The K2 Cortex 120 Zonal BOA is a men's freeride and all-mountain ski boot built for the advanced skier who wants uncompromising power and precision across the whole mountain. With a flex of 120 and a low-volume 98-millimetre last it gives a direct, reactive hold, spotted on Freeride World Tour podiums.
The boot closes with the BOA Fit System, where a micro-adjustable dial and low-friction lacing give a zonal, precise wrap without pressure points. A EliteFit Sport liner is heat-mouldable for a custom fit, and both shell and cuff can be heat-moulded for a true custom fit via the MultiFit last. The Energy Bolt Spine gives strong rearward support and a precise forward flex (the top bolt can be removed for a more progressive flex), and Ski Edge Sensitivity shims let you tune edge initiation, while Dual Cuff Alignment gives +/- 2 degrees of cuff adjustment. A 45 mm cam-buckle power strap gives maximum cuff support, a Fastfit Instep for easy entry and mounted GripWalk soles (ISO 23223) complete the setup.
