actually consider it to be beneficial.
As a way to explain, I use 0 drop shoes all the way through to typically 8mm. I do have one pair of shoes at 10mm, but they are an exception.
Zero drop or barefoot advocates will argue and argue that zero is the only way to go and if you are adapted and have no injury issues, that is awesome. However, most people have not experienced zero drop and suddenly to do all runs in zero will almost certainly result in some injury. Zero takes adaptation.
Pure Sports Medicine are clear, “What we do know is that human tissues can be sensitive to sudden changes in the way they are loaded, and that it is biologically coherent (and in keeping with the laws of physics) that differing shoe drops may load certain tissues differently. As such, if you are currently uninjured there is no justification for changing the drop of your shoe, but should you want to then be mindful of allowing the body time to adapt to such changes (although many runners may be able to interchange between shoes of different drops we would usually advise being over cautious if this is not something you have done before).
So, if you typically run in 8mm drop shoes without injury, it makes sense you purchase shoes with 8mm drop. Equally, if 4mm is your thing, purchase 4mm.
Specificity of drop.
I personally (and others like me) see drop in conjunction with cushioning, or, a lack of cushioning as a tool to get the most from my body and my runs. For example, if running a muddy fell run, I will use a lower drop, say 3 or 4mm with less cushioning. By contrast, if I was doing a long trail run, I would prefer 8mm drop and more cushioning.
A certain drop may be beneficial in reducing sensitivity and complementing your overall management strategy – so consider this. ****Changing the drop of your shoes (or using multiple shoes which have varying drops in a rotation system) is not to be discouraged or feared, but be sure your body’s tissues can tolerate this, and are given the necessary time to adapt and attain the capacity if needed.
The outsole of a shoe is key as this is the point of contact with the ground on which you are running. Again, specificity is key. There is no one outsole that will do all jobs well and therefore the need for multiple shoes with specific tasks is an essential armory to a runner’s shoe cupboard.
Road shoes – Typically need little grip, just a good rubber.
Trail shoes – Typically require a good outsole that is durable and has grip, say 4mm studs.
Fell shoes – Typically will be aggressive and on first looks may look like football boots with 6 or 8mm studs.
Mountain shoes – Typically will be a mixture of trail and fell shoes and the outsole will be sticky to provide good grip in wet and dry conditions.
In an ideal world, if you ran all of the above scenarios, you’d have a pair of shoes for each scenario. However, shoes are expensive and many runner’s need to make some compromises. Brands realised this and for example, some offer road to trail shoes that provide a best of both worlds’ scenario. The inov-8 Parkclaw is a great example. “the perfect shoe for runners wanting to run on paths and trails, or those looking to make a transition from road running to trail running.” – inov-8
If you need grip for mud, you need to be specific, there is no compromise.
Like drop, shoe width can create many an argument. Simply put, if you have a slimmer/ slender foot, you can probably wear any width shoe providing you have the correct size and they hold you securely.
But if you are a Hobbit, shoe choice may well be compromised as you will need to look for a wider fitting shoe.
Shoe width is also a consideration based on other factors: 1. What terrain are your running on? 2. How long will you be running?
On a personal note, if I am running on technical and challenging terrain, I want a shoe that fits and holds my foot. I am not worried about toe splay – precision is a priority. By contrast, if I was running on groomed trail for multiple hours, a shoe with more width may will be preferable to allow my toes to splay and relax.
Like drop and cushioning, I mix the width of my shoes based on my needs.
Some companies, inov-8 for example provide a width guide to steer runner’s to shoes that will specifically answer their personal needs. This a great system that takes some guess work away. The system is simply rated 1-5; 1 being a tight/ precision fit, 5 being wide and spacious.
