The digital RS-100 can only be found at special limited accounts. The RS 100 Digital is limited to 1000 pairs. The RS 100 Digital was originally introduced back in the 80’s as the first computer supported Running shoe. Back then it was so cool to be able to plug your computer into your shoe and see how far, fast, and how calories, etc.. back then not many people could afford computers or even $100 sneakers. Technology has come along way, and so has the Puma RS 100, unfortunately minus the computer hookup. The new and improved color scheme for the Puma RS 100 Digital is White, Magenta Purple and Cyan Blue. Available now at Overkill.
