Men’s K2 Cortex 110 BOA® Ski Boots

A new definition of mountain enjoyment. The Cortex 110 BOA® model offers an exceptional balance of control and comfort – ideal for skiers who expect high performance without unnecessary stiffness.

Why choose them?

The K2 Cortex 110 BOA® ski boots were designed to provide comfort and a precise fit. With the BOA® Fit System, you can quickly and accurately adjust the boot to your foot with a single turn of the dial, eliminating pressure points and gaining improved responsiveness. The MultiFIT Last (96–98 mm) provides an excellent fit for a narrower foot profile while offering comfort during all-day skiing. Putting the boots on and taking them off is made easier by the FastFIT Instep, a flexible TPU panel in the instep area.

You can fine-tune the fit even further with Dual Cuff Alignment and the Adjustable Rear Cuff Spoiler, which allow lateral and rear cuff adjustment. Stability and a secure fit while skiing are ensured by the Energy Bolt Spine (TPU), which reinforces the rear part of the boot. The EliteFit Plus Liner provides comfort and allows for full lacing to adjust the boot to your personal preferences.

When walking around the slopes, you will appreciate the GripWalk Outsoles (ISO 23223) – replaceable soles with a tread that improve grip and comfort. The package is completed by a wide Power Strap (Velcro), which stabilizes the upper part of the boot, while the H+i1 BOA Dial system with two buckles allows for an even more precise closure and micro-adjustment. With a flex rating of 110, this model is an excellent choice for intermediate and advanced skiers looking for a versatile and reliable boot for a variety of conditions.
