Liner

Intuition PowerFit Wrap BOA®– BOA liner increases adjustability and hold across the entire foot. Features stiffer foam with a full wrap design for added power and energy transmission. Completely heat moldable with pre-molded ankle pocket.

Shell Materials & Design

Shell– TPU (Thermoplastic Urethane)

Cuff– Pebax

PowerLite Shell– The 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 and freeride 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.

Power Plate

Buckles

2 Light Alloy Upper Buckles

BOA® Fit System– The BOA® Fit System provides a performance fit engineered to enhance feel and responsiveness while reducing pressure points by incrementally modulating the Alpine boot closure with precise micro-adjustments.

H+i1 DIAL– Provides micro-adjustable, precision fit and quick release, with quality and durability guaranteed. The BOA dial platform features a breakaway design engineered to eject the dial cartridge upon severe impact without damaging the system, allowing skiers to pop the dial back into the bayonet midmountain. In the unlikely event that the system is broken, it can be easily repaired and replaced.

Power Strap

Cam Booster Powerstrap

Bootboard & Footbed

Modular Honeycomb Bootboard– The honeycomb boot board includes two modular heel inserts. A soft Harsh Mellow insert for a high level of damping or a more rigid insert for improved power transfer.

Sole

GripWalk ISO 23223 Outsoles– Removable and interchangeable rockered soles designed to work with GripWalk binding systems for better grip and comfort while walking, standing, and hiking.

  Ability Level

  
  
  Advanced-ExpertWhether you charge the steepest lines, hit the biggest jumps in the park or carve with race-like precision, advanced to expert level skis, snowboards, boots and bindings are for the more aggressive rider. In skis and snowboards, you´ll often find layers of metal, carbon or other stringers for rigidity and power, while advanced to expert level boots and bindings are usually on the stiffer side of the spectrum for rebound and precision steering.
