Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.

Systems, methods, and computer-readable storage media for applying an adhesive film to the sole of shoes. Application of a portion of the adhesive film can be performed by receiving a shoe on top of the adhesive film, which in turn is above a plate and compressible pins. Upon receiving the shoe, the plate is raised or lowered, and the compressible pins mark the perimeter of the sole of the shoe. The adhesive film is cut in a sole-shaped pattern due to the height differentiation, resulting in a sole-shaped portion of the adhesive film being adhered to the sole of the shoe.

A tool path for treating a shoe upper may be generated to treat substantially only the surface of the shoe bounded by a bite line. The bite line may be defined to correspond to the junction of the shoe upper and a shoe bottom unit. Bite line data and three-dimensional profile data representing at least a portion of a surface of a shoe upper bounded by a bite line may be utilized in combination to generate a tool path for processing the surface of the upper, such as automated application of adhesive to the surface of a lasted upper bounded by a bite line.

Systems and methods are provided for collecting three-dimensional surface data of a lasted shoe upper that is mated with a sole that is configured for the lasted upper. The mated three-dimensional data is used with three-dimensional data of the lasted shoe upper in an unmated configuration with the sole to determine a location of an edge defined by the intersection of the lasted upper and the sole when mated. The bite line identifies an edge where the upper and a sole assembly will intersect on a finished shoe, which may represent a bounding line for application of adhesive to the lasted upper for boding the sole thereto.
