A versatile mid-width VELCRO® power strap that balances ease of adjustment with solid cuff closure. It adds extra responsiveness to boots without added bulk.
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.
BOA® boots with multi-fit last allow for a greater range of foot shapes to fit within the same shell family. Multi last boots are offered in three different volumes, low volume (Cortex) medium (Recon, Anthem and Mindbender) and high (BFC).
Adjustable rear cuff support that can be customized to fit with any calf shape.
Before using your new boots, you must have an authorized K2 Ski retailer check your boot, binding, and sole setup. K2 Ski boot soles must only be changed by an authorized retailer.
