[0158] In the depicted stage of the assembly process, at least the TPU element T1 is (not yet) joined together with TPU element T2?.
[0159]
[0160] In particular,
[0161]
[0162] Notably,
[0163] More specifically, the first upper element 7 may be provided with a TPU element 21 which may be in the shape of a skeleton of the first upper element 7.
[0164] Additionally, or alternatively, it may also be possible that the first upper element 7 is provided with a mesh element 22. The mesh element 22 may advantageously provide the first upper element 7 with increased breathability and wearing comfort (as the mesh element 22 may act as a cushioning element against, e.g., eyelet 11 (not shown in
[0165] Additionally, or alternatively, it may also be possible that the first upper element 7 is provided with a synthetic suede and/or a hot melt, for example, cooper II flex layer 23 (to support bonding). In particular, the usage of synthetic suede may provide the respective portions of the first upper element 7 (at which the suede is located) with additionally stability, e.g., with respect to tear strength, abrasion resistance, etc. In some cases, synthetic suede may also be used for increased thermal insulation such that a hypothermic state of the foot of the wearer may be avoided. In some cases, synthetic suede may also be used as an optical distinction element of the first upper element 7, e.g., due to its color and/or material appearance.
[0166]
[0167] In some cases, the first upper element 7 may be provided with a contour element 24 which may preferably be provided in the shape of the contour (outer circumferential shape) of the first upper element 7. The contour element 24 may be an integrally formed piece or may be composed of one or more separate parts. The contour element 24 may be provided in a single color.
[0168] In some cases, the first upper element 7 may alternatively or additionally be provided with a contour element 25 which is provided in more than one color which may match the respective colors of the first upper element 7 in regions in which the contour element 25 may joined together with the first upper element 7.
[0169] Contour elements 24 and 25 may be made from TPU, a plastic material and/or any other suitable material.
[0170]
[0171]
[0172] The second upper element 8 may additionally be provided with TPU element 26 (right hand-side of
[0173] The TPU element 26 is provided in a shape to match the contour of the second upper element 8. The TPU element 26 preferably extends from the edge 27 of the second upper element 8 towards the center 28 of the second upper element 8, preferably for not more than 15 mm.
[0174]
[0175]
[0176] Similar to the first upper element 7, also the second upper element 8 may be provided with a respective contour element 29 which may be provided in the shape of an outer contour of the second upper element 8. Besides from the shape of the contour element 29, the contour element 29 may be implemented identical to the contour elements 24 or 25 as described with reference to
[0177]
[0178]
[0179] It may be possible that rubber element 30a is exclusively used for joining together the first upper element 7 and the second upper element 8 or that the rubber element 30a is used in addition to a sewing/stitching procedure for joining together the first upper element 7 and the second upper element 8 such as to, e.g., reinforce the stitching, to provide the shoe upper 1 with an optical distinction and/or to protect the stitching against potential abrasion.
[0180]
[0181] In the exemplary case, shoe upper 1 is placed in a heat press 31. At least the rubber element 30a (shown adjacent to the shoe upper 1 in

[0199] Heel blinker 33 may then be joined together with the shoe upper 1 by moving the heat press 31 downwards onto the heel area 4 of the shoe upper 1 to heat press the respective parts in the heel area 4.
[0200] In a subsequent step (
[0201] This process may further be used to ensure a curved heel area 4. The process of curving the heel area 4 may be understood as a two-step process: in a first step, the heating process, the material used to form the heel area 4 may be made soft and malleable as a result of the applied heat. A subsequent second step, a cold step, may then be applied to fix the final curved shape of the heel area 4.
[0202]
[0203]
[0204] In some cases, the shoe upper 1, according to this embodiment, may be provided such that the bottom face of the second upper element 37, which may be in contact with an asphalt during wearing of the shoe upper 1, may be provided such that no additional (outer) sole is required (left hand-side of
[0205] The heel area 4 of the shoe upper 1 is further provided, in the depicted exemplary embodiment, by a heel element 39 which is wrapped around the heel area 4 from a lateral side of the shoe upper 1 to a medial side of the shoe upper 1. The heel area 4 may be used to provide the shoe upper 1 with additional dimensional stability. More specifically, the heel element 39 at least partially fulfill the task of a conventionally used heel counter and may at least contribute to a stiffening of the heel area 4. This may minimize a heel movement during running (in particular, during the phases of landing and push-off) and may thus advantageously contribute to the stability of the foot of the wearer when wearing the shoe (upper). A further side-effect of heel element 39 may be seen in a further weight reduction of the shoe upper (e.g., as compared to a potential usage of a conventional heel counter).
