Slip-ons are typically low, lace-less shoes. The style which is most commonly seen, known as a loafer or slippers in American culture, has a moccasin construction. One of the first designs was introduced in London by Wildsmith Shoes, called the Wildsmith Loafer. They began as casual shoes, but have increased in popularity to the point of being worn in America with business suits. Another design was introduced as Aurlandskoen (the Aurland Shoe) in Norway (early 20th century). They are worn in many situations in a variety of colors and designs, often featuring tassels on the front, or metal decorations (the 'Gucci' loafer).
