Abstract: A slip-on, slip-off stabilizing support accessory for a stiletto heel. The device is a unitary molding of semi-rigid, resilient plastic material formed with a generally hourglass configuration, with outwardly concave, resiliently flexible side walls for frictionally engaging opposite sides of a stiletto heel. An outwardly flared top opening facilitates application of the device to the heel, while an outwardly flaring bottom configuration provides a greatly enlarged ground contact area. Front and back edges of the side walls are of outwardly concave shape. Front and back wall structures, formed by relatively narrow, spaced-apart elements, enable the side walls to be flexed for easy application to heels of various sizes, while firmly gripping heels of the smallest size.
