Mammut Mt. Cascade GTX Backpacking Boot - Men's description: Mammut made the lightweight Mt. Cascade GTX Backpacking Boot using rugged Dropstop textile and velour leather reinforcements which increase durability for demanding backcountry tours. This boot’s asymmetric lacing adapts to the anatomy of your foot and boosts pressure on the big toe, making precision footwork easier in a larger boot like this. A Mammut® SD footbed provides the comfort your feet desire, and Mammut’s Base Fit® technology prevents your foot from sliding around inside the boot, lessening the chance of blisters and rolled ankles. Grip is provided by a grippy Vibram® rubber outsole with aggressive lugs. These boots are also strap-on crampon compatible and fully waterproof- breathable thanks to a Gore-Tex® membrane.
