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 tread with Impact Brake System lugs for greater adaptability to hard rock surfaces.
