Inov-8 Terraultra G 260: Versatility, durability and grip but don’t expect a cushioned rideMore photos
The TerraUltra G 260 is a really comfortable well designed and robust shoe, and there’s every chance that it may get close to the 1000 miles that Inov-8 promised.
The shoe is designed for Ultra-distance running and combines an upper which is spacious in the forefoot with a responsive midsole and versatile outsole. This makes it a great choice for long runs, especially those that involve a variation in terrain.
The TerraUltra G 260 has also become my all-rounder for easy off-road runs on anything but hard-packed surfaces, though I’d leave it at home for faster stuff.
If you're after a versatile off-roader which will keep your feet comfortable hour after hour, then this could be the right choice for you. Just as long as you're happy with a minimal feel without an awful lot of cushioning.
- Spacious, breathable upper
- Excellent outsole grip and traction
- Responsive ride
- Minimal cushioning
- Laces could be improved
The Inov-8 TerraUltra G 260 is one of the shoe company’s new range of shoes incorporating graphene-enhanced rubber within its outsole. It is marketed as “the world's toughest shoe for running the world's toughest long-distance trails.”
The phrases “tough and toughest” are peppered throughout the marketing for Inov-8’s new Graphene range, but this shoe really is more than just an off-road shoe with a robust sole, and in some ways it’s a shame that the marketing seems to focus solely (no pun intended) on this aspect of the shoe.
As the name suggests, the Inov-8 TerraUltra G 260 is designed for running long, but it really is more versatile than that.
The upper is far more spacious than most of the Inov-8s range, especially in the toe box. The midsole offers shock absorption rather than cushioning, together with a little more responsiveness than some of their shoes that are designed for more technical terrains.
The shoe is also lighter than many of Inov-8’s range, and the relatively low lugs of the outsole are designed together with grooves in the midsole to offer flexible sole that is a more forgiving on the foot than some of their technical shoes, whilst retaining a good feel for the ground, and a confidence on a range of terrains.
I am lucky to be able to run in the mountains of Snowdonia and around the coast of Anglesey. This can throw up a variety of terrains in any single run, and I was looking forward to finding out whether this shoe could handle them all!
Over the last few weeks, I’ve run around 70 miles in these shoes, subjecting them to a wide variety of terrains including forest and hard-packed trails, mountains and beaches, and even a fell-race. The longest run I’ve done in them is around 3 hours, so whilst I can’t speak for the truly long-distance feel of the shoe, I feel that I’ve tested them out thoroughly enough to review them.
First impressions & appearance
The TerraUltra G 260 is a great looking shoe which is fortunate because it’s also a shoe that you can’t miss in Inov-8’s Graphene inspired bright green with only an occasional hint of black.
The shoe does initially look more like a rugged road shoe than Inov-8’s usual off-road fare, but this is primarily due to the wider forefoot and the visible foam of the midsole.
Picking the TerraUltra G 260 out of the box, it feels light. In part, I think that this is because the weight is evenly distributed around the shoe, whilst other shoes such as the Roclite or the Mudclaw have a heavier-weight outsole which can initially make the shoe feel heavy when handling.
Handling the shoe initially, I was surprised at how thin Inov-8 have been able to make the outsole; the grip provided by the 4mm lugs are enhanced by grooves in the Exteroflow Foam midsole, and I’m sure that the graphene within the rubber allows for a thinner rubber outsole without compromising the durability.
The TerraUltra G 260 is listed at 260g (hence the name). Whilst not truly lightweight, this comparable to a road-running shoe in terms of weight, and lighter than many shoes of this type.
As expected, my UK 13 (14.0 US) shoe weighed in heavier at 312g, which is a more modest increase in weight than many shoes.
Most importantly, the Terraultra G 260 feels light when running. I think that this is as much to do with the weight distribution mentioned above as the number on the scales. Designed for running long, the lightweight nature of the shoe is going to be an important factor as the time and distance increase.
