K2 Sports Raider Snowboard Boots With upgraded fit and functionality comes progression, and that’s precisely what we had in mind when we designed the K2 Raider snowboard boot. A long-time favorite of resort employees and progressing snowboarders alike, we packed all the essentials into the mix in the Raider, starting with a BOA® Fit System featuring H5 Coiler. This securely closes the shell using a TX3 BOA® lace for the perfect fit and helps get you in and out of your boots at the beginning and end of the day. Next, we added Fast-In liner lacing to maximize fit and keep the liner snug against the contours of your feet. No matter the shape of your foot, the ultra-warm, heat-moldable, and breathable Intuition™ Comfort Foam 3D liner hugs every nook and cranny for a great fit right out of the box. We added internal and external J-bars to the liner to increase responsiveness when turning, wrapping your ankles with support and cushion, and added an EVA footbed for comfort. Category BOA® Ability Beginner, Intermediate Footbed Harshmellow™ Insole Snowboard Boot Category BOA® Liner Internal & External J-Bars Adding J-Bars to a liner helps add structure and reduce heel lift. 3-Point Harness Liner Lacing A traditional liner harness with a pull lace and three contact points hugs the ankle to provide additional support and unrivaled stability to help reduce fatigue. Insole Harshmellow™ Insole Freestyle-friendly single-density insole using Harshmellow™ from toe to heel for ultimate impact absorption. Lacing BOA® Fit System Powered by H5 BOA®’s all-new H5 dial platform provides a micro-adjustable, multi-directional user experience that is engineered for precision fit through instant tightening or loosening on the fly. Impact resistant, durable, and performance-driven, the H5 BOA® Dial ejects on severe impact and is easily re-inserted into the boot. TX3 BOA® Lace The best of both worlds. TX3 is a flexible and low-friction textile lace used on snowboard boots to provide a soft, modern design aesthetic with lasting durability and strength. Outsole RollSole™ Outsole RollSole™ Outsole design allows maximum medial mobility for tweaking grabs and, drop-knee turns.
