The method as set forth in Description The present application relates to a system and method for creating a custom article and, more particularly, to a system and method for creating custom lasts used to make custom shoes. 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. Traditionally, shoe lasts were made of hardwoods, such as maple or beech. Modern day shoe lasts, however, are constructed of high-density plastics. Many styles of shoes can be made on the same shoe last, but the toe shape and heel height will be the same for each pair of shoes made on that shoe last. 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. One known method of making custom shoes for a person involves scanning the person's feet. Based on the results of the scan, a previously manufactured shoe last is manually modified and thus created for each foot of the particular person. In particular, the previously manufactured lasts can be modified, for instance, by sanding or by adding man-made materials to the lasts. Alternatively, the shoe lasts can be made by first creating molds of a person's feet using putty or a plaster cast. From these molds, lasts are made in either plastic or wood. To further refine the lasts or change the toe shapes the lasts would be either sanded down or increased using man-made materials. Another known method for making custom shoes involves the use of previously manufactured lasts and manually measuring a person's foot using a tape measurer. Similar to the above-described known method for making custom shoes, man-made materials are then used to improve and reshape manufactured lasts to the required measurements. When another person desires a pair of custom shoes, however, one of the above-processes for producing the respective lasts is repeated. A need exists for refining the system and method for manufacturing custom shoe lasts. For instance, there is a need to develop custom shoe lasts from template lasts and associated test shoes that have previously been confirmed by an individual as having a proper fit. There is also a need to calculate shoe last measurements in smaller increments such as millimeters. Additional needs are addressed by the exemplary embodiments of the present application. An aspect of the present application provides for a method for developing lasts. The method comprises developing a last and a test shoe from the last for an individual, the test shoe meeting at least one predetermined criteria based on feedback from the individual, determining at least one measurement of the developed last, storing the at least one measurement, developing another last for another individual by modifying the stored at least one measurement. Another aspect of the present invention provides for a method for developing lasts. The method comprises developing a last and a test shoe from the last for an individual, determining at least one measurement of the developed last, storing the at least one measurement, and developing a plurality of lasts for a plurality of respective other individuals by referring to the stored at least one measurement. A further aspect of the present application provides for a method for developing custom lasts. The method comprises developing a pair of template lasts for an individual, developing a pair of test shoes meeting at least one predetermined criteria from the pair of template lasts, measuring feet of the individual to determine a first plurality of measurements, measuring feet of a customer to produce a second plurality of measurements, comparing the first plurality of measurements and the second plurality of measurements to determine at least one adjustment measurement, and developing a pair of custom lasts by modifying the pair of template lasts according to the at least one adjustment measurement. A still further aspect of the present application provides for a method for developing a pair of custom shoes for a customer. The method comprises (a) determining a first plurality of measurements by measuring a base last, (b) storing the first plurality of measurements, (c) determining a second plurality of measurements by measuring at least one foot of an individual, (d) storing the second plurality of measurements, (e) developing a pair of template lasts, (f) developing a pair of test shoes from the pair of template lasts, the test shoe meeting at least one predetermined criteria based on feedback from the individual, (g) storing a third plurality of measurements associated with the pair of template lasts,(i) determining a fourth plurality of measurements by measuring a left foot and a right foot of a customer, (j) storing the fourth plurality of measurements, (k) determining a plurality of adjustment measurements by comparing the second plurality of measurements to the fourth plurality of measurements, (1) developing a pair of custom lasts associated with the customer according to the plurality of adjustment measurements by modifying either the base last or the pair of template lasts, and (m) developing the pair of custom shoes from the pair of custom lasts. According to the exemplary embodiments described in the present application, custom lasts and custom shoes are manufactured for a customer. Specifically, the customer can select, for example, any style, color, fabric and heel size/type for a pair of shoes, and since exemplary customer shoe development system Main facility Remote facility Scanning unit The components of In an exemplary embodiment, a base last is referred to when developing template lasts and, more particularly, the measurements associated with the base last. The base last, or a plurality of base lasts, can be selected, designed and/or developed by, for example, a designer and/or a shoe last manufacturer working together or alone on the end shape. Each base last corresponds to a particular shoe size and has its own style which determines