1. An article of footwear, comprising:
- a sole structure having a longitudinal direction extending along a length of the article of footwear and a lateral direction extending along a width of the article of footwear;
the sole structure including a midsole component and at least one outer sole member;
the midsole component including a first outer surface with a recessed portion;
the outer sole member having a second outer surface;
wherein the recessed portion is configured to receive the outer sole member;
a region of the sole structure including a first portion in the first outer surface of the midsole component and a second portion in the second outer surface of the outer sole member;
the region including a set of holes arranged in an auxetic configuration;
wherein the auxetic configuration is configured such that when the region of the sole structure is under longitudinal tension it expands in both the longitudinal direction and the lateral direction and when the region of the sole structure is under lateral tension it expands in both the lateral direction and the longitudinal direction; and
wherein the auxetic configuration extends without interruption from the first portion into the second portion.

Abstract
An article with a sole structure including a midsole component and an outer sole member are described. The sole structure includes a set of holes arranged in an auxetic configuration that permit the sole to expand in an auxetic manner. The set of holes extends through the midsole component and the outer sole member and both the midsole component and the outer sole member are exposed on an outer surface of the sole structure.
