Shoe sole
Described are soles for shoes, and shoes with such soles. The sole includes a first partial region and a second partial region, a cushioning element, and a protection element. The cushioning element is arranged within at least a portion of the first partial region and within at least a portion of the second partial region. The protection element is also arranged within at least a portion of the first partial region and within at least a portion of the second partial region. The cushioning element has a greater stiffness in the first partial region than in the second partial region. When a wearer treads down with the sole on a surface, the protection element has a larger contact area with the surface in the first partial region than in the second partial region.
1. A sole for a shoe comprising
a first partial region and a second partial region;
a cushioning element comprising randomly arranged particles of an expanded material, wherein the cushioning element is arranged within at least a portion of the first partial region and within at least a portion of the second partial region; and
a protection element arranged within at least a portion of the first partial region and within at least a portion of the second partial region, wherein the protection element comprises at least one first protrusion having a flattened surface in the first partial region and at least one second protrusion having a cone-shape or pyramid-shape in the second partial region, wherein the at least one first protrusion has a different shape than the at least one second protrusion, wherein the at least one second protrusion at least partially presses into the cushioning element when a wearer treads down on the sole, and wherein the at least one first protrusion has a greater contact area with a surface when treading down than the at least one second protrusion.
2. The sole according to claim 1 , wherein the protection element is arranged beneath the cushioning element and directly at the cushioning element.
3. The sole according to claim 1 , wherein the sole further comprises a midsole, and the cushioning element forms at least a portion of the midsole.
4. The sole according to claim 1 , wherein the sole further comprises an outsole, and the protection element forms at least a portion of the outsole.
5. The sole according to claim 1 , wherein the cushioning element comprises a greater density in the first partial region than in the second partial region.
6. The sole according to claim 1 , wherein the particles of the expanded material are selected from a group consisting of expanded thermoplastic polyurethane particles and expanded polyether-block-amide particles.
7. The sole according to claim 1 , wherein the cushioning element further comprises a reinforcing element.
8. The sole according to claim 7 , wherein the reinforcing element extends into the first partial region and the second partial region.
9. The sole according to claim 1 , wherein the protection element comprises a greater bending stiffness in the first partial region than in the second partial region.
10. The sole according to claim 1 , wherein the first partial region extends on at least a portion of a medial side of the sole.
11. The sole according to claim 1 , wherein the second partial region extends on at least a portion of a lateral side of the sole.
12. A shoe with a sole according to claim 1 .
13. A sole for a shoe comprising
a first partial region and a second partial region;
a cushioning element comprising randomly arranged particles of an expanded material, wherein the cushioning element is arranged within at least a portion of the first partial region and within at least a portion of the second partial region; and
a protection element arranged within at least a portion of the first partial region and within at least a portion of the second partial region;
wherein the protection element comprises a plurality of openings in the first partial region and in the second partial region, at least one first protrusion in the first partial region and at least one second protrusion in the second partial region,
wherein on average, the plurality of openings in the second partial region occupy a larger area than the plurality of openings in the first partial region,
wherein the at least one second protrusion at least partially presses into the cushioning element when a wearer treads down on the sole,
wherein the at least one first protrusion has a flattened surface and the at least one second protrusion has a cone-shape or pyramid-shape,
wherein the at least one first protrusion has a different shape than the at least one second protrusion, and
wherein the at least one first protrusion has a greater contact area with a surface when treading down than the at least one second protrusion.
14. The sole according to claim 13 , wherein the particles of the expanded material are selected from a group consisting of expanded thermoplastic polyurethane particles and expanded polyether-block-amide particles.
15. The sole according to claim 13 , wherein the protection element comprises a greater bending stiffness in the first partial region than in the second partial region.
16. The sole according to claim 13 , wherein the cushioning element comprises a greater density in the first partial region than in the second partial region.
17. A sole for a shoe comprising
a first partial region which extends on at least a portion of a medial side of the sole and a second partial region which extends on at least a portion of a lateral side of the sole;
a cushioning element comprising randomly arranged particles of an expanded material, wherein the cushioning element is arranged within at least a portion of the first partial region and within at least a portion of the second partial region; and
a protection element arranged within at least a portion of the first partial region and within at least a portion of the second partial region, wherein the protection element comprises at least one first protrusion having a flattened surface in the first partial region and at least one second protrusion having a cone-shape or pyramid-shape in the second partial region, wherein the at least one first protrusion has a different shape than the at least one second protrusion; wherein the at least one second protrusion at least partially presses into the cushioning element when a wearer treads down on the sole, and wherein the at least one first protrusion has a greater contact area with a surface when treading down than the at least one second protrusion.
18. The sole according to claim 17 , wherein the protection element comprises a greater bending stiffness in the first partial region than in the second partial region.
19. The sole according to claim 17 , wherein the cushioning element comprises a greater density in the first partial region than in the second partial region.
20. The sole according to claim 17 , wherein the cushioning element further comprises a reinforcing element which extends into the first partial region and the second partial region.
21. The sole according to claim 17 , wherein the particles of the expanded material are selected from a group consisting of expanded thermoplastic polyurethane particles and expanded polyether-block-amide particles.
