Abstract
A sole assembly for an article of footwear has a curved spring plate that stores and releases spring energy to aid in forward propulsion. The curved spring plate has a center portion and opposite end portions extending from the center portion. A retaining member is secured to the end portions such that the retaining member spans across and bows the center portion. Flexing of the spring plate stores spring energy in the spring plate that urges the center portion to unflex and release the spring energy.
