A heel blinker 33 may be used to provide the shoe upper 1 with additional stability in the heel area 4 of the shoe upper 1 and/or for optical distinction.

[0194] FIG. 8A shows an exemplary embodiment of the heel blinker 33, which, in a preferable embodiment, may be made from a synthetic suede element 33a. In a preferred embodiment, and as depicted in FIG. 9A, the heel blinker 33 may additionally be provided with a cooper II flex element 33b.

[0195] FIG. 8B shows an exemplary assembly step how the heel blinker 33 may be inserted into the shoe upper 1. In FIG. 8B, heel blinker 33 is formed into a curved shape and then inserted into the shoe upper 1 (through a throat opening 34). Heel blinker 33 may preferably inserted into the shoe upper 1 such that at least a portion of the synthetic suede element 32a is protruding out of the throat opening 34 the shoe upper 1 at the heel area 4.

[0196] FIG. 8C shows a view into the shoe upper 1 and along the longitudinal axis of the shoe upper 1 onto the heel blinker 33, after the heel blinker 33 has been inserted into the shoe upper 1.

[0197] FIG. 8C further shows the inner surface 35 of the shoe upper 1 which, in FIG. 8C, is made from a mesh material and which corresponds to an upper face of the second upper element 8.

[0198] FIG. 8D shows an exemplary assembly step how the heel blinker 33 may be joined together with the shoe upper 1, preferably by heat pressing. FIG. 8D (left hand-side) shows an exemplary heat press 31 which may be adapted to receive the heal area 4 of the shoe upper 1 by means of a shoe upper holding structure 35.

[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 (FIG. 8D, right hand-side), force applying element 36 may engage with the heel area 4 of the shoe upper 1.

[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] FIGS. 9A-9D show another exemplary embodiment of the shoe upper 1.

[0203] FIG. 9A shows an illustration of an exemplary shoe (comprising the shoe upper 1 formed by the first upper element 38 and the second upper element 37) according to the embodiment as seen from a medial point of view (left hand-side) and as seen from a top-view (right hand-side).

[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 FIG. 9A). Alternatively, the shoe may comprise the shoe upper 1 and bottom face 2 attached thereto (right hand-side of FIG. 9A). The former implementation may support a further weight reduction and may thus facilitate a light-weight shoe whereas the latter may provide additional cushioning and thus increased prevention against injuries of the joints of the athlete.

[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).

[0206] FIGS. 9B and 9C show a detailed view onto the heel element 39 as seen from the front (FIG. 9B) and as seen from the back (FIG. 9C).

[0207] FIG. 9D shows a further illustration of the shoe upper 1 as seen in a skewed elevated view from the heel area 4 of the shoe upper 1. The illustration depicts a view into the throat 34 of the shoe upper 1 towards the toe area 3 of the shoe upper 1.
