SOLE ASSEMBLY FOR ARTICLE OF FOOTWEAR

摘要

A sole assembly generally including a flex plate, a heel spring and a heel cup. The flex plate may extend from the rear of the sole through the arch into the forefoot. The heel spring may be an elliptical spring and may have internal resilient stoppers that prevent the spring from bottoming out. The height of the stoppers may increase toward the rear of the sole. The stoppers may be extensions of the outsole fitted up through apertures in the elliptical spring. The heel spring may be disposed beneath the flex plate in the heel region. The heel cup may be disposed above the flex plate in the heel region. The heel cup may have an extension that extends upwardly a sufficient distance to cradle the wearer's heel to provide an enhanced forefoot lever. The flex plate, heel spring and heel cup may be a single unitary component.
