Footwear outsole
First Claim
1. An outsole for an article of footwear comprising:
- a forefoot base defining a plurality of forefoot lug channels;
a plurality of forefoot lugs joined with the forefoot base, each forefoot lug including a forefoot lug leading portion, a forefoot lug trailing portion, and a forefoot lug ground contacting bottom surface, the forefoot lug ground contacting bottom surface disposed a first distance from the forefoot base, the first distance increasing from the forefoot lug leading portion to the forefoot lug trailing portion on each forefoot lug so that each forefoot lug has a rearwardly increasing profile, each of said forefoot lugs surrounded by at least one of the forefoot lug channels;
a heel base defining a plurality of heel lug channels; and
a plurality of heel lugs joined with the heel base, each heel lug including a heel lug leading portion, a heel lug trailing portion, and a heel lug ground contacting bottom surface, the heel lug ground contacting bottom surface disposed a second distance from the heel base, the second distance increasing from the heel lug leading portion to the heel lug trailing portion on each heel lug so that each heel lug has a rearwardly increasing profile, each of said heel lugs surrounded by at least one of the heel lug channels.

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.

12. An outsole for an article of footwear comprising:
-
a base; and a plurality of lugs joined with the base, each lug including a leading edge and a trailing edge, the leading edge aligned with a first point that lies on a first arc, the trailing edge aligned with a second point that lies on a second arc, the first arc and second arc being congruent, the first arc offset from the second arc a pre-selected amount so that the leading edge is closer to the base than the trailing edge on each of the plurality of lugs, the plurality of lugs collectively forming a common rearwardly increasing profile. - View Dependent Claims (13, 14, 15, 16, 17)

18. An outsole for an article of footwear comprising:
-
a base; a plurality of lugs extending from the base, each lug including a leading edge and a trailing edge, each lug including an independent contour having a rearwardly increasing profile relative to the base as the independent contour transitions from the leading edge to the trailing edge, wherein the plurality of lugs collectively form a collective ground contacting contour having another rearwardly increasing profile relative to the base as the collective contour transitions in a direction of toe toward heel on the outsole. - View Dependent Claims (19, 20)
