Trek through treacherous terrain with the Salewa Men's Mountain Trainer Hiking Shoe underfoot. Its 3F System Evo uses aluminum stays at the heel for flexibility and mobility that won't interfere with the shoe's much needed support. Salewa made the Mountain Trainer's upper out of Cordura for breathability, reinforced it with suede for durability, and gave it a 360 degree rubber rand for rock protection. The breathable lining features Cleansport NXT's odor resistant treatment for long lasting freshness. Climbing style laces secure the shoe's fit from heel to toe. This shoe also features a conforming Multi Fit Footbed for customized cush, a mid stiff nylon midsole for stability, and Vibram's rugged Alpine Approach sole for supreme grip.
