Cheng Chang, through its China based subsidiary Jinjiang Cheng Chang Shoes Co., Ltd., engages in the business of designing, producing and selling high quality shoe soles used to manufacture athletic and leisure shoes. Cheng Chang categorizes its sole products into three primary product lines: (i) EVA, or ethylene vinyl acetate, sole products which are made from a viscous and elastic foam material that contains tiny bubbles which provide good shock absorption and cushioning abilities; (ii) RB, or synthetic rubber, sole products processed mainly from polybutadiene rubber, which is highly resistant to wear and abrasion and used mostly commonly in the production of outsoles; and (iii) EVO, or EVA outsole, products which are an outgrowth of its EVA product line that is designed to be more abrasive resistance and lighter and softer than its EVA product line.
