Women's Ski Boots K2 CORTEX 85 BOA W

Women's Ski Boots K2 Cortex 85 BOA® W

K2 Cortex 85 BOA® W are women's ski boots designed for skiers developing their skills who want to move confidently both on groomed runs and off-piste. They combine a freeride character with a more forgiving flex, providing comfort, precision and control all day on the mountain. Thanks to the low-volume shell and the BOA® Fit System, they offer an excellent fit that translates into greater confidence with every turn.

At the heart of the construction is the BOA® Fit System, which enables micro-adjustment of the fit using a single dial. The system evenly wraps around the foot, eliminating pressure points and improving energy transfer to the skis. Combined with the new Low Volume MultiFit Last (96–98 mm), it provides a precise fit for different shapes of narrower feet, increasing control and riding comfort.

The shell made of TPU ensures a smooth, progressive flex and high durability across a wide range of temperatures. The cuff made of polypropylene (PP) provides stable support and predictable performance, making the boots suitable for both relaxed descents and more dynamic skiing.

The EliteFit Plus liner was designed with maximum comfort in mind. Soft foams effectively wrap around the foot, providing warmth and comfort for many hours on the mountain. Both the shell and cuff are fully heat-moldable, allowing the boots to be individually fitted to the anatomy of the foot.

Comfort is further enhanced by FastFit Instep technology, which uses a more flexible material around the instep, making the boots significantly easier to put on and take off. A 40 mm Velcro® Power Strap also provides the necessary stability by improving cuff closure and increasing precision when guiding the skis.

The boots come factory-equipped with GripWalk® outsoles, which provide better grip and more comfortable walking off the slopes while maintaining full compatibility with GripWalk bindings.

K2 Cortex 85 BOA® W are the ideal choice for skiers looking for comfortable, precise and modern boots that allow them to develop their skills in all mountain conditions.
