From the mad scientists in the K2 lab, the versatile K2 Formula snowboard binding is an all-mountain freestyle binding that isn’t afraid to mix it up in the steeps, parks, or streets and is the preferred binding of global K2 pros and ams alike.

The Formula is built on our Profusion™ Chassis, a mid-to-stiff flexing fiberglass-filled-nylon construction that provides support and cushion for big tricks in the park and pointing it down spicy lines. The AT Nylon highback is responsive with just the right amount of flex and features our Gap Eraser™ forward lean adjustment to customize the response of your board. This forward lean technology allows your highback to have complete contact with your heel cup at any degree of forward lean. Complete contact equals full response. The padded Custom Caddi™ 3D ankle strap provides a supremely comfortable and secure feel when the consequences are high, and the PerfectFit™ 2.0 toe strap hinges to fit any snowboard boot toe profile for comfort and fast response.

The Formula’s Power Ramp is adjustable to evenly match the bottom of your boot outsole and combines with a 3º cant built directly into the chassis to create a natural riding position for big landings, solid take-offs, and even balance on all terrain.

Lastly, the aluminum ratchets are tough as hell and feature our integrated EZ Feed™ design and make strapping in quick and hassle-free.
