K2 Cortex 140 Zonal BOA®

The BOA® Fit System works in perfect unison with the overlapping construction of the boot. The shell uniformly wraps the foot with precision, distributing pressure more evenly than buckles, improving circulation, while reducing movement. The overlap in the cuff improves contact pressure across the shin.

BOA’s uniform fit and improved pressure distribution means skiers can increase heel-hold and improve connection to the boot sole without the pain experienced with traditional buckles. This optimized fit delivers improved power transfer, stability and control during turns.

The K2 Cortex 140 Zonal BOA® alpine ski boot delivers the added benefit of superior heel hold and edge-to-edge control.
