  • Patent number: 5996251
    Abstract: An unusually versatile dance shoe usable for both jazz dancing as well as tap and character dancing combining the flexibility of a jazz dancing shoe and the support strength of a shoe used for character/tap dancing. This combination shoe has at a minimum a semi-flexible arch made of hard rubber, flexible inserts on the sides of the shoe upper above the arch and a hard leather sole and heel that can accept taps for tap dancing. In the preferred embodiment, for manufacturing purposes, the rubber arch is part of a continuous rubber layer that extends front and back over the leather heel and sole so that it is the whole length and width of the shoe. Consequently, the dancer has the ability to achieve the aesthetic result from dancing flexibly such as by standing fully on pointe on the tip of the shoe or standing three-quarters on pointe while simultaneously having the support and strength necessary to tap dance and perform character dance steps such as stomping, kicking, scuffing, slamming and clicking.
