Abstract
An article of footwear has an auxetic sole structure formed from members surrounding apertures. The members may have a trapezoidal geometry. Adjoining members are hingedly connected, so that they can rotate with respect to each other in the plane of the sole structure. The rotation allows the auxetic sole structure to expand when tension is applied.
