Features & Specs

BOA® Fit System on the Cuff and Shell

The BOA® Fit System shell 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.

The BOA® cuff single cable design allows the tension to self equalize always giving a consistent pressure to the shin. The improved wrap allows for better power transmission and improved comfort even at high tension

True LV Fit

All new low volume last featuring K2's narrowest heel and ankle while maintaining a little room in the forefoot and toe box for an all day performance fit.

Fastfit Instep

Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.

Dual Cuff Alignment

Dual sided cuff alignment for +/-2 degrees of cuff adjustment.

Energy Bolt Spine

A bolted rear cuff gives Cortex excellent rearwards support and a precise forward flex. The top bolt can be removed to allow for a more progressive cuff response and slower rebound.

Liner Featuring Ski Edge Sensitivity Shims

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.
