he 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 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.
