TRUST A PROFESSIONAL:

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.

PrecisionFit Pro Tour:

Laceable, Pre Molded and Lasted with Ultralon heat moldable foams. Features an asymmetric tongue, a high-density power collar and a flex notch for increased range of motion while hiking.

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.

Integrated Tech Fittings:

Tech fittings in the toe and heel are fully integrated into the shell injection, allowing for compatibility with both tech bindings and alpine DIN bindings.

MultiFit™ Last:

The MultiFit Last was developed in conjunction with the BOA®

Fit System to accommodate a variety of foot shapes ranging

from 96mm to 104mm, eliminating the need for multiple last

options.

* Mindbender, Anthem, & Recon BOA® models range 97mm - 100mm

* Cortex BOA® models range 96-98mm
* BFC BOA® models range 100mm - 103mm (104mm with heat molding)

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.

Modular Honeycomb Boot Board with Hard & Soft Inserts.:

Stay Warmer, Longer. Traps heat and insulates like a down jacket. Retains heat 15% better than traditional boot board. Boot-fitter friendly.