My UK size 13 fit just right, with no need to size up, and given that the shoe is designed to allow swelling of the foot. My suggestion is that most runners will find the shoe true to size.
I’m used to a snug Inov-8 shoe which holds the shoe securely through even the steepest of technical terrains. I do much of my off-road running in a Roclite or the Trailroc shoe, or a Muclaw for very wet and muddy conditions.
The TerraUltra is a little different, however. It comes in as a “5” in Inov-8’s width guide (the widest shoe), compared to a “3” in my regular.
This additional width allows the foot to swell, and for the toes to splay, especially over long distances. It also comes as a welcome relief to someone who suffers from the occasional flare-up of Morton’s neuroma.
Despite the additional width, I did have to loosen off the laces significantly to get my foot in, and this is because the foot is held well around the ankle and heel.
This means that while the forefoot can enjoy the extra room, the foot is safely locked in at the back, preventing the foot from moving forward and the toes from hitting the front of the shoe on even the steepest descent.
My only real issue is with the laces. I really struggled to get them to tie securely.
This was for two reasons. First, the laces just aren't long enough to tie in a double knot when using the top lace holes (this may not be an issue with smaller size shoes), and the round "springy" laces just don't feel secure when tied.
This accompanying photo happened to catch a time when the laces had come undone whilst running.
In a shoe with a sole designed to last 1000 miles, it's essential that the upper can last the distance too. This is especially important in an Inov-8 shoe, given that the company has not always produced shoes with the most robust upper.
Having said that, my Roclite 290 and Trailroc 270 shoes have both around 500km of running on them (mainly mountain running where 500km translates to much longer on the feet than in a road shoe).
Aside from an occasional application of superglue to the lace loops of the Roclite, they have stood up well, though I couldn’t see them lasting the same distance again.
Inov-8 have addressed questions over the durability of the upper by incorporating Kevlar Aramid Fibres (think bulletproof vest) into the heel cup and with noticeably robust overlays forming the "Metracradle" which wraps the midfoot, and the toe cap at the front of the shoe.
Added to this, the breathable mesh that forms the mid and front sections of the upper feel more durable than in other Inov-8 shoes, and there's a good chance this upper may last the 1000 miles that Inov-8 claims.
So in detail…
The heel cup is more robust than a standard Inov-8 shoe and solid enough to hold the heel firmly, whilst also allowing the heel to move with the foot over variable terrain (it does not incorporate a solid plastic heel cup as in some shoes).
Cushioning in and around the heel cup is similar to most Inov-8 shoes I have experienced; not a great deal, but sufficient for comfort.
The Kevlar Aramid fibers should ensure continued durability, and there is a plastic overlay into which the Inov-8 gaiter can be secured.
This is important where gaiters will be worn as the sole of the shoe will not really accommodate the elastic gaiter straps which would be the alternative method of securing them.
The tongue offers more cushioning than in most Inov-8 shoes, and this is no doubt a nod to the fact that this shoe is designed to be worn for many hours, and this extra padding will allow for the midfoot to be held securely without compromising comfort.
The tongue is secured at the bottom and most of the sides to prevent debris from entering the shoe. Overlaid across the midfoot mesh is Inov-8’s Metcradle to which the laces are tied, and which again holds the foot well without preventing movement.
In the case of the TerraUltra, the Metcradle is the most comprehensive yet. The overlays begin at the front of the heel cup and continue right across the midfoot with the foremost one overlapping with the toe cap at the front of the shoe.
The toecap is fairly large on this shoe and appears to be constructed from some form of reinforced engineered mesh rather than a rubberized compound which is found in much of Inov-8's shoes.
In use, it does offer a good level of protection, and I would imagine that this method of construction helps to reduce the weight of the shoe. The most significant aspect of the front of toebox is the space for toes to move and splay.
Inov-8 claim that the Exterofit upper “adapts to the natural swelling and movement of the foot when running long distances”.
Terraultra G 260 definitely feels very different from my other Inov-8 shoes where the entire foot feels very snug. Here, the forefoot is allowed space to move and breathe.
