An article of apparel includes at least one panel including a first edge and an opposing second edge. The at least one panel includes an auxetic structure defining a primary elongation direction and a secondary elongation direction. A plurality of lace coupling pairs are positioned along the first edge and the second edge of the at least one panel. Each lace coupling pair defines a lace pull direction that is perpendicular to a line extending through two adjacent lace couplings of the lace coupling pair. Each lace pull direction is defined by the plurality of lace couplings substantially in alignment with either the primary elongation direction or the secondary elongation direction of the auxetic structure between the two adjacent lace couplings of the lace coupling pair.

The footwear article of claim 12, the auxetic structure defining a primary elongation direction and a secondary elongation direction, wherein the primary elongation direction of the auxetic structure is substantially different in the forefoot region than in the heel region. 14. The footwear article of claim 12 wherein the footwear article is a high-top shoe such that the upper includes an ankle region and the integrally formed auxetic structure further extends to the ankle region. 15. The footwear article of claim 12 wherein the void has an hourglass shape. 16. A footwear article comprising: a sole; andan upper connected to the sole, the upper including a forefoot region, a midfoot region, and a heel region, the upper including at least one panel provided in the midfoot region, the at least one panel including a base layer connected to an auxetic layer, the base layer comprising a fabric stretch material and the auxetic layer comprising an auxetic structure defining a repeating pattern of voids. 17. The footwear article of claim 16, wherein the fabric stretch material is a two-way stretch fabric. 18. The footwear article of claim 16, the at least one panel defining a tongue opening between a first edge and an opposing second edge of the at least one panel, the footwear article further including a plurality of couplings positioned along the first edge and the second edge of the at least one panel, and the auxetic structure defining a primary elongation direction and a secondary elongation direction. 19. The footwear article of claim 18, the plurality of couplings including a plurality of lace coupling pairs, each lace coupling pair including two adjacent lace couplings both positioned along either the first edge or the second edge of the at least one panel, each lace coupling pair defining a lace pull direction that is perpendicular to a line extending through the two adjacent lace couplings of the lace coupling pair, each lace pull direction substantially in alignment with either the primary elongation direction or the secondary elongation direction of the auxetic structure. 20. The footwear article of claim 16 wherein the base layer is exposed through a first plurality of the repeating pattern of voids. 21. The footwear article of claim 20 wherein a second plurality of the repeating plurality of voids are filled with material. 22.
