PURPOSE: A surface treatment composition is provided to improve durability and lifetime of a product and an excellent adhesive force between the injection parts and injection-molded mid sole. CONSTITUTION: A surface treatment composition comprises: 0.2-3 parts by weight of adhesion accelerator, and 1800-4000 parts by weight of solvent base on 100.0 parts by weight of base material. The base material comprises: 75-95 weight% of chlorinated ethylene vinyl acetate graft polymer, and 5-25 weight% of chlorinated ethylene vinyl acetate resin. The chlorinated ethylene vinyl acetate graft polymer is comprised by graft polymerizing 50-100.0 parts by weight of nonfunctional acrylic monomer base on the 100.0 parts by weight of chlorinated ethylene vinyl acetate resin which has 26-28 weight% of chlorination rate.