Brands such as Altra only offer one foot shape and believe that a wide toe box is essential, in conjunction with 0 drop. It is a toe shape foot box that allows toes to relax and splay. The big toe has space and in principal, this foot box helps reduce overpronation and increases stability. On a personal note, Altra has a place for long road, ultra or trail runs, but when the terrain gets challenging, they feel way to sloppy for me – but this is a personal thought. Altra fans or wide toe box fans will disagree.
WEIGHT AND FABRICS
Shoe weight can be an important consideration. Certainly, when racing, a runner may well prefer a lighter shoe so that they feel faster. However, if running an ultra, added cushioning and a little more weight will be worthwhile for comfort.
Shoe fabrics, seamless uppers, sock-like fits, Gore-Tex and other considerations may influence a shoe choice. Make a decision based on specificity.
A lighter shoe will typically not last as long – this may be an important consideration too.
CONCLUSIONS AND SUMMARY
Is choosing a run shoe really THIS complicated?
I suppose, yes! But once you understand the basics purchasing new shoes should not be too complicated. Below is a summary and process to follow:
Measure your foot.
Use a conversion chart to get your shoe size.
Understand gait and what you need. If using orthotics, you need neural shoes.
Ask yourself what terrain the shoes will be used on – This refers to what outsole.
Ask yourself how long typically you will run in these shoes – This refers to cushioning.
Do you need the shoes to be more precision fit or wider?
Look at brands/ options and based on the above make a shortlist.
Try the shoes on using the size provided from points 1 and 2 but then size up or down based on the thumb nail space rule.
Check the heel for slipping.
Check the instep and confirm a good foot hold.
If possible, try the shoes running.
Reduce the choices down to 3, then 2 shoes and then make an informed and educated decision.
Do not be influenced by the colour or the price.
Lacing can make a huge difference to how a shoe holds the foot. Lock lacing for example is very popular for off-road and challenging terrain as the shoe holds the foot more securely.
Compromise is a killer when it comes to run shoes. The more specific you can be, the better the shoe will be. But, if you have correct fitting shoes with appropriate cushioning, correct width and a good outsole, you will be able to head out the door and enjoy the process.
And yes, there are exceptions to the rule and somebody will use shoes that are too big and get away with it. Just as someone will run in sandals and get away with it. These are exceptions to the rule and not the norm.

The development and progress of the adidas brand in the trail running world has for many years been spearheaded by Luis Alberto Hernando, and what an ambassador he is!
Now, ‘TERREX’ is changing at an alarming rate and in the past 12 to 18-months there has been significant growth and development in shoes, apparel and athletes. Without doubt, adidas are now pushing hard in the trail and mountain world.
The TERREX AGRAVIC FLOW is a shoe that encompasses the road history of the brand and welcomes the development of the trail brand. The shoe clearly transitions from road to trail and back again all packaged in a really good-looking shoe.
My pair are solar red/ core black and grey two. There is no hiding in these shoes, they are colorful!
For clarity, Adidas use three descriptive names for their shoes: SPEED, AGRAVIC and TWO.
SPEED offers a narrower fit and is arguably a more performance orientated shoe.
AGRAVIC offers a standard fit and is arguably more of an ‘everyday’ shoe.
TWO offers a wider fit and more cushioning for longer trail days.
The TERREX AGRAVIC FLOW falls into the everyday category and adidas confirm, ‘Pavement to trail and back, your feet stay cool and the transitions are seamless with a smooth roll-off and fresh energy in every stride. Foot-hugging support and sure-footed grip let you move across rocky, rooted terrain, wet or dry.’ I often do not like the way a brand tries to sell a shoe in a sentence or two, but I have to say, adidas sum up the Agravic Flow well in this description.
Billed as a regular fit shoe, I have to say, to me, it feels a little wider in the toe box than many other regular fit shoes. So, keep that in mind when looking at them and trying them on. I also personally feel that they size a little larger. I always use a UK9.5 but have found a Uk9 to be far more preferable with the Agravic Flow.
