Flat soles refer to the bottom part of shoes that do not have any significant elevation or arch. These soles provide a level surface, which can enhance stability and comfort for the wearer. They are commonly found in various types of footwear, including sneakers, sandals, and ballet flats. Many people prefer flat soles for everyday activities, as they can reduce the risk of foot pain and discomfort. Additionally, flat-soled shoes are often recommended for individuals with certain foot conditions, as they promote a more natural foot position.
