A shoe horn is a tool designed to help people put on shoes more easily. It is typically made of plastic, metal, or wood and has a curved shape that allows the heel of the foot to slide into the shoe without damaging the shoe's structure. Using a shoe horn can prevent the back of the shoe from bending or collapsing, which can prolong its lifespan. Shoe horns come in various sizes and styles, catering to different types of footwear, including boots and dress shoes. They are especially useful for individuals with limited mobility or those who wear orthopedic shoes. Many people keep a shoe horn near their entryway for convenience.
