A heel is the bottom, back part of a shoe or boot that provides elevation. The styling and construction of a heel may vary (i.e., stacked, stilletto, spiked, sculptured, kitten).
About Open Toe Shoes:
Open Toe Shoes are any styling of shoe in which the uppers do not extend across the toes and the toes are therefore exposed.
