The Puma Women's Faas 600 S is an everyday running shoe that provides great stability and a smooth heel to toe transition for those who require firm foam pronation support that prevents the heel from rolling inwards during the gait transition. An innovative FaasFoam midsole, forefoot flex/lateral release grooves and decoupled heel are built to perform. Forefoot flex grooves align with flex notches to create a smooth heel-to-toe transition, easy toe-off, and consistent flexibility. Stability is engineered straight into the midsole by increasing the medial midsole height and flare - the absence of additional components reduces the number of potential fail points and overall weight.
