👉 A shoehorn is a type of shoe that has a flat, concave heel. It is often used for men's shoes, but it can also be found in women's shoes and other types of footwear. The shape of a shoehorn is similar to that of a round or oval-shaped object, with the heel being slightly wider than the width of the toe. These shoes are commonly worn for wearing under one's feet during activities such as walking, running, or dancing.
