Description

[0028] The invention will also be described hereafter with respect to further features and advantages on the basis of exemplary embodiments, which are explained in greater detail on the basis of the figures.

[0029] In the figures:

[0030] FIG. 1 shows a schematic illustration of a sole for a running shoe according to the invention in an exploded view, including a last for the production of the sole; and

[0031] FIG. 2 shows a sole for a running shoe according to the invention in a view from below (partially in an exploded illustration).

[0032] The same reference signs are used in the following description for identical and identically acting parts.

[0033] FIG. 1 shows a schematic illustration of a sole 10 for a running shoe according to the invention in an exploded view and a last 11 for the production thereof. The last 11 comprises a recessed last ball roll 12 and is distinguished by an upward bend 13 and a comparatively tall toe vault 14, for example, of at least 10 mm. The last ball roll 12 at least partially defines the ball roll 38 of the sole 10 during production, as can also be seen in FIG. 2. The ball roll of the sole 10 is approximately 5 mm behind the natural ball position after production.

[0034] The sole 10 comprises an insole 15, a midsole 16, a torsion stabilizer 17, a heel wedge 18 as a heel damping element, and an outsole 19 having a profile. The hardness and flexibility of the shoe can be at least partially set via the insole 15 and therefore the field of use of the shoe can be defined. In this case, a Strobel-stitched embodiment having a comparatively soft textile insole can ensure a high level of flexibility. According to a preferred alternative according to the invention, however, the insole is glued on, specifically in particular with a shoe upper edge on the top side of the outsole. A hard insole promotes stability during running and furthermore enables a precisely defined, in particular uniform force distribution and surface load.

[0035] A forefoot damping element 20 and a pronation support 21 are integrated in the midsole 16. Both the forefoot damping element 20 and also the pronation support 21 are made of a material which is harder than the remaining components of the midsole 16. A midsole ball roll 22 is also recessed to facilitate the rolling off of the foot. The midsole ball roll is defined by a lower vertex line of the midsole.

[0036] The pronation support 21 is arranged in an arch region 23 at an inner edge 24 of the midsole 16 and promotes a pleasant pronation control or stabilization of the arch. In the present exemplary embodiment, the pronation support 22 is arranged within a longitudinal center axis 40 and the inner edge 24 of the midsole 16. The forefoot damping element 20 is arranged in a forefoot region 25 of the midsole 16 and is formed approximately kidney-shaped to relieve the pressure points.

[0037] The sole 10 is divided in two different ways hereafter: on the one hand, into the forefoot region 25 and into a rear foot region 42. These two regions are separated by the ball line. On the other hand, following the anatomy, a division into tarsal region 28, metatarsal region 29, and toe region 30 is performed. The ball line 37 is located inside the metatarsal region 29.

[0038] The midsole 16, if it is desired, is arranged in the shoe below the insole 15. The plate-shaped torsion stabilizer 17 and the heel wedge 18, or the heel damping element, are arranged below the midsole 16. The heel wedge can absorb the initial strike and initiate the rolling off movement, so that the joints are better protected and the rolling off movement is improved. The heel wedge 18 is formed as wedge-shaped and widens in the direction of a heel end 26 of the sole 10. The torsion stabilizer 17 is provided in the arch region 23 and can reduce or prevent the twisting of the forefoot in relation to the heel during a rolling off movement. The outsole 19 is arranged below torsion stabilizer 17 and heel wedge 18. A profile 27 (see also FIG. 2) is adapted to the natural walking picture of humans and follows the S-shaped rolling off line. In this case, the first ground contact can take place on slightly supinated heel. Furthermore, the profile hardness and profile depth of the sole of the shoe according to the invention can be adapted to the different requirements.

[0039] FIG. 2 shows a view of the sole 10 from below. The outsole 19 is divided in this case into a tarsal region 28, a metatarsal region 29, and a toe region 30. An inner tarsal region edge section 31 is formed softer in this case than an outer tarsal region edge section 32. Furthermore, an inner metatarsal region edge section 33 is formed harder than an outer metatarsal region edge section 34. An inner toe region edge section 35 is also harder than an outer toe region edge section 36.

[0040] Furthermore, a ball line 37 is shown in FIG. 2, in relation to which a ball roll 38 is offset to the rear by a ball roll distance 41, as predefined by the last ball roll 12 and the midsole ball roll 22. The ball roll 38 thus defined is offset in the present example by 5 mm to the rear in relation to the ball line 37 in the direction of the heel end 26.

[0041] The sole comprises a heel chamfer 44, wherein a boundary line 43 located closer to the forefoot region is offset to the rear at its inner end.

[0042] The sole 10 can be constructed in a building block fashion. In particular, a set of multiple lasts and/or insoles and/or midsoles and/or torsion stabilizers and/or heel wedges and/or outsoles can be provided. In this case, all elements can be individually adapted in hardness, material embodiment, and shape and therefore the sole can be adapted to different demands and functions, in particular to the requirements of persons having skin and/or circulation problems, in particular feet, for example, for diabetics. The field of use of the sole is thus decisively expanded in an advantageous manner.

[0043] FIG. 2 shows the course of the first envelope line 45 around the circumferential edge of the outsole enveloping the forefoot. The second envelope line 46, which is also schematically shown, is formed longer than the first envelope line 45. The first envelope line 45 extends from the respective opposing ends of the ball line 37 around the circumferential edge of the outsole, which is associated with the forefoot, while the second envelope line 46 extends from the respective opposing ends of the ball roll 38 around the circumferential edge of the outsole enveloping the forefoot. In the following table, the last volume, the length, and the width as well as the position of the ball roll of the shoe according to the invention are compared to the corresponding dimensions and the ball line of a conventional shoe, wherein it is clearly recognizable that the second envelope line 46, which is associated with the recessed ball roll 38 of a shoe according to the invention, is longer than the first envelope line 45, which is associated with a conventional shoe.
