Abstract

The invention relates to a shoe ( 1 ), especially a sports shoe, comprising a sole ( 2 ) and a shoe upper part ( 3 ) linked therewith, the sole ( 2 ) having a receptacle ( 4 ) in which a damping element ( 5 ) is detachably arranged. The aim of the invention is to improve the cushioning and damping behavior of the shoe. According to the Invention, the receptacle ( 4 ) substantially or completely extends through the sole ( 2 ) at an angle to the longitudinal axis (L) of the shoe ( 1 ) and the detachably mounted damping element ( 5 ) is constituted of a plate-type base ( 6 ) that comprises a plurality of recesses ( 7 ) in which damping parts ( 8 ) can be disposed. The recesses ( 7 ) in the damping element ( 5 ) extend across the entire height (H) of the damping element ( 5 ) in the vertical direction (V).

Claims (22)

1. A shoe ( 1 ) with a sole ( 2 ) and a shoe upper part ( 3 ) connected thereto, the sole ( 2 ) having a receiving space ( 4 ), in which a damping element ( 5 ) is detachably arranged, characterized in that the receiving space ( 4 ) extends substantially or completely through the sole ( 2 ) transversely to the longitudinal axis (L) of the shoe ( 1 );

the detachably arranged damping element ( 5 ) comprises a basic body ( 6 ) of plate-like design, which has a number of recesses ( 7 ) in which damping parts ( 8 ) are arranged, the recesses ( 7 ) in the damping element ( 5 ) extending over the entire height (H) of the damping element ( 5 ) in the vertical direction (V); and

a retaining element ( 9 ), which fixes the basic body ( 6 ) in the receiving space ( 4 ), the retaining element ( 9 ) being of stirrup-shaped design and gripping around the sole ( 2 ) from below.

2. The shoe of claim 1 , characterized in that the individual damping parts ( 8 ) for arrangement in the recesses ( 7 ) are selected in such a way that the shoe ( 1 ) or its sole ( 2 ) has a desired spring and damping action and/or a desired pronation or supination action.

3. The shoe of claim 1 , characterized in that the receiving space ( 4 ) in the sole ( 2 ) is arranged in the heel region.

4. The shoe of claim 1 , characterized in that the recesses ( 7 ) have a hexagonal shape seen in the vertical direction (V).

5. The shoe of claim 1 , characterized in that the recesses ( 7 ) and accordingly the damping parts ( 8 ) have a conical shape seen at right angles to the vertical direction (V).

6. The shoe of claim 1 , characterized in that the central recess ( 7 ′) for receiving a central damping part ( 8 ′) is arranged in the damping element ( 5 ) and a number of further recesses ( 7 ″), for receiving further damping parts ( 8 ″) are arranged around the central recess ( 7 ′), the further recesses ( 7 ″) being arranged on a circular path around the center of the central recess ( 7 ′).

7. The shoe of claim 6 , characterized in that there are six further recesses ( 7 ″).

8. The shoe of claim 6 , characterized in that the further recess ( 7 ″) are arranged equidistantly over the circumference of the circular path.

9. The shoe of claim 1 , characterized in that the height (H) of the basic body ( 6 ) in the vertical direction (V) is between 0.3 and 2.0 cm.

10. The shoe of claim 1 , characterized in that the basic body ( 6 ) and/or the damping parts ( 8 ) are made of plastic.

11. The shoe of claim 10 , characterized in that the basic body ( 6 ) and/or of the damping parts ( 8 ) is made of foamed plastic.

12. The shoe of claim 10 , characterized in that the material of the basic body ( 6 ) and/or of the damping parts ( 8 ) has a greater hardness than the material of the sole ( 2 ).

13. The shoe of claim 12 , characterized in that the plastic of the basic body ( 6 ) and/or of the damping parts ( 8 ) has a Shore hardness of between 25A and 45A.

14. The shoe of claim 13 , characterized in that the plastic of the basic body ( 6 ) has a lower hardness than the plastic of the damping parts ( 8 ).

15. The shoe of claim 10 , characterized in that the material of the sole ( 2 ) is translucent or transparent in the region of the basic body ( 6 ) and/or of the damping parts ( 8 ).

16. The shoe of claim 10 , characterized in that the plastic is a polyamide, a polyurethane, a polyethylene, a polypropylene, a polybutane, a polyolefin, a ethylene-vinylacetate polymer, a polyvinyl chloride or a mixture of two or more plastics.

17. The shoe of claim 1 , characterized in that both the sole ( 2 ) and the basic body ( 6 ) have recesses ( 10 , 11 ) for positive interaction with the retaining element ( 9 ).

18. The shoe of claim 1 , characterized in that the sole ( 2 ) comprises an intermediate sole and an outsole connected thereto, and the damping element ( 5 ) is arranged in the intermediate sole.

19. The sole of claim 1 , characterized by a system comprising a number of damping parts ( 8 ) of different hardness provided for optional interchange, which can be arranged in the recesses ( 7 ) of the basic body ( 6 ).

20. The shoe of claim 19 , characterized in that each degree of hardness of the damping part ( 8 ) is assigned a defined color, with which the damping parts ( 8 ) are dyed at least on their outer surface.
