Your heel to toe transition needs more. And by more, we mean less. The Faas 500 is a minimal neutral trainer with an optimized amount of FaasFoam cushioning and underfoot protection for everyday training. This updated version introduces a brand new upper with upgraded materials and a minimal EverFit system that locks the midfoot in place. The Faas 500 also has a decoupled heel crash pad, lateral release grooves, and flex grooves for a smoother heel to toe transition.
