Its low profile sole and midsole allow technical footwork and edging capability when climbing easier graded routes, while also offering semi-automatic crampon compatibility for glacier travel. The leather upper and GORE-TEX membrane keep your feet dry and protected across mountainous terrain, and the gusset free tongue construction increases comfort for long miles on the trail. Additionally, the Trango features a 3D Flex system that promotes precise support on rough terrain and a to-the-toe lacing system that delivers a precise fit for enhanced control. The latter's appreciated always, whether you're climbing a new route or traversing technical terrain.
