inov-8 TERRAULTRA G270 Review

I first got a hold of the original TERRAULTRA 2-years ago, the G260. It was a groundbreaking shoe for inov-8 not only introducing a zero-drop shoe to the brands line-up but also paving the way for Graphene technology.

A great deal has happened in the past 2-years with Graphene appearing in more and more inov-8 shoes but interestingly no other zero drop shoes have been added to the line-up.

The TERRAULTRA G260 was warmly welcomed, particularly by any trail runner using Altra who now had a zero-drop alternative now available with a brand who really know how to make off-road shoes from a long history in the fells of the UK.

Now, the G260 has been updated and we welcome the TERRAULTRA G270.

On first glance, it could look like the same shoe. That green colour is somewhat distinctive! However, one does not need to look longer to see some immediate significant changes.

The upper, the lacing, the outsole and the cushioning all sort of look the same but they are not.

In the words on inov-8:

  • Graphene outsole has 4mm deep cleats all now armed with dispersion channels and rubber dimples to give better grip on wet and dry trails. Cleats are repositioned in key areas and flex grooves fine-tuned for agile sticky traction that lasts longer.
  • Cushioning is a new POWERFLOW MAX that has been increased by 3mm for a plush ride, improved cushioning and double the durability. A BOOMERANG insole apparently will increase energy return by 20 and 40% respectively over the previous model.
  • The upper has ADAPTERFIT which adjusts to the foot and the use of stronger materials will add to durability and protection.

The Shoe

With a fit scale of 5, this is as wide as you can go in an inov-8 shoe, So, toe splay and room at the front end comes no better.

Cushioning is 12mm front and rear providing a zero drop. Using POWERFLOW MAX.

The footbed is 6mm and the lug depth of the outsole is 4mm made of Graphene grip.

It G270 has the necessary points to attach a trail gaiter.

At 270g (UK8) the new TERRAULTRA is 10g heavier than the previous version.

Sizing is true to size BUT take into consideration the wider toe box, maybe (?) a half-size smaller would be better. I always use EU44/ UK9.5 and these were ideal for me.

FIRST IMPRESSIONS

The G270 is light and it’s clear to see some of the immediate improvements over the previous version. The lacing is flatter, the tongue is different, the upper is different, the toe box protection is increased, and the shoes have the flagship Graphene outsole that looks very different.

Zero drop is NOT for everyone, so, what makes the G270 great for some also make the G270 potentially unusable for others. This is not a negative comment, it’s just a heads-up to say, that if you have not used zero drop before, don’t be tempted to get the G270 and start racking miles up… You will almost certainly get sore Achilles, calf and potentially get injured. Like barefoot running, zero drop running needs to be learnt and the body needs to adapt. Typically, 6-months would be a good transition period. However, some zero-drop running (initially short periods) is great for improving run form, so, the G270 could be a nice new weapon in your shoe line-up?

If zero drop is your thing, then you will already have a big smile on your face.

Following on from the G260, the G270 has a wide toe box that echoes what brands like Altra have been doing for years. Toe splay is king and the G270 has loads of room for that. I had issues with the G260 in that I always felt I had too much room, the room at the front was made worse by the upper and lacing system not holding my foot how I wanted to compensate for the additional width, space and foot movement.

Slipping the G270 on I was initially worried, the space in the toe box was as much if not a little more than the previous version. However, as soon as I adjusted and tightened the laces, I immediately noticed significant changes. The tongue was a much better fit. The lacing was great improved, and I could really adjust the tension from top to bottom. The ADAPTERFIT pulled in holding my foot. Walking around immediately felt 100% better than the G260. My foot was being held reassuringly.

The upper is far more breathable that the G260.

The cushioning and bounce were notable and the outsole at this stage left me with many questions.

IN USE

The G260 was a little lifeless and felt flat. The G270 immediately felt different with a couple of miles on the road before hitting the trails. So, this was already a great improvement.

With META-FLEX at the front, the propulsive phase felt really good no doubt added to with the insole that inov-8 say increases energy return by 40%. I definitely felt some bounce, but 40% more?

The cushioning was noticeable, particularly over the G260 as was the zero drop. I use zero drop shoes occasionally, but always prefer 4/5mm for faster and more technical running and if going long, 8mm works perfect for me. So, considering the G270 is designed for long-distance running, zero drop would be a challenge for me.

