The Lowa Men's Tibet GTX Boot is a heavy duty boot for heavy duty loads. Seriously. Load up that 80L or bigger pack and get to hoofin' it along some gnarly trails. The high cut protects the ankles against scrapes, rocks, bumps and bruises with the help of the Nubuck leather upper. Hidden within is a GORE-TEX® lining, providing the waterproof/breathable protection needed to ignore the rain and snow and continue on with the hike. The full length nylon shank adds the stability needed underfoot, even if you're adding crampons for parts of the journey. When the trail is tough, the Vibram® Masai outsole can handle it.
