slipper

Slipper refers to a light indoor shoe designed for comfort and ease of use. Typically backless or open-heel, it is worn indoors to provide warmth and protect floors while keeping the feet comfortable. Slippers are usually slip-on and have a soft upper with a padded or cushioned sole. The outsole is often made of rubber or foam to provide traction, while the interior may be lined with fleece, wool, sheepskin, or other soft materials.

Common forms include house slippers with flat or low heels, moccasin-style slippers with hand-sewn uppers, and backless mule slippers. Some slippers are designed for light outdoor use, while others are strictly for indoor wear. Slipper socks combine the form of a sock with a non-slip sole.

Materials vary widely, from knitted fabric or fleece to leather, suede, or sheepskin. Care instructions depend on materials; fabric slippers may be machine-washed and air-dried, whereas leather or suede slippers require gentle cleaning and conditioning.

Slippers have appeared in many cultures and historical periods. In East Asia, traditional inner slippers or embroidery were used in households and temples. In Europe, soft footwear for indoor use developed in medieval and modern times as domestic comfort items. In contemporary retail, slippers are produced for home use and can be marketed as luxury items with fur linings or decorative embroidery.

Today slippers are widely used in homes, hospitals, and hotels to maintain cleanliness and warmth; some institutions require special non-slip or closed-back designs for safety. The term is often contrasted with outdoor shoes and sandals, which are worn outside.
