When you stop on a gymnasium floor, you are creating friction. Friction results in the release of various forms of energy. We usually think of heat energy being produced. In this case, sound energy is also produced. Since certain shoes squeak, while others do not, it must be the vibrations of the rubber of the shoes producing the sound energy.
