The primary manufacturing process for the shoes is casting because the switch is made of plastic and the globe is made of resin, which are suited for casting. The secondary process is drilling to fix the electrical circuit to the sole. The tertiary process is joining and painting - joining to connect the wire and assemble to the sole, and painting to make the shoes trendy. The material and manufacturing processes are compatible with the product geometry. The electrical circuit size suits the sole base and shoes can be different sizes. The material can withstand the normal load of a person's foot weight and be kept away from direct sunlight or water.
