Abstract
An article of footwear is disclosed that includes an upper and a midsole. A first midsole impact force attenuation structure or system is arranged at least within the toe region of the midsole. A second midsole impact force attenuation structure or system is arranged at least within the heel region of the midsole, such that the second midsole impact force attenuation structure or system includes a molded heel region member extending from a lateral side of the article of footwear to a medial side; the heel region member having a hollow central region defined by a first radius of curvature in a direction toward the toe region and a second radius of curvature in a direction toward the heel region. The first radius of curvature is different from the second radius of curvature. The heel region member may be in an asymmetrical stiffness construction.
