A stable, protective boot for more advanced recreational skiers. Carbon graphic highlights the precisely molded heel cap which stabilizes laterally while allowing total forward flex. Waterproof breathable Triple-F Membrane keeps out snow and moisture while letting perspiration escape. Dry, warm & breathable: The Triple-F Membrane keeps water and snow from entering boots, while allowing excess heat and moisture vapor to escape. The climate inside the boot stays warm and dry, no matter what the outside climate is. Comfort Guard for warm feet: Inside the boot, a light, thin layer of water-repellent insulation material offers additional thermal protection in the forefoot and toe area to keep the skiers warm as they glide through the snow.