The midsole uses Inov-8’s Enter flow foam, and significantly offers “zero drop”; that is, no difference in depth of the foam between the heel and the forefoot, with a midfoot stack at 9mm from front to back.
According to Inov-8, this “next-generation underfoot technology strikes the perfect balance between comfort and responsiveness.”
The appearance of the shoe, and especially the midsole is that of a hybrid road/trail shoe, but do not be fooled into thinking that there is a tremendous amount of cushioning in this shoe.
Think shock absorption rather than cushioning. The 9mm of Exteroflow foam will reduce the impact of the foot on even the rockiest of terrains, but you will retain ground-feel throughout.
My personal view is that whilst this lack of cushioning may not be an issue with the elite and front-of-the-field runners, there will be many mid-field and back-of-the-pack runners who find that they would prefer a more cushioned shoe as the miles and the hours build up during an ultra race.
The responsiveness described by Inov-8 comes from a combination of the Exteroflow foam and the Dynamic Fascia Band integrated into the outsole of the shoe, and which replicates the plantar fascia ligament to deliver a “windlass effect.”
With its origin at the heel, the Dynamic Fascia Band extends forward and divides into individual bands as a similar manner to the plantar fascia, stretching as the heel leaves the ground and propelling the body forward at the beginning of each stride.
This is where the Graphene enhanced rubber is used to provide “the world's toughest grip on hard-packed trails.”
The design of the outsole is really interesting, with a comparatively thin layer or rubber for such a shoe, and one that is integrated with the midsole to enhance the grip and deliver good flexibility and ground contact.
The lug depth on this shoe is relatively shallow at 4mm. But this is combined with grooves in the midsole to effectively double the tread depth, making it more effective than it, otherwise would be even in loose and muddy conditions.
The location of the groves, both laterally and in the front to back plane, combine to make this shoe flex in all directions as the foot lands. This is especially important of uneven and rocky terrain where it ensures that as much of the sole as possible is in contact with the ground through every footfall.
The innovative design, graphene rubber and the integration of the midsole and outsole have combined to create an incredibly versatile sole unit which provides confidence in pretty well all conditions and terrains.
This is a great shoe - not just for long-distance ultra-marathons (as the name suggests), but also for shorter runs on a variety of terrains.
It will cope with fairly technical routes, though at speed, the foot will move around a little too much for my liking during quick changes of direction at speed. I love the outsole/midsole design and would really like to see it on a precision shoe in the future.
This is a shoe designed for running long. I’ve now run close to 100 miles in this shoe, but I should admit that the longest I’ve run to date is around 3 hours on fairly mountainous terrain. I’ve used it on a variety of surfaces including woodland trails, sand, hard-packed trails, gravel and fell and feel able to comment on its performance.
Many of my off-road runs begin with a little time on tarmac, and as mentioned above, this shoe provides shock absorption rather than cushioning. As a larger runner (6’2” and currently 90kg), it really isn’t a shoe I’d use for any distance on hard surfaces.
Once off-road, the design of this shoe really starts to show through. Inov-8 claim that the shoe delivers a balance of comfort and responsiveness, and that really is how it feels. Aside from the occasional particularly sharp rock, the tough outsole and Exteroflow midsole protect the foot from the terrain.
At the same time, the sole is flexible enough to wrap around larger rocks, stones, and changes in the surface to maximize the ground contact at all times. The result is that the shoe provides the type of confidence that you’d expect from a more technical shoe such as the Roclite or Trailroc.
On more even terrain, when you can begin to increase the pace a little, the responsiveness kicks in and the shoe helps you to move faster, all the time maintaining the confidence provided by the midsole/outsole combination.
The shoe does, however, has its limitations at a faster pace and is obviously designed for ultrarunning. The heel and to an extent the mid-foot is well held by the shoe, but the front of the shoe and toe box are deliberately wider than many of their shoes and allow movement of the forefoot.
For review purposes, I wore this shoe on a short fell race a few weeks ago and found that the foot will move around a little in the shoe if you try to take tight turns at speed, especially on a steep descent.
