1. A sole structure, comprising:
- a midsole component and an inner sole component;
the midsole component having a longitudinal direction extending along a length of the sole structure, a lateral direction extending along a width of the sole structure, and a vertical direction that is perpendicular to the longitudinal direction and the lateral direction;
the midsole component including a plurality of holes arranged in an auxetic configuration;
wherein the auxetic configuration is configured such that when the midsole component is under longitudinal tension it expands in both the longitudinal direction and the lateral direction and when the midsole component is under lateral tension it expands in both the lateral direction and the longitudinal direction;
wherein the plurality of holes includes at least one through hole that extends through a thickness of the midsole component in the vertical direction between an inner surface and an outer surface of the midsole component;
the midsole component being shaped to receive the inner sole component, wherein the inner sole component is disposed against the inner surface of the midsole component; and
wherein a first density of the midsole component is different than a second density of the inner sole component.

11. An article of footwear, comprising:
-
an upper; a sole structure including a midsole component and an inner sole component; the midsole component having a longitudinal direction extending along a length of the article of footwear, a lateral direction extending along a width of the article of footwear, and a vertical direction that is perpendicular to the longitudinal direction and the lateral direction; the midsole component including an outer surface and an inner surface; the outer surface including a plurality of holes arranged in an auxetic configuration; wherein the auxetic configuration is configured such that when the midsole component is under longitudinal tension it expands in both the longitudinal direction and the lateral direction and when the midsole component is under lateral tension it expands in both the lateral direction and the longitudinal direction; wherein the plurality of holes includes at least one through hole that extends through a thickness of the midsole component in the vertical direction between the inner surface and the outer surface of the midsole component; the inner surface of the midsole component including a central recess that receives the inner sole component; and at least one outer sole member attached to the outer surface of the midsole component. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
