The Mammut Kento Mountain High GTX are mild-weather mountaineering boots loaded with all the features to keep us going in the mountains. The fully waterproof and breathable PU membrane ensures the moisture stays out, and the GORE-TEX tongue gusset and lining give us an extra layer of protection. These boots are compatible with automatic crampons, have 3D memory foam cushioning for comfort and support, and have a TPU heel stabilizer and toe cap for protection and support.
