Nike Epic React Flyknit: Serious runners for the casual runner
Hello, It's been a while.
I must admit, Nike and I haven't seen eye to eye for some time. Despite having purchased a couple of models very early on as a casual runner, I have not owned a pair of Nike in the last 10 years.
The only pair which I did like and kind of want, was the original Flyknit Racer when released 6 years ago. The high price tag, however, was just one of the things that got in the way.
You see, in my eyes, Nike had an image problem. With their emphasis on marketing and lifestyle, along with the controversial use of sweatshops and continued support of athletes charged with doping, it was all too easy for me to dismiss the brand in favor of those perceived more "runner-centric" such as Brooks, New Balance, and Asics.
As a runner, I wanted running shoes, not lifestyle products.
Well-publicized "stunts" such as the sub-2 hour marathon attempt didn’t help. But, beneath all that, I also knew there was also proper innovation and technology at work.
The eye-opening first encounter with the original Flyknit, the marvelous barefoot feel of the minimal Free series, and the buzz – from real runners – surrounding VaporFly 4% were all testament to that.
So here I found myself with Nike's latest "hype-able" offering in my hands – the RunRepeat in partnership with Nike.
Casual vs Serious Runner
Here is probably a good place to briefly set out my own definition of what makes a runner "casual" and another "serious," reasons for the distinction which will become clear later.
In my eyes, one is a casual runner if one runs mainly for enjoyment and for the benefits it brings to the body and soul. A casual runner "runs to eat" (i.e. cake without the guilt). A runner becomes more serious when mental and physical boundaries are pushed. A serious runner eats – discerningly - in order to run better.
A relevant observation as a running shoe geek: a casual runner will probably if they enter races at all, race in the same daily trainer that they use for everyday runs. A serious runner, on the other hand, is likely to have a set of racing flats specific to the distance being raced.
It is entirely possible for one person to be both casual and serious, depending on where they are in fitness and training. And, importantly, one is not better than the other.
My thesis is that Epic React is indeed a serious running shoe (as opposed to a lifestyle sneaker) but best suited for the casual runner.
Read on and see if you agree.
When ordering online I went for the usual US10.5 (UK9.5, EUR44.5). After placing the order, however, I saw the words on the official website; "Fits true to size for a snug fit. If you prefer a slightly bigger fit, we recommend ordering a ½ size up."
Oops. Having slightly wider feet than most, I now faced a nervous wait.
Once the shoes arrived and I pulled them on, I feared that they were indeed half size too small. The length seemed OK, as was room in the forefoot, with some wriggle room left for my toes. But the squeeze on the midfoot was crazy, to the point that I almost decided that I couldn’t possibly run in these.
And then I remembered back to that time many moons ago when I was trialing the first Flyknit and how the Nike rep had gone through the "performance" of steaming the upper and molding them to my feet.
I decided to trust the Flyknit's ability to stretch and adapt and hoped that a couple of sweaty runs would do their magic in breaking the shoes in.
Superb Design, Airy Upper
To be honest, I actually wasn’t thinking I would be running much in these, at least not yet. While Nike's formidable design team has delivered yet again, in my mind I was thinking "summer," "shorts," "casual."
True to preconceptions these looked like lifestyle sneakers designed seemingly to be walked around town in and if they performed half decently as running shoes, well, that would be a bonus.
The design strikes the right balance of subtle and contrast. I loved the College Navy colorway, what with its blue-ish white midsole, pink heel stabilizer, and yellow pull tab all coming together into something very easy on the eye.
Even the heel offset, while unusual and odd, did not detract from the overall look. A quick glance at most other Nike models suggests the flanged heel is a brand feature anyway. The offset heel is just an extreme variation on the theme.
The "tongue" is integrated into the Flyknit upper, adding to the minimal feel. Given the tightness around midfoot, however, laces almost seemed unnecessary and left there only for aesthetics. Or perhaps necessary only for those who had elected for a looser fit and sized up.
A further reason for delaying my run in these was that, with the UK still firmly in Winter's grip, it was almost too cold to be wearing such airy shoes.
The Flyknit upper, while denser midfoot and towards the midsole, were very "breathable" around the toes to the point that one can discern the color of the socks.
The React Midsole
To be sure, much of the hype surrounding the shoe was centered on React, the new proprietary high energy return midsole material for Nike. Not only high energy return, but incredibly light, and long-lasting, to boot. Time would tell with regards to the other claims, but one thing is certain right out of the box – the shoes are remarkably light.
