In 1986, Puma gave new meaning to the word sneakernet with the introduction of its RS-Computer running shoe that integrated a digital pedometer in the heel that could interface with your Apple IIe or Commodore 64 computer. See vintage video below. Now the RS-Computer is back with contemporary technology. I just wouldn't recommend wearing them through airport security. From Hypebeast:
Updating the 33-year-old trainer for today, PUMA's updated version no longer requires a 16-pin cord. It can be charged via USB and can now connect wirelessly to your mobile phone via Bluetooth. Other updated features include a miniature 3-axis accelerometer, an extended memory that records 30 days worth of running data, LED indicators, and a rechargeable lithium-polymer battery.