I mention this only as an observation. The shoe isn’t designed for this purpose, and Inov-8 have many far better models for fell-racing!
On forest tracks, this shoe makes you feel as if you can run all day; light, responsive, and with more adequate cushioning for this type of surface.
Up in the mountains, the shoe copes really well with rock, stone and grassland alike. Its weight is a real benefit as you tire, but still, need to lift the foot up and over, or onto obstacles. The longer you run in this terrain, the more you’ll be glad that you chose to wear the TerraUltra G 260 rather than a precision-fit shoe.
The shoe easily copes with sand and gravel, and the wider footprint, especially at the front, helps to limit the sinking of the foot on these surfaces, and anything that can reduce the energy-sapping nature of such surfaces even a little has to be a good thing.
If you are running long on hard-packed trails, then you may have a decision to make. I have no doubt that the closer you get to the front of a race, the more this shoe will suit you on this type of trail.
If you are a little further back, however, or a heavier runner, I'd suggest that you may want to look for a shoe with more cushioning than this shoe provides especially as the time and miles stack up.
Finally, I should address the “zero drop” nature of the shoe. My shoes tend to vary in the heel-toe drop, from a 10mm Brooks Ghost for long-easy runs on the road to a 4mm Roclite or Trailroc for mountain running, so I am by no means an advocate of zero-drop shoes.
I tend to find that the drop on shoes becomes less relevant in off road running, and especially on more technical terrain where the angle and position of the foot changes with every footfall.
As such, I didn’t find any problems running in the zero-drop TerraUltra G 260. Having said that, if you’re used to higher drop shoes, I’d suggest getting used to running with zero drop over long distances before heading out on your first ultra with this shoe!
I really like this shoe, and it quickly becomes my first choice for easy off-road running on most terrains. For faster sessions, especially on more technical terrain, I’d still opt for my Roclite shoes, or Trailroc for dry, rocky routes.
This is a really comfortable well designed and robust shoe, and there’s every chance that it may get close to the 1000 miles that Inov-8 promised. The zero drop will appeal to many, but shouldn’t put off those who may be concerned about the transition; take a little time to get used to it and I’m sure you’ll enjoy the ride.
The shoe is designed for Ultra-distance running, and the spacious upper combined with a responsive midsole and versatile outsole make it a great choice for long runs that may involve a variety of terrain.
The key consideration as to whether to buy this shoe will be about how much cushioning you will want in a shoe, which you may well choose to run for hours. In conclusion, this shoe really works, and it's not one to be left in the box and taken out only for ultra-long runs.
You can enjoy the shoe for those easier days out on the trails and in the mountains knowing that your feet will appreciate the change to breathe and spread out a little, whilst the sole will work well on almost any terrain.
Are you a zero drop ultra trail runner? Then you need to check out Inov-8 TerraUltra 260g!More photos
When I first learned of the TerraUltra 260g, I knew I simply had to own a pair. On paper, it ticked all the right boxes - grippy, zero drop, rugged, wide last (and Inov-8!). As soon as they became available, I scoured the web for a deal and forked out the £s mail-order straight from the UK!
After a few days, they arrived, and I immediately took them out for a run. I was disappointed! It was not the wide zero-drop version of my beloved X-talon I was hoping for. They were stiff, heavy, bugged my pinky toes and way too warm.
Neon-green or not! Trail running shoes are not for the catwalk - they are tools and supposed to be covered in dirt!
Having paid a lot of money for them, I decided to use them for "variation." So for a couple of months, I only took them for the occasional run. After a while, as summer turned to autumn, I found myself more and more often unconsciously picking the TerraUltras.
Not only because I felt I had to, but because I wanted to. Come winter they were regulars in my shoe rotation. Just weeks ago I opted for the TerraUltras when doing a 50 miler (the Salomon Hammer Trail Winter Edition).
What had changed? How come a shoe that I didn't like much suddenly had become my "go-to" ultra shoe. Read on to learn why!
