    摘要: A plastic shoe has a steel cap (3) which has a cushion (4) in the upper region inside the shoe. In its other regions the steel cap (3) is surrounded on the inside and outside by plastic foam which forms the upper (1) and the bottom (2) of the plastic shoe (2). The cushion (4) consists of an air-absorbing material, so that the air displaced under the cap during the foam-filling of the mold does not lead to voids in the plastic.
