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. Women's-Specific Last: A lower cuff height, lower-volume shell, and narrower heel to accommodate women's lower leg and foot shapes. Women's-Adjustable Cuff: Allows for quick adjustment of the cuff opening to accommodate a variety of lower leg shapes.
