What is a "rain boot"?

A rain boot, also known as a Wellington boot or "Wellies," is a type of waterproof boot that is designed to keep the feet dry in wet weather conditions. They typically reach to mid-calf or knee-high and are made from rubber or other waterproof materials. The boots often feature a textured sole for added traction on wet surfaces and may have a buckle or strap at the top for a secure fit. Originally designed for outdoor work and agricultural activities, rain boots have become a popular fashion item in recent years, particularly in countries with wet climates. They are often worn with casual outfits or for outdoor activities such as hiking or gardening.
