Sole material

There are mainly hard leather, soft leather, imitation leather, cloth, rubber, plastic, rubber-plastic and rubber-plastic foam materials. Hard leather is processed from cattle and pig skins, and is mostly used for leather shoes, and a small amount is used to make leather-soled cloth shoes. In addition, leather shoes are also widely used imitation leather soles. Cloth is the main material of traditional cloth soles. The old cloth is used as the raw material to be processed into a jacket or a bottom blank, and the hemp rope is used to form a thousand-layer bottom or a wool bottom by hand or machine. The plastic is mainly polyvinyl chloride resin, which is mostly used for plastic shoes and cloth shoes. Rubber has natural rubber and synthetic rubber, used for rubber shoes and cloth shoes. There are two kinds of soft leather, artificial leather and natural leather, which are mostly used for cloth slippers and soft-soled cloth shoes. Rubber-plastic and rubber-plastic foam materials are mostly used for leather shoes and cloth shoes.
