A shoe hanger, also called a shoe display hanger, is commonly used to hang and display footwear in retail stores for the purpose of space efficient storage and to present footwear to customers. Shoe hangers have secondary functions of providing support for footwear and for displaying key information, such as style and shoe size. Shoe hangers come in a variety of styles for different display purposes and footwear types. The most common styles are wing, hook, and clip designs, which are made from plastic. Designs Wing shoe hangers have an elongated base that terminates at the upper end with a hook. Usually a flat disc appears just below the hook where information about the footwear is displayed. The bottom end of the base terminates into a U-shape. Each arm of the U acts as an element where a shoe can be fitted. These arms often extend and loop back down on each other to create a wing, which offers more support for the shoe. In U-shaped and wing designs, each shoe of the pair is hung adjacent to each other. This design is most commonly used for flat soled footwear such as trainers, sandals, slippers, and pumps. Hook shoe hangers are more basic in their design and resemble small clothes hangers. The arms are far shorter and have a hook at their end. This design is commonly used to hang flip-flops or sandals. Clip shoe hangers are used to hand and display boots. The base is short and terminates at the upper end with a hook. Directly below the hook is a flat disc that acts as a display for information and also as a grip to open the spring clip. The clip displays boots side on as opposed to other shoe hanger designs that display footwear front on.

It was also important to prominently display shoes so that the wearer would have easy access to them. Like modern shoe hangers in retail stores, its secondary function was to support shoes. The main difference between this design and modern shoe hangers was that the soles of the shoes would lie flat against the wall. This early shoe hanger, which was made from wire,
