A sole structure for an article of footwear, comprising: a plate member including a first side and a second side;a plurality of segmented portions attached to the second side of the plate member, wherein the plurality of segmented portions are configured to contact a ground surface;the plurality of segmented portions further comprising a first set of segmented portions that are located on a lateral side of the sole structure and a second set of segmented portions that are located on a medial side of the sole structure, wherein the first set of segmented portions comprises a greater number of segmented portions than the second set of segmented portions;wherein the first set of segmented portions are spaced apart in the longitudinal direction and wherein the second set of segmented portions are spaced apart in the longitudinal direction;wherein the first set of segmented portions are separated from the second set of segmented portions in the lateral direction by a central longitudinal portion, wherein the central longitudinal portion extends from a forward edge of the sole structure to a rearward edge of the sole structure, the central longitudinal portion being exposed along the forward edge, the central longitudinal portion also being exposed along the rearward edge;the central longitudinal portion further including a medial arch region, the medial arch region separating a forefoot set of segmented portions from a heel set of segmented portions, the medial arch region extending to a midfoot edge of the sole structure;wherein the plurality of segmented portions comprise a lower layer of the sole structure and wherein the plate member comprises an upper layer of the sole structure; andwherein a maximum cross-sectional thickness of the upper layer is less than a minimum cross-sectional thickness of the lower layer. 8. The sole structure according to claim 7, wherein the minimum cross-sectional thickness of the lower layer is at least two times greater than the maximum cross-sectional thickness of the upper layer. 9. The sole structure according to claim 8, wherein the minimum cross-sectional thickness of the lower layer is at least five times greater than the maximal cross-sectional thickness of the upper layer. 10. The sole structure according to claim 7, wherein the sole structure is configured to enhance vertical bending and torsion about a longitudinal axis. 11. The sole structure according to claim 10, wherein the sole structure is configured to resist lateral bending. 12. The sole structure according to claim 7, wherein the plate member includes a plurality of flex grooves. 13. The sole structure according to claim 12, wherein the width of the plurality of flex grooves is less than the width of the spacing between adjacent segmented portions. 14. The sole structure according to claim 1, wherein the plurality of outwardly extending flexing regions includes a first outwardly extending flexing region secured to a lower surface of the plate member and extending to a ground engaging surface; the plurality of segmented portions including a first segmented portion and a second segmented portion;the first outwardly extending flexing region being disposed between the first segmented portion and the second segmented portion so that the first outwardly extending flexing region divides the first segmented portion from the second segmented portion from the plate surface to the ground engaging surface. 15. The sole structure according to claim 3, wherein a gap between a first side section and a second side section aligns with a first outwardly extending flexing region along a side edge of the sole structure, such that the sole structure accommodates vertical bending along the gap and the first outwardly extending flexing region.
