PUMA RS-X? Neo Fade Shoes, Color: white, yellow, black, Material: Mesh, X marks extreme. Exaggerated. X3 takes it to a new level: cubed, enhanced, extra. In 2020, we reboot our RS design and take it to an extra, thrice-exaggerated form by stripping the silhouette down to the basics then building it up with stronger material mixes and colors. This pack arrives in a simplistic base color with a subtle fade around the collar giving a vibrant look to the shoe.
