Clogs are a type of footwear made in part or completely from wood. Used in many parts of the world, their forms can vary by culture, but often remained unchanged for centuries within a culture.

Traditional clogs remain in use as protective footwear in agriculture and in some factories and mines. Although they are sometimes negatively associated with cheap and folkloric footwear of farmers and the working class, some types are considered fashion wear today, such as Swedish träskor or Japanese geta.

Clogs are also used in several different styles of dance, where an important feature is the sound they produce against the floor. Clog dancing is one of the fundamental roots of tap dancing, but with tap shoes the taps are free to click against each other and produce a different sound from clogs.
