Performance is more than just a stiff flex rating. The Anthem 85 MV has the customizable features seen on K2's stiffer women’s boots, like a heat moldable Powerlite Shell and GripWalk outsoles, but with a much more accommodating fit and feel. A great balance between power and comfort for the progressing skier, the K2 Anthem 85 MV Ski Boots feature many of the same design elements of the stiffer Anthem boots in a less aggressive flex for lighter or newer skiers. The 85 Flex index, 100mm last and the pre-molded LuxFit Pro Liner makes this ski boot very comfortable. At the same time, the rear co-injected “Y” shaped design adds strength and power to the Energy Interlock, allowing the PowerFuse SpYne to maximize fore/aft flex efficiency and lateral stiffness for sustained performance and responsiveness in all terrain. The end result is a user-friendly boot that delivers all-day comfort, precision and impressive value!

Additional material and technology information

Shell materials and design
PowerLite Shell : The shell is purpose-built to result in the best skiing, lightest weight boots ever produced. Made with four different stiffness levels 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.
Last 100 mm : Performance medium fit for people with normal width and volume feet.
Flex 85 : A moderate flex for intermediate to advanced skiers.

Shell materials and design
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.
Fast Fit Entry : Softer TPU designed into the instep area of Powerlite shell for quick and easy entry and exit.
Moldable : Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.

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.

GripWalk ISO 23223 Outsoles
The GripWalk outsole system has been designed to help make your life easier and safer when walking with your ski boots on, without compromising the stability and confidence of the boot-binding connection while you ski. The slight rocker brings the walking movement closer to the natural one, while the ribbed, anti-slip material makes sure you stay on your feet at all times. The outsole piece is removable and interchangeable and it is designed to work with GripWalk binding systems for better grip and comfort.

LuxFit Pro Liner
Pre-molded and lasted with Ultralon heat moldable foams. Features an asymmetric tongue, a high density power collar and a flex notch for increased range of motion while hiking.
