Sole for sports shoes
Described are methods for manufacturing a sole, in particular, a sole for a sports shoe, comprising providing at least one first sole element and at least one second sole element; and injecting at least one second sole element through the at least one first sole element. Also described are methods for manufacturing a shoe, in particular a sport shoe, wherein the method comprising: providing a flexible sock element and at least one sole element; injecting the at least one sole element on the flexible sock element, such that the at least one sole element comprises a stiffening element below the arch of the foot.
1 . A sole comprising:
a flexible sock element having an upper region and a sole portion;
a reinforcing layer formed as an injected component positioned onto the sole portion of the flexible sock element;
at least one first sole element attached onto the reinforcing layer; and
at least one second sole element discrete from the reinforcing layer and formed as an injected piece extending through the at least one first sole element such that the at least one second sole element penetrates the at least one first sole element to provide a form-fitting connection between the at least one first sole element and the reinforcing layer, and the at least one second sole element extends through the at least one first sole element to the reinforcing layer to secure the at least one first sole element to the reinforcing layer;
wherein the reinforcing layer is arranged as a barrier to entirely separate the at least one second sole element from the flexible sock element.
2 . The sole according to claim 1 , wherein at least one of:
the at least one second sole element forms at least a portion of an outsole element; or
the at least one second sole element comprises a stiffening element located at a region below an arch of a foot.
3 . The sole according to claim 1 , wherein the sole is incorporated into a shoe, wherein the at least one second sole element injected through the at least one first sole element extends beyond a bottom periphery of the shoe and at least partially upward around at least a portion of an upper of the shoe.
4 . A shoe comprising the sole according to claim 1 .
5 . The sole of claim 1 , wherein at least one of:
at least a part of the at least one second sole element remains in the at least one first sole element; or
the at least one second sole element comprises at least one of the following synthetic materials: polyamide, polyether-block-amide, polyvinylchloride, polyurethane, and polyvinylchloride.
6 . The sole of claim 1 , wherein at least one of:
the at least one first sole element comprises a profile element or an aperture;
the flexible sock element comprises a textile;
the reinforcing layer comprises a Shore-A hardness of approximately 25 to 75; or
the at least one first sole element comprises a Shore-A hardness of approximately 55 to 95 and the at least one second sole element comprises a Shore-A hardness of approximately 70 to 90.
7 . The sole of claim 1 , wherein the at least one first sole element being attached onto the reinforcing layer comprises the at least one first sole element being injected or clipped onto the reinforcing layer.
8 . A sole comprising:
at least one first sole element;
at least one second sole element, wherein the at least one second sole element is injected through the at least one first sole element;
a flexible sock element; and
a reinforcing element injected onto the flexible sock element and discrete from the at least one second sole element;
wherein the at least one first sole element is clipped onto the reinforcing element;
wherein the first sole element being clipped onto the reinforcing element includes the first sole element being clipped by a mandrel of the first sole element being received in a notch in the reinforcing element; and
wherein the at least one second sole element is injected through the at least one first sole element such that the at least one second sole element penetrates the first sole element to provide a form-fitting connection between the first sole element and the second sole element and the at least one second sole element extends to the reinforcing element and secures the first sole element to the reinforcing element.
9 . A shoe comprising the sole according to claim 8 .
10 . The sole of claim 8 , wherein at least one of:
the at least one second sole element forms at least a portion of an outsole element;
at least a part of the at least one second sole element remains in the at least one first sole element; or
the at least one second sole element comprises at least one of the following synthetic materials: polyamide, polyether-block-amide, polyvinylchloride, polyurethane, and polyvinylchloride.
11 . The sole of claim 8 , wherein at least one of:
the at least one first sole element comprises a profile element or an aperture;
the flexible sock element comprises a textile;
the reinforcing element comprises a Shore-A hardness of approximately 25 to 75; or
the at least one first sole element comprises a Shore-A hardness of approximately 55 to 95 and the at least one second sole element comprises a Shore-A hardness of approximately 70 to 90.
