Impact-resistant, durable, and performance-driven, the H4 BOA® Dial ejects on severe impact and is easily re-inserted into the boot. One dial controls the upper shell lacing, and the other maintains the lower shell lacing.

Proprietary liner lacing system that harnesses the power of BOA® to provide superior heel hold and support.

A liner designed for comfort and warmth, from start to finish. It features reflective heat blanket panels that work to trap heat in and keep cold out. These reflective heat blankets work alongside heat moldable Intuition® foam, internal J-Bars, and 3D molded, dual- density EVA insoles to keep your foot comfortable and warm all day long.

The flex zone upper is designed to help retain a consistent flex pattern while reducing shell distortion when flexing.

A K2 Snowboarding exclusive, Endo™ Construction, allows us to alter a snowboard boot's flex, response, and rebound without adding extra materials (extra materials = excess weight). By replacing additional materials with an injected heel counter, adding an extra rebound is as easy as a formula change. In addition, it helps us to provide a more consistent flexing, longer-lasting snowboard boot.

Harshmellow™ is a magical dampening system that replaces industry-standard foam dampening materials. Harshmellow™ is strategically placed to dampen vibration underfoot to provide a more “quiet” feel underfoot, reduce vibration from impact, and reduce fatigue while snowboarding.

Dual-density EVA foam provides contouring cushioning and support to support snowboarding all day long.