The shoes weigh in at 239gr for size 9 and carry a 10mm offset. The stack height is considerable, at 18mm-28mm. Adidas Ultra Boost, on the other hand, is heavier at 303gr while lower profile at 12mm-22mm.
According to Nike, the React foam, which is a rubber based rather than EVA based, is more responsive and durable than their own Lunar foam, while delivering 13% more energy return. While I have no first-hand experience of the Lunar, comparison with Ultra Boost suggests the Boost is a heavier, denser material.
At any rate, as always, the proof is in the ride.
The Run Test
Winter or not, heeding to my task at hand to review the shoes in a timely manner, donning my thinnest pair of socks, I set off on a maiden 10 mile run in the Epic React.
The run was actually one of my social beer runs, involving a 6-mile jog to a designated pub, from where the group would engage in a speed session in the nearby park, returning to the pub for beers. The point is that the run would involve various paces and intensities, providing useful feedback.
I was also mindful of a half marathon coming up and unless convinced otherwise before then, Epic React would be carrying me on race day.
I was pleasantly surprised by the shoes.
"React" is an appropriate name for the midsole material, since it seemed to provide ample energy return, yet with both cushioning and responsiveness which in so many shoes are mutually exclusive. I bounced along comfortably at slower paces and powered through higher speeds.
At higher speeds, particularly when cornering, I was actually grateful for the snug fit. With a looser fit, given the stretchiness of the upper, I had visions of the midfoot spilling out over the midsole.
The shoes are notably narrow midfoot, and the relatively high stack height added to the sense of instability during tight turns.
But over this and couple of other subsequent runs, there was nothing to suggest otherwise so Epic React was my choice for the London Landmarks Half Marathon, where I had the responsibility of pacing the 1hr 45mins group.
Now, target time of 1hr 45mins is more than 10 minutes outside of my PB so I wouldn’t be going all-out, but it was still pacey enough to make it a decent morning's workout!
Pacing a race can be fairly stressful, what with having to keep an eye on your GPS watch, another on the mile markers along the route - and the two giving you wildly differing information - all the while wearing a back-pack with a large sail-like flag with target time on it so other runners can easily spot who to follow.
It is also an incredibly rewarding experience, as you get to encourage and otherwise help other runners meet their target times and indeed get over the finish line.
So, I suppose it is to Epic React's credit that the shoe was the last thing I had to think or worry about on race day, as I managed to bring runners home in 1hr 44mins 30secs!
The shoes were comfortable before, during, and after as I negotiated the streets of London and I'd add that, as racing shoes, the half marathon may be the ideal distance for Epic React, but I have no doubt they'd prove just as comfortable over a full marathon too.
The shoes were fine on wet surfaces, although not as reassuring as the Continental outsole on Adidas. But then again, in my experience, nothing surpasses Continental rubber in the wet. Ironically, the exposed midsole seemed to provide more traction on wet tarmac than the rubberized toe and heel.
I was pleasantly surprised by the Nike Epic React. While React foam is not the game changer some would have believed, it does provide excellent energy return which comes through in a cushioned and responsive ride that indeed makes running fun, particularly at slower speeds.
The shoe design, material, and production are executed to perfection and the shoe is versatile in the sense that it looks at home in both casual and race setting. The ample cushioning in the rear half also makes them great for walking in, probably the most comfortable amongst all my other running shoes, so they actually work as lifestyle shoes too.
If to be worn primarily as a lifestyle shoe, I would probably size up by half to accommodate thicker socks and since comfort rather than performance is more important. If to be used primarily for running and racing, I'd be happy to stick to the usual size to get the benefits of foot-hugging fit.
Having run in them about a dozen times, the shoes still require a bit of foot contortion to pull on but, once on, there is plenty of room in the forefoot and no discernible discomfort anywhere.
The only flaw I can think of is the narrowness of the midsole at midfoot which, combined with the stack height, takes away the stability somewhat on uneven ground and while cornering at speed.
As serious running shoes, Epic React has a place as daily and primary running shoes for serious and casual runners alike and for racing 10km up to marathon distances for the casual runner.
The ride feels consistent and smooth at all paces, but excel during the slower jogs, when one is more likely to land on the mid to rear foot. For the serious PB chasers in shorter distances, however, Epic React is no match for racing flats. But, to be fair, that isn't what the shoes were designed for.
