K2 CORTEX BOA 110 2026

The K2 CORTEX BOA is a precise alpine ski boot designed to balance confident performance with lasting comfort. Its MultiFit construction distributes pressure evenly around the foot and ankle, while the supportive cuff improves stability, heel hold and power transfer to the ski.

With a 110 flex, micro-adjustable BOA® fit and a precise wrapped cuff, it delivers responsive control and accuracy through the turn. The GripWalk sole and accommodating 97–98 mm fit make it well suited to intermediate skiers who want a secure, performance-focused connection without giving up comfort.
