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 lightweight and responsiveness. Fastfit Instep: Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit. Energy Interlock: A rivet-free technology that integrates the cuff and shell, putting less stress on the boot’s lower shell and producing a smooth, progressive flex. Powerfuse Spyne: A co-injected Y-shaped support in the rear of the boot that adds strength and power to the Energy Interlock in order to maximize fore/aft flex efficiency and lateral stiffness, providing enhanced responsiveness and energy transfer to the ski. 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. 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. Friction Free Cuff Pivot: An easy-hinging cuff pivot designed to provide minimal resistance while in walk mode.
