Rain boots are a type of footwear designed to keep your feet dry and comfortable during rainy weather. They typically have a waterproof rubber or plastic upper, a thick sole for traction, and sometimes a pull-on tab or zipper for easy on/off. Rain boots can range in style from classic black knee-high boots to brightly colored wellies (wellington boots) with fun patterns. They are often worn as a practical fashion accessory during rainy weather but also have become popular as a stylish trend.
