La Sportiva Trango Tech GTX Mountaineering Boots Black/Yellow - EU 44

The La Sportiva Trango Tech GTX is a high-performance mountaineering boot designed for technical alpine climbing, via ferrata, and demanding backpacking. Combining lightweight construction with robust support, this boot features a Gore-Tex Performance Comfort lining for reliable waterproofing and breathability. The abrasion-resistant upper with ThermoTech Application™ structural reinforcements ensures durability, while the La Sportiva Cube by Vibram outsole with Impact Brake System provides exceptional traction on mixed terrain. With semi-automatic crampon compatibility (B2) and a medium-stiff flex, the Trango Tech GTX offers the perfect balance of precision and comfort for challenging ascents.
