K2 Sonic Bindings | 2026

The all-mountain K2 Sonic snowboard binding is the perfect place to start. The soft but supportive K2 Sonic utilizes the strength and durability of our ProFusion™ Chassis as the foundation of the binding and blends a 3º inward cant to put the user into a natural riding position. Atop the footbed, an EVA footbed is added to up the comfort factor and absorb vibrations. The result? Better balance for anticipating and riding through all terrain. Our durable AT PC Highback is responsive with just the right amount of flex for easy transitions from edge to edge. It features our Gap Eraser™ forward lean design to customize the feel and give you the most response out of any forward lean design in the industry. The padded P.I. 3D EVA ankle strap and Perfect Fit toe strap are comfortable and easy to use whether strapping in with gloves or mitts. The Power Ramp easily slides to match the shape of your boot outsole and has a quick response while turning or setting up to hit jumps and side hits. The K2 Sonic also features our Toolless design philosophy. Once the binding is mounted to the board, you can make all adjustments by hand while on the mountain to fine-tune the fit without carrying a tool or stopping at the lodge--perfect for beginners who are still dialing in the ideal binding feel.
