adidas Terrex Agravic Flow

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. 

THE SHOE

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.

IN USE

 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.

CONCLUSION

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.

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.
