Kind of a neat gimmick for geeky runners (if you are out there). Pioneer is a concept shoe designed by Feijun Chen & Bin Zhao that converts kinetic walking energy into electrical energy.
There is a tiny battery inside the shoe that charges with every step you take. The headlights can run for a full 12 hours (if you are running in the Arctic when daylight is scarce) and shoot the beam 1.5 metres.
The shoe is also water proof.
