PowerFuse SpYne – A 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 Interlock – A 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 Index – Dual sided cuff alignment for +/- 2˚ of cuff adjustment.

Power Wedge – The 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˚.
