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.
