K2 Thraxis Snowboard Boots 2025

Rubber Reinforced Flex Zone Upper: Abrasion resistant reinforced outsole rubber is placed in areas of high stress to extend the life of the boot and increase durability.

Intuition® Pro Foam 3D Liner with SpaceHeater™: 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.

BOA® Conda™ Liner Lacing: A patented K2 liner lacing system that uses a urethane harness to gently hug your ankle, creating unrivaled heel hold. BOA® Conda™ allows for adjusting liner tightness and heel hold on the fly from outside of the boot, even with gloves on.

H4 Coiler BOA® Fit System with 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.

Harshmellow™ Pro Footbed: Three separate compositions, Pro, Plus, and Base, now all incorporate K2’s proprietary Harshmellow™ damping into the layup of the footbed. The result is superior vibration absorbing and comfort for all-day excursions into the backcountry or hiking and riding around the resort.

Vibram® V5 Outsole: Vibram® V5 Outsole features a full EcoStep rubber (30% regrind) with and Harshmellow™ pods under the toe and heel to reduce noise underfoot. The V5 Outsole is the perfect combination of sustainability and performance.

Eco-Harshmellow™ Midsole: 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.

Endo™ 2.0: Endo 2.0 is the most technically advanced boot construction available. An injected heel counter construction adds strength and durability to your boot, giving it the same response season after season. The Endo 2.0 design allows for a more precise and smooth flex with a snappy rebound to power you out of any landing or turn. With an ultra durable TPU construction, the Endo 2.0 provides lasting comfort, response and durability for all styles of riding.

S’Cafe™ Coffee Mesh: With functionality and sustainability in mind, K2 coffee mesh is made from recycled post-consumer coffee grounds that is combined with post consumer recycled polyester. This mesh enhances odor control and moisture management of our standard lining mesh and is made from 95% recycled material with no added chemicals.
