Women's Nike Free RN Flyknit 2018 Running Shoes Black / Black

Wherever you run, whenever you run, however you run — run free with the barely there feel of the Nike Free Flyknit 2018. To make the shoe feel like an extension of your foot, Nike began with a seamless Flyknit upper that supports without restricting, moving with you as you run. Next, a light yet durable foam unit doubles as both midsole and outsole, keeping the shoe's overall weight at a minimum without sacrificing underfoot protection. Deep flex grooves are cut into the foam, creating an auxetic tri-star pattern that expands and opens at heelstrike, following the natural movement of your foot while evenly dispersing the forces of impact. At toe-off, this flex pattern contracts, allowing energy to return tour next stride. The result? A shoe that allows you to run as nature intended while still delivering the underfoot protection and durability you need to push farther and faster. The Nike Free RN Flyknit 2018 looks great, too, so you can feel confident from the moment you lace 'em up.
