Abstract: A three-dimensional out sole having a pattern having improved quality and durability has a dye permeated into the surface of the outsole. A depth to which the dye penetrating the micropores is 0.08 mm to 0.12 mm. The dye is permeated into the microspores through vacuum suction. The dye is digitally printed on a thermoplastic sheet. The thermoplastic sheet on which the dye is printed is heated to be softened with flexibility. The softened sheet having flexibility is closely attached to a surface of the shoe outsole having the three-dimensional shape through vacuum adsorption and then is permeated therein.
