The K2 Cortex 125 Zonal BOA® W Ski Boots are built for elite women skiers who demand maximum power, precision, and control in a high-performance alpine boot. With a powerful 125 flex and a narrow 96–98mm performance last, this boot is designed for aggressive skiing, fast lines, and uncompromising responsiveness in all-mountain conditions.
The BOA® Zonal Fit System delivers precise, even closure across the lower shell, eliminating pressure points while improving heel hold and energy transfer. Combined with K2’s Zonal Control wrap design, the boot creates a locked-in, race-inspired feel that enhances edge control and stability at high speeds.
A lightweight yet powerful TPU shell and cuff provide strong lateral support, while the EliteFit Pro liner delivers a secure, performance-driven fit that molds to your foot over time. Finished with GripWalk® compatibility and an elastic cam strap for added forward pressure, the Cortex 125 W is built for skiers who push limits every run.
