La Sportiva Aequilibrium LT GTX is a mountaineering boot, ideal for your adventures in the high mountains and for multi-day walks at high altitude. The leather upper with Gore-Tex membrane is waterproof, breathable and adapts to the foot and movements, making it really comfortable. In the ankle area there is the 3D Flex System Evo directional joint with shaped malleolus that guarantees you incredible protection, control and mobility. Part of the upper is covered with a TPU shell called Rubber Guard which improves the resistance of the boot and foot protection. The midsole made of foam material exceptionally absorbs the roughness of the ground, remaining light and not weighing down the boot. The innovative Double Heel construction also contributes to improving walking, which with a double rear gusset geometry increases the braking effect on descents and allows for a smoother roll, reducing muscle fatigue. The Vibram SpringLug Tech tread with Impact Brake System lugs allows excellent adaptability to hard rock surfaces and guarantees all the grip you may need in any situation and terrain.
