DETAILED DESCRIPTION OF THE INVENTION
[0052] FIG. 1 shows a running shoe 1 according to the invention with a heel area FB, a forefoot area VB and a midfoot area MB. The skilled person understands that the arrows indicate the area boundaries by way of example and do not define sharp area boundaries. According to the coordinate system, the longitudinal direction denotes the running direction of the shoe, i.e., the y-direction. The vertical direction is described by the z-direction. The latitudinal direction is described by the x, or −x direction. The running shoe 1 further comprises a shoe tip 4 and a heel edge 5. Furthermore, the running shoe comprises a shoe sole 3 and an upper 2, wherein the upper 2 comprises a textile base material. In addition, the running shoe comprises a group of pulling straps including a first pulling strap 15 and a second pulling strap 16. The pulling straps 15 and 16 are longitudinally stretchable and exert a pulling force on the upper and the textile base material. In the worn state, the pulling straps 15 and 16 are stretched and, by forming a pulling force against the pronation of the foot, cause the pronation angular velocity to be reduced during walking, thereby increasing the cushioning effect. This effect is further enhanced by the fact that the pulling straps 15 and 16 are each directly connected to the sole of the shoe. In addition, the pulling straps prevent the wearer's foot from partially slipping beyond the periphery of the shoe sole 3. As can be seen in FIG. 1, the second pulling strap 16 extends vertically from the shoe sole on the medial side, i.e., rising in the z-direction, toward the first pulling strap 15, thereby forming a substantially triangular third functional zone 23. The third functional zone is pre-stretched both in the longitudinal direction, i.e., in the y-direction, and in the latitudinal direction, i.e., perpendicular to the longitudinal direction and extending from the medial side to the lateral side across the foot of the wearer in the x-direction. This allows a comfortable fit for different hallux shapes and hallux sizes without feeling uncomfortable pressure on the hallux when walking.
[0053] The first pulling strap 15 divides the forefoot area VB into a first functional zone 21 and a second functional zone 22. As shown in FIG. 1, the first functional zone 21 extends from the shoe tip 4 to the first pulling strap 15. The second functional zone 22 is delimited on one hand by the first and second pulling straps 15 and 16, and on the other hand by the first tension strap 11. The first tension strap 11 extends from the medial side of the shoe sole 3 to the lateral side of the shoe sole 3 and is located in the midfoot area. As shown in FIG. 1, the first tension strap 11 extends generally in front of the entry opening of the running shoe 1 as seen from the shoe tip 4. When worn, the first tension strap 11 extends over a LONE of the wearer's foot and causes an inwardly directed compression force, i.e., directed toward the foot, whereby the foot is stabilized and held laterally, i.e., in the x and −x directions, on the one hand, and stabilized and held vertically, i.e., in the z direction, on the other hand. The first tension strap 11 also defines a fourth functional zone 24 of the upper 2, which is arranged behind the first tension strap 11 as seen from the shoe tip 4 and extends from there to the heel edge 5.
[0054] Furthermore, the running shoe 1 shown in FIG. 1 comprises second tension strap 12, which runs on the medial side in the heel area FB and extends vertically ascending from the running shoe sole 3 at the heel edge 5 to the first tension strap 11. Generally, a plurality of tension and/or pulling straps may cross, contact or merge with each other. The second tension strap 12 surrounds the wearer's foot from the heel edge over the medial side. Thus, the foot is stabilized in the x-direction. In addition, the compression force exerted on the foot by the tension strap 12 ensures a good hold of the running shoe on the foot. The group of tension straps of the running shoe 1 shown in FIG. 1 also includes a fourth tension strap 14, which in particular ensures a good hold of the rear heel part in the region of the Achilles tendon. The fourth tension strap 14 extends from the medial side of the shoe sole 3 over the heel edge 5 to the lateral side of the shoe sole 3. Moreover, the fourth tension strap 14 rises vertically in the direction of the heel edge, i.e. in the z-direction, and reaches its maximum height in the z-direction at the heel edge 5. The first, second, third (not shown in FIG. 1, see FIG. 2) and fourth tension straps (11-14) define a fifth functional zone 25 which is pre-tensioned in the longitudinal and latitudinal direction. The fifth functional zone 25 is thus located in the region of the entry opening of the running shoe and thus compresses the upper part of the running shoe in the worn state in the region of the ankles.
