Estimating the term…
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.
A shoe comprising an upper, a midsole and an outsole, said upper of said shoe comprising at least one activation zone made of a heat malleable material to provide a customized width and girth fit;
A shoe comprising an upper, a midsole and an outsole, said upper of said shoe comprising a first material and at least one activation zone made of a second material that is sensitive to an applied energy source to become plastic and set upon application of energy to provide a customized width and girth fit;
A shoe comprising an upper for surrounding at least a portion of a wearer's foot, said upper comprising a first material and a second material different from the first material, and a sole unit disposed underneath the upper for providing a ground engaging surface, said upper of said shoe further comprising at least one activation zone, the at least one activation zone made of the second material, wherein the second material is sensitive to an applied energy source as to become plastic upon application of energy, and set upon removal from energy source, said upper adapted to be fitted on a footform last to provide a customized width and girth fit by plasticization and set of said activation zone.
