The invention provides a method for forming a foamed shoe sole. The method essentially comprises slowly injecting a foaming material into a forming mold to prepare an unfoamed blank, controlling the quality of the blank thereby recycling defectives, mounting the qualified blank into a thermal press foaming mold to complete the foaming and molding. The above two-stage production process with delayed foaming can ensure that the product has no defects such as insufficient material, yellowing, etc. Furthermore, the product has a uniform density, a good skin; and the material can be recycled thereby reducing the production cost.
