The SPX 12 GripWalk® binding is designed for discerning freeriders who view mountains as a playground to be fully exploited. The Full Action toe piece and SPX heel come together to provide multi-directional release for optimal safety and superior shock absorption for maximum reduced unwanted pre-release. Control and power are its leitmotifs. It's compatible with ISO 5355 A and GripWalk® (future ISO 23223 A) adult boot soles. This tool-free system adapts to outsoles measuring 260 mm to 375 mm in length.
