A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of sole elements with apertures. The sole elements have may rotate with respect to each other when the sole is under lateral or longitudinal tension, thus increasing the lateral and longitudinal dimensions of the sole. One or more auxetic or flat liners may be used to prevent entry of debris into the apertures.

1. An article of footwear comprising: a sole structure comprising an auxetic layer and a first liner,wherein the auxetic layer includes a pattern of apertures formed by sole elements surrounding the apertures;wherein each of the sole elements has a plurality of vertices;wherein the sole elements are joined at their vertices, and wherein the sole elements can rotate with respect to one another about their vertices;wherein the auxetic layer is characterized by having a lateral direction, a longitudinal direction and a vertical direction;wherein the auxetic layer is configured to expand in the lateral direction and the longitudinal direction when tension is applied to the auxetic layer in the lateral direction;wherein the auxetic layer is configured to expand in the lateral direction and the longitudinal direction when tension is applied to the auxetic layer in the longitudinal direction;wherein the apertures comprise openings on opposite sides of the auxetic layer that extend through the auxetic layer in the vertical direction;wherein the first liner comprises a continuous sheet of material that is disposed adjacent to the auxetic layer, wherein the first liner is approximately parallel to the auxetic layer and wherein the first liner inhibits the introduction of debris into the openings of the apertures in the auxetic layer;wherein the first liner is an auxetic liner that comprises an auxetic structure with projections that mate with and fit into the apertures in the auxetic layer; andwherein the projections extend through the openings of the apertures through the vertical direction of the auxetic layer. 2. The article of footwear according to claim 1, wherein the sole elements have a polygonal geometry. 3. The article of footwear according to claim 1, wherein the apertures are polygonal apertures that have reentrant sides. 4. The article of footwear according to claim 1, wherein each of the apertures has a center, and wherein when a portion of the auxetic layer is under vertical compression, the sole elements in the portion of the auxetic layer are forced towards the center of the apertures. 5. The article of footwear according to claim 1, wherein a shape of the projections matches the shape of the openings of the apertures. 6. The article of footwear according to claim 1, wherein the first liner is disposed on a first side of the auxetic layer, wherein the sole structure further comprises a second liner disposed on a second side of the auxetic layer that is opposite to the first side of the auxetic layer. 7. The article of footwear according to claim 1, wherein the auxetic layer is an auxetic outsole. 8. The article of footwear according to claim 1, wherein the auxetic layer is an auxetic midsole. 9. The article of footwear according to claim 1, wherein the first liner is disposed inwardly of the outsole, further comprising a second liner disposed outwardly of the outsole. 10. An article of footwear comprising: an auxetic layer and an auxetic liner,wherein the auxetic layer includes a pattern of apertures formed by geometric features surrounding the apertures;wherein each of the geometric features has a plurality of vertices;wherein the geometric features are joined at their vertices such that the vertices function as hinges that allow the geometric features to rotate with respect to each other;wherein the auxetic layer and the auxetic liner are characterized by having a lateral direction, a longitudinal direction and a vertical direction;wherein when a portion of the auxetic layer is under lateral tension, it expands in both the lateral direction and the longitudinal direction, and when a portion of the auxetic layer is under longitudinal tension it expands in both the longitudinal direction and the lateral direction, andwherein when a portion of the auxetic liner is under lateral tension, it expands in both the lateral direction and the longitudinal direction, and when a portion of the auxetic liner is under longitudinal tension it expands in both the longitudinal direction and the lateral direction;wherein the apertures comprise openings on opposite sides of the auxetic layer that extend through the auxetic layer in the vertical direction;wherein the auxetic liner comprises a continuous sheet of material that includes projections;wherein the auxetic liner is disposed on a first surface of the auxetic layer and mates with the auxetic layer; andwherein the projections are shaped to fit into the openings of the apertures and extend through the apertures in the vertical direction to mate the auxetic liner with the auxetic layer. 11. The article of footwear according to claim 10, further comprising a flat outsole liner disposed on a second surface of the auxetic layer that is opposite to the first surface of the auxetic layer. 12. The article of footwear according to claim 11, wherein the flat outsole liner is disposed outwardly of the auxetic layer. 13. The article of footwear according to claim 10, wherein the auxetic liner is disposed outwardly of the auxetic layer. 14. The article of footwear according to claim 10, wherein the geometric features are polygonal features. 15. The article of footwear according to claim 10, wherein the geometric features are triangular features. 16. An article of footwear comprising: an upper and a sole structure attached to the upper, wherein the sole structure comprises an auxetic layer and a first liner,wherein the auxetic layer comprises a pattern of apertures formed by geometric features surrounding the apertures;wherein the geometric features are joined at their vertices such that they function as hinges thereby allowing the geometric features to rotate with respect to each other;wherein the auxetic layer is characterized by having a lateral dimension and a longitudinal dimension;wherein when the auxetic layer is in an unstressed state, the auxetic layer is characterized by having an unstressed configuration with an unstressed longitudinal dimension and an unstressed lateral dimension, and when the auxetic layer is under tension the auxetic layer has an expanded configuration with an expanded longitudinal dimension and an expanded lateral dimension, wherein the expanded longitudinal dimension is greater than the unstressed longitudinal dimension and wherein the expanded lateral dimension is greater than the unstressed lateral dimension;wherein when the auxetic layer is under tension, the first liner expands simultaneously with the auxetic layer such that the expansion of the first liner is compatible with the expansion of the auxetic layer;wherein the apertures in the auxetic layer comprise openings on opposite sides of the auxetic layer that extend through the auxetic layer in a vertical direction; andwherein the first liner comprises a continuous sheet of material that includes projections that extend through the openings of the apertures in the vertical direction of the auxetic layer. 17. The article of footwear according to claim 16, wherein the first liner is an auxetic liner that mates with the auxetic layer and conforms to the auxetic layer. 18. The article of footwear according to claim 17, wherein the first liner is made of a resilient and elastic material. 19. The article of footwear according to claim 16, wherein the first liner is a flat, elastic and resilient liner. 20. The article of footwear according to claim 16, further comprising a second liner disposed adjacent to and parallel to a second surface of the auxetic layer.
