  • a shoe last is a solid form around which a shoe is molded.
  • Shoe lasts are utilized by shoemakers to construct shoes. The fit of a shoe depends on the design, shape and volume of the shoe last. The shoe last represents the anatomical information of the foot and is designed for a particular heel height and toe shape.
  • a shoemaker's shoe last collection typically includes many different styles of shoe lasts, i.e., different heel heights and toe shapes, whereby for each shoe last style the shoemaker will often have a complete size run.
  • shoe lasts were made of hardwoods, such as maple or beech. Modern day shoe lasts, however, are constructed of high-density plastics.
  • Toe shapes can be, for instance, round, pointed or squared. If shoes with different toe shapes are desired, then different shoe last styles need to be used.
  • the shoe lasts in a shoemaker' s last collection were at some point in the past developed by referring to a foot of one or more individuals. Once these shoe lasts are developed, however, shoes are mass-produced from these shoe lasts and sold, for example, at retail stores. Custom shoes are also made from shoe lasts.

For example, since adjustment measurement for foot length was determined to be 8.57mm as described above and assuming the length of base last 615 had to decreased by 1mm according to the feedback from the individual used for test purposes, last manufacturer 115 increases the length of template last 610 for left foot 505 by 7.57mm, instead of 8.57mm when using template last 610. The adjustment measurement regarding the " length " 502 of left foot 505 sent to last manufacturer 115 would therefore be 7.57mm. Similar modifications, whether adding to or decreasing from the size of the respective base last, are made for any other adjustments measurements.
  • Each pair of custom lasts are assigned a unique last identifier.
  • unique last identifiers can be one or more letters and/or numbers.
  • the last identifier identifies the template last that was used in developing the custom last and the customer associated with the custom last.
  • An example of a last identifier for a particular customer, Mary Jones could be B67MJ. Based on this last identifier, system 100 would know that the customer is Mary Jones due to the initials MJ in the identifier, that she has chosen a sandal with a 90mm heel since the letter B was previously assigned to identify such lasts and that her data ⁇ measurements stored in memory unit 150 and/or memory unit 135 are referenced by numeral 67. Such information is later used in order to retrieve custom lasts associated with a particular customer.
  • Lasts can be stored digitally and/or physically stored by last manufacturer 115 or at main facility 110 for future reference.
  • the customer last data can also be transmitted to processing unit 130 for storage in memory unit 135.
  • the physical custom lasts 805 manufactured by last manufacturer 115 are thereafter sent to shoe manufacturer 120.
  • the pair of custom shoes are manufactured by shoe manufacturer 120, in 335.
  • the pattern of the corresponding shoe style is modified by shoe manufacturer 120 according to the custom last measurements and material (s) selected by the customer.
  • the pattern can be adjusted manually and/or using a CAD software program. Thereafter, the custom shoes are picked up by or shipped to the customer.
  • scanning unit 140 and processing unit 145 determine the measurements of a volunteer's feet and based on those measurements using software application (s) stored in memory unit 150 are operable to automatically adjust the elevation of the last heel from a flat position. More particularly, scanning unit 140 and processing unit 145 determine the appropriate measurements for a pair of test shoe template lasts from the scan data regardless of the desired heel height and/or toe style for the pair of test shoes. Upon adjusting the heel height, processing unit 145 either increases or decreases the other measurements associated with the template lasts. Thus, no need exist for referring to measurements associated with a particular base last.
  • a scanning unit and a processing unit determine the measurements of a customer's feet and based on those measurements are operable to automatically adjust the elevation of the heel from a flat position. For example, if a customer chooses a shoe having a 90mm heel, but only data regarding a last having a 120mm heel is stored in an associated memory unit, the processing unit can develop the appropriate custom lasts .
  • the embodiments described above are illustrative examples of the present application and it should not be construed that the present application is limited to these particular embodiments. Various changes and modifications may be effected by one skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