I don't know why Inov-8 decided that the signature color of their Graphene range should be neon-green. But at least they have been consistent with the 260g, which is a mixture of mostly neon green and a bit of black. They do stand out from the crowd, but I'm not entirely sure I like it much.
The TerraUltra 260g sports a zero-drop, and this is not for everyone to enjoy. But if you (like me) prefers a low or zero-drop, they are a welcome addition to a rather narrow niche of mildly cushioned zero-drop shoes.
Especially when it comes to grippy trail shoes, we zero-droppers are not exactly spoiled for choice. We are pretty much "stuck" with a few brands and models.
The TerraUltra 260g is, as the name implies, constructed with ultra running in mind. When you need to go for hours on end, your shoes must be comfortable.
For me, a key to comfort is plenty of space for my toes to splay. The TerraUltra provides that space nicely and comfortably. Not too roomy, not too narrow, just perfect (for me).
Well, not all was rosy at first! As mentioned in the introduction; the TerraUltra 260g was not overly comfortable to start with. Mainly because the upper was too stiff and kept bugging my pinky-toes.
Not as much as the X-talon 212 (precision fit), but enough for it to be annoying. The break-in period lasted longer than usual - some 150 km, but by then the upper had softened sufficiently.
After that, the toe-space seemed ample, and my toes and feet, in general, are very happy with the TerraUltra 260g. No hot-spots! Overall the TeraUltras with a significant break-in mileage become some of the most comfortable running shoes I have ever owned/tried.
They are now my "go-to" shoe for pretty much any type of terrain and trail. In particular, when I know, I will be running for more than an hour.
The tongue is sufficiently long and not overly cushioned yet still very comfortable. It is of the "semi-open" type. By that, I mean that the tongue itself is an independent unit, which is sown on to the upper via 2-3 cm wide elastic fabric.
This allows the tongue to shift and move with your foot, yet still, keep out debris and sand. With a gaiter attached the TerraUltra are superb at "keeping out nature."
The seams along the side of the tongue have been set rather clumsily.
The tongue is not all good though. They have seams from the top and down along each side. Those seams have (at least on my pair) been set rather clumsily.
Because of this, the tongue has an inherent tendency to fold back (in) on itself when I put them on. The folded tongue is extremely uncomfortable for the instep, and near impossible to straighten once the shoe is on.
By trial and error, I have found a way to put them on. I have to untie them very thoroughly and gently insert my foot while at the same time inserting a finger between the tongue and the instep.
If I don't use this technique, the tongue will fold on me, and I have to start over. This makes putting them on a bit of a project. However, they provide a snug, comfortable and secure fit once they are on.
The upper consists of two different fabrics. The inner layer a soft'ish breathable fabric, which is nice and hugging against the foot. On the outside of that is an outer webbing of kevlar enforced Cordura-like nylon.
The breathable inner upper is exposed between the structural blackish/green kevlar enforced webbing. Please note a seam has started to break in the bend zone.
The outer layer (webbing) is very stiff and offers great support, protection, and structural strength. The softer, breathable inner fabric is exposed between the outer webbing, and this allows for excellent drainage and ventilation. Mind you, despite their breathable qualities I find the TerraUltras are at their best in cold conditions (autumn, winter).
The upper is supposed to be water-repellent, and at first, they held out water nicely. But after 375 km they no longer work that way - especially in the "bend-zone" around the forefoot. My trusty old X-talon 212 standard fit (upwards of 500 km) still repels water a lot better than the TerraUltra 260g does.
The heel cup is very much like the X-talon. Simple, thin, hard and snug yet comfortable - perfect! The ankle collar sits a teeny bit higher than on most running shoes. But not enough to hit my malleolus. A high collar is good for keeping out water, mud and other geology/biology.
The laces on the TerraUltra 260g are quite thick and round. They are rather "slippery", and unless I wear gaiters, I have to tie double-knots to prevent them from sliding open every once in a while. Once the laces are tied properly (double knot) they hold your feet very comfortably and securely fastened for hours.
