Abstract
A sole structure for an article of footwear comprises a sole plate that has a forefoot portion with a foot-facing surface. The sole plate has at least one groove extending at least partially transversely in the foot-facing surface. The at least one groove is open when the sole structure is dorsiflexed in a first portion of a flexion range, and closed when the sole structure is dorsiflexed in a second portion of the flexion range that includes flex angles greater than in the first portion of the flexion range.
