Abstract
A method of manufacturing a sole assembly includes using a jig with a first mold assembly to distribute pellets a first material into a recess of a first mold member of the first mold assembly. A second material is injected into the first mold assembly, and the first mold assembly is heated to form a first preform. The first preform and a second preform are heated in a second mold assembly to form a sole assembly with a camouflage appearance around only a periphery of the sole assembly.
