The transition from a traditional wooden sole galosh to one of
vulcanized rubber may be attributed to
Charles Goodyear and
Leverett Candee. The qualities of rubber, though fascinating to Goodyear, were highly dependent on temperature: it was tacky when hot, brittle when cold. Vulcanization of rubber tempered its properties so that it was easily molded, durable, and tough. A rubberized elastic webbing made Goodyear's galoshes () easy to pull on and off. Beginning in the early 20th century, galoshes were almost universally made of rubber. Overshoes have evolved in the past decades and now are being made of more advanced materials with new features, such as high traction outsoles. ==See also==
