The K2 Cortex 120 Zonal BOA Men Boots are a stiff, low-volume freeride and big-mountain boot for advanced skiers who want precise control and easy entry.

• Flex 120 and low volume: True LV last with a 98 mm width, a narrow heel and ankle and a little extra room in the forefoot and toe box.
• Zonal BOA® Fit System: micro-adjustable dial, strong laces and low-friction guides for a precise fit and good power transmission.
• Energy Bolt Spine: a bolted rear cuff gives rearward support and precise forward flex, and the top bolt can be removed for a more progressive response.
• EliteFit Sport liner: medium-volume fit with ankle support, full lace-up and a tongue adjustable with velcro in the toe box.
• 45 mm Cam Buckle Strap: wide strap for cuff support and a secure closure.
• Stance adjustment: Ski Edge Sensitivity (SES) shims to change the edge angle, plus ±2° cuff alignment.
• Heat-mouldable shell and cuff: fully heat-mouldable construction with a Fastfit instep in softer TPU for easier entry and exit.
• GripWalk soles: removable ISO 23223 alpine rockered soles, pre-installed, for easier walking without compromising power transmission or binding release.
