PURPOSE: A method for fabricating a shoe sole is provided to represent various colors in the shoe sole by a simple manner. CONSTITUTION: A foamed material having different colors is cut in a uniform size and mixed with each other in a predetermined ratio. A predetermined amount of the mixed material is injected into a mold. Then, heat is applied to the mixed material so as to melt the mixed material. When the mold is filled up with the molten material, the molten material is foamed so that a shoe sole having various colors is obtained. Various patterns are naturally formed in the shoe sole. The foaming process is carried out by using a vacuum foaming device so that the fault rate is remarkably reduced. In addition, a post-treating process is not required. Since the manufacturing process of the shoe sole is simple, the productivity thereof is increased.
