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.
Claims24
An additively manufactured sole, in particular a midsole, for a sports shoe, comprising:
- a lattice structure extending from a heel region to a toe region of the sole, and further having a top surface and a side surface that meet at an edge, wherein the lattice structure comprises a plurality of struts connected at nuclei defining a plurality of open cell elements including a first plurality of cell elements on the top surface at the edge and a second plurality of cell elements on the top surface inward of the first plurality of cell elements;
- a solid front portion formed continuously with the lattice structure at a front tip of the sole, wherein the solid front portion extends from the top surface to a bottom surface of the sole and comprises no lattice structure;
- a heel element that three-dimensionally encompasses the heel;
- a base portion interconnecting the heel element and the lattice structure,
- wherein the base portion extends inwardly to connect to the first plurality of cell elements and the second plurality of cell elements, and wherein the lattice structure, the heel element, the solid front portion, and the base portion are integrally additively-manufactured.
An additively manufactured sole, in particular a midsole, for a sports shoe, comprising:
- a lattice structure having a top surface and a side surface that meet at an edge, wherein the lattice structure includes a plurality of cell elements including a first plurality of cell elements on the top surface at the edge and a second plurality of cell elements on the top surface inward of the first 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 extends inwardly to connect to the first plurality of cell elements and the second plurality of cell elements, and wherein the lattice structure, the heel element, and the base portion each comprises the same material, and wherein the material comprises at least 50% of a reclaimed polymer.
An additively manufactured sole for a sports shoe, comprising:
- a lattice structure having a top surface and a side surface that meet at an edge, wherein the lattice structure extends from a lateral side to a medial side of the sole and comprises a plurality of struts connected at nuclei defining a plurality of cell elements including a first plurality of cell elements on the top surface at the edge and a second plurality of cell elements on the top surface inward of the first plurality of cell elements, wherein each of the plurality of cell elements has a shape selected from the group consisting of a dodecahedron, a tetrahedron, an icosahedron, a cube, a cuboid, a prism, and a parallelepiped;
- a solid front portion that extends continuously from the lattice structure at a front tip of the sole, wherein the solid front portion extends from the top surface to a bottom surface of the sole and comprises no lattice structure;
- a heel element that three-dimensionally encompasses the heel;
- a base portion interconnecting the heel element and the lattice structure;
- and
- an outsole arranged on a bottom surface of the lattice structure,
- wherein the base portion extends inwardly to connect to the first plurality of cell elements and the second plurality of cell elements, and wherein the lattice structure, the solid front portion, the heel element, the base portion, and the outsole are integrally additively-manufactured.
