K2 Cortex 140 Zonal BOA® Men's Ski Boots 2026

Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.

The BOA® Fit System delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.

Ski Edge Sensitivity allow the skier to tune edge initiation of the ski.
SES Shims on Medial side of liner Cuff produce more inside edge angle. Skis feel more reactive and quicker to edge, excellent for slower more precise skiing.
SES Shims on the Lateral side of liner Cuff produce less inside edge angle. Skis feel more controlled and more stable, excellent for higher speeds.
