Tough and technical, the Mammut Women's Magic Advanced High GTX Boot is ready to tackle all your high alpine adventures. The abrasion resistant microfiber upper ensures durability while keeping weight down, and Gore Tex shields you from snow and water while still allowing for breathability. Base Fit 2. 0 technology improves heel support, allows better feel, and keeps blisters at bay. The memory foam footbed forms to your foot for a customized feel, and the cushy, yet responsive, PU and EVA midsole takes the sting out of your step. The ultra durable Vibram Maton outsole helps you keep your footing in treacherous terrain. Three zone lacing lets you dial in the perfect fit for your foot. This boot is also crampon compatible and rated to below freezing temps so you can take it on glacier crossings and high alpine ascents.
