The Lupo Factory combines category-leading climbing capability with the ultimate freeskiing performance on the ride down. Utilizing the popular Krypton architecture, this boot comes with tech inserts, a full carbon cuff, and a removeable Kinetic Response Tongue that goes on and off in an instant. With the tongue removed and the boot in hike mode, the skier enjoys a full 67 degree range of motion for a long stride while climbing. Thanks to the carbon cuff and the Grillamid Green material in the lower shell, the weight is just 1625 grams per boot with the tongue removed. Unlike the many traditional overlap boots in its category, the Lupo's Cabrio 3 Piece design does not require any modification of the lower shell to enable a hike mode, so the skier enjoys legendary freeride performance with the boot returned to ski mode for the descent. The ID Max Hike liner is thermo-moldable for the ultimate custom fit, and like all ID liners offers light weight and optimal warmth. Now available: GripWalk® soles with Vibram®!