With 15mm cushioning at the front and 22mm at the rear, the shoe is a cushioned ride without compromising feel for the ground and the 7mm drop fits perfectly for an everyday shoe ensuring that a day on the trail will be relaxed and comfortable.
The outsole is by Continental and the German brand really do know how to make a grippy outsole. With 3mm lugs, the Agravic Flow is never going to cut it when the trail gets sloppy and/ or muddy. However, on hard pack trail the grip is superb. On rock, wet or dry, grip also excellent and importantly it gives a real feeling of confidence which allows you to run without hindrance. The transition to road is seamless and comfortable, no doubt contributed too with the BOOST cushioning.
Cushioning comes from BOOST technology and you really feel the comfort as soon as you put the shoes on. There is also EVA in the frame to reduce weight and this in turn, provides some stability. If you have not used a BOOST shoe before, give them a go, the energy return and comfort levels are excellent.
The upper is one the stars of the Agravic Flow, it is mesh with abrasion resistant welding. It is seamless and uses a sock-like construction. If you have read my shoe reviews before, you will know I love sock-like construction and the same applies here for the Agravic Flow. You slide your foot in and immediately it feels snug. You could, if you should wish too, use the shoe without socks?
The laces sit on top of the upper and are sewn in offering 5 eyelets on either side, the middle eyelet set back allowing on option to loosen or add more tightness to the upper when fastening. There is no option lock-lace as there is only one eyelet.
The toe box, as mentioned previously, feels wider than standard and at the front there is an overlay to add a little protection and the outsole curls up to add some reinforcement. But toe protection is minimal. At the rear of the shoe, the heel box is plush and comfortable, and it held my foot well both when going up and down trails.
There is no tongue as the shoe is a sock-like, so, comfort levels are high. You see the number ‘310’ this refers to the weight in grams of a UK8.5 shoe.
Built on a neutral last, the EVA on the medial side wraps up to offer some arch support. It’s subtle, but noticeable. I wouldn’t call the Agravic Flow a support/ pronation control shoe. Equally, I could not call it neutral. It sits somewhere between but being a runner who uses neutral shoes, I find the Agravic Flow very comfortable.
The Agravic Flow is a great everyday shoe when the trails are hard packed, and you want comfort, support and reassurance. They are not for muddy days! The transition from road to trail is superb and seamless, you can feel adidas’ road heritage in the shoe.
The BOOST technology is really noticeable and gives a real bounce, especially on rock, gravel, tree roots and so on. This is not at the compromise for feel for the ground though. So, when the trail becomes more technical, I was never worried about foot placement and confidence. The toe box is wider though, so, when running on very technical trail, I would prefer a firmer hold at the front. You can’t have it all and the Agravic Flow does a great job of allowing toe splay. So, it’s a great shoe for longer trail days when comfort is needed. The outsole is excellent in the wet and dry on non-muddy trail.
The sock-like upper is just plush and comfortable. There is nothing to criticize here, I wish all shoes could be this comfortable. Quite simply, you could remove the laces and they would make a great pair of slippers – yes, they are that comfy.
The laces work well, it would be nice to have that extra eyelet to allow lock-lacing, but that is a minor niggle. For me, the shoe does have a wider feel than standard, and I therefore found that I could compensate by adjusting the laces to hold my foot securely.
I do feel that the shoe sizes larger by a half size, so, if purchasing online, keep that in mind. Ultimately, you need to try the shoe on.
The Agravic Flow is a great shoe that manages to mix road running and trail running seamlessly. It’s a shoe that you can pretty much put on every day and enjoy its ability to feel like a road shoe and then when on the trail, enjoy the cushioning and grip of the best out and-out-trail shoes. There is little not to like in this package from adidas.
If you are looking for one shoe that covers many options, the Agravic Flow is a great place to start. If you want a road shoe, look elsewhere. If you want a trail shoe with comfort and grip for dry/ wet trails, then this shoe ticks the boxes.

