The Saucony Endorphin Speed 4 blends three powerful elements in the midsole to give you that perfect feeling of propulsion and cushioning.
PWRRUN PB is a peba based foam that offers a bouncy, lightweight feel, it's harnessed by the winged nylon plate offering flexibility through the forefoot, but firmness through the vertical. Lastly Speedroll technology gives a smooth transition from landing to toe off, for a stride that feels, well perhaps not effortless, but easier.