After almost 80 miles, the sole is showing some but surprisingly little wear. As is often the case with running shoes, I reckon the outsole will out-last the uppers here.
All in all, the experience with Epic React has both reinforced my views towards Nike and shed new light.
The brand does indeed cater to both lifestyle and serious running but with Epic React succeeds in scoring on both counts thanks to great design and materials. Epic React is a serious running shoe first and foremost and that it can also be worn casually is a bonus.
I am now looking for the next pair of Nike to try. Now, that's progress!

Nike Epic React Flyknit – When the hype is hitting the roof
I had my eyes on these shoes for a while. I could see common folk just cruising the streets in them while I observed with pure admiration. Striking aesthetics with simple design and the promise of exceptional performance.
Many attractive colour options with the possibility of customizing your own on Nike’s website. Quite appealing. A clean, fresh look that allows you to enjoy them casually as a lifestyle shoe or purely for exercise. Considering the retail price, it’s a big thumbs up.
Don’t know much about it, but Nike had some serious money behind the promotion of that sneaker. I was willing to wait a bit for the dust to come down and see some of the reviews before opening my wallet, plus there was also a chance for a sale/ promotion of some kind which is always welcome. Also, they did sell out rather quickly after initial release. Patience is a virtue.
Reviews were exceptional. Experts were praising how React live up to the hype and are worth the money. Got me excited. I ventured several times to try them in shops just to make sure how I feel about the fit etc. and finally decided to purchase a pair online for $220.
Not sure why, but I got myself a white version which looked like a million bucks out of the box, but not very practical I need to admit. White didn’t stay white for long, but I wasn’t worried too much. Unboxing this piece of modern art was an exciting moment, just look at them. I think is so far best-looking sneaker I own.
I wanted to spend some quality time with them before producing a review. I managed to put on them 500km. It is worth mentioning that in the meantime I purchased another pair in light blue as I couldn’t resist $64 sale plus, I knew I will be running in NIKE REACT for a long time to come.
All my runners so far were sized US 11, and even though Nike and Saucony run bit smaller than Adidas I was quite comfortable. The upper that literally molds to the shape of your foot.
In the beginning, it is slightly difficult to slide the shoe on, but it is just a matter of time. Just need to put some time in. Not a biggie. Went one size up and now I can honestly say that it was the right choice.
Especially because my foot is a bit wide and the toe box is a bit narrow, needed some more space to feel comfortable. The website will tell you that it runs true to size, but I do recommend trying before buying, just in case.
After taking them out of the packaging straight away, I took them out for a run and I ran fast. I was super pumped. Initially, what I noticed was an unpleasant rubbing on one of the shoes in the part where tongue usually is.
I do not think that it’s an issue for the shoe in general as it was only one and it lasted several runs. Maybe some manufacturing problem or maybe one of my feet is a bit weird. Overall, I enjoyed them so much that for the past several months I used them exclusively. It is just a pleasure to run in this shoe, quite an experience.
We have here a FLYKNIT upper that will blow your mind.
As mentioned previously, it will take a moment to adjust to the shape of your foot, but after a couple of runs, it will nicely stretch to create a snug sock-like fit.
It is a one-piece structure with the tongue totally integrated. The fit is so great that it doesn’t even require tightening laces. It almost feels like your feet are naked in a good sense of that word.
On top of that, FLYKNIT upper is very breathable and flexible so your foot while in a snug hug doesn’t feel restricted. Great marriage between the strength of hold and freedom of movement. Just feels right. I loved the upper on the Ultra Boost but this is just another level.
It is very light. For stability, we have a heel shelf, which nicely keeps the back steady and secure. Just enough while not putting too much restriction while running. It is not a great stability shoe.
React midsole is nice and soft, very light and super bouncy. You could see in advertising it was compared to running on clouds or mattresses. Bottom line is, it feels great. From what I read, but also experienced in flesh, React foam shines when in motion. It basically ‘Reacts’ to the impact your foot is putting in and adequately snaps back.
When midsole compresses during a run, it quickly goes back to the original shape providing superb energy return while maintaining great cushioning. The more energy you are giving in, the more energy you are getting back. The material is designed to provide great shock absorption, so your joints will thank you for it in the future.
The look of the Epic midsole is also visually striking which contributes to the overall appeal of the shoe. The shape, the curves, the pattern. Nike Epic React has a 10mm drop.
