Have you seen the commercials for those "Z-coil shoes"? Would you ever, in a million years, wear something so goofy?

Seriously! Perhaps if the coil was disguised inside of what looked like a regular tennis shoe, I might be asking if they worked (not that I need them.) But I’ve looked carefully and not once do they indicate that the springs are anywhere but very visible on the bottom of the shoe!

Sometimes I wonder about the native common sense of some people, specifically the inventor in this case.
