Union Source Balance is at the core of the Union Source. It takes the Direct Connect platform from the Source FC and Source Pro and dials back the aggressive feel for a smoother, more versatile ride. A more forgiving highback, wider ankle straps and a nylon baseplate make it comfortable and supportive all day - while keeping the low, disc-free connection to the board that defines the Source line. With no mounting disk and a reduced baseplate height, you sit closer to your snowboard for natural, immediate board feel without the stiffness of the carbon models. Best for: Intermediate to advanced all-mountain riders who want Source-level board feel in a friendlier, more forgiving package.
