NK Air Zoom InfinityRN 4

What's New About the NK InfinityRN 4?

This version of the NK InfinityRN 4 still provides a plush and smooth ride, with the new ReactX foam delivering more support. The revamped Flyknit upper and wider toe box help your foot feel stable and secure.

Cushioning: Super High

The more cushioning that you have underfoot, the softer and more comfortable your running experience can be. Cushioning helps soften impact as your feet hit the ground. ReactX foam gives you an incredibly smooth feeling, helping you push your limits.