The wide toe box still feels mega wide (too wide for me) BUT the lacing and ADAPTERFIT allowed me to compensate for the room at the front by tightening appropriately. However, I did fine once or twice I over-tightened the laces only having to stop and loosen them a little.

The transition from road to gravel trail was seamless and comfortable. The TERRAULTRA is an out and out ultra-shoe designed for trails that are more groomed, say Western States in the USA or UTMB in Europe. So hard packed single-track felt really good in the G270, equally rocky and stoney ground felt good.

Running up hill surprised me. The META-FLEX allowed for great flexibility and propulsion, but it was the outsole that really gripped. A massive improvement over the G260.

I have to say, I have not always been a fan with the addition of Graphene. At times, I felt it compromised the sticky outsoles and made them less grippy, albeit providing longer life. But on many occasions, for me particularly, grip is king and if it is compromised, I am not happy.

Here, in the G270 there was noticeable difference, and this was coming from just 4mm lugs.

The test of course would really come when I threw in some mud and wet rock.

Gladly, mud (loads of it) rocks, tree routes, climbs, descents, wooden planks, forests and yes, a little fire trail all make up my daily and local runs. So, throwing the G270 in the thick of things was easy to do. And yes, I was being unfair as I actively searched out and aimed for steep rocks with water on them and I aimed for every puddle and sloppy mud I could.

I was impressed.

At times, I would think to myself, almost wanting the G270 outsole to fail;

‘This will get them… wait for the slip!’

But the slip never came, especially on dry and wet rock. On a 3-hour run, as the minutes clicked by, I started to relax more and more and eventually stopped worrying and asking;

‘Will the G270 grip here?’

They did, at all times provide me with the grip I required.

Surprisingly, in really sloppy mud, I did not slip or move as I had expected. Partially due to the fact that I did apply the brakes a little and respect the conditions.

Technical trail is where the G270 shows some flaws. The wider toe box lacks precision, allows one’s toes to move and therefore I felt that there was just ‘too much’ shoe to navigate between rocks, roots, stones and a plethora of other obstacles. But of course, I am being unfair! The G270 is designed for less technical trails, long hours and all-day comfort – that they do really well!

The shoes are responsive and do work well when running fast. However, the wide toe box, zero drop and cushioning do make them feel a little like a saloon car… Plenty of room, comfy seats, and can get the miles done. But I craved a more performance car at times with more precision, tighter handling and a little more fire and daring, especially when coming of road, fire trails or single-track.

The cushioning was plush and considering it is only 12mm, it felt like more. Especially noticeable extra comfort over the 9mm G260 which also was a little hard and lifeless. One thing to note, I found on tree routes and some stones, I could feel them in the bottom of my foot, so protection from obstacles is minimal. The toe box though has a good bumper and that worked really well.

The heel box was noticeably secure on the flat and going uphill, I had little to no slippage.

SUMMARY

Damian Hall just ran 260-miles on the Pennine Way in the G270 and set a new FKT, so, that gives some indication of the intended use of this shoe. Having said that, the Pennine Way is not all single-track and wonderful cruising trail, so, the shoe can handle the rough stuff too.

I was impressed by how versatile the 4mm Graphene outsole worked. There has been some significant improvement over the G260 and in the Graphene outsole in general.

The upper, lacing and tongue now really hold the foot and that for me is essential, especially with such a wide toe box. The toe box is one of the key selling points of this shoe. It allows toe splay, plenty of room and flexibility for a foot to swell wider with accumulated miles.

The cushioning increased from 9mm (G260) to 12mm for the G270 is noticeable. More importantly, the G270 now has life, the G260 felt a little dead.

CONCLUSION

The G270 is a marked improvement over the G260, so, if you liked the previous model you are going to love the latest incarnation.

Zero drop and a wide toe box will be exactly what some people are looking for and they will have a big smile on their face. For me, and this of course is very personal, I can’t run in zero for hours and hours and I feel that the toe box is a little roomier than it needs to be.

So, imagine a Trail Talon 290 made like a TERRAULTRA G270 – slightly narrower toe box (4 fit) 8mm drop; 11mm and 19mm cushioning and this Graphene outsole – that would be a winning shoe IMO. (inov-8 take note)

The G270 is a winning shoe and all packaged perfectly for ultra-distance runner who needs grip, cushioning and comfort for the long-haul out on the trails. It would even make a great road shoe if required.

