Powerlite Shell – K2's highest performance shell, it is made of different thicknesses and four different types of TPU to provide the best combination of lightness and responsiveness.
Powerfuse Spyne – A Y-shaped support at the rear of the boot that adds strength and power to the Energy Interlock. This maximizes flexion efficiency and lateral stiffness to achieve better responsiveness as well as better energy transfer to the ski.
Energy Interlock – Rivet-free technology that disperses energy evenly over a larger surface area of the boot to reduce stress levels and have a more progressive flex.
Fastfit Instep – Softer TPU at the entrance of the boot to ensure easy entry and exit.
Powerfit Pro – Pre-molded liner with UltraIon heat-moldable foam. With stiffer foam and an asymmetrical tongue, this liner offers all the energy and power transmission you're looking for.
Gripwalk – Removable and interchangeable ISO 9523 alpine soles for better grip when walking.
Fully thermo-moldable
