The boot meets the demands of both ascents and descents in mixed and technical terrain. The Mountain Trainer Mid GTX features a new midsole with Bilight technology, which is dual-layered for high cushioning and ergonomically shaped for good hold in the shoe and reliable comfort even on long hikes. The Flex Collar in the ankle area allows for increased freedom of movement backward, providing 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 offers flexibility, heel support, and a blister-free fit from the very beginning.
