Product InformationWith upgraded fit and functionality comes progression, and thats 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 of the essentials into the mix on the Raider, starting with an H4 Coiler BOA Fit System. This securely closes the shell using a stainless steel BOA lace for the perfect fit and helps to effortlessly 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.We built the whole thing on a grippy, lightweight rubber outsole for hiking and exploring new terrain and filled the midsole with our proprietary Harshmellow foam, helping to increase impact absorption and help dampen vibration underfoot.