I do prefer 8mm max myself, but it did not matter. One additional thing I noticed while running is that I would not mind a bit more extra foam on the forefoot, as sometimes I could feel a bit more terrain than I would like to.
Like the rest of the shoe, the outsole is all about keeping it light and fast. That’s why traction is strategically located only in critical places like the forefoot and heel areas to keep the weight as low as possible.
Durability has proven to be another plus of the outsole. You may initially be worried that it shows signs of wear literally right away (fifty percent of it is basically an exposed React foam), it didn’t affect the grip and overall performance.
I didn’t really test them in extreme conditions where traction would be truly challenged, but for the runs, I did it worked perfectly. Still solid, reliable and again if you just look at it you cannot help but think it does look like a piece of modern art.
The whole sneaker is a perfect blend of style and performance which make it a super versatile item. For the money you spend, you have a handsome looking shoe and a running beast. Everyone will be left with a big smile on their face.
- The overall appearance - this runner is just simply beautiful.
- Comfort and flexibility - probably the best upper I had on my foot to this day.
- Energy return - superb.
- Light weight.
- Fit - the way shoe adjust to the shape of to the foot is amazing.
- Stability - personally I don’t care, but for some may not be enough.
- 10mm drop - I would be happier with less.
- Could use some more foam at the forefoot.
- Narrow toe box needed to go a size up.
It’s hard for me to be objective here as I am in deep love with Nike Epic React. It was difficult to find faults for me in the "cons" section, but I do understand different people with different preferences will have different opinions. It’s versatile which fully justifies the price.
They are visually stunning and the technology packed into them allows you to perform at your best on your run. From all the sneakers I own, these are my favorites and probably will be for a while. I just want to see how far I can push them. Would not be surprised if I can squeeze out another 500km.
They are comfortable, light, flexible and fast plus durable. Thanks to React foam you can enjoy them for longer. This shoe ticks all the boxes. Apparently, it took an enormous amount of research and testing to develop, but I got to say, it was worth it. As a neutral runner can’t really ask for more.
I can’t wait to see what Nike will do next as in my head now this runner is hard to beat. I am very curious about the Nike Pegasus Turbo. So far I’ve read some mixed reviews. Once I admired Ultra Boost, but looking back, Nike Epic React is way more superior (especially in the weight department).
I would highly recommend this shoe to anyone who enjoys running.

Nike Epic React: Epic success or epic fail?
I knew there was a lot of fanfare around the Nike Epic React Flyknit but I really did not know too much about them when I heard I was going to get a pair to test.
Once I found out they were on their way I looked into them a bit more and could tell they were set to be something special. So when they arrived on the launch date 22nd February I could not wait to get a peek at them.
Now it is fair to say that looks wise they did not disappoint. In my opinion, they look stunning. The front of the upper is fairly plain but I Iove the sole and the back of the shoe.
The pink band around the back of the sole looks awesome and matches the other colors beautifully. This is the best looking back of a shoe I have seen and trust me, they look even better in the flesh.
All this makes perfect sense to me as the Epic Reacts feel so light and fast this the view most other runners are going to be seeing a lot of. The sole looks fantastic too.
It reminds me of a glacier, with ice blue patches over the heel and toe much like the boreholes you see on icesheets.
I was impressed before I had even put them on my feet.
How do they feel?
The Epic Reacts consist of an upper that is basically a single piece of flyknit like a low sock. There is not really a tongue as such just a tab attached to the front of the sock.
There is no padding but this is not a problem. There is not much else on top but my feet felt secure and supported.
The laces are probably the only average thing about the shoes. I’d prefer something with a bit more friction to stop them coming undone but they do the job just fine.
Given that the upper is basically a sock, you don’t need to worry about the lacing as you would in a conventional shoe so top notch laces and lacing techniques are not really needed.
When you first put them on, they feel cosseting without being too tight as you sometimes get from new sock-like shoes.
They feel light and airy and comfortable straight away. The size is just as I would expect and as with all other Nike shoes, I’d stick to my normal 10.5.
The soles are definitely chunkier than other Nike trainers I have trained. There is a hint of Hoka One-One here but they still feel light and responsive.
There's lots of cushioning and the energy return is as good as anything I have tried from Adidas.
I used to think shoes could either be cushioned so you could plod around and avoid aching feet or fast and responsive yet suffer later on.
The Epic Reacts prove that the game has changed and you can now have the best of both worlds. So far so very, very good.
No wonder they are pretty much sold out already.
