Types of slippers include: • Open-heel slippers – usually made with a fabric upper layer that encloses the top of the foot and the toes, but leaves the heel open. These are often distributed in expensive hotels, included with the cost of the room. • Closed slippers – slippers with a heel guard that prevents the foot from sliding out. • Slipper boots – slippers meant to look like boots. Often favored by women, they are typically furry boots with a fleece or soft lining, and a soft rubber sole. Modeled after
sheepskin boots, they may be worn outside. •
Sandal slippers – cushioned sandals with soft rubber or fabric soles, similar to
Birkenstock's cushioned sandals. • Evening slipper, also known as the "Prince Albert" slipper in reference to
Albert, Prince Consort. It is made of velvet with leather soles and features a
grosgrain bow or the wearer’s initials embroidered in gold. Some slippers are made to resemble something other than a slipper and are sold as a
novelty item. They are usually made of soft and colorful materials and may come in the shapes of animals, animal paws, vehicles, cartoon characters, and so on. Not all shoes with a soft, fluffy interior are slippers. Any shoe with a rubber sole and laces is a normal outdoor shoe. In India, rubber
chappals (flip-flops) are worn as indoor shoes. ==In popular culture==
