With supportive cushioning built for a smooth run, the Nike InfinityRN 4 is a brand-new take on a familiar favourite. It's made from our all-new Nike ReactX foam, which gives you 13% more energy return compared to Nike React foam, to help you stay fresh and bouncy. (What's more? Nike ReactX reduces its carbon footprint in a pair of midsoles by at least 43% compared with Nike React foam.*) We coupled the ReactX foam with Nike Running's best-fitting Flyknit yet, so you can feel confident in every stride with soft upper support and breathability. It's the kind of shoe that supports every step in style. *The carbon footprint of ReactX is based on a cradle-to-gate assessment reviewed by PRé Sustainability B.V. and Intertek China. Other midsole components such as airbags, plates or other foam formulations were not considered.

Good to go straight out of the box and Nike are absolutely correct when they say to size up as my regular size would’ve been too small. At first they didn’t feel dissimilar to my usual winter shoe (Pegasus Trail GTX) but as I got further into my run I noticed a difference. The cushioning is plush but feels stiffer than the Pegs despite seemingly doing a better job with the wider footbed. The energy return isn’t as noticeable until later in a run when it actually does prompt you to keep going. Very happy with these nicely cushioned and very stable shoes. If I hadn’t just bought a second pair of Peg GTXs I would’ve definitely had the GTX version of these for the remainder of this winter.

Very narrow shoe. I do see that they have the wide sizing which maybe what I should've bought. I went to the store and automatically gave me the reg and I had to size up a whole size. I'm a 6.5 and had to get a 7.5... crazy! Even the 7 still felt pretty tight the 7.5 gave my feet extra room. Still concern but I really like how this shoe looks and feels so hopefully they end up working for my daily use.

Run very small. I have very narrow feet and normally wear a 7.5 or 8. Ordered an 8.5 and they were still too small. Will need to return for either a 9 or 9.5. Otherwise they feel very stable and I like the way they cup my heel. I’m not sure I love how stretchy the uppers are—I’m afraid they will lose their elasticity quickly and won’t stay supportive enough. I guess time will tell?
