K2 Sonic Snowboard Bindings. 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 the 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.
