K2 Men's Mindbender 130 BOA Ski Boot 2025

If your skiing takes you from resort to backcountry and back again without skipping a beat, the K2 Mindbender 130 BOA Alpine Touring Ski Boots should be on your radar. These burly hybrid boots are the pick for demanding freeriders who aren't willing to compromise on any aspect of their skiing. They pair a powerful 130 flex with BOA closure over the lower shell, which provides superior wrapping around the foot for a more comfortable and precise fit. Beyond that, the proven Mindbender fit and function are all there, so you can be confident from headwall to parking lot every day you head out.

PRODUCT DETAILS

Shell Materials
