The  Hawx Ultra XTD 110 Ski Boots set a new standard for the crossover between resort and backcountry. Among the best in the Alpine Touring category for years, the Ultra XTD has distanced itself from the pack with its now stiffer, more hard charging shell and redesigned walk mode that provides efficiency normally reserved for dedicated ski mountaineering boots. On top of that, Atomic has fitted this defiant boot with the new BOA closure for an astoundingly precise fit that we've found accommodating of many foot shapes. Can one boot really do it all? Well you won't get any closer than the Ultra XTD.
