Designed for precision-driven performance, the K2 Cortex 120 Zonal BOA® Men's Ski Boots bring together cutting-edge BOA® technology with a responsive 120 flex to meet the demands of expert skiers. Featuring the innovative Zonal BOA® Fit System, this boot allows for independent adjustment across two zones—cuff and lower shell—so you can fine-tune your fit with micro-level control. Built on a low-volume 98mm MultiFIT shell, the Cortex 120 provides a snug, performance-oriented fit for better energy transfer and edge control. Add in the fully customizable EliteFit Pro liner, GripWalk soles, and a heat-moldable shell, and you've got a high-performance boot that’s ready to dominate the entire mountain.
