Athlete-inspired and built for speed, this is the shoe for mountain runners looking to move faster on technical trails. The midsole’s rocker geometry drives propulsion and is made from InFuse, a light, highly responsive EVA and Polyolefin composition that provides rebound and absorbs shock. The grippy Vibram Megagrip outsole uses LITEBASE technology to shed weight without sacrificing performance, and aggressive lugs deliver a confident bite. The fit locks tight, and a knit collar seals out debris.

Customer Service Tips: This shoe is designed for a Comfort Fit, giving you the most space at the toe and a less snug fit around the foot.
