The Dalbello KR Lupo SP ID Ski Boots are the ultimate big mountain freeride tool with backcountry capability. The boot includes Dalbello's skihike mechanism on the back of the cuff, enabling you to tour and hike outside of the resort as you please. Even with walk mode, Dalbello's Cabrio Design Architecture and 130 flex tongue, the Lupo SP is still amazingly responsive on the way down. Designed for a narrower forefoot and ankle, the Dynalink Rearfoot Retention buckle technology keeps your heel locked down securely in the boot. For extra warmth and personalization, the boot also comes with a fully thermo moldable I.D. Thermo Max Hike Liner.
