Cool shoes, for cool feet

If you're making the long walk to a soccer stadium, or you're just on your feet for hours a day, you might want to consider a pair of "cool shoes." Not as in trendy - but actually cool, and comfortable. They were created by a young Kenyan inventor who wanted to soothe his mother's aching feet. They're made entirely from trash and bits and pieces of old electronics. Jonathan Miller reported the story for Audio Flux, an independent platform for short-form audio storytelling.
