The construction of shoes with a wound sole having a foam midsole is generally known. In the manufacture of this type of shoe, the foam that has been conventionally foam-molded is punched and cut into a midsole shape, and this is attached to the grounded sole with the rolled-up portion (extension) on the toe to form the shoe sole. Since the shoe sole is adhered to the bottom of the cover by the adhesive method and the winding portion is wound and adhered to the toe of the cover, the manufacturing process is complicated and the cost is significantly increased.

からなる外観良好な靴底が得られる。In this invention, a thin burr 43 is formed integrally with the grounded bottom 4 on the upper peripheral portion of the vulcanized rubber grounding bottom 4, and when the vulcanized rubber grounding bottom 4 is set on the bottom mold 5, the thin burr 43 is formed on the upper peripheral portion of the bottom mold 5. Set by inserting into the formed groove 51, 2
If the lower surfaces of the side molds 3 and 3 are pressed against each other when forming the next mold cavity 0 ', the midsole molding material may enter the side surface of the grounding bottom 4 or the grounding surface side when foaming the midsole 6. There is no. Moreover, this burr 43
After molding the midsole 6 and removing it with a knife, a grinder or the like, a shoe sole composed of a laminated body of the midsole 6 and the grounding sole 4 can be obtained.
