PURPOSE:To prevent a primary main sole from adhering to a dummy mold lower surface by providing an undercut part 11 on the side circumference surface of a projection projected in the necessary part of the upper surface of a sole mold at the time of manufacturing an injection formed footwear to be punched twice through the use of the dummy mold. CONSTITUTION:At the time of manufacturing the injection formed footwear to be punched twice through the use of a dummy mold 1, the undercut part 11 is provided on the side circumference surface of a projection 10 projected in the necessary part of the upper surface of a sole mold 3. As a result, the injection formed footwear can be obtained in which a dislocation and a floating after a part or the whole part of the upper surface of a primary main sole 5 adheres to the lower surface of the dummy mold cannot be generated and which has desired two layers on the side circumference surface of the main sole even by the injection forming of a secondary main sole. |
