Shell Materials & Design

PowerFuse SpYneA rear co-injected “Y” shaped design that adds strength and power to the Energy Interlock, the PowerFuse SpYne maximizes fore/aft flex efficiency and lateral stiffness for sustained performance and responsiveness in all terrain. Because of the SpYne, K2 is able to optimize materials in the cuff and shell, eliminating excessive vibrations in rough terrain.

Energy InterlockA rivet-free technology that integrates the cuff and shell of the boot. The Interlock stretches when the boot is flexed forward, and the energy is released throughout the turn, creating a smoother, more natural flex than riveted designs.


Cuff Alignment IndexDual sided cuff alignment for +/- 2˚ of cuff adjustment.

Power WedgeThe Power Wedge is a removable spoiler for accommodating varying calf shapes and adjusting your desired forward lean angle. The Power Wedge increases forward lean from 12˚ to 14˚.

Power Strap

40mm Velcro Powerstrap


GripWalk® Outsoles Available SeparatelyNew removable and interchangeable ISO 9523 alpine rockered soles for selected K2 boots collaberatively 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.
