Women’s Ski Boots K2 CORTEX 105 W ZONAL BOA

K2 Cortex Zonal 105 BOA®

The women’s ski boots K2 Cortex Zonal 105 BOA® combine precision, comfort and reliability in all conditions. Designed for female skiers who want to ski longer and faster than the rest of the group, they deliver race-boot-level performance while remaining easy to put on and comfortable all day long.

Equipped with the BOA® Fit System, they allow real-time micro-adjustment of the fit, ensuring perfect control and stability. Thanks to the MultiFit™ Last (96–98 mm), the boots adapt to different foot shapes, eliminating the need to choose from multiple width options.

The EliteFit Sport Liner provides medium volume, comfortable ankle pockets and a balance between comfort and control, making it ideal for intermediate and advanced skiers. The Fastfit Instep, made from softer TPU, makes the boots quick and easy to put on and take off.

The boots feature GripWalk soles compliant with ISO 23223, improving grip and comfort while walking without compromising the efficiency of energy transfer to the skis. The package is completed by a 45 mm cam-style strap, which increases upper-boot support and steering precision.
