Abstract
An outsole for an article of footwear including a base and a plurality of lugs extending from the base in the forefoot and in the heel portions of the outsole. The lugs each include a leading edge and a trailing edge, and are individually contoured to include a profile increasing in height relative to the base from the leading edge to the trailing edge. The plurality of lugs can also collectively form a contour having an increasing height profile from toe to heel in both the forefoot portion and the heel portion of the outsole. The shape of the lugs, both individually and collectively, permits efficient energy return when walking and simultaneously provides localized, independent reactivity to accommodate a wearer's pressure profile and gait.
