Wellies (short for Wellington boots) are a type of waterproof rubber or plastic boot that covers the foot and the lower part of the leg. They are often worn to protect against wet weather and muddy conditions. Some common synonyms for wellies include gumboots, rain boots, waders, waterproof boots, and mud boots. In different countries and regions, there may be other terms for this type of footwear, including galoshes, overshoes, and rubbers. Regardless of the name, wellies are a practical and reliable choice for anyone who needs to keep their feet dry and clean in wet or muddy conditions.