For multi-day adventures, such as Marathon des Sables, just like the Trail Talon, the G270 would be really excellent.

If technical trail and mud is your thing, this is not the best shoe for that, however, it can handle it remarkably well, so, if you only wanted one trail shoe (with zero drop) to do all, the G270 would be ideal. By contrast, if you wanted a one-stop trail shoe with 8mm drop, I recommend the Trail Talon 290.

inov-8 TERRAULTRA G 260 #Graphene – First Impressions

It’s a new phase in the history of inov-8, for over 10-years the UK based brand have pioneered shoe development for running. Now, in 2018, they launch products with Graphene – a new material that is lighter and more long-lasting than previous 

Three models are currently available:

F-Lite 290 G

Mudclaw 260

And the Terraultra G260 which I am currently testing.

The Technology

Graphene – is an enhanced rubber that offers grip and longevity. Previously, a soft rubber has provided grip but you always compromised on the outsole life. Graphene looks to change that! It is 50% stronger, 50% more elastic and 50% harder wearing.

Kevlar – The upper is made of a breathable mesh with Kevlar overlays. Kevlar has been used in bulletproof vests.

The Shoe

Out of the box, it’s noticeable how light this shoe is, the ‘260’ refers to the weight of the shoe (as with all inov-8 shoes) in a standard UK8 size.

I wear a UK9.5 and the G260 is true to size. Shoes by inov-8 are now scaled 1-5 for width, 1 being narrow, 5 being wide. The G260 is a ‘4’ but I would say it may almost drift to a ‘5.’ Importantly, if you need a wide toe box or need a wide toe box, these shoes will appeal.

Notably, the G260 is zero drop. This is a bold move by inov-8 and I will be interested to know if they plan to expand the G260 shoe with 4mm and/ or 8mm drop? Certainly, there has been much demand and request for a zero drop shoe, and although a zero drop version of the G260 makes sense, I am surprised not to see a 4 and 8mm drop versions. This is particularly relevant due to the intended use of the shoe. This is an out-and-out trail shoe designed for long run days. I personally prefer a 8mm drop shoe when running longer… but hey, that is me!

With 9mm of cushioning, the G260 is a comfortable shoe with adequate cushioning for long trail days for runners with good run form.

The upper and the outsole is where we really see the technology. The upper is very impressive and very resilient – it is very strong with breathable mesh and Kevlar overlays. The outsole is the star of the show and is hard wearing and offers excellent grip. This is the Graphene technology! As this is a trail shoe, the outsole has grip (4mm lug) but it is not aggressive, it’s a shoe that is designed for all surfaces in wet or dry but not for mud. If you are running in mud you need a different shoe, for example the Graphene Mudclaw 260.

First Impression

Green. That was my first impression. Yes, theses shoes are GREEN. Ain’t no hiding in these shoes and although they would not be my chosen colour, I can see why inov-8 have chosen this colour for the three new Graphene models – they stand out and are easily noticeable.

I mentioned above that they are light. They are, super light.

Slipping them on I immediately noticed how wide the toe box is, considering these are zero drop shoes, I can certainly see Altra shoe users moving over or at least being curious as to how the G260’s run. For me, the ‘4’ width fitting could even drift to a ‘5’ based inov-8’s width fitting scale – I found them very roomy.

The lacing eyelets are fabric stitched through into the upper and the all important additional eyelets are added to the top should one with to ‘lock lace’ or using a simulated lacing technique. I really disliked the laces. I don’t know what it is about them but they always wanted to loosen off, for me anyway. That is just annoying. It’s a minor problem which easily rectified.

The tongue is sewn into the shoe and gusseted. This is great for keeping out debris and providing a secure and welcome foot hold. I found with the wider toe box that I wanted to pull my laces a little tighter than normal to give me a secure and confident feel.

The upper is made of a green breathable mesh and the structure/ rigidity of the upper is created by Kevlar overlays. Notably, Kevlar is the toe protection and then it spreads out like fingers on the side of the shoe to the laces. Pulse the laces tight and the Kevlar pulls in and provides the hold for the foot. Inov-8 have added gaiter eyelets on the rear of the upper should you like to add the optional extra. A solid green band extends around the rear of the shoe, again adding some structure and stability.

