Description

The K2 Cortex 105 W Zonal BOA Ski Boots set a new benchmark for performance and fit with a dual BOA design that delivers micro-adjustable precision across both cuff and shell. The all new BOA cuff is engineered to distribute pressure more consistently around the lower leg for improved flex and response, and with less fiddling to find the sweet spot. On the inside, this 105-flex ripper combines a true low-volume fit with a full-lace liner to keep your feet happy from first lap to final descent. For skiers who demand exceptional precision, response, AND comfort, the Cortex 105 is the way to go.
