Aequilibrium LT GTX is the mountain boot for alpine excursions with heavy loads, good for backpacking and multi-day alpine tours. Good walking characteristics thanks to the innovative Double Heel construction: The distinctive geometry with double heel construction improves the braking characteristics when walking downhill and enables a smoother rolling behaviour so that the muscles are spared. Durability and lightness harmonise well thanks to the new sole/midsole unit with external Rubber Guard shell construction and internal foam for more cushioning and lightness thanks to fewer layers of rubber. The shape is ergonomic: enveloping and precise, with integrated TPU shells at the toe and heel to reinforce the upper. The 3D Flex System Evo-Rotation with moulded ankle and abrasion-resistant protection enables better step control and good ankle mobility. The midsole is compatible with semi-automatic crampons and the Vibram SpringLug Tech outsole with Impact Brake System lugs ensures better adaptation to hard rock surfaces.