The heel box is plush and like all inov-8 shoes I have tested, is very comfortable, run free and provides a firm and secure hold.

I always try to wear any new shoes for a day at home before going for a run. It helps me decide if there will be any issue points and it also helps bed the shoes in. The G260 was our of the box comfortable – really comfortable! I have to say, I am not a zero drop runner, 3/4mm is usually as low as I go. I actually questioned if the G260 was zero drop, they didn’t feel like it. But when I put an 8mm drop shoe on, I really noticed the difference.

My first run was a standard 12km loop which I use for all shoe tests, the reason being is that it has a little of everything. It starts and ends with 1-mile of road at the beginning and end. It has 4km of canal toe path and then what follows is a mix of trail, rocks, stones, forest path, single-track, climbing and descending.

On the road, the G260 felt really great. So much so, I wouldn’t hesitate doing a road run in them. I was conscious over the early mile to run with good form. My mind was telling me I was in zero drop and therefore my technique needed to be good. However, as in my apartment, the run experience was telling me I was in a low-drop shoe, but not zero.

The canal path section was ticked along and after a very dry and sunny patch of weather, the trails were very hard and the G260 flew along them. On the single-track sections and climbing, the shoes performed solidly. Grip at all times was secure and confident. 

Running a long descent is when I really noticed the wide toe box. I had less control than in a precision shoe, but my toes splayed well. They were too wide for me!

As with many inov shoes, they have Meta-Flex, this allows the shoe the bend at the front and those therefore helps with the propulsive phase and toe-off. I found the G260 very flexible.

By the end of the first run, I had run 12km in 65 minutes and had had no issues. On the contrary, I was really impressed with the G260.

After 140km

I have used the G260 on alternate days since receiving them, the primary reason for this being is that zero drop is not my chosen drop, so, I wanted to make sure I reduced the risk of picking up an injury. However, every time I have gone for a run, I have wanted to use the G260 – yes, I like them that much.

They give a very different feel to my current favourite shoes and ironically they are all 8mm drop.

The longest I have run in the G260 is 2-hours and that for me currently feels far enough. I definitely think about my run technique more when using these; no bad thing! But that is mentally tiring. For those who always run zero drop, I think you are going to find the G260 a revelation.

The outsole and upper are showing no signs of any wear at all but I guess with only 140km covered, it is too early to give judgement on long term life. I will come back to that in a month.

It’s a shoe that feels very much of an all-rounder, one that can handle road and trail. In dry conditions I am really impressed, grip is excellent. I haven’t been able to test in the wet as we have had no rain, so, I will have to come back to you on that one.

The cushioning at 9mm is adequate providing enough comfort but not so much that a feel for the ground is compromised. However, on rocky ground, particularly with small stones, I could feel them! There is no rock-plate so you feel a great deal. I also found the cushioning a little lifeless… Some sparkle is missing? It’s fair to say, that with zero drop, the G260 is aimed at efficient runners, so the cushioning should be ideal.

Upper and fit are excellent, I have had no hot spots and the gusseted tongue is a winner. Heel box is perfect holding the foot secure at all times, be that running downhill, climbing, walking or running. I really disliked the laces so I replaced them. On occasion I have ‘lace locked’ the shoes to provide a more secure and firm hold of the foot.

For me, although I enjoy a wide toe box, I would say these feel a little too wide. I am noticeably pulling the laces in tighter to provide a more secure feel. So, if you like wide or need wide, the G260 should be a great shoe for you.

Summary

Early impressions are really good of the G260 and I am absolutely convinced it is going to appeal to many. I personally would use the shoes daily if it were not for the zero drop, but that is me! I am certainly going to be interested to see if 4mm and or 8mm drop versions become available?

The more aggressive Mudclaw 260 Graphene version has 4mm drop and the classic 8mm studs, so, if mud is your thing, you have an option to the G260.

However, if you want one shoe that can do everything well (not sloppy mud) in a zero drop, the G260 is a shoe for you to consider.

Personally, several issues are worth considering: 

  1. The toe box is wide and maybe too wide for some. 
  2. I found the cushioning a little lifeless? 
  3. At 9mm cushioning this is a shoe for efficient runners.
  4. Zero drop is not for everyone.
  5. So far, the Graphene and Kevlar are doing the job that inov-8 say – good grip and less wear and tear.

I will feedback more after long-term testing.
