K2 Formula 2025

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 Bender™ 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.

TECHNOLOGY

GF PROFUSION™ CHASSIS:

Integrated fiberglass materials combine with a classic shape to deliver a lightweight and rugged framework that is the go-to standard in the K2 binding collection.

AT NYLON HIGHBACK:

Stiff, durable, and temperature resistant nylon provide maximum responsiveness and support. Customize your forward lean without the need for tools or a traditional forward lean block.

GAP ERASER™ FORWARD LEAN:

Gap Eraser™ technology completely eliminates all gapping between the boot, highback, and heel cup, creating an even stronger bond between you and your snowboard. Better contact means better response.

BENDER™ ANKLE STRAP:

Twist and shout. Our Bender™ strap is our most flexible padless ankle strap option. We created it to improve freestyle mobility and help you tweak until those bindings creak.

PERFECT FIT™ 2.0 TOE STRAP:

Patented toe strap technology that uses flexible hinges and lock levers to custom fit the toe strap to any snowboard boot silhouette.

3° CANTED FOOTBED:

Canted 3° to match your natural leg position during riding. More support to the outside of the foot provides improved control while reducing fatigue.

100% TOOL-LESS ADJUSTMENTS:

Once mounted to your board, all strap and highback adjustments can be done on-the-fly without the need for screwdrivers or other tools.

ALUMINUM RATCHET:

Aircraft-grade aluminum is used to make the most bombproof ratchets on the market.

4" MULTI-COMPATIBLE MOUNT DISC:

Compatible with our ProFusion™ Chassis, the 4" Multi-mount disc focuses on power transfer and lets you mount your snowboard binding to 4-hole and channel mounts.
