ABSTRACT:
Systems and methods for generating three-dimensional design lasts for footwear include: (a) generating a three-dimensional last structure on the 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.
