Backcountry, inbounds, you name it, the Atomic Hawx Ultra XTD 110 Boa GW Boot has taken us there. These 110 flex boots offer comfortable flex on the uphill and easy manipulation on the downhill, and thanks to the Energy Backbone plenty of stability at high speeds. Meanwhile, the 98mm last prevents a sloppy feel, especially now that it is teamed up with a precise BOA fit system that locks our heel in place.
