Abstract
A molding system for direct injection manufacturing of footwear. The molding system includes a mold cavity for receiving injection material for molding a sole part of the footwear. The system further includes a plurality of basic direct injection molds, each of which is attachable to injection molding equipment, and a plurality of sets of direct injection mold inserts, each set of direct injection mold inserts being configured to define at least part of an inner surface of the mold cavity when inserted in one of the plurality of basic direct injection molds. At least two of the plurality of basic direct injection molds differ from each other in size, corresponding to different ranges of sole part sizes.
