K2 Men's Boundary Snowboard Boots 2025

Flex Rating – 6 (1 Soft - 10 Stiff)

Articulating Cuff Upper with HDR Premium Synthetics

Intuition™ Control Foam 3D Liner – Built with a blend of high and medium density Intuition® foam, this is our most versatile liner. With internal and external J-Bars and a 3D molded EVA insole, the Control Foam 3D liner is built to provide all-day comfort and support.

3-Point Harness Liner Lacing System – The 3-Point Harness is a straightforward solution that doesn’t skimp on support. This system aims to optimize heel hold, while providing ankle support and unrivaled stability to help reduce fatigue.

H4 / M3 Focus Boa® Fit System – A two reel Boa® system that allows for the upper and lower zones of the boot to be tightened independently.

TX3 Lacing – BOA®’s first textile lace in the snowboarding category, TX3 is constructed from recycled PET with a structural core. This lace provices a softer, more flexible look similar to the characteristics of a traditional lace but the superior closure of a BOA® system.

3D Formed EVA Footbed

This Grips! Premium Rubber Outsole – A K2 exclusive built to offer the best possible performance at the lowest possible weight. An EVA midsole with Harshmellow™ pods makes this quiet underfoot, and a dual rubber compound provides unmatched grip for the parking lot and the boot pack.

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