With supportive cushioning built for a smooth run, the Nike InfinityRN 4 is a brand-new take on a familiar favorite. It's made from our all-new Nike ReactX foam, which gives you 13% more energy return compared with 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 to 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 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.

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?

Great looking shoe, bought 2 pair. Run small, recommend a size bigger.

Love these sneakers! You will have to size up! I normally wear a size 8 and it was tight and narrow. But, when I tried on 8.5, it was more comfortable.
Snug fit; we recommend ordering a half-size upMore Info
