Rain boots are boots suited to protect feet from inclement weather. Rain boots are waterproof and made from either rubber or other equivalents. Gore-tex, one of the latest materials used for rain boots, is completely waterproof. Rain boots are usually knee-high, but are also available low cut, just above the ankle, or high cut, all the way up to the thigh. Rain boots can also be used for snow, mud, and chemical waste because they provide protection, dryness, and warmth. Many rain boots are made with inner liners of flannel or other warm materials for use in cold weather.
