A "slip-on" refers to a type of footwear that is designed for easy wear without the need for laces or fasteners. These shoes typically feature a flexible upper and a flat sole, allowing the wearer to simply slide their foot in. Slip-ons are popular for their convenience and comfort, making them suitable for casual outings and everyday use. Common examples of slip-ons include loafers, moccasins, and canvas shoes. They come in various styles, materials, and colors, catering to different fashion preferences. Slip-ons are favored for their versatility, as they can be worn with both casual and semi-formal attire.