The graphene outsole has offered a superb grip in pretty much all conditions I have tried. Grassy, slippery, gravelly, rocky, muddy, sandy, icy ... been there, done that! I have only had the occasional slip on very steep, icy patches. Then again, anything but studs or chains would slip in those kinds of conditions.
The TerraUltra 260g leaves little room for a classic "strap-underneath"-type gaiter.
One very minor issue with the outsole is that the lugs are not overly deep. If you plan on running through some really deep mud, I'd recommend going with the MudClaw or X-talon instead.
Apart from deep mud, the TerraUltra will handle any type of terrain/condition. This is especially nice in trail ultras where you are likely to experience a range of conditions. Sandy, slippery, rocky, technical even the odd bit of tarmac - the TerraUltra does it all - and does it well
I'm used to shoes with little cushioning, e.g., X-talon 212, 200, and TerraClaw 220. In comparison to these, the TerraUltra is rather beefy and takes away a lot of the ground-feel at first.
With time and practice, the ground-feel has improved markedly. At their current stage, I find that the TerraUltra offers a superb combination of protection/support without drowning out the ground-feel completely. It is not a minimal shoe in any way - but you still have a "fairly good touch."
The TerraUltra do not offer much "springy-ness" - like most ordinary running shoes. For the urban runner this is not optimal - but for the rugged trail ultra, it is perfect. Again the TerraUltra is made for trail-running - not tarmac.
The TerraUltra 260g sports the Inov-8 gaiter attachment system introduced with the TrailTalon, and now pretty much standard on all Inov-8 trail shoes. Tiny up-side-down pockets that match the Inov-8 gaiter hooks hence moots the line/wire underneath the shoe.
Unfortunately, the pockets on the Terra Ultra 260g are not open at the top end, and not nearly deep enough for a secure hold using my old Race Ultra gaiters.
This also means the gaiters only have to travel a short distance downwards to detach themselves. Hence, they come off easily if you happen to run in thick brush or other uneasy terrains that might cause a slight downwards push.
The gaiter attachment pockets on the side of the shoe are too shallow.
One particular issue with my pair though was that I had to pry open the "gaiter pockets" on the outside with a sharp knife because they were completely glued together from the factory.
Please note that when it comes to gaiters, the outsole of the TerraUltra is flat and solid throughout. Plus whatever little space there is between the lugs is angled the wrong way. Thus, most traditional "strap-underneath-type-gaiters" (e.g., Inov-8 Debris gaiter or Salomon high/low gaiter) is not a viable option.
Inov-8 claim in their marketing material that the TerraUltra 260g is the toughest trail shoe, and will last 1000 miles. This for a running shoe rather extreme mileage should be accomplishable thanks to the kevlar enforced upper and the graphene-enhanced outsole.
At first, I felt quite convinced by the marketing material that Inov-8 was on to something. The entire feel of the shoe was also very solid at first.
But after some 375 km, I see a significant amount of wear on both the outsole and the upper. A visual inspection of the outsole shows that the lugs are not even anymore. Especially at the back of the heel and around the forefoot the lugs have clearly grated away.
Visible outsole wears on the heel of the TerraUltra 260g after only 375 km.
Wear and tear on running shoes is very individual - both the type of runner and the terrain/ground has a significant impact. However, I don't think I have abused my shoes beyond what is to be expected - neither gait-wise nor ground/terrain-wise.
There are also clear signs that the seems/fabric around the "forefoot bend" has taken its toll too over the first 375 km (See image 1). I'm quite certain it will break way before I reach 1000 miles.
I guesstimate the TerraUltras have to be retired sometime around a 1000 km (not miles). Which coincidentally is what I usually get out of my Inov-8 shoes.
The TerraUltra 260g is not the fastest shoe around - quite the contrary! On average, my usual everyday training runs have been 10-20 seconds slower per kilometer when wearing my TerraUltras. I don't think this is only because I pick my TerraUltras for technical and difficult runs: I have taken them pretty much anywhere.
