K2 Anthem RX Ski Boots 2025

The K2 Anthem RX Ski Boots delivers a moderate 85 flex with traditional buckle lowers for skiers who like a familiar, no-fuss closure. A Powerfuse Spyne and Energy Interlock still put your energy right into the edges, backed by a plush LuxFit liner for comfort lap after lap. Round it out with a Gripwalk outsole and non-tapered velcro strap, and this boot is ready to handle whatever the rental fleet throws at it.

Product Details

Fit:
Last: 100 mm: Performance medium fit for people with normal width and volume feet.
FastFIT Instep: Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
Flex:
Flex: 85: A medium stiff flex for intermediate to advanced skiers.
Liner:
LuxFit Liner
Shell Materials & Design:
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.
Power Strap:
Velcro - Tapered PVC - Two Piece
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.
