The best Vitamin isn't in a pill, it's on your feet...a sleek superlight sports trainer that'll get you moving more and feeling great. Biomechanically engineered for exercise and casual running, but equally good for upping your everyday activity from speedwalking to work or cycling round town. This FFX evolution features a redesigned cleaner-look upper. In an engineered stretch knit, that combines high-breathability areas with extra support at the sides/arch. There's more padding on the collar and tongue. And a new easy-entry topline makes it simple to slip on/off. On our Neodynamic midsole: light, high-rebound, impact-reducing cushioning, with a springy central carbon plate that propels you forward and smooths out movement heel to toe. Flexible yet stable, with contoured footbeds for superb arch support (and pressure diffusion). Movement-motivating magic. This version in a layered two-tone knit.
