Puma released a limited edition of their 1986 RS-Computer retro-sneakers with a chip embedded in the module on the heel that records distance, time, and calories burned. Original sneakers through a 16-pin connector could be connected to an Apple IIE, Commodore 64 or IBM PC.
The updated version of the sneaker retained the original look, but added features: a three-axis accelerometer, LED indicators, a USB port for recharging, and Bluetooth for wireless communication from smartphones.
Only 86 pairs of individually numbered sneakers will be available for sale, which will be sold through branded stores in Berlin, Tokyo and London. Sales start December 13th.
