  • Patent number: 5035069
    Abstract: A ballet slipper and method of manufacturing the same is disclosed. The slipper has an integral shank and toe box molded from a flexible thermoplastic polymeric material which can be adjusted by the dancer to conform to her foot. The toe box has a platform at its forward end which is connected by a curved radius to the shank. A layer of resilient polymeric material lines the interior of the upper portion of the toe box and extends backwardly from the edges of the toe box. A layer of shock absorbing material covers at least a portion of the upper and lower surfaces of the shank, and the platform and curved radius of the toe box. A wicking outer covering fits over the integral shank and toe box and has an elasticized throat and a panel formed from a durable non-slip material to cover the platform and curved radius of the toe box.
