Nike ‘Flyknit Racer’

Psyche! Been meaning to do this review for a while, but been too busy running in these shoes to find the time to write about em. But here it is, a review on my new favourite shoe, ladies and gentleman I bring you the Nike Fyknit Racer.

I had been running in adidas shoes for a while. I do still bust em out now and again. But I confess, I have recently moved brand to Nike (well for road running anyway – I also wear New Balance spikes). It was this shoe that pretty much sealed the deal. To explain why, let me offer some background. It took me a while rotating through shoe types (structured -> neutral -> racing flat) and brands (Asics -> Saucony -> New Balance -> adidas -> Nike) before I found out what I liked in a shoe; there is a footnote here actually which reads that any write up I do is a personal view as opposed to generalised profiling but if your preference is the same as mine hopefully these thoughts should serve well.

I run in ‘racing flats’ on the road. Pretty much all the time. A racing flat broadly can be categorised as a shoe designed for, well, racing. They are minimally cushioned (oxymoron?). Lightweight. Designed for a higher cadence runner, a midfoot striker, neutral gait. adidas shoes I have liked – and still like and wear from time to time – adidas Adios 2 (had three pairs and ran them in two marathons) and adidas Takumi-Sen (had two pairs and ran a half marathon in them, still my go to shoe for the occasional 5k if I can’t find my LT2’s). Things I like about these shoes are that they are flat, light and firm… they fit the profile. Then adidas introduced the Boost sole. I tried hard. I really did. It cost me, literally. 2 pairs later realised that I just didn’t get along with them. They are just too soft. I don’t get the springy thing, it’s like an additional return of energy up through your knees when you foot strike. It doesn’t feel like cushion, more like running on a trampoline. Ever tried that? Exactly. And then, shock horror, it seems that adidas started to phase out the original Adios. What’s up with that?! (See comparison of these two incarnations here). So with my old Adios 2’s on their last legs, I had to shop around for an equivalent… and I stumbled upon the Nike Flyknit Racer. I haven’t looked back.

Flyknit Racer 4

The Adios 2 reads like this in profile – 210g, 24mm in the heel, 15mm in the forefoot, a drop of 9mm and runs really firm. They encourage you to turn your stride over quickly just so you don’t have to impact for any longer than need be. Ideal. And here’s the thing. The Nike Flyknit Racer reads like this – 175g (ooo a bit lighter) and 24mm in the heel, 14mm in the forefoot so a 10mm drop. And they also run hard. Nike use the ‘Phylon’ midsole throughout the sole of the shoe which is super resilient and firm. So basically like the Adios 2!

Another reason why I prefer the FKR and why it’s my go to shoe? The Flynit. It’s amazing. It’s light, it adapts to your footshape and is, obviously, amazingly breathable. This is really important for me. When you run a marathon your feet swell. If you are wearing the Flyknit, you can start the race by lacing up tight and then the material will adapt. Not massively, you aren’t gonna ruin the shoe or gain a size just by running distance! But the upper is more elasticated than materials you find with other brands and this is a massive plus. Also the colourways are outrageous.


Nike say that the FKR is the shoe of choice for top marathoners. This isn’t quite accurate as a number of Nike pro’s are running in the Zoom Streak. See my review of the ZS5 here. Nike really pushed the original Zoom Streak and top marathoners for a long time were winning races in the ZS2 and then the ZS3. Now we are on the 5 and you see the odd pair here and there, but actually a number of top marathoners are still running in the ZS3! I would run the Zoom Streak to marathon, but actually, I find the ‘Phylon’ material in the sole of the FKR more responsive than the ‘Cushlon’ material which is a bit softer.

To summarise, the Flyknit racer is light, it has a firm sole, the drop is designed to run 5k and all the way up to marathon, the upper is inspired and they look, well, fly. I wear them when I’m not running also. Even at work to my boss’ chagrin. Go on Nike’s site and check for updates for colourways, the latest is the ‘Hyper Punch‘. I ran (and pb’d) the Berlin marathon in this shoe and pretty much run all my long runs (and a fair amount of short runs) in them. I will be wearing the ‘Pink Flash / Hyper Crimson’ incarnation at the New York Marathon in 2 weeks… If you are looking for a fast racing flat, look no further. Sorry adidas.

    Sounds and looks good. Would you be able to advise me? I’ve been running in Asics Gel Kayanos for years as I overpronate. I’m a midfoot striker who was worked hard to improve cadence to around 180 over the past year. I want to find a shoe that better supports my developing running style but don’t know where to start. Upcoming races are the Movember 10K and then Paris Marathon. Any tips?

      Hey Dude. Speak to me at RDC tomorrow. The quick answer to your question, is go for a racing flat which also offers some sort of structure in the midsole. There are several shoes like this, Saucony Fastwitch 5 is a great shoe which is light like a racing flat but has a ‘medial-post’. In Nike, the Lunaracer is a little more shoe which would offer support. If you run Asics now though and have been for some time, you’ll be familiar with their sizing – I’m sure they have a ‘paired back’ Kayano offering that would work – like the DS Racer 10. Lastly don’t discount Brooks, they are very popular with overpronators, the T7 Racer is super popular or the T5 for a little more shoe. Ultiamtely try a few pairs on and see what works! Thanks for comment. Alex

      Hi Antonio

      If I understand your comment, I would try the Flynit first. They are very similar to the Adios 2 in terms of feel. Actually in the wet the grip isn’t fantastic, this is the only downside with the shoe. I’ve never run in the Lunaracer, but my understanding is that they are a softer shoe. You might want to try the Zoom Streak 5. They perform really well in the wet.

      Good luck!

        Alex thanks to answer! I like adios2 midsole and minimally cushioned and find same shoes.
        I’ll watch ZS5 review!
        All the best for you!!

    Hey mate, I find the Nike streaks super slim fitting and the cables annoying. I usually run in uk size 9 (my actual shoe size) as I like a snug shoe but I actually found the streak more comfy in a 10. I also find the arch really high and a little uncomfortable.
    I’ve just bought the FKR in a 9.5 and can’t work out if I am also finding them slim or im just not used to the fly knit material.Would you suggest going up to a 10 or sticking with a 9.5….or even going back to my usual 9. After reading all the reviews I defo want to make the FKR my marathon shoe.

    Hello, I need some assistance. I just started running as a sophomore. I naturally have good speed but I’m working on my aerobic threshold and base. I’m a 1600-3200 runner. I’m going to start xc in the fall and mainly run 5ks. I was looking for a flat for when I can’t use spikes on some course and I was considering the fkr, takumi sen, and streak lt2. I also looked at the endorphin racer but I ruled it out. I’m a mid-forefoot striker. I’m 5’7 120lb if that helps. Any suggestions? I want a light shoe but with a solid and smooth feel.
