The best Vitamin isn't in a pill, it's on your feet...a sleek superlight sports sneaker 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.
