evo.com | K2 Alpine Ski Boots > As freeride speeds creep up into alpine racing range, the old racer's adage that "weight is great" in your boots starts to make sense off the racecourse. A prime example of that is the new K2 Cortex Team Zonal BOA 120 Ski Boots, which set the bar for rock solid stability at the limit. Thick and heavy TPU shells and cuffs deliver every once of power you've built up over the years and dampen the ride when the going gets gnarly, while the Zonal dual BOA(R) system gives you supreme comfort and untimate adjustability on the fly. Cuff TPU (Thermoplastic Urethane) Flex: 120 A stiff flex for advanced to expert skiers. GripWalk ISO 23223 Outsoles Removable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking. Non-Elastic Cam Strap - One Piece BOA(R) Fit System The BOA(R) Fit System provides a performance fit engineered to enhance feel and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise micro-adjustments. | K2 Cortex Team Zonal BOA 120 Ski Boots 2027 - 27.5 | Plastic
