Go light and go fast. From muddy trailheads to rocky summits, these lightweight shoes are built to take on any fast hiking outing, thanks to the highly abrasion-resistant mesh upper and waterproof GORE-TEX Stretch membrane. A well-cushioned midsole and Ortholite Insole offer additional comfort, while a Flextron shank improves torsional stability and reduces the energy needed to move faster along the trail. The Vibram Megagrip outsole provides confident grip in wet or dry conditions. Finished with a rocker-shaped sole, the Aenergy Mtn Low GTX guarantees a smooth landing and easy toe-off so you can cover technical terrain with confidence.
