Here's La Sportiva's latest single-layer lightweight boot built for precision and speed on high-altitude, alpine-style ascents. Expedition-worthy, silicone-impregnated, premium 3mm roughout leather uppers offer the finest in natural breathability and waterproof durability. Synthetic leather on cuff and boot top add strength and water resistance; sticky rubber rand stands up to rock abrasion and crampon wear. HDPE plastic midsoles provide mountaineering stiffness and stay strong in extreme cold while eliminating the weight and chill of a steel shank. Highly abrasion-resistant Flextec panels on cuff and ankle provide superb flexibility for the range of motion needed for mixed climbing use. Durable, high-traction, Vibram lug soles are step-in crampon compatible. Aluminia insulating material uses a blend of synthetic fibers and aluminum to enhance warmth by reflecting heat back towards the feet.
