CORTEX 120 ZONAL BOA
- : In Stock
- : K2
The K2 Cortex 120 Zonal BOA is a men's low-volume alpine ski boot built for aggressive carving and on-piste performance with the most precise fit possible. Its True LV last (96-98 mm), the narrowest in K2's lineup, pairs with an innovative dual-dial Zonal BOA® closure that fully replaces traditional buckles: one dial on the upper cuff and another on the lower shell.
The bolted rear cuff Energy Bolt Spine delivers excellent rearward support and a precise forward flex, while the Dual Cuff Alignment system allows +/-2° of cuff adjustment to match each leg's anatomy. The EliteFit Sport liner, with a lace-up closure and adjustable tongue, is paired with a high-tension 45 mm Cam Strap for maximum energy transmission. The interchangeable GripWalk® ISO 23223 soles ensure compatibility with bindings using this system.

TECHNICAL INFORMATION
- Zonal BOA® Fit System - A dual-dial closure system that fully replaces traditional buckles, with one dial on the upper cuff and another on the lower shell. Allows independent, millimetric adjustment in each zone, spreading pressure more evenly than a conventional closure. The dial features a breakaway design in case of a hard impact.
- True LV Fit - A low-volume last (96-98 mm), the narrowest K2 has developed to date, with the snuggest heel and ankle in its lineup. Retains a bit of room in the forefoot and toe box for comfort on long days. Built for narrow feet seeking control and precision.
- Energy Bolt Spine - A bolted rear cuff that delivers excellent rearward support and a more precise forward flex. The top bolt can be removed for a more progressive cuff response and slower rebound. Lets skiers tune boot behavior to their own style.
- EliteFit Sport Liner - A lace-up inner liner with an adjustable velcro tongue, combining comfort and performance with a medium-volume fit and reinforced ankle pockets. Delivers a wrap-around fit without excessive pressure points. Built for intermediate-advanced skiers wanting all-day comfort.
- Dual Cuff Alignment - A dual-sided cuff alignment system with a +/-2° adjustment range. Lets skiers compensate for natural leg alignment and improve edge contact with the snow. Contributes to more efficient energy transmission on every turn.
- GripWalk® - A sole standard that replaces the classic flat profile of ski boots with a rockered shape offering more traction for walking off the snow. Improves stability and safety on asphalt, ice, or uneven ground, provided the binding is compatible with the system.
