Scarpa has been refining the Manta Tech for nearly three decades now, and this current Manta Tech Mountaineering Boot now has Gore-Tex waterproofing to ensure proper weather protection. Not only does this Gore-Tex give waterproof protection, but also provides insulation to keep you warm in higher altitudes. Perwanger's strong suede leather encapsulates the upper for long-lasting durability, and flexible zones eases mobility while walking up and down mountains. Vibram rubber gives the sole solid traction, and it's possible to resole without affecting the boot's semi-automatic crampon compability.
