The invention discloses a method for treating the surfaces of shoes, comprising the following steps: putting the shoes in a vacuum cavity, and subjecting the shoes to low-temperature plasma discharge treatment in the working gas environment, wherein the vacuum degree in the vacuum cavity is 0.01-2,000 Pa, and the temperature of the surfaces of the shoes is 30-200 DEG C. According to the method, active groups are generated on the surfaces of the shoes, so that the water treatment process used currently is replaced, and the adhering strength of the shoes and the adhesive is improved.
