Puma has reissued its RS-Computer shoe. The original RS-Computer, released in 1986, was purportedly the first shoe to incorporate a computerized sensor to record running statistics, such as time, distance and calories burned. It would connect to an Apple IIE or a Commodore 64 with a 16-pin cord. The current upgrade charges with a USB cable but feeds the stats to any Android or iOS device via Bluetooth. The shoes records 30 days of data, presented in a Monthly Statistics tab, and start fresh every month. The new RS-Computer is a limited edition, with only 86 numbered pairs, in a reference to the year of the shoe's original launch. They are on sale at Kith, online in the U.S. and Japan, and at Puma stores in Tokyo, London and Berlin.
