A perennial team favorite, the Formula features our bulletproof and lightweight ProFusion™ Chassis, a comfortable 3 degree canted footbed, and 100% Tool-Less adjustability for on-the-go maintenance for maximum on-hill performance. ProFusion™ Chassis: Simple, tough, and lightweight, the ProFusion™ chassis is the go-to standard in the K2 binding collection. On-board tool-less power ramp and toe strap adjustments are paired with multiple ankle-strap mount points to help dial in perfect fit and ideal power transfer. GF Nylon Performance Chassis Material: Injected nylon with integrated fiberglass makes for more response and performance-focused chassis.

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. 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. 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. Integrated EZ Feed Housing: A wider, tapered ladder opening allows for the easiest of entry. 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, 3-hole, and channel mounts.
