The ZoomX foam ensures maximum energy return with each stride, while the full-length Air Zoom unit adds a springy propulsion.

The modified waffle outsole improves traction on various surfaces, and high abrasion rubber enhances durability. With a ten millimeter heel to toe drop, these shoes support a natural stride to keep you moving through every mile comfortably.
