Details La Sportiva Trango Tech Leather GTX Mountain Hiking Boots - Men's Trango Tech Leather GTX men's boots are breathable, waterproof leather boots designed for alpine hiking: perfect for technical approach routes, glacier walking and mountain work, they are used by mountain rescue teams and alpine guides. Nubuck uppers are cut from a single piece of leather with minimal seams for improved waterproofing, together with a protective microfibre, for a long term comfort and durability. The shock absorbing, crampon-compatible midsole with protective PU-Skin reduces impact with the ground for all day comfort, while the rubber protection at the toe and heel minimises impact with rocks and roots. Like all the La Sportiva Trango series, the boot adopts the 3D-Flex System that promotes mobility and dynamic support. The tongue integrated in the uppers is made of soft, stretch fabric for maximum comfort, enhanced by the ergonomic shape and snug fit. The La Sportiva Cube sole by Vibram features a lower volume that further reduces the weight for a light and modern backpacking boot.
