A nubuck-textile shoe developed specifically for via ferrata – lightweight, direct, close-fitting & close to the ground. With Dyneema Base Fit, fibre-reinforced Motion Control, Feet Map climate regulation, integrated memo foam, pre-shaped tongue, elastic Gore-Tex tongue construction & a small neoprene gaiter. Additional comfort & safety with the proven Gore-Tex Performance Comfort Footwear membrane & the Gripex Iron Grip sole with integrated Sonar technology, flexible ribs, special lugs & a rubber blend for increased grip on the via ferrata's iron stemples. Premium quality foam cushioning worked into the instep, shin, & around the ankles has excellent elasticity & returns to its original shape after being subject to intensive loads. Guaranteed waterproof thanks to a Gore-Tex high-fitting, sealed, insert sock. The stretch Gore-Tex tongue construction eliminates annoying creases, while the wide opening makes the shoes much easier to put on & take off. The Feet Map System addresses the very different zones of the foot: those that sweat, that feel the cold & that are pressure-sensitive. Mammut Feet Map locates cushioning, warming, cooling, slip & non-slip lining materials in all the right places. Base Fit technology delivers exceptional power transfer from the lacing section to the sole. The concept is based on free-sliding bands that are anchored to the insole. This results in enhanced safety & freedom from blisters, since the foot cannot slip around inside the boot. Mammut's patented Motion Control technology is an anatomically shaped heel cap which prevents the foot from twisting outwards by means of a reinforced interior. Handling – semi-visible or fully integrated. The unique tread construction, which is designed to ensure maximum transfer of braking & impetus force, is inspired by the concentric pattern created by sonar waves & guarantees high lateral edge stability for steep traverses.
