A high energy performer that rips it up all around the mountain or in the park, the BOSS 110 features an easy-fitting 103mm fit last. It utilizes similar performance technologies found in Dalbello's highly acclaimed Krypton platform, with 3-piece Cabrio architecture, Contour 4 Fit Technology, and a modern, Center Balanced 'Rocker' Stance. The high quality Instant Fit Performance liner can be thermo formed after just a few minutes of heating for an optional instant break-in. 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.
