Abstract
A shoe (1) and a method for manufacturing a shoe are proposed, wherein the shoe has an upper part (11) which is connected to the sole (12) by means of a separable zipper (4) and is removable from the sole (12) by opening the zipper (4). In order to be able to manufacture the shoe (1) inexpensively and yet in a mechanically robust design, it is proposed that the zipper (4) be connected to the sole (12) by injection-molding the sole (12) onto a part of the zipper (4) or by injection-molding the sole (12) around a part of the zipper (4).
Claims18
A method for manufacturing a shoe, the shoe having an upper part which is connected to the sole a separable zipper and which can be removed from the sole by opening the zipper,
- comprising:
- connecting the zipper to the sole by one of the sole being injection-molded onto a part of the zipper, the sole being cast onto a part of the zipper, the sole being injection-molded around a part of the zipper, or the sole being cast around a part of the zipper.
A method for manufacturing a shoe, the shoe having an upper part which is connectable to the sole by means of a separable zipper and is removable from the sole by opening the zipper.
- comprising:
- providing a last having a circumferential groove on its lower circumference;
- and inserting a toothed bar of the zipper into the circumferential groove.
A method for manufacturing a shoe, wherein the shoe comprises an upper part which is connected to the sole by a separable zipper and which is removable from the sole by opening the zipper.
- comprising:
- using mold that comprises a sole bottom part and one or more side parts, the one or more side parts laterally delimiting the sole bottom part in order to form a sole chamber together with a last, and wherein at least one of the last or the one or more side parts has circumferential groove to receive a toothed bar of the zipper.
A construction kit for manufacturing a shoe comprising:
- at least one of (i) one or more shoe upper and at least two different soles or (ii) one or more sole and at least two different shoe uppers, wherein the shoe can be manufactured by connecting one of the shoe uppers to one of the soles a zipper.
