With its bold debut in 2000, the Shox R4 broke the mold. The silky smooth synthetic upper takes design cues from space suits and astronaut gear. The flowing lines, laser-cut perforations and bold style help propel you forward. Four compressed columns elevate the heel for structure and responsiveness. Dressed in sleek black synthetic leather and Max Orange accents, this stunning edition propels the R4 further into the future. Designed with a rebellious spirit.
