Abstract
A plate for an article of footwear having a sole structure includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use.
