The K2 Cortex 140 Zonal BOA is an expert-level boot that blends race precision with freeride freedom.
Zonal BOA uses two separate BOA systems for the shell and cuff, so closure can be fine-tuned zone by zone. The boot has a narrow True LV width (96/98 mm) with MultiFit, an EliteFit Pro liner with thermoformable foam and precision-mapped support zones, and a 45 mm elasticated cam power strap for dynamic power transfer. Integrated tech fittings make it compatible with both tech and alpine DIN bindings.
