Abstract:
A method of determining a fit of footwear, comprising the steps of:a. inserting over an insole of the footwear, a removable insert having a length and width which correspond to the length and width of the footwear, said insert comprising a thermally sensitive layer applied to a top surface of at least one supporting layer, the top surface providing indicia to indicate a maximum recommended foot size in the footwear, b. inserting a foot into the footwear, whereby when in contact with the foot the thermally sensitive layer changes color to produce an image of the user's footprint, and c. removing the insert from the footwear to visually inspect the image and determine whether the image is larger than the indicia whereby if the image is larger than the indicia, then the footwear does not have the proper fit for the foot.
