The Puma Faas 600 S Glow is an everyday running shoe that provides great stability & a smooth heel to toe transition for runners who require pronation support, with firm foam support, preventing you from mis-stepping through the gait transition. Its innovative Faas Foam midsole, forefoot flex & lateral release grooves, & decoupled heel are built to perform. Forefoot flex grooves align with flex notches to create a smooth heel-to-toe transition, easy toe-off, & consistent flexibility. Stability is engineered straight into the midsole, meaning no added components or weight. They achieve this through, the outsole being recessed further into the midsole, by having an increased medial midsole flare & a higher medial midsole height. All in all creating a unique stability platform, which doesnt weigh you down.
