Why do they call detectives gumshoe's?
Originally, gumshoe referred to a shoe with a rubber sole, specifically, galoshes or (more relevant to our purposes) sneakers. The senses of gumshoe leading to the 'private detective' sense all have to do with the idea that rubber-soled shoes give the wearer the ability to walk stealthily.
