The Speed 300 IGNITE incorporates two new performance features whilst maintaining an extremely low weight. Its midsole 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. Built to perform, this neutral running and training shoe will make you feel light and fast on your feet at an 8 mm heel-to-toe drop.
