Rubber was a type of stretchy material made from a secretion of the rubber tree. It was used to make rubber bands.
Because of its non-conductive properties, it was used for the soles of shoes worn by researchers experimenting with electricity. In 2365 while playing Sherlock Holmes Program 3A, Data, as Holmes, noted that a set of footprints left behind bore dark markings from these kinds of soles. (TNG: "Elementary, Dear Data")
