Some of you might remember the TV show “Get Smart”. They were still showing reruns of it in the 90's when I was growing up, so I still remember Maxwell Smart answering his shoe phone. I always thought it would be cool to have one. Then cell phones became popular and I stopped caring about it.
Now that fond memory has been brought up by the Tennis Shoe Phone. Although it isn't quite as travel-friendly as the one from the TV show, it's still a great piece.
You can talk like a secret agent for only $49.00. Just don't try to wear it out of the house, you only get one.