We all run long, but the length of a long run can really vary depending on many factors such as age, fitness, race and training history, targets, objectives and available time. I get asked and read, time and time again, the question, ‘How long should I run?’
‘What session you doing?’
‘Long run today,’ the answer.
But, what is a long run and how long should a long run be?
Before that question can be answered, one needs to understand why one is running long and for what purpose. Typically this will be a long-term event that is planned in the diary that may or may not be a race.
Having a date to work too is a great starting place as it provides a deadline point. This helps focus the mind and plan the time accordingly.
Ask yourself, what your objectives are? For example, there is a difference between competing and completing?
What distance is the event? (What is the time limit, what are intermediate cut-off times?)
If you are used to running 5k and 10k events, a long run for you may well be 75-90 minutes? If you are a marathon runner, your long run may be 3 to 3.5-hours. If you are running an ultra, this is where it gets tricky.
Why do we run long?
In summary, we put an emphasis on 3 key points:
Muscular and physical adaptation
Efficiency to use fat as a fuel
If you have never run for more than 1 hour in training, then 3 hours on your feet just feels like a really long time, so, you need to adapt mentally for the challenge ahead and you need to be strong to get the job done. This time on feet, needs to be appropriate to the challenge one has planned.
Muscular and Physical Adaptation:
Muscle soreness will come for everyone, however, we can train to reduce the impact or delay the process by progressively running longer in training. With recovery periods, we allow our muscles to adapt to the stress and they become stronger. Delayed onset of muscle soreness (DOMS) is not pleasant and it something that can really be painful in the 24/ 48 and 72 hour period after hard/ ;long training or racing. By running long in training we adapt to delay or reduce the DOMS.
Efficiency to use fat as a fuel:
Our bodies can only store so much carbohydrate and once those stores are used up we have only two options left: top them up or slow down and maybe even stop if they have got very low. As an endurance athlete we need to tap into our almost unlimited fat stores. We do this by teaching our body to use fat as a fuel during the long run. The more efficient you become at this, the longer you can run and the longer you can maintain a pace. Ultimately it means the whole race/training experience will be better and more enjoyable.
The Long Run
Running longer requires running slower, especially if we are going to switch fat burning on. It requires a pace that one can maintain for hours and hours and yes, that pace can be walking. The long run/ walk is specific to you and nobody else!
Running hard and faster has its place and yes, top elite runner can and will incorporate faster paces within a long run to adapt. But be specific and think of your objectives and what you are trying to achieve.
Be specific with terrain. No point for training for a 50-mile trail race with loads of vertical and technical trail and then run all sessions on the road.
Runners get stressed and worried by mileage, pace, miles per minute and so on. Relax. Think of your long run in terms of time, not distance. Particularly important if running off-road.
To help provide perspective, 3-hours on the road you may well allow one to cover 20-miles, but on the trails or in the mountains, one may only cover 12-miles.
A common mistake is that we make our long run too fast and our faster runs not fast enough. We therefore end up one paced. Make longer sessions slow and make hard sessions hard. If in doubt, use RPE, Rate of Perceived Exertion. Quite simply, when running long and easy you should have a perceived effort of breathing calmly and being able to talk. If running hard, you should have a perceived effort of difficulty, shortness of breath, discomfort and an inability to hold a conversation.
The big question, how long should the long run be?
Short distance runners often run ‘over distance’ in training. For example, a 10k runner may run a long slow half marathon to build endurance. A half marathon runner may run a long and slow steady 16-20 miles in preparation for a fast race.
This all falls apart when we go to the marathon and beyond. How often have you heard in marathon training that the long run should be 21/22 miles or 3-hours 30-minutes in preparation for a race. But these generic terms do not take in to account the individual. Think of Kipchoge, if he did long runs at 3.5 hours, even running slow (7 min miles for him,) he would cover over 30-miles!
Long runs and adapting for an endurance run such as an ultra comes from not one run but a combination of all runs. It’s about your accumulative run history. They all add up to make you an endurance machine. So, typically, if you are running longer than a marathon, you will have been running for some time.
