Abstract

The shoe includes a shoe upper and a sole connected to the shoe upper. The sole includes an upper sole element, and a lower sole element. The shoe also includes an elongated spring element attached at both ends to the shoe upper, or attached at one to the shoe upper and the other end to the upper side element. The elongated spring element exerts a force on the upper sole element to pull the upper sole element away from the lower sole element. The upper sole element has a surface on which the sole of a foot of a wearer of the shoe rests during use of the shoe. The upper sole element rests on the lower sole element during use of the shoe due to the weight of the wearer of the shoe. The elongated spring element pulls at least a part of the upper sole element away from the lower sole element to separate the part of the upper sole element from the lower sole element, during non-use of the shoe. The elongated spring element can be a rubber band.

First claim

The invention claimed is:

1. A shoe comprising:
a shoe upper; and
a sole connected to the shoe upper,
wherein the sole comprises:
an upper sole element;
a lower sole element; and
a rubber band, the rubber band being adapted to exert on the upper sole element a force that pulls at least a part of the upper sole element away from the lower sole element;
wherein the upper sole element has a surface on which the sole of a foot of a wearer of the shoe rests during use of the shoe,
wherein the upper sole element rests on the lower sole element during use of the shoe due to a weight of the wearer of the shoe, and
wherein the rubber band pulls at least the part of the upper sole element away from the lower sole element, thereby separating at least the part of the upper sole element from the lower sole element, during non-use of the shoe,
wherein the rubber band has a first end and a second end, and the first end and the second end of the rubber band are fixed directly to the shoe upper and a section of the rubber band between the first end and the second end passes under the upper sole element and above the lower sole element.

2. The shoe according to claim 1 , wherein the upper sole element comprises an insole.

3. The shoe according to claim 1 , wherein the lower sole element comprises a midsole, wherein an outer sole is arranged at a bottom side of the midsole.

4. The shoe according to claim 1 , wherein the rubber band is disposed in a heel region of the upper sole element.

5. The shoe according to claim 4 , wherein the upper sole element is adapted to pivot around a horizontal swivel axis located in a toe region of the shoe.

6. The shoe according to claim 1 , wherein contact between the upper sole element and the lower sole element occurs in a contact area during use of the shoe, wherein the upper sole element separates from at least 90% of the contact area during non-use of the shoe.

7. The shoe according to claim 1 , wherein only the part of the upper sole element separates from the lower sole element during non-use of the shoe.

8. The shoe according to claim 7 , wherein the part of the upper sole element that separates from the lower sole element during non-use of the shoe is a lamellar section.

9. The shoe according to claim 8 , wherein the lamellar section has a rectangular shape from a top plan view.

10. The shoe according to claim 9 , wherein the lamellar section has a first width that is between 40% and 80% of a second width of a heel region of the shoe.

11. The shoe according to claim 9 , wherein the lamellar section has a first length that is between 50% and 90% of a second length of the shoe.

12. The shoe according to claim 1 , wherein the shoe is a soccer shoe.
