A favorite of hard charging habitual skiers and working ski professionals alike, the K2 Mindbender 115 Alpine Touring Ski Boots are as comfortable in the backcountry as they are in the resort (and not just on your feet) - a powerful 115 flex paired with an effective walk mode with 50˚ range of cuff motion means ripping big lines and pounding the skintrack are not only both possible, but downright pleasurable.
