Sport footwear with decorative surface structure

摘要

The part of a sport shoe whose wall comprising an external layer made of transparent or translucent plastic material, comprises inner surface portion not directly contact with the external layer having a visible surface, and two parts combined on two separate surface layers from the wall of the shoe to form a deep effect. The wall comprises two layers superimposed on plastic materials. The visible surface is structured on a part of the inner surface through the external layer. The surface structure consists of few hundreds of millimeter and few tenths of the thickness of the layer. The part of a sport shoe whose wall comprising an external layer made of transparent or translucent plastic material, comprises inner surface portion not directly contact with the external layer having a visible surface, and two parts combined on two separate surface layers from the wall of the shoe to form a deep effect. The wall comprises two layers superimposed on plastic materials. The visible surface is structured on a part of the inner surface through the external layer. The surface structure consists of few hundreds of millimeter and few tenths of the thickness of the layer. The inner layer is also transparent or translucent and directed on the side of the foot or shoe of a user. Another surface has ribs and/or grooves combined with the surface structure and juxtaposed on the same surface and/or combined on a separate surface. The surface structure forms a design around the surface state, and forms a decoration having a rough surface surrounded by a smooth surface or vice versa. Independent claims are included for: (1) a ski boot; and (2) a process for fabricating the part of the sport shoe.
