Abstract: The invention relates to a method of processing a sheet material for use in the manufacture of a product. The method comprises providing a sheet material having a first surface and a second surface; providing a two-dimensional mark on the first surface of the sheet material; arranging one or more strengthening members at one or more of the first surface and the second surface of the sheet material; imposing an indentation on said first surface of the sheet material; wherein at least part of the indentation is arranged with respect to one or more of at least part of the two-dimensional mark and at least part of the one or more strengthening members to create a three-dimensional mark on said first surface. The invention also relates to a blank for at least part of a manufactured product.

Abstract: A method of processing a sheet material (20) for use in the manufacture of products such as, but not limited to, a shoe upper blank (10). The method comprises providing a sheet material (20); providing a two-dimensional mark (30) on a surface of the sheet material (20); imposing an indentation (40) on said surface of the sheet material (20), wherein at least part of the indentation (40) is arranged with respect to at least part of the two-dimensional mark (30) to create a three-dimensional mark (50) on said surface. A blank for such a product is also related. The blank (10) comprises a sheet material (20) shaped in accordance with the product such as a shoe upper, the sheet material (20) comprising a two-dimensional mark (30) is provided thereon and is positioned with respect to an indentation (40) formed in the sheet material (20) to thereby provide a three-dimensional mark (50) on said surface.

Abstract: The invention relates to a self-assembled shoe and a method of manufacturing thereof. The self-assembled shoe comprises one or more locking systems for connecting a shoe base with one or more shoe components. The locking system is manually releasable upon actuation by a user at an actuating portion of the shoe base, and is substantially covered from view from an exterior of the shoe when assembled. The locking system further comprises an actuator arranged to be in direct contact with a medium of shoe base at the actuating portion, such that actuation at the actuating portion of the shoe base is directly transmissible through the shoe base medium to the actuator of the locking system to thereby actuate the locking system. The invention also relates to a covering member adapted to substantially cover one or more recesses defined by a female locking member of the locking system for the self-assembled shoe as described above.