My pair currently weigh in at 262 grams each for size UK 7. This is 20 to 80 grams heavier than most of my other shoes. That might explain some of the speed difference, but I don't think weight is the sole reason.
I speculate that the shape of the shoe - zero-drop, un-twistable arch, and the rather stiff midsole to some extent also influences speed. This, however, is likely to be highly personal, and other runners may experience less of a slow-speed effect than I have.
To me, it is only natural that stability, support, and comfort takes precedence over speed in a shoe that is designed for ultra running. And when it comes to comfort, support, and consistency during an ultra, I can highly recommend the TerraUltra! They are simply eminent!
I have taken mine as far as 50 miles in very varied terrain on a wide array of surfaces. Usually, I get "ultra fatigue" in my feet around 6-8 hours - perhaps you know that "tired" numb-ish feeling, especially in the footpads. With the Terra Ultra 260g, my feet just keep feeling fine and fresh throughout the race.
Another great thing with the TerraUltra is that they are true-to-size and very stable. Somehow they've managed to make a wide footbed feel compact.
Furthermore, the center of gravity sits low. Hence, they are very stable and good for running on technical trails, such as gravelly/bouldery shores and riverbeds. I hate to waste energy by focusing on not falling over, not slipping or not twisting my ankles. I find that the TerraUltra are simply superb in this regard - I'm able to relax while running.
Seen from the back you understand why the TerraUltra feels so stable - the outsole is quite a bit wider than the midsole/upper.
The TerraUltra 260g is a superb shoe for long trail runs, both training, and racing. They are comfortable, stable and provide super grip in a huge range of conditions. For the zero-drop ultra-runner, they are the ideal choice when running mixed-type trails.
Based on personal experience they will easily hold you up for a 50 miler. Be comfortable all the way and give you no trouble what-so-ever. That is after you've first broken them in properly.
If you are more of an urban runner and do not dabble particularly in ultras: I'd say the Terra Ultra 260g should not be your first choice. The TerraUltra 260g is a tool and a very good one for its intended purpose. But it is overkill if you just go for the odd mosy around the park.
Please also note that if you are not used to zero or low drop, the TerraUltra might not be for you! As always, try before you buy.
Finally, for a £140+ running shoe, I would have expected a better build quality. There should not be simple workmanship issues like the glued together gaiter attachment pockets, seems breaking and the clumsily set seams along the sides of the tongue.
This is simply not up to par - not for Inov-8, not for this otherwise super shoe. Inov-8, if you read this: Step up your quality control!
Please note that I'm an independent recreational runner. I'm not affiliated with or paid by Inov-8 for this review. I bought my TerraUltra 260g with my own money, and this review reflects my personal experience and opinion only.
The biggest difference in the G series shoes that I found is the grip of the rubber, and you can run several miles in them. There's no compromise in the durability.
When I want to go fast and short and the terrain is firm and relatively smooth the Terraultra is a blast to run. I just wish it had more heel stack and a more protective somewhat less flexible forefoot area.
- The Inov-8 TerraUltra G 260 is a trail running shoe that is specifically-made for runners who have neutral foot mechanism. It utilizes the Graphene material, an enhanced rubber that offers the right amount of traction. It is durable enough to withstand the hazardous nature of the trails.
- The upper section of the Inov-8 TerraUltra G 260 is made of a breathable mesh. This component of the footwear is meant to keep the foot cool and dry throughout the running session. Along with the breathable mesh is the Kevlar overlays. This material is used in making bulletproof vests. With the utilization of the Kevlar, the upper unit becomes more durable. It will have a longer lifespan even after running several times a week.
The Terraultra is a neutral running shoe that has a large fit. The footwear was crafted with the Inov-8’s Standard Fit last. It is sure to provide a more comfortable fit because of the shoe's rounded toe box. With the utilization of this kind of toe box, the foot is able to expand under heat. The toes will also have enough space to wiggle. The available widths for both the men's and the women's version are Medium.
