A slipper or houseshoe is a semi-closed type of indoor/outdoor shoe, consisting of a sole held to the wearer's foot by a strap running over (or between) the toes or instep. Slippers are soft and lightweight compared to other types of footwear. They are mostly made of soft or comforting materials that allow a certain level of comfort for the wearer. This can range from faux fur to leather.

Most slippers are worn in late autumn and winter and on occasion in other seasons.

There are many different types of slippers in the world today, each with varying styles, materials and purposes.

Slip on slippers; These slippers are usually made with a fabric upper layer that encloses the top of the foot and the toes, but leaves the heel open, allowing the wearer to slip into them casually. They are most likely the most common type of slipper as they are quite easy to put on.

Slipper boots; These slippers are made to look like boots. often favoured by females, they are typically furry boots with a fleece or soft lining, and a soft rubber sole. These slippers sometimes are worn outside of the house, as they resemble the sheepskin boots that have been the fashion lately.
