K2 Cortex 120 Team Zonal BOA Ski Boots 2027

The Cortex Team 120 Zonal BOA gives freeriders stiff-boot response without the discomfort. Two BOA® dials and a low-volume shell create a close, custom-feeling fit, while the 120 flex drives the ski with authority.

Who it's for: advanced freeride skiers with narrower feet who want a responsive boot that stays comfortable all day.

Key features

• BOA® Fit System (Cuff and Shell) – Separate dials for foot and cuff, with a single cuff cable that evens out pressure on the shin
• TPU Shell – Smooth, progressive flex and dependable edge grip across a wide range of temperatures
• TPU Cuff – Cuff in the same TPU as the shell for a matched, connected flex
• EliteFit Pro Liner – Mapped support zones and thermoformable foam for a custom, locked-in fit
• 45MM Power Band – Wide power strap to tie the cuff to your shin
• GripWalk Outsoles – Rockered, removable soles that make walking easier and work with GripWalk bindings
• Integrated Toe Tech Fittings – Built-in toe fittings for compatibility with certain tech and alpine DIN bindings
• Low Volume MultiFit Last – Developed alongside BOA® for a close, secure hold on narrower feet
