Namaksin is a kind of traditional Korean clog made of wood for protection against mud and rain. It has been worn since the middle period of Joseon Dynasty in Korea (ca. 16-17 C) according to the excavated proof, though it must have been produced long before the Joseon era. The shoes are worn by Koreans of all ages and social positions, usually in the rainy seasons. First, namaksin was made only by a piece of wood tied with rope, but gradually modified according feet’s size. Unlike Japanese geta, namaksin has its heels carved out of one piece with the shoes.
