The K2 Cortex 130 BOA® Ski Boots are built for expert skiers who demand uncompromising power, precision, and responsiveness in a low-volume performance fit. Featuring an ultra-stiff 130 flex and a 96–98mm last, this boot delivers maximum energy transfer, stability, and control for aggressive all-mountain and freeride skiing.
The dual BOA® Zonal Fit System allows precise micro-adjustment across the shell, creating a fully locked-in feel with even pressure distribution and enhanced heel hold. This results in a highly responsive connection between skier and ski, especially at high speeds and in technical terrain.
Constructed with a rigid TPU shell and cuff, the Cortex 130 BOA® maintains powerful lateral support while the EliteFit Pro liner provides a performance-driven, heat-moldable fit that adapts to your foot over time.
