Mammut developed the Men's Ridge High GTX Boot specifically for grip on the iron stemples used in via ferrata climbing, but this boot excels in just about any type of hardcore backpacking. The IronGrip sole with integrated Sonar technology, flexible ribs, and special lugs give supreme traction not only on iron bars but on a wide variety of terrain. A pre shaped tongue offers comfortable and secure fit, and a Gore Tex Comfort Footwear membrane helps to keep out the elements. The lightweight Ridge High GTX offers a direct, close proximity to the ground for ultimate feel while providing the supreme support of a high cut boot. External TPU Motion Control offers reinforcement where you need it most for travelling on rugged backcountry terrain, while FeetMap climate regulation helps to keep your feet comfortable, even while you're hoofing it.
