The La Sportiva Trango Tech GTX Mountaineering Boot confidently tackles all types of terrain. It bridges the gap between mountaineering and backpacking for travel in the mountains. A low profile midsole and sole construction allow technical footwork and edging capability when you're climbing easier graded routes while a TPU insert allows semi-automatic crampon compatibility for glacier travel. Throughout your treks, the waterproof uppers and Gore-Tex membrane keep your feet dry and comfortable on muddy trails and through shallow streams while a gusset free tongue enhances comfort during long days in the mountains. Additionally, the Trango features a 3D Flex system for precises support on rough, uneven trails and a to-the-toe lacing system that delivers a precise fit for enhanced control that's appreciated whether you're climbing a new route or traversing technical terrain.
