K2 Cortex 120 BOA® Men’s Ski Boots 2026

The K2 Cortex 120 BOA® Men’s Ski Boots 2026 are low-volume, 120-flex all-mountain boots that pair a shell-mounted BOA® Fit System with an EliteFit Sport liner for powerful, precise performance in technical terrain.

Locked-In Fit for Aggressive All-Mountain Skiers

• Low-volume MultiFit™ last (96–98 mm): True LV shaping with K2’s MultiFit™ last delivers a snug heel and ankle with just enough room in the forefoot and toe box for all-day, performance-oriented comfort.
• BOA® Fit System shell closure: A micro-adjustable BOA® dial and steel lace wrap the lower shell evenly, boosting foothold, reducing pressure points, and letting you fine-tune fit on the fly in seconds.
• 120 flex with Energy Bolt Spine: A stout 120 flex and bolted rear spine drive power directly to the ski edge, giving you strong support when you’re charging; remove the top bolt for a slightly more progressive, forgiving rebound.
• EliteFit Sport full-lace liner: The EliteFit Sport liner blends medium-volume comfort with supportive ankle pockets, a full lace-up closure, and an adjustable tongue so you can customize heel hold and instep fit.
• Ski Edge Sensitivity shims: Tunable liner shims on the cuff let you adjust how quickly the ski rolls onto edge—more reactive for technical, slower turns or more damped and stable for high-speed charging.
• FastFIT Instep & fully heat-moldable shell: A softer TPU instep zone makes entry and exit easy, while both shell and cuff can be heat-molded for a custom wrap around your foot and lower leg.
• GripWalk® ISO 23223 outsoles: Pre-installed GripWalk® soles add traction and comfort when walking or standing without sacrificing power transfer in compatible bindings.
• 45 mm cam power strap: The wide, non-elastic cam strap locks the cuff to your leg for race-boot-style support and a precise, connected feel.

Who It’s For

The Cortex 120 BOA® is built for advanced skiers who want a narrow, performance-driven boot for freeride, big mountain, and high-speed all-mountain laps. If you like a true low-volume fit, demand strong edge hold in technical terrain, and want BOA® convenience without giving up the feel of a classic two-piece shell, this boot is aimed squarely at you.
