Overshoes are a type of footwear designed to protect shoes and feet from wet or muddy conditions. They are typically made of rubber or plastic and come in a variety of styles. The term 'overshoe' can refer to three different types of footwear: galoshes, boots, and gaiters. Galoshes are slip-on waterproof covers that fit over the top of shoes. Boots are tall, waterproof footwear that cover the foot and ankle. Gaiters are waterproof leg coverings that fit around the calf and ankle. All three types of overshoes provide protection from wet and muddy conditions and can be worn over regular shoes.
