This crampon-compatible alpine and trekking boot is made with abrasion-resistant velour leather and Dropstop textile. It's flexible, yet has strong lateral support due to Mammut's Motion Control technology. The cushioning hybrid shell provides support, and the company's Base Fit uses free-sliding bands to transfer the force of the lacing to the sole. Asymmetric lacing and a waterproof Gore-Tex Performance Comfort Footwear membrane round out the features. * Main product photo is Basilic/Riviera.
