Abstract

Systems and methods for generating three-dimensional design lasts for footwear include: (a) generating a three-dimensional last structure on a computer display (e.g., having the appearance of a conventional footwear last structure); (b) receiving user input indicating offset values for various zones of the last structure, wherein the user input indicates offset values for one or more of: a toe region, a heel region, an ankle region, a forefoot region, and/or an instep region; and (c) generating a three-dimensional design last for the footwear on the computer based on the three-dimensional last structure and the user input indicating the desired offset values. The three-dimensional design last may constitute a modified version of the three-dimensional last structure that has an increased thickness to simulate a desired thickness of an upper material placed on the last structure and/or to more closely simulate an appearance of an actual footwear upper.

Description

Technical field [0001] The present invention mainly relates to a computer-generated three-dimensional design last for designing footwear. Background technique [0002] Many footwear products are manufactured using "shoe lasts", which are physical elements that help provide the shape of upper components in the manufacturing process. Although the shoe last can provide a sufficient foundation for actual manufacturing, it must fit in the shoe upper and must be able to be removed from the combined shoe upper, so the shoe last has a shape somewhat different from the upper. For example, the shoe last must be somewhat smaller than the shoe upper so that the shoe last can be placed in and removed from the shoe upper. In addition, compared to the final upper structure produced thereon, the last structure usually has a significantly smaller ankle opening area and a significantly narrower ankle structure overall. In addition, the last structure usually has a steeper tongue or instep area com...
