Abstract
An article of footwear has a sole structure with an extension portion that maintains contact with the ground during a forward stride, extending the time period for deceleration of loads applied to the sole structure. The article of footwear comprises an upper and a sole structure. The upper has a forefoot region with a foremost extent. The sole structure has a forefoot portion underlying the forefoot region, and an extension portion extending forward from the forefoot portion. The extension portion extends forward of the foremost extent of the upper from a forward edge of the forefoot portion to a distal end. A top side of the extension portion is spaced apart from the upper between the forward edge and the distal end. The extension portion establishes a propulsion surface beyond the foremost extent of the upper during a forward stride.
