US Patent 11775697 Shoe design through 2.5-dimensional shoe models

Systems, methods, logic, and devices may support shoe design through 2.5-dimensional (2.5D) shoe models. In some examples, a system may include a 2D shoe shell pattern engine configured to access a 2D shoe shell pattern, the 2D shoe shell pattern generated for shoe design. The system may also include a 2.5D shoe model engine configured to generate a 2.5D shoe model by placing shoe design elements provided by a user onto the 2D shoe shell pattern of the shoe, including by adding 2.5D layering data for each shoe design element placed on the 2D shoe shell pattern to form the 2.5D shoe model, and wrap the 2.5D shoe model into a 3D shoe model for construction of a physical shoe from the 3D shoe model.
