In a narrow sense, it only refers to the outsole. Generally, the common characteristics of sole materials should include wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy adaptation to foot shape, non deformability after shaping, thermal insulation, easy absorption of moisture, etc. At the same time, it is necessary to cooperate with the midsole to have a braking effect when changing feet during walking and avoid slipping and easy stopping. There are many types of materials used for shoe soles, which can be pided into natural and synthetic soles.