[0055] FIG. 2 shows the embodiment of the running shoe 1 as a top view on the lateral side. It can be seen that the pulling strap 15 runs obliquely from the engagement point on the medial side to the lateral side at an angle in the direction of the heel area FB. Thus, the engagement point on the lateral side is shifted further towards the heel edge 5 than the engagement point on the medial side. In addition to the first, second and fourth tension straps, the running shoe 1 has a third tension strap 13 which runs on the lateral side in the heel area FB and extends in a vertically ascending manner from the running shoe sole at the heel edge 5 to the first tension strap 11. Equivalent to the second tension strap 12, the tension strap 13 rises continuously in the vertical direction and finally runs horizontally, i.e. in the y-direction. The compressing tension straps 11 to 14 thus exert an inwardly directed force on the wearer's foot essentially from all sides, as a result of which the running shoe is held firmly on the foot.
[0056] FIG. 3 shows a further embodiment of the running shoe 1. In contrast to the running shoe from FIGS. 1 and 2, this one has only the first tension strap 15, as well as the first and fourth tension straps 14.
[0057] FIG. 4 shows a view on the lateral side of a running shoe according to a further embodiment of the invention. In contrast to the embodiment shown in FIG. 3, both the first and the second pulling strap 15 and 16 extend from the medial side over the lateral side and describe a V-shape. The second pulling strap 16 extends in the direction of the first pulling strap 15, but only comes into contact with the latter in the region of the shoe sole 3 on the lateral side.
[0058] FIG. 5 shows a two-dimensional top view on an upper for an upper 2 of a fastener-free running shoe according to the invention with a group of tension straps comprising tension straps 11, 12, 13, as well as 14a and 14b and a group of pulling straps comprising pulling straps 15 and 16. The first pulling strap 15 runs from the front part of the hallux region on the medial side obliquely in the direction of the heel edge, i.e. in the negative y direction, the first pulling strap being angled at the connection position with the second pulling strap 16. The second pulling strap 16 extends from the rear of the hallux region on the medial side obliquely toward the shoe tip toward the first pulling strap 15 and merges with it at the connection position. The first pulling strap 15 divides the upper 2 in the forefoot area into a first functional zone 21 and a second functional zone 22, which is generally also delimited by the first tension strap 13. As indicated by the arrows, the first functional zone is longitudinally pre-tensioned and is force-neutral in the latitudinal direction. The second functional zone is pre-stretched in the longitudinal direction and pre-tensioned in the latitudinal direction. A third functional zone 23 is delimited by the first pulling strap 15 and the second pulling strap 16. This covers the hallux of the wearer when worn. The third functional zone is elastic and preferably force-neutral. The first compressive tension strap 11 extends in the midfoot area of the upper part 2 from the medial to the lateral side and, viewed in y direction, runs in front of the entry opening. When worn, the first tension strap 11 extends on a LONE of the wearer's foot. The second tension strap 12 and the third tension strap 13 run curved from the medial, respectively lateral side towards the first tension strap 11 and each merge into it at a connecting position. Thus, when worn, the tension straps 12 and 13 surround at least the ankles of the wearer's ankle. A fourth tension strap is formed by the tension straps 14a and 14b. These run from the heel edge towards the medial, or lateral side of the upper 2 and therefore surround the wearer's foot at least in the region of the Achilles tendon when worn. Thus, the wearer's foot is substantially completely surrounded on all sides by the tension straps 11, 12, 13, 14a and 14b. A fourth functional zone 24 is formed by the subzones 24a-d and is delimited by the first tension strap 11.
[0059] FIG. 6 shows a pair of feet of a wearer with the corresponding LONES. Comparison with FIG. 4 shows that the fourth tension strap runs over the LONES in the heel area and the first tension strap 11 runs over the LONES in the midfoot area over the foot. The group of LONES in the heel area, over which the fourth tension strap in FIG. 4 runs, run in the same direction over the foot of the wearer, as shown in FIG. 6, or are arranged at least in sections partially parallel to each other. This group of LONES thereby defines a range of LONES. The fourth tension strap is arranged exclusively above this area, or runs exclusively over this area.
