Why you'll love the K2 Cortex 140 Zonal BOA 2026 from Ski West
Engineered for peak performance, aggressive charging, and uncompromised precision, the Cortex 140 Zonal BOA® is the stiffest, most powerful boot in the Cortex lineup. Featuring an ultra-responsive 140 flex paired with the Zonal BOA® Fit System, it provides dual-dial independent adjustment across the lower shell and upper cuff. This micro-adjustable design eliminates pressure points, locks down the heel, and delivers immediate, race-like energy transfer to the ski. Complete with a fully heat-moldable shell, high-performance precision liner, and pre-installed GripWalk® soles, this boot offers expert-level power, maximum stability at high speeds, and custom-tuned comfort across demanding terrain.
