La Sportiva Trango Tech GTX mountaineering boots bridge the gap between hiking and mountaineering , offering an option which helps us confidently overcome all types of terrain. We appreciate it that their low-profile outsole and midsole provide technical footwork and climbing ability on easier routes and also provide compatibility with semi-automatic glacier crampons. Waterproof upper and GORE-TEX membrane keep feet dry in mountainous terrain , and the gussetless tongue design improves comfort for miles on the road.
