Columbia Trans Alps II Trail Running Shoe Supremely smooth riding and armoured against rugged terrain, the men's Trans Alps II Shoes offer great protection, durability and support. Perfect for long miles in steep, uneven mountain environments, various technologies work together to deliver a smooth, stable ride of rocky ground. Seamless Mesh Upper The upper consists of a seamless construction to reduce chafing and friction when you run, which provides a soft step in feel for a sock like fit and support. No sew overlays and a mudguard offer incredible durability and protection from sharp objects you'll encounter on route. The mesh material allows air to circulate freely to the feet, improving ventilation even in warmer weather. Rubber toe and heel caps provide further protection from the rocky ground, meaning you are fully prepared for an afternoon up the mountain. Fluidfoam Midsole A full length fluidfoam midsole provides exceptional cushioning, giving you ultimate comfort and protection from the uneven, rugged ground beneath. Fluidfoam also creates great flexibility and support at all times so that you always remain stable regardless of the ground conditions to ensure the easiest possible ride. Fluidguide technology also features for enhaned mid-foot stability and a smooth ride on the trail. Rubber Outsole The full length rubber outsole offers ultimate protection and superb grip on a wide range of different trail surfaces. Trailshield also features, with a 6mm lug depth, providing complete underfoot protection from the rugged terrain to minimise the chance of injury or damage to the shoe.
