When you're hiking hours under your own headlamp so you can see the summit at sunrise, it's a smart idea to fool your foot into thinking it's still tucked in bed, and the Mammut Women's Ayako High GTX Backpacking Boot is up to the task. Mammut's Motion Control technology includes a triple-density midsole for the support, stability, and cushioning required for the mountain's toughest trails. The boot's strong velours leather upper features a Gore-Tex Performance Comfort lining for reliable waterproofing and enhanced breathability to maintain comfort during active endeavors in inclement weather. A Vibram sole comes with a mountaineering-specific Mulaz tread for reliable traction on dirty trailheads and rocky summits.
