摘要： A process of making a sole includes mixing a foaming material with a nucleating agent to form a plurality of local blanks belonging to different portions of a sole wherein the local blanks belonging to different portions have different ratios of the nucleating agent; injection molding the local blanks to form a plurality of cold molds which are joined together along a horizontal direction to form a sole blank; sulfurizing the sole blank; and subjecting the sole blank to supercritical foaming to produce a finished sole.
