Ballet flats are derived from a woman's soft ballet slipper, with a very thin heel or the appearance of no heel at all. The style usually features a ribbon-like binding around the low tops of the slipper and may have a slight gathering at the top-front of the vamp (toe box) and a tiny, decorative string tie. Ballet slippers can be adjusted and tightened to the wearer's foot by means of this string tie