the heel height and toe shape. The exemplary embodiments of the present application, however, are described with reference to the women's size 38 base last As depicted in The base last measurements determined by scanning unit In order to develop one or more template lasts from a respective base last that can be used by system The individual's left foot and/or right foot are scanned by scanning unit The timing associated with determining and storing the individual's measurements is not meant to be limited to after determining and storing base last measurements in Once the individual has been selected, one or more pairs of test shoes are developed from base last Based on the size of the individual's feet, determined either by asking the individual, manually measuring the feet or foot of the individual, electronically measuring the individual's feet or foot or the like, a base last is selected from the existing size run that has the closet measurements to the individual's feet or foot. For instance, size 38 base last The pair of test shoes are then tested by the individual, for instance, to determine whether at least one predetermined criteria is satisfied in In an exemplary embodiment, a shoe is balanced when there is an equilibrium of measurements. For instance, for a shoe to be balanced, the distance from the toe of the shoe to the widest measurement needs to be correct, the distance from the widest measurement to the heel of the shoe needs to be correct and the relation between the height of the heel of the shoe to the length of the shoe needs to be correct. If the shoe heel is too high or too short for the length of the shoe, then walking is quite difficult if not impossible. If the proportion of the toe-width measurement is too short or too long, then the arch of the foot is either pushed up or the foot slides too far forward making walking uncomfortable. If the width of the shoe and the heel are not aligned correctly, a foot will turn in or out. Improper balance can be determined in a variety of ways. For example, by feedback from the individual, by visually observing tension in the feet of the individual and the area around the individual's ankles, and/or by visually observing the wearing of the soles of the test shoes. Electronic sensors can also be used to determine tension in the feet of the individual and the area around the individual's ankles. If the test shoes are confirmed to be a proper fit in In particular, according to the feedback obtained from the individual by answering one or more of the above-enumerated questions, at least one adjustment is made to the base last measurements for the left foot and/or the base last measurements for the right foot. Data regarding any adjustments is then transmitted by processing unit In an exemplary embodiment, at least one of the following five adjustments are made by last manufacturer Last manufacturer In an exemplary embodiment of the present application, multiple template lasts can be manufactured as described herein, each template last being associated with a different shoe style, i.e., heel size and toe style. These multiple template lasts, however, are developed using the same individual or different individuals each having the same size feet, for instance, size 38. Accordingly, depending on the custom shoe selected by a customer, the respective template last or base last is referenced for manufacturing the appropriate custom last. Alternatively, multiple template lasts are developed from different individuals having different feet sizes. As a result, depending on the custom shoe selected by a customer and the size of the customer's feet, the respective template last or base last having the closest size is referenced for manufacturing the appropriate custom last. Because a customer can select a pair of custom shoes having a particular heel pitch and heel height, as described below, a template last will have already been made, i.e., a base last will have already been modified accordingly, as described above, to accommodate that heel pitch and heel height. Heel pitch refers to the angle of the heel in relation to the last. In an exemplary embodiment, the following is taken in consideration when developing each template last and the associated test shoe, for example: as a foot rises due to heel height, the distance between the ball of the foot and the heel shortens; a foot needs different support as the heel rises; and in general, a higher heel shoe is narrower at the toe than a flat shoe. Besides the shoe style and heel height, the customer also has the ability to select the fabric, the color of the fabric, if applicable, accessory details, shoe back or strap and/or embroidery or the like. In an exemplary embodiment, the customer has the ability to select any available shoe style and the desired heel height for that shoe style from a group of available heel heights. For instance, if a customer wants the custom shoe shown in Before or after the customer selected the shoe shown in The customer measurements are transmitted by processing unit The data indicating the customer's measurements and selected custom shoe Since the same or similar measurements were taken for the individual's test feet and the customer's feet, the results of one or more of the following measurements are compared, in Upon the adjustment measurements being determined by processing unit Each pair of custom lasts are assigned a unique last identifier. For example, 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 Such information is later used in order to retrieve custom lasts associated with a particular customer. This data is stored in the customer's personal data file or in association therewith in memory unit The physical custom lasts In an alternative embodiment of the present application, scanning unit 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. Referenced by
