The Nike React Infinity Run Flyknit 2 continues to help keep you running. A refreshed upper uses Flywire technology that combines with Flyknit for support and breathability where you need it. The high foam heights provide soft responsiveness and long-lasting comfort. It's still one of our most-tested shoes, designed to help you feel the potential when your foot hits the pavement.
Very comfortable, but insole gets detached

I was very satisfied with my purchase, but after some runs I notices that the insole of one of the shoes got detached and now moves while running.
Excellent running shoe

The first thing I noticed when I tried on this sneaker was how comfortable and light it is. I'm a medical school student and I spend hours on my feet every day, therefore I need a shoe that feels both supportive and flexible. This sneaker is perfect for my hours spent running from patient to patient. I also wore this sneaker during my spring break, for both a hiking trip and a bike trail with my family. The sneakers were perfect for both actives. The reason I gave 4 stars instead of 5 is because the arch of the sneaker is slightly too high for me, and after hours of wear my feet were a touch sore. Otherwise this isa great shoe that I would definitely recommend.
Just the right edits to the React series for daily runners needing more foot security!

In most brands I'm a size 12, but in Nike's I'm either a 12.5 or 13. I was a 13 in Zoom Fly's but a 12.5 in Pegasus. I got the React's when they first came out and the sock-fit upper was tight in 12.5 and loose in 13. I like the simple style and the sole however so I tried again when the Infinity React's came out and the 12.5 seemed to fit. Quickly I realized the forefoot was wider and (by design for the foot to splay), but unfortunately for me, my feet don't splay that much and the shoe felt loose in the toe box. Additionally the laces were only four slots, so I could NOT tune the fit towards the toes, nor did it have that extra lace-thru by the ankle to lock my heel in. As a toe runner, that extra lace-thru does wonders to keep my foot secured to the back of the shoe and prevents the slight cramming of my toes in the front which impacts my toenails on long runs and causes pain/bleeding/fall-outs. The other differences besides more lace holes is: a padded collar, tongued-upper instead of sock fit, and less wide of a toe box. The result is a shoe that fits me much better, very similar to that of the Pegasus. A shoe thats more comfortable, more intentional, and can truly be used by the serious runner. My only gripe would be the color ways aren't that cool. I ended up getting the light grey, but would've preferred to see more relevant/unique styling.
