Abstract

A shoe having a sole connected with a shoe upper part. The sole includes: a first sole part having a ground plate, wherein a plurality of first damping elements which extend in a direction of loading are integrally shaped at the ground plate, a second sole part having a cover plate, wherein a plurality of second damping elements which extend in the direction of loading are integrally shaped at the cover plate, a connection part which includes a plurality of interconnected plugin connections. Each plug-in connection has a first plug connector extending downwards in the direction of loading and a second plug connector extending upwards in the direction of loading. The first plug connection frictionally engages into the hollow-cylindrical section of the first damping element and wherein the second plug connection frictionally engages into the hollow-cylindrical section of the second damping element.

First claim

The invention claimed is:

1. A shoe, which comprises a sole and a shoe upper part, wherein the sole is connected with the shoe upper part, wherein the sole comprises:
a first sole part which comprises a ground plate, wherein a plurality of first damping elements which extend in a direction of loading are integrally shaped at the ground plate, the direction of loading being perpendicular to a ground when the shoe is flat on the ground, wherein the first damping elements are respectively formed as hollow bodies and comprise a hollow-cylindrical section in an upper end region of the respective first damping element;
a second sole part which comprises a cover plate, wherein a plurality of second damping elements which extend in the direction of loading are integrally shaped at the cover plate, wherein the second damping elements are respectively formed as hollow bodies and comprise a hollow-cylindrical section in a lower end region of the respective second damping element;
a connection part which comprises a plurality of plug-in connections which are directly connected with one another such that the connection part including all plug-in connections is a one-piece formed part, wherein each plug-in connection comprises a first plug connector which extends downwards in the direction of loading and a second plug connector which extends upwards in the direction of loading, wherein the first plug connector is designed for frictionally engaging into the hollow-cylindrical section of the first damping element and wherein the second plug connector is designed for frictionally engaging into the hollow-cylindrical section of the second damping element, wherein, in a relaxed state of the shoe, a lowermost extent of each first plug connector is vertically above and spaced away from a lowermost extent of the ground plate.

2. The shoe according to claim 1 , wherein each hollow-cylindrical section of the first damping elements of the plurality of first damping elements has an inner diameter, and each hollow-cylindrical section of the second damping elements of the plurality of second damping elements has an inner diameter, wherein the first plug connector and the second plug connector are each dimensioned so as to fit in each respective inner diameter of each respective hollow-cylindrical section in a press fit manner, wherein the first sole part including all the first damping elements is a one-piece formed part, and wherein the second sole part including all the second damping elements is a one-piece formed part.

3. The shoe according to claim 1 , wherein the first sole part is surrounded by an edge which extends laterally upwards when the shoe is flat on the ground.

4. The shoe according to claim 1 , wherein the second sole part has an extension so that the second sole part covers a rear region of the sole and leaves a front region of the sole uncovered by the second sole part.

5. The shoe according to claim 4 , wherein the connection part comprises the plug-in connections only in the rear region which is covered by the second sole part.

6. The shoe according to claim 5 , wherein the connection part comprises at least one flat footrest in the front region which is not covered by the second sole part.

7. The shoe according to claim 1 , wherein each of the first damping elements consists of two partial hollow bodies, including an upper partial hollow body and a bottom partial hollow body, which are connected together by a connection section which extends laterally to the direction of loading, wherein the upper partial hollow body is formed by the hollow-cylindrical section in the upper region end of the respective first damping element.

8. The shoe according to claim 7 , wherein the outer dimension of the upper partial hollow body is smaller than the outer dimension of the bottom partial hollow body.

9. The shoe according to claim 1 , wherein each of the second damping elements consists of two partial hollow bodies, including an upper partial hollow body and a bottom partial hollow body, which are connected with another by a connection section which extends laterally to the direction of loading, wherein the bottom partial hollow body is formed by the hollow-cylindrical section in the lower end region of the respective second damping element.

10. The shoe according to claim 9 , wherein the outer dimension of the bottom partial hollow body is smaller than the outer dimension of the upper partial hollow body.

11. The shoe according to claim 1 , wherein the plug-in connections of the connection part are connected with another by a plurality of connection rods.

12. The shoe according to claim 11 , wherein two adjacent ones of the plurality of plug-in connections of the connection part are connected to one another with one of the connection rods.

13. The shoe according to claim 1 , wherein the shoe upper part is connected with the first sole part.

14. The shoe according to claim 1 , wherein the shoe upper part is connected with the sole by a form-fit connection.
