an anterior-most point configured to be disposed in a forefoot region of the sole structure;
a posterior-most point configured to be disposed within a heel region of the sole structure;
an aft point located sixty percent (60%) of a total length of the plate rearward from the anterior-most point and co-planar with the anterior-most point and the posterior-most point in a relaxed configuration;
a metatarsophalangeal (MTP) point located thirty percent (30%) of the total length of the plate rearward from the anterior-most point and configured to oppose an MTP joint of a foot during use;
