Definition: The heel is the outer part of the shoe that is placed under the heel of the foot. Shoe heels come in a wide variety of styles, shapes and heights. In fact, even shoes that are referred to as "flats," will often have a heel, although it's very low.
Some casual shoes, such as sneakers, do not have a separate "heel," but instead have an outsole that runs the length of the shoe.