What About Underneath?
I have already mentioned the ice cool design of the soles. This is not all show and no go as the pale blue parts are made of some special material that is attached to the main sole.
The material looks to be very hard wearing. If you are a heel and toe striker these should last for ages.
You could question why the whole sole is not covered in the blue material for increased longevity but at the moment that is a small gripe.
Grip is fine. The soles don’t look like they are going to provide excellent traction but so far I have had no problems on damp pavements.
The soles feel a lot wider than the uppers which I like.
Even though these are not really support shoes, they gave me confidence that I was not going to go over on my ankle if the surface was less than perfect or when taking tight turns. This may all be psychological but it was a feeling I appreciated.
The Epic Reacts are fast and comfortable. They feel light and springy and encourage a high cadence throughout your run.
I would be happy to use these for any road runs from 5k to a half marathon though I have only done a few short runs so far.
The soles feel soft without being spongy, giving you enough feedback to savor every step. A hard balance to get right but Nike seems to have managed it.
First impressions suggest Nike have made a do it all running shoe.
No doubt in my mind, the Nike Epic React Flyknit looks amazing, especially from the back. They are genuinely different to anything I have ever owned and people notice them.
I know it should be all about comfort and performance but why can’t we have form and function now and again? Their performance more than matches their appearance. They feel fast.
The kind of shoe that you take out on a route you have covered hundreds of times and by the end of the run, checking your watch provides a pleasant surprise. It didn’t feel super fast but it was.
The new foam in the sole is a revelation. The cushioning is superb and even over long runs, there were no aches in my feet or a feeling of heavy legs.
I have had a couple of pairs of Nike Lunar Epics which I am a big fan but the Epic Reacts are a massive step forward. My only wish is for Nike to launch a Shield version so I can wear them all year around.

Nike Epic React Flyknit: Running on clouds?
I bought the Nike Epic React Flyknit due to its strong advertisement over cushioning and responsiveness all together in a lightweight shoe. So after a couple of months let`s review it!
I usually go for darker colors so once again I got the blackest one but there are other more colored ones like orange, grey, and green.
Even though it’s a “high tech” shoe, I think it missed some more sleek details to balance out its dark black design. For the first time, I had a Nike shoe that I almost cannot see the Nike logo, and I still cannot say if it`s good or not.
Advertised to be a seamless shoe, comfort should be a plus here, and that actually got it done! You wear it like a sock without feeling anything bothering your feet at all. (A little different from Adidas Ultra Boost for instance - see my review here.)
My only warning here is that you are probably going to prefer this shoe 1 size bigger than your standard size.
For the upper, Flyknit technology reinforces the protection of the toebox all the way to the edges of the shoe. It offers good breathability and in terms of durability, it’s also proven to work.
And in case you are wondering, yes, I wore it without shoelaces, they are simply useless with this kind of shoe.
Nike advertised that their “React” foam is the best of the market, with better responsiveness when compared to “Lunar” foam by 13%, as well as lighter and softer altogether.
And yes, they did it again. Lightweight and responsiveness is a major plus here. I managed to actually increase my average running speed for around 10%.
Look how thick the midsole is, almost as big as the shoe itself, and lightweight at the same time – see Weight section right below.
The only remark is that when you actually wear the shoe, you can feel it’s different from a standard cushion you may be used to, and it is, it`s a Nike exclusive technology. Therefore, you may need a couple of runs to get used to it. Also because of its higher midsole, you will also need to be more careful regarding stability, which we will talk more about it later on.
To conclude, I would say that “React” really provides a groundbreaking cushion scheme here, a big plus for Nike.
I cannot believe how light this shoe is!
Despite its cushion, Nike managed to build a solid well-constructed and responsive lightweight shoe.
I would say it’s the best cushion-weight balance out there. Another big plus for Nike here.
As similar to Adidas Ultraboost, Nike had to reduce the ankle support in order to provide a “sock feeling”, as a result, stability was compromised.
The only stability is a thin easily folded layer of material, and together with a high midsole, enhances the possibility of a twisted ankle.
For that, I give a big minus since as its already a very lightweight shoe, Nike could have done better here without compromising its overall weight.
Generally speaking, Nike shoes are mainly asphalt shoes with rubber soles, but in this case, I felt they went one step further.
As you can see from the pics below, there is an additional pneumatic layer of sole both in the front and back of the sole, providing a very good grip, not just on traditional asphalt and running paths but also trails and wet surfaces.
