Abstract
A sole structure for an article of footwear comprises a sole plate that includes a foot-facing surface with a forefoot portion, and a ground-facing surface opposite from the foot-receiving surface. A tension member is operatively secured to the ground-facing surface and has a portion configured to move relative to the sole plate during dorsiflexion of the sole structure in a first portion of a flexion range, and interfere with the sole plate during dorsiflexion of the sole structure in a second portion of the flexion range greater than the first portion altering the rate of the resultant torque.
