The Slipper

Slippers-which of course are bedroom footwear that may be worn in other parts of the house. There are different kinds for instance- Slip-on casuals, which were once considered house shoes by men who lived in castles.

Extending across several types is the Albert slipper, named after Prince Albert of Saxe-Coburg and Gotha, Queen Victoria's consort. A velvet slipper with a leather sole and quilted silk lining, it is worn about the house, particularly with black tie, as well as anywhere that smoking jackets are appropriate. Alberts are offered by all the major English shoemakers as well as a couple companies that specialize in them exclusively.

Lesser slippers tend to be of moccasin construction, where a single piece of the slipper's material simply extends under the foot. The pictured version is one half a dozen versions that were originally designed by Henri Bendell in the 1940's and are sold to this day as Belgian Shoes and, according to Alan Flusser in one of his older books, the leopard version is the one to get. 

Indoors ,that's the best way to treat soleless slippers. They'll give many years of service if they're worn on carpeting but a dozen blocks on city sidewalks will be the death of them.
