Released in 1986, literally decades before its time, the Puma RS-Computer Sneaker is seeing a modern reissue. The heel counter of the original housed a computer chip (hence the Running System Computer moniker) that recorded stats like distance, time, and calories spent. Back in the day, you needed a cable and an Apple IIe or a Commodore 64 to read them back. Now the shoe connects to your phone over Bluetooth, charges via USB, and stores up to 30 days worth of what we can only assume is slightly more accurate data. Limited to just 86 pairs worldwide.
