Celebrating 40 years of the RS cushioning system, the PUMA RS-X '40th Anniversary' sports a white knit upper with leather overlays in matching green and white. Royal blue trim delineates the Formstrip logo, while the heel counter shows a red PUMA logo standing out on a yellow background. Reflective details on the toe box, tongue and heel aid visibility in low-light conditions. A sculpted, off-white RS midsole wraps up the look in style.
