The K2 Sonic snowboard binding is the ultimate jump-off point for progressing riders looking to build confidence all over the mountain. Built with a soft and forgiving flex rating of 3 out of 10, the Sonic utilizes the strength and durability of K2's ProFusion Chassis as its foundation, blending a 3-degree inward cant to put the rider into a natural, ergonomic stance. An integrated EVA footbed dampens vibration and absorbs impact for improved balance through all snow conditions. K2's durable AT PC Highback delivers responsive edge-to-edge transitions and features the Gap Eraser forward lean system to eliminate space between the boot and highback for maximum contact. Comfort-focused P.I. ankle straps and form-fitting Perfect Fit 2.0 toe straps keep feet locked down securely. Backed by K2's tool-less adjustment philosophy, every strap and highback setting can be dialed in by hand directly on the hill without needing a screwdriver.
