K2 Cortex 140 Team Zonal BOA Ski Boots 2027

The Cortex Team 140 Zonal BOA combines a stiff 140 flex with a freeride-tuned, low-volume shell for race-level precision. Two BOA® dials tune the foot and cuff separately, and integrated toe fittings add compatibility with certain tech bindings.

Who it's for: expert freeride and all-mountain skiers with narrower feet who want maximum precision.

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
• Fully Heat-Moldable – Shell and cuff can be heat-moulded by a bootfitter to match your foot
