The MultiFit™ Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 97mm to 100mm out of the box (and up to 104MM* with heat molding).

Rugged, precise and intuitive. The Powerlock Spyne walk mechanism allows for 50 degree range of motion when hiking and an unforgiving, powerful connection while skiing. The mechanism can also be adjusted to customize the forward lean of the boot between 10-17°.

Removable and interchangeable ISO 9523 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.

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

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

Low friction cuff pivot to ease range of motion.

Feel locked in like never before -- the Booster Cam Strap increases performance and responsiveness by cinching tighter than a traditional power strap resulting in exceptional power transmission and precise handling.

Dial in the fit of your boot by spinning the buckle clockwise, (tighten) or counterclockwise (loosen) for the perfect fit.

All the features of the original PowerFit Pro Tour liner with the added performance and comfort of the BOA® closure system. Pre-molded and lasted with Ultralon heat-moldable foam. Featuring stiffer foam and a stiff, asymmetric tongue for added power and energy transmission, pre-molded ankle pockets, and a high-density power collar. Includes a tour notch at the back of the ankle for increased comfort and range of motion while hiking and skinning

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.
