Sonic Men's Snowboard Binding

The Perfect Jump-Off Point for your Snowboarding — the all-mountain K2 Sonic is the perfect place to start. The soft but supportive K2 Sonic utilizes the strength and durability of K2's ProFusion™ Chassis and blends a 3° inward cant to put the user into a natural riding position. Atop the footbed, an EVA footbed adds to the comfort factor and absorbs vibrations — the result is better balance for anticipating and riding through all terrain. The durable AT PC Highback is responsive with just the right amount of flex for easy edge-to-edge transitions and features Gap Eraser™ forward lean design for customizable response. The padded P.I. 3D EVA ankle strap and Perfect Fit toe strap are comfortable and easy to use — perfect for strapping in with gloves or mitts. The Power Ramp easily slides to match your boot outsole shape for quick response on turns and jumps. With K2's Toolless design philosophy, all adjustments can be made by hand on the mountain to fine-tune the fit without tools — perfect for beginners who are still dialing in the ideal binding feel.

Perfect Jump-Off Point
"The perfect place to start" — the most entry-level friendly binding in K2's men's collection. Perfect for beginners still dialing in the ideal binding feel.
ProFusion™ Chassis + 3° Inward Cant
Rugged fiberglass-filled-nylon ProFusion™ Chassis (same as Formula + Bond + Indy) + built-in 3° inward cant puts the user into a natural riding position. Premium composite construction at an entry-level price.
AT PC Highback + Gap Eraser™ Forward Lean
Durable AT PC Highback — responsive with just the right amount of flex for easy edge-to-edge transitions. Gap Eraser™ forward lean design allows customizable response — full contact at any angle of forward lean.
Padded P.I. 3D EVA Ankle Strap
Comfortable and secure hug for your feet while allowing tweaking and flex on grabs and presses. Easy to use whether strapping in with gloves or mitts. Different from the Formula's padless Bender strap — the Sonic uses a more cushioned design for comfort.
Perfect Fit Toe Strap
Hinge design can be shaped to any snowboard boot toe box shape — adapts to a wide range of boot sizes with maximum response and feel.
Adjustable Power Ramp
Easily slides to match the shape of your boot outsole for quick power transfer on turns and jumps. Adjustable on-the-fly to dial in the response for any boot or riding style.
100% Toolless Adjustment
"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 still dialing in the ideal fit.

Strap Care
The P.I. Ankle Strap and Perfect Fit toe strap are designed for long-term durability. Inspect periodically for wear and replace if needed. The Padded P.I. 3D EVA construction is durable but keep the strap clean for optimal comfort.
Chassis & Mounting Care
The ProFusion™ fiberglass-filled-nylon chassis is built for durability. Wipe off dust and grime with a damp cloth after riding. The Multi-Compatible Disc should be kept clear of ice buildup — periodically check that the disc and module system are functioning properly.
Highback + Forward Lean Care
The AT PC Highback + Gap Eraser™ forward lean system is precision-engineered. Keep the forward lean mechanism clear of ice and snow. Periodically test the lever for proper engagement.
Storage
Store the bindings in a cool, dry place between sessions. The 100% toolless system means you can fully release all tension for long-term storage. The chassis should be kept dry — wipe completely after riding in wet conditions.