First and foremost, consistency is key and long runs should be progressive and based on ability and experience. A long run should test you but not break you.
What do I mean by progressive?
Let’s use a 12-week scenario based on a runner who can currently run 2-hours in a long run. I am not looking at base training here, but the specifics of a long run and how to make the long run longer. I’m a big fan of building over 3-weeks and recovering for 1-week.
Week 1 – Sunday 2:30 hours
Week 2 – Sunday 2:45 hours
Week 3 – Sunday 3:00 hours
Week 4 – 2 hours
Week 1 – Sunday 2:45 hours
Week 2 – Wednesday 90min / Sunday 3:00 hours
Week 3 – Wednesday 90min/ Sunday 3:20 hours
Week 4 – Sunday 2:30 hours
Week 1 – Wednesday 90min/ Sunday 3:00 hours
Week 2 – Wednesday 1:45 hours/ Sunday 3:30 hours
Week 3 – Wednesday 2:00 hours/ Sunday 4:00 hours
Week 4 – Wednesday 60min/ Sunday 3:00 hours
The above scenario provides a structured example on how to build up from running 2 hours comfortably to 4 hours. But remember the above scenario is 12-weeks of running with over 37-hours of running, just in the long runs!. That is huge and a great place to start for any endurance challenge.
But my race is 50-miles, can I run the distance?
As mentioned above, it’s not wise or sensible to run too long in anyone session. But the 12-week plan above on a 3/1 scenario shows you how it’s possible to build time and confidence. As you gain more experience you can look at doing back-to-back sessions and plan long training weekends all as part of a long term plan (see below.) Ultimately though, running too long in terms of distance or time is something that should be very carefully planned. You will always here about runners who can do 200-mile weeks or 50-mile training runs; they are exceptions and not the norm. Don’t be lulled into a false sense of security and don’t feel inadequate, we are all individuals and this is maybe the most important aspect.
Running or walking long is a voyage of discovery and you need to balance long-distance with adequate recovery.
Listen to your body.
Training should be about preparing you to tackle the challenge, but it will never FULLY prepare you. There’s always going to be a bit of extra and a bit of unknown on the day of the event, but surely that’s why you’ve entered?
I have to be honest, I wasn’t particularly looking forward to using inov-8’s new shoe offering, the PARKCLAW 275 (I tested the GTX – Gore Tex). Why? Well, inov-8 have always impressed by producing shoes that are specific to a runner’s need – typically, getting a grip in muddy trail. Over recent years though, many new inov-8 shoes have appeared that have merged that ‘specificity’ and in all honesty, I have always been impressed by what has been on offer.
The PARKCLAW though just didn’t entice me.
I have to say, I was a little silly. It turns out that the PARKCALAW 275 is a great shoe and in all honesty, it’s a shoe that will appeal to so many.
Many runners want a shoe that does more than just one thing. The PARKCLAW is going to be that shoe. Good on the road, good on dry trails, good on rocks, cushioned, wide toe box, 8mm drop and great feel.
Inov-8 have produced a real surprise!
Maybe the ‘PARK’ in the name signifies the ever-growing parkrun community that every weekend assemble all over the world and bang out a 5k amongst friends. Let’s face facts, it’s a huge community and if you can get a slice of that pie, it’s a great thing for any brand. But many of those runners may want to mix things up with a little road-to-trail or easy trail runs. This is where the PARKCLAW can step in!
I need to clarify here that the PARKCLAW is a shoe that works for any runner. I have been using it on my road loops of 5, 8 and 12km and they have been great. Equally, they have been excellent on my local canal tow path and forest trails.
The shoe has an ‘in-between’ outsole that provides grip for trail but not too much grip for road. The lugs at 4mm are semi-aggressive but importantly are close together so road running feels good. META-FLEX at the front allows the shoes to bend near the metatarsals and at the rear is a Dynamic Fascia Band. Three different lug colours are present which show how the different compounds ensure grip on different surfaces.
