Flat heel are shoes with a very low heel, and in some cases no heel at all, that provide minimal elevation. Flat heel shoes come in a variety of styles, including sandals, loafers, moccasins, oxfords, deck shoes, ballerina flats and boots. Flat heel shoes are generally considered comfortable footwear, mostly due to their flexible, lightweight soles and low heels, which provide stability.
