1. A method of manufacturing a structure for permanent attachment to a base component of an article of apparel, comprising:
- associating a first nozzle with the base component, the first nozzle having a first aperture size;
forming an outer shell portion of the structure on the base component by extruding a first material through the first nozzle, wherein the outer shell portion is formed with at least one opening providing access to an interior of the outer shell portion;
removing the first nozzle from an area near the outer shell portion;
associating a second nozzle having a second aperture size with the at least one opening, wherein the second aperture size is greater than the first aperture size; and
extruding a second material through the second nozzle and into the at least one opening, thereby forming an inner portion of the structure.
