Abstract
Abstract Apparatus is disclosed for attachment to shoes to create tap dancing shoes, including heel and toe attachments. Each of the attachments has two pieces, one of which is fixedly attached to the shoe along respective outer edges, having a center cutout with a bridging member proximate one end. The second piece loosely fits within the center cutout of the first piece, and has a pair of projecting ears which loosely nest within cross axis grooves in the first piece, the second piece also having a forward lip and surface for contacting against the bridging member of the first piece for creating a tapping sound.
