LuxFit

Pre-molded and lasted with Ultralon heat-moldable foam. Features medium-density foam, premolded ankle pockets, and a medium-density collar, providing an ideal blend of performance and comfort.

40MM Velcro Strap

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.

GripWalk Outsoles

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.

Fastfit Instep

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

BOA® Fit System

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.

MultiFit™ Last

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).

Powerlite Shell

K2's highest-performance shell design, utilizing shell walls of varying thicknesses and four different types of TPU to provide the ultimate combination of light weight and responsiveness.

Powerlock Spyne

A performance-oriented walk mode designed for ski touring that offers a 50-degree range of motion. When in ski mode, Powerlock Spyne provides a powerful and secure connection for uncompromised downhill performance.

Fully Heat-Moldable

Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.
