Ultra-light mountain shoe for technical excursions, ideal for via ferrata, trekking, glacier crossings, and varying terrain. Excellent walking characteristics thanks to the innovative Double Heel construction: The highly pronounced geometry with a double heel design improves braking properties when descending and allows for a smoother rolling motion, protecting the muscles. Maximum durability and lightness are achieved with the new sole/midsole unit featuring an external shell construction, Rubber Guard, and internal foam for added cushioning and reduced rubber layers. The sole is equipped with a Vibram outsole with Impact Brake System lugs for better adaptation to hard rock surfaces. Soft fabric snow gaiter. Tongue with bellows construction for maximum wearing comfort. Ergonomic shape, snug and precise, with integrated TPU shells at the shoe seat and heel for shaft reinforcement. 3D Flex System Evo-Rotation with a molded ankle and protected by an abrasion-resistant TPU layer, allowing for better step control and perfect ankle mobility. Shaft made from HoneyComb Guard fabric with reinforcements from special yarn and abrasion-resistant TPU film for protection and lightness. Lacing with hooks at the top and bottom loops with an abrasion-resistant gaiter for use with crampons. Midsole compatible with semi-automatic crampons for ice or snow.
