What is a low-heeled shoe without laces called?

A low-heeled shoe without laces is called a loafer. Loafers are slip-on shoes, usually with a low vamp and a separate sole and heel, designed to be put on without fastening. Their relaxed construction places them between formal lace-up shoes and casual slippers.

The modern loafer developed from slip-on footwear associated with Norway and was popularized in the United States during the early 20th century. The Bass Weejuns, introduced by G. H. Bass in 1936, helped establish the penny loafer, whose saddle strap has a small diamond-shaped opening traditionally large enough to hold a coin.

Not every laceless shoe is a loafer. Moccasins are traditionally soft shoes based on Indigenous North American footwear construction, although modern commercial moccasins may resemble loafers. A brogue describes decorative perforations, not a particular fastening style, and an Oxford is normally defined by its closed-lacing system.

Loafers come in several styles, including penny, tassel, horsebit, and Belgian loafers. Depending on the material and design, they can be worn with business clothing, smart-casual outfits, uniforms, or everyday clothes.
