PROBLEM TO BE SOLVED: To provide a completely waterproof mechanism and ensure the elastic buffer property and the grounding reaction by clamping a metal block screwed to a molding extracted from a mold and an antislip spike brought into contact with the sole face of shoes. SOLUTION: A pin 10 is inserted into a pin inserting hole in a plate 11 for attaching a metal block, and a hard polyvinyl chloride is poured and the plate 11 is embedded into a hard polyvinyl chloride resin layer 23. A molding is extracted from a mold 8, and an antislip spike 14 with a claw part 14 which can be freely replicated in the longitudinal direction of the shoes, is screwed 16 into the metal block 9 consisting of the molding and the plate 11 for the metal block 9, into which the pin 10 is inserted. In addition, the metal block 9 and the antislip spike 14 are interrelatively clamped and firmly fixed to the heel part 5 of a tighly mounted shoe sole part 7. |
