2026 K2 Cortex 130 Zonal BOA Ski Boots

In the low-volume and dual-BOA world, the K2 Cortex 130 stands alone as a strong boot for expert skiers and pro riders looking to make their mark.

Why we like it:

With a low-volume fit, the Cortex 130 has the market somewhat cornered at the moment when it comes to low volume dual-dial boots. With a snug fit and a high flex, this boot is ideally suited for skiers who like to push the envelope in terms of speed, power, and aggression. We like the new liner, shell, and dual-dial technology when it comes to fitting a narrow foot with a high-performance boot.

Who it's for:

Strong skiers who have lower volume feet will fit the best into these boots. You have a thirst for speed and adventure and need a boot that’ll get you to where you need to be.

Highlights:

The Zonal and dual BOA closure system are the big stories here as the boot relies on a cable closure system to adjust the tightness rather than buckles. This allows for more even and round pressure along the leg and foot to feel like a custom fit for skiers. By reducing specific pressure points, the Double BOA system provides skiers with a lot of adjustment and customization with minimal effort. Thanks to the 130 flex and low-volume fit, you’ll get amazing responsiveness and precision as a result.

Things to consider:

The two main things to consider here are the BOA system and the Low volume fit. These boots are fantastic for those whom it fits, but not for those with wider feet or who are looking for a wider, four-buckle boot.
