Three-dimensional out sole having improved pattern quality and durability, and shoe comprising same

A method of manufacturing an outsole of a three-dimensional shape with improved pattern quality and durability, the method comprising:

• printing a pattern on a sheet formed of a thermoplastic resin using a dye;
• placing the sheet on the outsole and softening the sheet using a heating device;
• vacuum-suctioning the outsole of the softened sheet, which includes primarily vacuum-suctioning the outsole of the softened sheet and secondarily vacuum-suctioning the outsole of the softened sheet;
• and
• fixing a pattern on the outsole at a high temperature with the dye permeated to micropores on a surface of the outsole,
• wherein the primarily vacuum-suctioning the outsole of the softened sheet includes slowly attaching the softened sheet to the surface of the outsole with a low vacuum pressure, and
• wherein in the secondarily vacuum-suctioning the outsole of the softened sheet, the dye is permeated into the micropores inside the surface of the outsole with a high vacuum pressure.
