Slippers are light footwear that are easy to put on and off and are intended to be worn indoors, particularly at home.

The recorded history of slippers can be traced back to the 12th century, the Vietnamese has been already wearing the slippers. But in the West, the record only can be up to 1478. The history record of slippers in the west is about in Sultan when people wear them indoors to slip.

The following is a partial list of types of slippers:

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 favoured by women, they are typically furry boots with a fleece or soft lining, and a soft rubber sole. Modelled 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. The slippers are usually made from soft and colorful materials, and may come in the shapes of animals, animal paws, vehicles, cartoon characters, etc.

Contrary to popular belief, all shoes with a soft fluffy interior are not slippers. Any shoe with a rubber sole and laces, by definition, is a normal outdoor shoe. In India, rubber chappals (flip-flops) are worn as indoor shoes.
