Bad Design Idea

Hansel and Gretles

My idea for a design that would never work is a shoe that is filled with paint on the bottom and has small holes on the bottom of the sole to leave painted footprints as you walk around. The purpose of this is to be able to backtrack and find out where you have been. Say if you dropped your keys somewhere (which it happens to everyone quite frequently) then you will be able to go back and find them. The reasons that a product like this is that the paint would run out so it would cost a lot of money to keep buying more and a lot of effort to keep refilling them every few minutes worth of walking. You also will be left with having to clean up every footprint you leave, not to mention that paint ruins carpets, but you will end up spending more time cleaning than walking. I would also assume that a shoe full of paint would be pretty heavy to walk around in.
