Powerlite Shell – The totally new Powerlite shell is purpose-built to result in the best skiing, lightest weight boots ever produced. Made with four different stiffnesses of TPU and optimized wall thickness profiling, the Powerlite shell achieves a paradoxical balance of lightweight agility and power. The resulting boots weigh in as some of the lightest alpine boots on the market, yet they ski with all the power and drive of heavier boots.

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, putting less stress on the boot's material and produces a smoother, progressive flex.
