Model [ P0371]Nike Free RN Flyknit Women's GreyNike's game changing runner steps up once again. These women's Free Run Flyknit trainers reinvent your running thanks to its lighter than light build and all-new auxetic foam outsole. Built with Nike's famed Flyknit upper wraps your foot in a sock-like, supremely breathable fit for cool performance every step of the way. Flywire cables lock your foot down, delivering adaptive support where you need it most without adding unnecesary weight, while the rounded heel delivers a more natural, comfortable footstrike. Auxetic foam to the outsole expands when stretched, meaning the pressure of every step is spread out more evenly, keeping every step comfortable, from the first minute of your sessions to the last. Keep them fresh with Crep Protect Spray (Product Code: 110853).
