PROBLEM TO BE SOLVED: To provide a manufacturing method of an integrated sole which a strap can be quickly assembled to and replaced. SOLUTION: An assembled block 40 and a cushioning block 24 are equipped in a solid protrusion 22 and recess grooves 23, 12 in upper and lower dies 20, 10. After the upper and lower dies 20, 10 are closed, a foaming material is injected to coat the assembled block 40 in the upper and lower dies 20, 10 and the dies 20, 10. Then, the upper and lower dies 20, 10 are opened to form a sole 30 into which the assembled block 40 and the cushioning block 20 are buried and which exposes an inserting hole 43 of the assembled block 40 at the surface of the sole 30. |
