Optimizing comfort and progression friendly performance for beginners on a budget, the K2 Sonic Snowboard Binding proves that entry level doesn't have to be lacking in ergonomic design and support. Serving up a medium soft flex that's great for riders looking to hone their carving skills, the binding's Airframe highback is cored out for freedom of movement and significant weight savings. Tool less forward leans lets you dial in more response on the fly, should you desire a bit more energy transmission for arcing wide radius carves and riding at higher speeds. The Pro Fusion baseplate is super lightweight, with formed EVA shockpads along the toe and heel to soak up vibration and shock from fatiguing your ride. The adjustable Power Ramp slides forward to accommodate varying boot sizes, maximizing toeside response when you're turning down the mountain. The Caddi ankle strap is 3D formed to snugly support your boot without nasty pressure points. The tool less Universal toe strap conforms over the tip of your boot, pulling your boot back into the binding's heelcup for a better fit and feel. You can also wear it over the top, should you prefer a more traditional feel. Both straps are tool less adjustable for maximizing the fit and support on the fly. Additionally, this binding comes with a universal style mounting disc that's compatible with regular four hole boards, as well as Burton's Channel boards.
