Everyone needs a partner who will always be there, win or lose. This is the Endorphin Pro 4. Fast and responsive from the start, but both smooth and efficient. A miraculous feat that Saucony achieved by merging PWRRUN HG and PWRRUN PB foam in the midsole. The combo sits atop a carbon plate designed to add longitudinal stiffness and improve metabolic efficiency. And when you add SPEEDROLL technology, proven to propel you in a forward rolling motion, and an integrated tongue system, you get aspeed effortlessly.
