Very comfortable, cramponcompatible and lightweight boot for mountaineering and trekking. Made from abrasion-resistant velours leather and Dropstop textile, the boot provides flexibility and strong lateral support thanks to Mammut® Motion Control. The cushioning Hybrid Shell provides support precisely where you need it. The patented Mammut Base Fit®technology transfers the power from the lacing area to the sole via freesliding webbing. The asymmetric lacing takes the anatomy of the foot into consideration and places morepressure on the big toes, resulting in greater precision. The waterresistant GORE-TEX® Performance Comfort Footwear Membrane, the grippy vibram® Maton sole, developed exclusively with vibram®, as well as the individually adjustable 3-zone lacing system add the finishing touches to this boot.
