Altra W Lone Peak - Inspired by Lone Peak, one of the rockiest, toughest mountains on the Wasatch Range, The Altra Lone Peak trail running shoe was designed to conquer the Wasatch 100 trail run. While the foot-shaped design allows athletes to stay relaxed and comfortable for hours, this do-everything mountain shoe promotes happy feet, increases ankle stabilization, and improves form with the Zero Drop™ platform. Quick dry, abrasion resistant mesh upper with minimal seams and asymmetrical lacing. Innovative, sandwiched StoneGuard™ system deflects rocks into the midsole for a smoother, more stable ride. Drilex premium liner, Natural Ride System (NRS), and TrailClaw outsole. Wt. 8.9 oz.