Drop is 8mm which is now pretty much standard, gone are the days of 12mm drop and higher. 8mm drop is a perfect starting point for most runners and particularly nice if running longer.
Fit is neutral and true to size. I always use a UK9.5 and these are perfect.
Toe box is wide – 5 on inov-8’s fit scale (here) so all you Hobbits should have a huge smile.
Cushioning is 12mm at the front and 20mm at the rear which provides a plush feel and not at the compromise of losing a feel for the ground. The Cushioned ride comes from Powerflow+ which does a great job at protecting but not at the loss of energy return. Combined with META-FLEX the Powerflow+ makes the propulsive phase a pleasure.
The upper is classic inov-8, breathable and lightweight. It has support on either side of the lacing section which pulls in to hold the foot firm once laces are adjusted accordingly. Importantly there are double eyelets at the top, so you can lock-lace should you wish. The heel area is plush as always with inov-8 and there is additional support to hold the foot firm and help with gait. The tongue is padded and gusseted. Toe box is reinforced and protected.
This is a very comfy shoe. Slipper like in feel and it was easy to pull them on and run with no bedding in. I was amazed at how comfortable they are. The Cushioning is unlike any other inov-8 shoe I have used. Maybe similar to a TRAIL TALON.
The key thing for many will be the wide toe box. Hobbits you will love them! I am fortunate that I can use precision shoes and then enjoy and benefit of a wide toe box when I want to be more relaxed and allow my foot to splay. The PARKCLAW is really comfy.
Gusseted tongue is padded and a real winner. Keep saying it, all shoes should have a gusseted tongue just makes sense!
The lacing is standard and it’s possible to adjust and get a great fit and feel. I used the additional eyelet at the top to ‘lock-lace’ but found I didn’t need it, the shoe fitted so well.
Running on the road is a real pleasure with excellent comfort, great feel and great energy return. At no point did I feel I was in a trail shoe. Transition to hard trail was seamless. The PARCLAW is a great all-rounder and one-stop shop for those who need something that can do a little of everything.
The 4mm lugs handled grass, rock and trail both in wet and dry but when the trails became muddy, grip was compromised. The lugs are too close together and not long enough to get the required purchase. This is not a criticism, it’s just a fact! Quite simply, if you are needing a shoe with greater off-road grip, you need another model of inov-8. The PARKCLAW is not intended for this job!
The PARKCLAW 275 is a real surprise. It’s a shoe that you can use day in and day out when you are mixing terrain. A great example would be say living in London and going for a long run when you mix road with sections of trail in Regents Park, Hyde Park and so on. The shoe though equally sits as a road shoe or dry trail shoe. I had no issue using the PARKCLAW 275 for either purpose.
The toe box is wide, and this may well be a real deciding factor for many. I know so many runners who need or prefer a wide fit – look no further.
The PARKCLAW would actually make a great shoe for a race like Marathon des Sables when an out-and-out trail shoe is not required but when cushioning and wide toe box is welcome. It is definitely a contender.
The PARKCLAW 275 will never be great on muddy technical terrain. The outsole is not aggressive enough and the wide ‘5’ fit would make the shoe feel sloppy and lacking precision.
Ultimately, I think inov-8 created this shoe as an ‘introduction’ shoe. A way of enticing roadies to trail. In doing so, they have created a stand-alone shoe which I have been using daily, and yes, it’s equally great as a walking shoe.
A jack of all trades is never brilliant at any one thing but the PARKCLAW 275 does a great job at making the mix and transition.
Finally, I tested the GTX version, so, should you wish, you can also keep your feet warm and dry by letting no water in. Of course, GTX doesn’t let water out too, so, if the water comes in over the top of the shoe, your feet will stay wet. Always with considering! However, over the winter months I could feel the benefit of the Gore Tex on cold days.

