Inspired by our athletes and designed for high speed, this shoe is ideal for mountain runners who want to increase their speed on technically demanding trails. The midsole's rocker geometry supports forward motion and is made from InFuse, a lightweight, highly responsive EVA-polyolefin mix that provides rebound and shock absorption. The grippy Vibram Megagrip outsole with LITEBASE technology is lightweight without compromising on performance. The aggressive profile ensures excellent grip. The shoe sits snugly on the foot. The knitted shoe opening protects against dirt ingress.
