Cortex 130 Zonal BOA Ski Boot - 2026

What Our Gearhead® Experts Are Saying:

"These boots rip. The dual BOA setup is next-level—it lets me lock in the fit without over-tightening, and I can make small tweaks without unbuckling. The 130 flex delivers the power I need when I’m charging steep lines or railing groomers, and the liner fit is race-tight without killing my feet."

Built for those who demand race-level power with freeride versatility, the K2 Cortex Zonal 130 BOA® boots redefine what high-performance ski boots can be. Whether we’re carving groomers at speed or navigating big-mountain lines, this boot keeps us dialed with a 130 flex and a performance-focused 96–98mm last that locks in fit without compromising comfort.

The dual BOA® Fit System wraps both shell and cuff with precision, giving us the ability to make on-the-fly adjustments while maintaining even pressure and exceptional heel hold. The EliteFit Pro liner is fully laceable with an adjustable tongue and Ski Edge Sensitivity shims that tune the boot’s edge response—so we can push faster and ski harder with confidence. The Energy Bolt spine enhances rearward support while allowing customization through removable hardware. ISO 5355 soles come installed for binding compatibility, with GripWalk outsoles included in the box for improved traction.
