The Lupo AX 120 has a 100mm last that makes the legendary fit and performance of the Krypton's Cabrio design available to more skiers by offering a wider last. This crossover Freeride/Touring boot skis equally well inside the resort or out. Tech inserts and a removable external tongue help you go up, and the legendary freeride performance of the cabrio design allows you to rip it up for the way down. Unlike overlap boots adapted for touring, where the lower shell is modified (weakened) to allow the boot to go into walk mode, with Dalbello's cabrio design the lower shell is not altered to get into touring mode. The IF AIR liner is thermo-formable for an optional instant break-in after just a few minutes of heating by the shop. Before using your new boots, you must have an authorized Dalbello retailer check your boot, binding, and sole setup. Dalbello boot soles must only be changed by an authorized retailer.
