Medium flex meets walkable efficiency in the Atomic Hawx Ultra XTD 110 BOA GW, making this crossover boot the choice for adventurous freeride ski tourers looking to explore the whole mountain. Prolite construction starts with the lightest profile possible with reinforcement in critical zones for strong downhill performance. The BOA® Fit System uniformly wraps the shell around the foot to provide a secure foothold with bi-directional adjustments in an exceptionally comfortable low volume 98mm fit. Memory Fit gives a custom fit of shell and cuff, while a Mimic Gold Liner can be formed to the precise shape of the foot. The cuff offers 54º of natural movement, and a Free/Lock 4.5 ski-walk mechanism makes going uphill smooth and easy. The GripWalk Sole is compatible with all GripWalk, MN, MNC and Pin bindings. This is the ideal touring boot for those eager to explore beyond the boundaries.