Niandi Carmont gets her claws out and test the new inov-8 Terraclaw 250. A shoe that offers a wide toe box, grip, cushioning and an 8mm drop for longer days on mixed terrain.
Please note all photographs in this review are the male colour ways . The ladies version as reviewed is below.
The Terraclaw is a great dual purpose trail shoe for “earthy” mostly dry trail as well as offering enough grip to be used on trail with moderately grassy/ muddy sections. As I’m not an aficionado of technical slippery and extremely boggy terrain, this is definitely the shoe to fit my foot in more ways than one.
What definitely makes this trail shoe even more attractive for me is the wide toe box or in inov-8 jargon “standard fit” as opposed to the “precision fit”. The roomy toe box allows my toes to splay comfortably as I’m running irrespective of any swelling in hot weather over long distances. This is an absolute must for me as like with many ultra-runners who have been in the sport for some time, I have an issue with a collapsing right arch and thus a wider right foot. In my case narrower trail shoes usually lead to chafing in between the toes and ensuing blisters.
Another interesting key feature of this model which attracted me is inov-8’s innovative patented Dynamic Fascia Band™ (DFB) technology. What this means in layman’s terms is that the anatomical position of the plantar fascia ligament is replicated and the function of the human foot’s ability to utilize the “windlass effect” is duplicated. As body weight moves forward onto the metatarsal heads and the toes begin to extend, tension on the inov-8 fascia band™ increases. When the heel leaves the ground, the inov-8 fascia band™ resists elongation of the medial arch and carries the entire body weight of the runner converting the shoe into a rigid propulsive lever. This helps the athlete to run more efficiently, more economically and thus a tad faster. How cool is that for an injured right-foot heel striker with a collapsing arch like me? I certainly feel I’m dragging my right foot less.
In addition to this the shoe is very breathable with a soft with a slipper-like feel. In fact this model is almost too comfy for a trail shoe! At 250G it is a relatively light shoe yet lightness is not sacrificed at the expense of cushioning. There is enough cushioning in this trail shoe to run on rock, gravel or stony terrain and inov-8 have got the balance just right and so if like me you still like to feel the ground underfoot you won’t be disappointed. The shoe sticks to inov-8 heritage of getting you low to the ground but the lack of a rockplate will allow more irregular rocks or sharper rocks be felt in the foot. It’s no great issue but one you should be aware of.
If you take a peek at the sole of the shoe, you’ll quickly understand why this shoe offers good grip on most terrain. Inov-8 have developed 5 distinct outsole compounds to deliver maximum grip on a wide variety of terrains and in changeable weather conditions. The Terraclaw outsole is composed of Dual-C, in other words a mix of medium sticky and hard sticky compound. This particular technology uses rock climbing rubber technology.
In principle the shoe should therefore also offer a reasonable amount of grip on wet rock. However, I was not convinced after having tested it on the initial section of the Garmin Mourne Skyline race course. Running down the wet stone steps was tricky and a shoe like the inov-8 Mudclaw 300 (HERE) would be more suited to that terrain despite the aggressive outsole. Personally from having tested the shoe on various terrains and in different seasons and weather conditions, I would say it is more suited to dry trail and trail with short road sections. The shoe transitions well from one to the other. It would perform less well on extremely boggy terrain, very steep and slippery grassy climbs/ descents (fells), stony river and waterfall sections. I also found the cleats wore away quite rapidly with over-use. I’m on my second pair in the space of 3 months as there is noticeable cleat wear where I heel strike and on the forefoot where the foot lifts off. Of course, if you use the shoe on just soft ground or trail, the outsole will last longer! However, I believe that inov-8 are trying to find a shoe here that does all jobs? The rise of ‘city-trail’ a key indicator why this move from inov-8 makes sense. But whenever you make a compromise, you very often end up with something that does nothing well. Certainly, if you want an out-and-out shoe for wet, muddy and slippery trail this is not the shoe for you: look at the 212 (HERE) or 300 (HERE). Equally, if you want a shoe for just road, this is not the shoe for you. But if you want a shoe that enables you to run road, run trail, have comfort and all with a pleasing drop of 8mm this is definitely worth considering.
