The Speed 1000 S IGNITE is the optimal meeting point of maximum stability and premium cushioning at a 12mm heel-to-toe drop. This running shoe is infused with four key technologies to ultimately make you faster. It is equipped with an Engineered Stability Zone in the rearfoot part of the dual-layer midsole, providing maximum support and eliminating over pronation. The midsole also features IGNITE, PUMA's superior cushioning PU foam formula that disperses impact forces while providing optimal responsiveness and energy return. An engineered forefoot Propulsion Zone in the outsole propels you forwards, generating more speed through the toe-off phase, while EverFit+ locks your foot onto the shoe's platform to secure a smooth fit and a secure ride.