Another plus here. My only remark is regarding the durability of this sole since it is very thin.
I`ll get back with you, later on, to talk about that.
Something else I always like to have on my shoe is an additional safety for night running, and Epic React also has that reflective light on the back.
The day after
A very important part for me is the impact of exercise on the day after. And with Epic React the results were not straightforward.
At first, I experienced knee and muscles sore on the side of the leg, which had me worried. After a couple of runs though, the sore reduced to none, so I probably just needed to get used to the different cushion technology and low level of stability. After a while, I had not noticed shoe specific sore, just regular muscle tiredness.
Nike Epic React Flyknit is a long name shoe and they should improve that. Constructively speaking, it is comfortable, is amazingly lightweight cushioned shoe, has good ventilation and is made of high-quality material. I could go one step further and maybe say that Nike almost got it 100% right, missing basically on a more beautiful design and better stability.
During first exercises, you may need to get used to its new React cushion technology, but after a while, you feel its great responsiveness even though its lightweight, the best of both worlds.
Even though Nike did not provide good stability here, you can take care and bear with it since it worth the advantage of great responsiveness resulting in higher running speed. My tip here is to train with a heavier shoe with better stability and once in a while wear Epic React for performance training.
Epic React has few minuses (design/stability) but strong positive points, therefore I totally recommend it.
Updates to Nike Epic React Flyknit
- Nike introduces a new foam technology, called the React, in the Nike Epic React Flyknit. This running shoe claims to provide a whole new level of comfort that is long-lasting. Its durable, flexible, and responsive properties make it ideal for road running, casual jogging, and speedwork on the track.
- Unlike other midsole foams made of ethylene-vinyl acetate (EVA), React is made of a unique rubber that is proprietary to Nike. This material is present in both the midsole and outsole to keep the shoe’s weight at a minimum, but not at the expense of performance.
- The shoe’s upper is a soft and secure Flyknit material, to give the foot a secure wear that feels as comfortable as a sock. The design maintains simplicity, in order to promote optimal breathability. With a lightweight and seamless construction, the upper offers a precise fit that improves the running experience.
Nike Epic React Flyknit size and fit
The Nike Epic React Flyknit has a standard running shoe length, and it will fit wearers with a narrow to moderate foot volume. The forefoot and midfoot construction allows a snug fit; thus, runners who prefer to have more room might want to purchase a half-size larger than usual. This shoe is available in medium width for both the men’s and women’s versions.
The React foam outsole of the Epic React Flyknit aids the midsole in providing a sufficient amount of energy return, as well as additional cushioning for the underfoot. Because it is a foam material, this outsole resists compression and is able to retain its shape, appearance, and structure even after many miles.
There are sticky rubber reinforcements strategically placed in the forefoot and heel areas. This is to give the outsole durability and the needed traction to grip various surfaces, especially roads.
The midsole also uses React foam. In a nutshell, the development of this technology was the result of runners’ clamor for a shoe that offers the following: increased cushioning to protect from impact, prolonged energy return to handle long runs, lightweight underfoot protection, and durability.
The React foam claims to be exceptionally responsive and bouncy. It responds by “snapping back” as a reply to the foot’s impact during landing. Compared to Nike’s other proprietary cushioning, the Lunarlon, the React foam has 13% more energy return. This midsole foam is used in the Epic React Flyknit 2 and other well-known Nike road running shoes.
Nike also introduces Fluid Geometry, a technology that works by altering the design of the midsole – it extends to the upper and around the heel to enable stability. With Fluid Geometry, the shoe is made lightweight as the midsole is distributed across the entire shoe. However, the minimal weight does not hinder the shoe from supplying adequate support and responsiveness. Therefore, this feature is present to maximize the runner’s performance.
There is an injected heel clip made of thermoplastic urethane (TPU) that equips the shoe with added stability, especially during transitions.
The upper’s internal structure is a Flyknit bootie, which consists of a single-piece element, precisely engineered for support and flexibility. With such a construction, the upper is minimal and breathable. It also delivers a sock-like fit, thus ensuring a locked-down feel and a secure run.
Because of the bootie construction, the tongue is seamlessly merged with the rest of the upper. Thus, there is no pressure on top of the foot, in contrast to other running shoes with traditional tongues.
For an even snugger fit, the heel area has Heel Skin, a thin and pliable structure that supports the heel minus the hard and irritating sensation.
