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.

Shoes are very stable and bouncy, but the insoles seem to crease/fold up while sprinting or doing A/B skips.

I was so disappointed in this show! The cushion was great. But however they were so tight in the midsection of the shoe I had to return them! It’s almost like they were elastic in the mid part under the laces. I literally had blisters on the top of my foot from them rubbing. On to the next pair I’ll try for something different.

The first five miles were very disappointing and they felt way too narrow. My feet were hurting pretty bad after the first mile. After wearing them around the house for a day or two and put another couple miles on them, they loosened up and are my go-to recovery run shoes. I would definitely go half the size up.
