Clogging is an percussive folk dance whose American roots are buried deep in the heart of the Appalachian Mountains. Constant shuffling of the "floor" foot is one of the major characteristics that distinguishes clogging from tap dancing. Flatfoot dancing is largely based on a low-to-the-floor style that emphasizes intricate rhythms and creative percussive dancing. Buck dancing emphasizes percussive rhythms with a greater use of the heel and toe. The style uses a greater bent leg position that distinguishes it from "shuffle" clogging.
