We recommend purchasing one size larger. "The best vitamin is not in a pill, it's on your feet... A stylish, super-lightweight sports trainer that will help you move more and feel great.

Biomechanically designed for exercise and everyday running, but equally good for enhancing your daily activities from fast walking to work or cycling in the city.

This FFX evolution features a redesigned cleaner-looking upper. Made from specially designed flexible knit, combining high breathability areas with extra support on the sides/arch.

There is more padding in the collar and tongue. And the new, easy-entry top line makes opening/closing easier. In our Neodynamic™ midsole: lightweight, high rebound, impact-reducing cushioning with a springy central carbon plate that propels you forward and eases heel-to-toe motion. Flexible yet firm with contoured footbeds for excellent arch support (and pressure distribution). A motivating boost for movement.

This version is made from layered, two-tone knit. The toe spring and heel strike soften movement. Internal 'flex grooves' help feet move naturally. Midsole expands at the forefoot and broadens around the trainer for balance. TPU heel clip helps stop foot roll. Reflective TPU heel detail."