The triangular spaced out lug design of the shoe is interesting too. The purpose of this is to release debris, grit and small stones. However I found that it was not effective in releasing big clumps of muddy grass which got entangled in the lugs. On the plus side because of the lug design the shoe is easy to rinse off after muddy trail runs.
The Terraclaw offers good toe and foot protection in spite of its light weight with a full rand and higher stack height. Like other inov-8 models the 2 Meta-flex grooves on the outsole (pinky-red color on the Ladies shoe) at the forefoot and the heel allow for natural foot flexing making for a smoother run.
It’s a neutral shoe that fits true to size but be warned, the roomier toe box may make the shoe feel a little ‘sloppy.’ If so, try lacing the shoe using this method HERE, it will hold your foot tight but still allow the freedom for your toes.
Last but not least – the color is great! Nice and sober – black with a hint of pink and blue. Personally I’m not one for garish bright run shoes which quickly look muddy.
I have tested this shoe on several types of terrain and in various weather conditions:
A 2-day ultra around the Isle of Wight with a total mileage of 117km in hot weather and on dry trail, road sections, grassy coastal trail and some short technical ascents. My conclusion: this shoe is very versatile – I had no issue moving from trail to road sections. The grip on dusty trail is very good.
A one-day 42km trail in Lanzarote running on dust roads, through very rocky lava fields, on beach sections in soft sand, on pebbles, on stones, gravel and up and down slippery dusty mountain sections in hot weather. My conclusion: the shoe offered great grip in dry conditions. I tend to be too careful and overly think technical descents but found that I had more confidence with the Terraclaw.
Wet muddy trail training runs in the Midlands in rainy cold weather. My conclusion: If the terrain is not too muddy the Terraclaw offers sufficient grip. However, I felt it lacked grip in extreme boggy conditions.
Training runs on the West Highland Way. My conclusion: Good shoe for this type of terrain which is not extremely technical and very runnable.
Wet training runs on the fells in the Lakelands. My conclusion: Again I feel the shoe does not offer sufficient grip on really boggy and slippery terrain.
Training in the Mourne mountains in Northern Ireland. My conclusion: The shoe was great on forest path and trail sections but lacked grip on wet rocky sections on descents and steep grassy descents. The Mudclaw 300 would probably be more suitable for this kind of terrain.
Training runs on forest path near Paris. My conclusion: The shoe is very versatile and transitions comfortably from hard road surfaces to softer forest terrain.
I like it – I’m already on my second pair.
The patented Dynamic Fascia Band™ technology favors a more economical and thus more efficient run style.
The Dual-C grip is sufficient for moderately wet conditions.
This model is extremely comfortable.
It is lightweight shoe with ample protection and great cushioning.
I love the roomy toe box.
Very versatile shoe – an all-rounder
I’m on my second pair. It lacks durability mainly due to lug wear.
It doesn’t offer sufficient grip in more extreme conditions
If you’d prefer the same show with a lower drop (4mm) the 220 version is available with a unique lacing style.
From single track to steep descents, the TERRACLAW™ performs on the widest range of trails imaginable. Our unique lug design releases debris and grit like no other, delivering optimum grip with every foot strike. The higher mileage version of the TERRACLAW™ range, this shoe delivers extra protection and comfort courtesy of a full rand and higher stack height.
The first few months of 2015 have been very rewarding and I have had several articles and features printed worldwide in a series of top ranking magazines.
From the rainforests of Costa Rica, to heat of the Sahara. Anton Krupicka looking broken at Transgrancanaria, Joe Grant between a rock and a hard place at The Coastal Challenge and Sir Ranulph Fiennes beating the heat at the Marathon des Sables.
