Unifying rugged materials, lightweight construction, plush comfort, and precision performance, La Sportiva built an unstoppable force, the Aequilibrium LT GTX Mountaineering Boot. The max cushiness underfoot propels us onward while the moisture-wicking, waterproof lining keeps our feet comfortably dry throughout the ride. When we approach the ice wall, we pull on our semi-automatic crampons and start the ascent with the mesh-flanked shaft allowing increased ankle mobility. Customer feedback suggests this shoe runs small, we would suggest sizing up if you are unused to a tight performance fit.
