Improved foam around the heel provides enhanced step in comfort, and a structural midfoot design provides a solid lock in fit. Elsewhere, Centre Path Technology helps guide your stride for a more efficient gait, perfect for over pronators. It includes a wide base platform and higher sidewalls that cradle your feet for smooth transitions and protection. The lightweight PWRRUN foam cushions each step. Above the foam, a deep sockliner of PWRRUN+ provides plush comfort.
