2027 K2 Cortex 105 Zonal BOA Women's Ski Boots

The K2 Cortex 105 Zonal BOA women’s ski boots are an awesome choice for intermediate through expert skiers who are looking for a low-volume fit with new dual-dial technology.

Why we like it:

Quite simply, there aren’t many boots out there like this Cortex 105. Built with two BOA closure systems, a low volume fit, and all the modern technologies found in ski boots, the Cortex 105 does things that most other boots just do not do. By blending a 105 flex with a 96-mm forefoot last, K2 has made a strong, high-performance boot for women who are looking for amazing performance in an all-mountain format.

Who it's for:

You are a strong and capable skier who likes a snug fit. You’re interested in what the Zonal or Dual-Dial BOA system can provide for you and you want a low-volume fit in order to get the best possible performance. You’re looking for a traditional two-piece shell that also has some modern and newschool technologies to it.

Highlights:

The double BOA is the big one here, as it allows for premium fit with minimal pressure points. The fit system allows you to fine-tune the tightness of the boot in order to achieve a perfect feel on the snow. We’re also enjoying the Fastfit instep that puts a softer TPU material over the instep to provide easier entry and exit. This accompanies a dual cuff alignment, an energy bolt spine, and GripWalk soles to round out the highlight reel.

Things to consider:

If you have a wider foot, you may feel pretty cramped in this boot, it’s definitely made for more slender-footed individuals or those who know they prefer a precise fit.
