2026 K2 Anthem 85 BOA – Women’s Boot

MultiFIT Last: 97 – 100mm – The MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes ranging from 97mm to 100mm eliminating the need for multiple last option (LV, MV).

FastFIT Instep – Softer TPU material is used in the instep area of select models’ shells for quick and easy entry and exit.

Flex: 85 – A medium stiff flex for intermediate to advanced skiers.

Luxfit Liner

Shell – TPU (Thermoplastic Urethane)

Cuff – PP (Polypropylene)

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.

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.

Fully Heat Moldable – Both the boot’s shell and cuff are capable of being heat molded to a variety of foot shapes for a truly custom fit.

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.

Velcro – Tapered PVC – Two Piece

Modular Honeycomb Bootboard with Soft & Hard Inserts – 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.

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.
