  • Patent number: 7287293
    Abstract: A system for custom fitting athletic shoes to an individual wearer includes a foot measurement device, an adjustable footform and an infrared activation chamber. Shoes of a single width for each length size have at least a portion of the upper made of heat malleable material to be custom fitted for width. Foot measurement data is used to calculate length size, width size and a number of custom adjustment factors. After the length size is calculated, the appropriately sized shoe and last are assembled together and subject to infrared radiation until the heat malleable material becomes plastic. Adjustments are then made to the last in accordance with the adjustment factors to provide custom width sizing. After further heat treatment to set the shoe upper and cooling, the shoe is complete. In this manner, if used in a retail setting, shoes are custom fitted to the wearer in a matter of minutes.

  • Publication number: 20030177593
    Abstract: A device for retaining the shape of a shoe includes a tapering base member having an arch cross section and a shoe expansion member defining a cavity removably receiving the base member therein. The base member has opposite side walls and an arcuated top wall defining a groove in which a stair-like configuration is formed, having a first number of steps. The side walls of the base member each form first serration. The shoe expansion member has a bottom in which the cavity is defined and a top side configured to closely fit into a shoe for retaining the shape of the shoe. The cavity is defined by opposite side walls and a top wall. The top wall of the cavity has a stair-like structure having a second number of steps. The side walls of the cavity form second serration. The stair-like structure of the cavity is at least partially engageable with and supported by the stair-like configuration of the top wall of the base member.

  • Patent number: 6467115
    Abstract: A sheet of flexible and resilient polymer material is rolled into a tubular configuration and inserted into the shaft of a boot deeply enough to reach the vamp and quarters from which the shaft uses. The rolled sheet, when released, expands under the bias of its own resiliency and bears against the inside of the shaft, thus stabilizing the shaft in an upright position above the quarters and vamp. The upper end of the rolled sheet projects above the upper margin on the shaft, and here the sheet may bear a trademark or other indicia.
