Men's Endorphin Pro 4

The Endorphin Pro 4 running shoe is a miraculous engineering feat: snappy, responsive, smooth, and efficient. We achieved this by fusing PWRRUN PB and PWRRUN HG in the midsole—an industry first. A full carbon plate adds longitudinal stiffness and maximum metabolic efficiency. The silky-smooth heel liner and integrated tongue system make this marathon shoe feel like slipping on an old friend on race day.
