I would invent a washer that could wash any kind of shoes without tearing them apart, or messing up their color and appearance. It would contain buttons from sandals all the way to super heavy duty boots. It would be very useful for girls that have so many shoes or even moms that have so many kids that are so clumsy and dirty their shoes like crazy! You could have your shoes shined, to even your husbands hard working boots scrubbed! All your shoes would look spotless clean and NEW!
