Materials used in shoes have been widely developed according to the application conditions. Especially shoe sole is an important part to produce high-performance and prevent injuries. On the other hand, not only the development of new sole material but also adhesive technology and molding process of each individual part are so important in the shoes designing process. A shoe sole is consisted of many kinds of materials, for example, high abrasion rubber, EVA sponge and resin, etc. These parts are adhered with solvent adhesion manually. Therefore sole fabrication processes take much time and the qualities, such as adhesive strength and sole durability, are unstable.
In this few years, adhesive and molding methods have been developed with considering environmental issue. In this paper, the current technological aspects, material development, adhesive, molding technology and environmental issue are presented.
