Furthermore, forming the adhesive body 3 with the metal particles 2 in each recess 101 requires a large amount of labor, consumes time and increases costs. This is because forming the adhesive body 3 with the metal particles 2 fills each recess 101 with the adhesive body 3 and
The metal particles 2 are introduced into the inside, the adhesive body 3 is pressed in each recess 101, and the burr of the adhesive body 3 in each recess 101 is removed. This is because it is necessary to wait for drying. In addition, product quality is not constant due to human errors that occur during sole manufacturing. In addition, the flexibility of the adhesive body 3 is usually inferior to the flexibility of the rubber body 4.
