Wellies, short for Wellington boots, are waterproof rubber or plastic boots designed to keep feet dry in wet conditions. They are commonly worn for outdoor activities such as gardening, farming, and walking in muddy areas. The name comes from the 1st Duke of Wellington, who popularized this style of boot in the early 19th century. These boots are typically knee-high and have a sturdy sole for traction. Wellies come in various colors and patterns, making them popular not just for practicality but also for fashion. They are often associated with outdoor festivals and events, where muddy conditions are common.
