PURPOSE: To improve the taste and value of goods by forming a first coat layer and a second coat layer with a transparent coat on the surface of sole body contacting the ground, and forming a pattern display between both the layers.

CONSTITUTION: With respect to the surface, contacting the ground, of a sole material A formed based on a pattern-draw-molding process, etc., by use of a synthetic or natural rubber material, a paint to be used for synthetic and natural rubber, e.g., RB crape, is formed on a first coat layer 3 based on spray coating, etc. Next, on the surface of the layer 3, a pattern display 2 including required characters, figures, patterns and the like is formed through a screen printing. Finally, on the surface of the layer 3, a transparent paint used for synthetic and natural rubber, e.g., RB crape, is formed on a second coat layer 4 through spray coating, etc., to sandwich a pattern display 2 between both the layers 3, 4. Namely, the pattern display 2 part is maintained while being sandwiched by both the layers.
