Abstract: A track and field shoe can include an upper, a sole structure, and a toe plate. The upper includes a medial side portion, a lateral side portion, and a toe box portion. The sole structure is attached to the upper and includes a spike plate. The spike plate has an anterior portion, a posterior portion, and a plurality of spikes. The spikes are configured for penetrating a track surface. The toe plate is attached to an anterior portion of the toe box portion of the upper. One or more portions of the toe plate are exposed from an exterior surface of the upper. The spikes are spaced apart from the toe plate such that the spikes disengage the track surface when the toe plate contacts the track surface.

Abstract: A sole structure for a footwear article includes a system of support structures. Each support structure includes a tubular body with an inwardly curving wall, which compresses under load to attenuate a force or impact and returns to a resting state when the load is removed.

Abstract: A sole structure for an article of footwear includes an upper cushioning element including a first material having a first durometer, a lower cushioning element including a second material having a second durometer and defining a plurality of first engagement elements, and a plate disposed between the upper cushioning element and the lower cushioning element, the plate including a plurality of second engagement elements cooperating with the first engagement elements to position the plate with respect to the lower cushioning element.

The sole structure is attached to the upper and includes a spike plate. The spike plate has an anterior portion, a posterior portion, a plurality of spikes, and a plurality of rails. The spikes extend in an inferior direction from the anterior portion of the spike plate and are configured for engaging a track surface. The rails extend in a superior direction from the anterior portion of the spike plate and extend over an exterior surface of the toe box portion of the upper, and the rails comprise longitudinal axes that extend in a superior/inferior direction.
