The boot meets the demands of both ascent and descent in mixed and technical terrain. For this purpose, the Mountain Trainer Mid GTX features a new midsole with Bilight technology. It is dual-layered for high cushioning and ergonomically shaped – providing good support in the shoe and reliable comfort even during long hikes. In the ankle area, the Flex Collar allows for increased freedom of movement backward, offering plenty of comfort during descents, even with heavy luggage. The lightweight, sturdy Vibram Wrapping Thread Combi outsole ensures a stable yet natural walking experience. The patented Salewa 3F system provides flexibility, heel support, and a blister-free fit from the very beginning.
