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.

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.

CUSTOM CADDI: The foundation of our strap offering, this proven design features durable PU laminates.

PERFECT FIT TOE STRAP: Hinged design fits any boot toe shape, holds well, and sits in a low-profile configuration.

100% TOOL-LESS ADJUSTMENTS: Our traditional bindings have 100% tool-less adjustment capability. Ankle straps and highbacks can be adjusted by hand, and ankle straps can be centered with the pop of a lever. Keep it simple and enjoy.
