The invention relates to a sliding element for a shoe sole. The sliding element includes an upper sliding surface and a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface so as to be slideable in at least two directions. The upper sliding surface can form a lower side of an upper sliding plate and the lower sliding surface can form an upper side of a lower sliding plate. A relative sliding movement between the upper sliding surface and the lower sliding surface distributes the deceleration of the shoe sole over a greater time period and allows the foot to feel as if it is wearing a conventional shoe that contacts a surface with reduced friction, for example, a soft forest ground. As a result, the force acting on the wearer and the momentum transfer on his or her muscles and bones are reduced.

1. A sliding element for a shoe sole, comprising:an upper sliding surface;a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface such as to be slideable in at least two directions;at least one projection arranged on one of the two sliding surfaces for engaging a corresponding recess at least partially defined by the other sliding surface to limit the sliding movement of one sliding surface with respect to the other sliding surface; andat least one cushioning element arranged in the recess to cushion the movement of the upper sliding surface with respect to the lower sliding surface.2. The sliding element of claim 1, wherein the lower sliding surface comprises the projection for engaging the recess of the upper sliding surface.3. The sliding element of claim 2, wherein the projection comprises a pin-like shape and the recess comprises an elliptical shape.4. The sliding element of claim 3, wherein a major axis of the elliptically shaped recess is inclined with respect to a longitudinal axis of the shoe sole.5. The sliding element of claim 4, wherein the projection comprises a starting position arranged at a top end of the elliptically shaped recess.6. The sliding element of claim 1, wherein the upper sliding surface forms a lower side of an upper sliding plate and the lower sliding surface forms an upper side of a lower sliding plate and the upper sliding plate and the lower sliding plate are similarly shaped.7. The sliding element of claim 6, wherein the upper sliding plate and the lower sliding plate comprise corresponding concave and convex shapes.8. The sliding element of claim 7, wherein the lower sliding plate is slideable relative to the upper sliding plate in at least three directions.9. The sliding element of claim 1, further comprising a spring element, wherein the spring element is deflected by a sliding movement of the upper sliding surface relative to the lower sliding surface.10. The sliding element of claim 9, wherein the spring element forms an elastic envelope at least partially encompassing the upper sliding surface and the lower sliding surface.11. The sliding element of claim 10, wherein the elastic envelope seals an intermediate space between the upper sliding surface and the lower sliding surface.12. The sliding element of claim 11, wherein the elastic envelope comprises a lower side including at least one profile element disposed thereon.13. A sole for an article of footwear, the sole comprising:at least one sliding element, comprising:an upper sliding surface;a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface such as to be slideable in at least two directions;at least one projection arranged on one of the two sliding surfaces for engaging a corresponding recess at least partially defined by the other sliding surface to limit the sliding movement of one sliding surface with respect to the other sliding surface; andat least one cushioning element arranged in the recess to cushion the movement of the upper sliding surface with respect to the lower sliding surface.14. The sole of claim 13, wherein the upper sliding surface is attached to a midsole of the sole.15. The sole of claim 13, wherein the at least one sliding element is arranged in a heel area of the sole.16. The sole of claim 15, wherein the at least one sliding element is arranged on a lateral side of the heel area.17. The sole of claim 13, wherein the at least one sliding element is arranged in a forefoot area of the sole.18. The sole of claim 17, wherein the at least one sliding element is arranged on a rear section of the forefoot area.19. The sole of claim 13, wherein the upper sliding surface forms a lower side of an upper sliding plate and the lower sliding surface forms an upper side of a lower sliding plate and the upper sliding plate and the lower sliding plate are similarly shaped.20. The sole of claim 19, wherein the upper sliding plate and the lower sliding plate comprise corresponding concave and convex shapes.21. The sole of claim 20, wherein the lower sliding plate is slideable relative to the upper sliding plate in at least three directions.22. An article of footwear including an upper and a sole, the sole comprising:at least one sliding element, comprising:an upper sliding surface;a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface such as to be slideable in at least two directions;at least one projection arranged on one of the two sliding surfaces for engaging a corresponding recess at least partially defined by the other sliding surface to limit the sliding movement of one sliding surface with respect to the other sliding surface; andat least one cushioning element arranged in the recess to cushion the movement of the upper sliding surface with respect to the lower sliding surface.23. The article of footwear of claim 22, wherein the upper sliding surface forms a lower side of an upper sliding plate and the lower sliding surface forms an upper side of a lower sliding plate and the upper sliding plate and the lower sliding plate are similarly shaped.24. The article of footwear of claim 23, wherein the upper sliding plate and the lower sliding plate comprise corresponding concave and convex shapes.25. The article of footwear of claim 24, wherein the lower sliding plate is slideable relative to the upper sliding plate in at least three directions.
