The K2 Anthem 85 BOA Women’s Ski Boots make progression easier with a forgiving flex, precise BOA adjustment, and a fit designed specifically around women’s feet. The approachable 85 flex gives beginner to intermediate skiers the support to start carving harder and exploring more of the mountain without feeling overly stiff or demanding. K2’s TrueForm Last improves heel retention and creates a more natural anatomical fit, while TrueAlign Geometry optimizes stance and lower-leg positioning for more efficient skiing. The BOA Fit System provides quick, micro-adjustable tension across the lower shell, and the 97–100mm Mid Volume MultiFit Last accommodates a range of foot shapes. A heat-moldable shell and cuff offer additional customization, while the soft FastFit Instep makes getting in and out easier. Finished with a comfortable P4 liner and GripWalk soles, the Anthem 85 BOA is a comfortable, responsive women’s all-mountain ski boot built for skiers ready to keep progressing run after run.

TrueForm Last

Women's feet aren't simply scaled-down men's feet. TrueForm Last was developed specifically around female foot anatomy to deliver stronger heel retention, improved comfort, and a more natural fit from the moment the boot goes on.

TrueAlign Geometry

When your stance is balanced, skiing becomes easier and more efficient. TrueAlign Geometry adjusts ramp angle, forward lean, cuff alignment, and lower-leg interface to better match female biomechanics, helping skiers stay naturally centered and confident on snow.

BOA® Fit System

The BOA® Fit System delivers dialed-in performance and a micro-adjustable precision fit, engineered and guaranteed to perform in demanding conditions. It consists of a micro-adjustable dial, lightweight yet extremely strong laces, and low-friction lace guides applied in a configuration designed to improve the fit and performance of the boot.

Mid Volume MultiFit Last

The MultiFit Last was developed in conjunction with the BOA® Fit System to accommodate a variety of foot shapes and ensure a better, more secure fit. The Mid Volume MultiFit Last is ideal for boot widths from 97–100mm.

Fully Heat-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.

FastFit Instep

Softer TPU material is used in the instep area of the shell for quick and easy entry and exit.

TPU Shell

TPU is the benchmark material for alpine ski boots, delivering a smooth, progressive flex with outstanding durability and dependable performance across a broad range of temperatures. Its balanced feel provides predictable power transfer, strong edge control, and all-day confidence, making it an ideal choice for skiers who value precision without sacrificing comfort.

PP Cuff

Lightweight and durable, the polypropylene cuff delivers consistent flex and reliable support in all conditions. Engineered for comfort and performance, it provides control without unnecessary weight.

P4 Liner

The heat-moldable P4 liner combines a PVC outer material, PE mid foam, and an open-cell inner for soft, forgiving cushioning. A supportive 10mm PE tongue adds structure without unnecessary bulk.

30mm Velcro Strap

Slim and simple, the 30mm VELCRO® power strap is lightweight and user-friendly, offering secure cuff closure for recreational skiing with comfort and convenience as top priorities.

GripWalk Outsoles

Preinstalled removable and interchangeable ISO 23223 GripWalk soles feature a rockered profile designed to provide better grip and added comfort while walking and standing in ski boots without compromising power transmission and release performance with compatible bindings.
