Sole structure for article of footwear

Abstract:

A sole structure for an article of footwear is provided and includes a plate having a concave ground-engaging surface extending between a medial side of the plate and a lateral side of the plate and movable between a relaxed state and a flexed state. The concave surface has an increased radius when moved from the relaxed state to the flexed state. A first ground-engaging member extends from the plate proximate to the medial side of the plate and a second ground-engaging member extends from the plate proximate to the lateral side of the plate. The second ground-engaging member is spaced apart from the first ground-engaging member by a first distance when the plate is in the relaxed state and is spaced apart from the first ground engaging member by a second distance greater than the first distance when the plate is in the flexed state.
