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.
