PUMA RS-X? Millenium Shoes, Color: white, dark blue, Material: fabric, 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. Inspired by the early 2000"s, the Millenium pack features an easy mesh upper while playing on different layers materials and colors.
