Its breathable upper helps your feet feel contained but flexible while increased cushioning around the heel and ankle provides a supportive sensation. A unique rocker-shaped sole allows for a smooth, stable ride on long and short routes. Secure, Breathable Flex Flyknit throughout the upper creates specific zones of breathability, flexibility and containment for a feel that is cool and secure without being restrictive.
