La Sportiva Aequilibrium LT GTX Gore-Tex Men's Mountaineering Boots, Black/Yellow

Aequilibrium LT GTX is the alpine hiking boot for heavy loads, ideal for backpacking and multi-day walks at high altitude. Exceptional walkability thanks to the innovative construction of the Double Heel™ heel: the very pronounced double-block rear geometry increases the braking effect downhill and allows a more fluid roll reducing the muscle fatigue. Durability and lightweight coexist in harmony thanks to the new outsole / midsole package with external Rubber Guard™ shell construction and internal foam material for accentuated cushioning and lightweight derived from less use of rubber layers. The shape is Ergonomic: enveloping and precise with TPU shells integrated in the toe and heel to reinforce the uppers. The 3D Flex System Evo™ directional joint with shaped malleolus and abrasion resistance, allows better control of the support and perfect mobility of the ankle. Vibram® SpringLug Tech tread with Impact Brake System lugs for greater adaptability to hard rock surfaces.
