Overshoe

Galoshes, also known as dickersons, gumshoes, or overshoes, are a type of rubber boot that is slipped over shoes to keep them from getting muddy or wet. In the United States, the word galoshes may be used interchangeably with boot, especially a rubberized boot. In the United Kingdom, however, a galosh is an overshoe made of a weatherproof material to protect a more vulnerable shoe underneath and keep the foot warm and dry.

The word comes through French (galoche) and Latin from Greek and originally meant a shoemaker's last; literally "wood" + "foot". By the 14th century it had been transferred to English style clogs, that is those with a wooden sole and fabric (e.g. leather) upper. By 1572 the term also applied to "a Gallage or Patten"; that is, an overshoe with a shaped wooden base to raise the wearer's good shoes off the ground.

In Turkey, the word refers to a polythene overshoe that is worn temporarily when visiting homes or offices, to protect the floors against dirt from the outside.

"Goloshes" appears to be the older spelling of galoshes used previously in Great Britain. The spelling perhaps changed around 1920 to the present-day spelling.

The transition from a traditional wooden sole 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 (circa 1890) easy to pull on and off.

Galoshes are now almost universally made of rubber. In the bootmakers' trade, a "galosh" is the piece of leather, of a make stronger than, or different from, that of the "uppers", which runs around the bottom part of a boot or shoe, just above the sole.

A more modern term for galoshes could be rubber boots or bad weather shoes. Overshoes have evolved in the past decades and now are being made with more advanced features, such as high traction outsoles.
