Downhill power and walking efficiency make Atomic's Hawx Ultra XTD 110 BOA GW all-mountain crossover boot the ideal choice for all-mountain skiers and freeride touring skiers looking to explore more of the mountain. The BOA® alpine adjustment system wraps the shell evenly around the foot for a close-to-the-foot fit that ensures precise ski performance while offering greater comfort. Next-generation Prolite construction starts with the lightest possible profile, then adds inserts in key areas to create an ultra-strong boot that's 25% more stable for an extremely powerful skiing experience. Thermoformable memory foam combined with the Mimic Gold liner precisely conforms to the shape of the foot. The collar offers a natural range of motion with a flex index of 54º for more relaxed walking and standing comfort. The GripWalk sole is compatible with all GripWalk, MN, MNC and pin bindings. Extremely powerful, this low-volume 98 mm shoe is ideal for those who want to explore beyond their limits.
