Abstract

The present invention generally relates to soles in particular midsoles for sports shoes. According to an aspect, an additively manufactured sole is provided. The sole comprises a lattice structure, the lattice structure comprising a plurality of cell elements. The sole further comprises a heel element, three-dimensionally encompassing the heel. Moreover, the sole comprises a base portion interconnecting the heel element and the lattice structure, wherein the base portion has an extension arranged to connect to a plurality of adjacent cell elements, wherein the plurality of adjacent cell elements is not positioned along an edge of the lattice structure.

First claim

What is claimed is:

1 . An additively manufactured sole, in particular a midsole, for a sports shoe, comprising:
a lattice structure, the lattice structure includes a plurality of cell elements; a heel element that three-dimensionally encompasses the heel; a base portion interconnecting the heel element and the lattice structure, wherein the base portion has an extension that connects to a plurality of adjacent cell elements, and wherein the plurality of adjacent cell elements are not positioned along an edge of the lattice structure.

2 . The sole according to claim 1 , wherein a physical property decreases from a rim of the sole towards a center of the sole, the physical property selected from the group consisting of density, stiffness, and air permeability.

3 . The sole according to claim 1 , wherein a geometry of the plurality of cell elements is approximately constant along a thickness of the sole.

4 . The sole according to claim 1 , wherein at least two of the lattice structure, the heel element and the base portion are manufactured from the same class of material, in particular from at least one of polyether block amide and thermoplastic polyurethane.

5 . An additively manufactured sole, in particular a midsole, for a sports shoe, comprising:
a lattice structure, the lattice structure includes a plurality of cell sites, wherein a majority of the cell sites include interconnected cell elements, and wherein a subset of the cell sites include cell elements with fewer connections to at least one adjacent cell site than the majority of the cell sites or with a cell vacancy.

6 . The sole according to claim 5 , wherein at least one of the cell sites of the subset is arranged at a surface of the lattice structure, in particular at an edge of the lattice structure.

7 . The sole according to claim 5 , wherein at least one of the cell sites of the subset is arranged in a heel region of the sole.

8 . The sole according to claim 5 , wherein at least one but not more than 30 cell sites that are not part of the subset are arranged in between two closest cell sites of the subset.

9 . The sole according to claim 1 , wherein the sole further comprises an additively manufactured side or torsional stability elements.

10 . The sole according to claim 1 , wherein the sole is at least partly fabricated by means of laser sintering.

11 . The sole according to claim 1 , wherein the sole comprises a polymer material, in particular a polymer material reclaimed from an ocean.

12 . A sole, in particular a midsole, for a sports shoe, comprising:
an additively manufactured lattice structure; a functional element that is manufactured separately from the lattice structure, wherein the lattice structure and the functional element include at least one receptacle, and wherein the functional element and the lattice structure are mechanically attached to each other via the at least one receptacle.

13 . The sole according to claim 12 , wherein the receptacle comprises a snap-fit or a snap-fasten element.

14 . The sole according to claim 12 , wherein the lattice structure comprises a polymer material, in particular a polymer material reclaimed from an ocean.

15 . The sole according to claim 1 , wherein the lattice structure comprises a plurality of lattice layers.

16 . The sole according to claim 1 , wherein the lattice structure comprises at least two regions that have different physical properties, in particular different densities, different stiffness, or different air permeability.

17 . The sole according to claim 1 , wherein the lattice structure is adapted to extend essentially across the entire foot.

18 . The sole according to claim 1 , wherein the lattice structure comprises at least one cell element shaped as a dodecahedron, in particular a rhombic dodecahedron.

19 . The sole according to claim 1 , wherein the lattice structure comprises at least one fluid channel extending from a top surface of the lattice structure to a bottom or side surface of the lattice structure.

20 . The sole according to claim 1 , wherein the lattice structure comprises at least two cell elements with different geometry.

21 . The sole according to claim 1 , wherein the sole further comprises a solid rim element additively manufactured with the lattice structure, the solid rim element circulating along a rim of the lattice structure.

22 . The sole according claim 1 , wherein the lattice structure comprises a first region with a first plurality of cell elements having a first geometry and a second region with a second plurality of cells having a second geometry.

23 . The sole according claim 1 , wherein the lattice structure comprises at least one moveable element.

24 . A shoe with an upper and a sole according to claim 1 .

25 . The shoe according to claim 24 , wherein the sole and the upper are directly connected to each other without an intermediate Strobel last.

26 . The shoe according to claim 24 , wherein the upper is connected to a solid rim element.

27 . The shoe according to claim 24 , wherein the upper comprises a yarn that includes a polymer material, in particular a polymer material reclaimed from an ocean.

28 . The shoe according to claim 24 , wherein the upper and the sole comprise the same class of material, in particular thermoplastic polyurethane or polyether block amide.
