First Claim
Patent Images
1. An article of footwear, comprising:
- a sole including an outer peripheral edge;
a forefoot portion of the outer peripheral edge having a first cross sectional profile shape;
an arch portion of the outer peripheral edge having a second cross sectional profile shape, wherein a lateral side of the second cross sectional profile shape is substantially perpendicular to a ground-contacting surface of the sole substantially throughout the length of the arch portion in a longitudinal direction of the sole; and
a heel portion of the outer peripheral edge having a third cross sectional profile shaped,wherein the first cross sectional profile shape, the second cross sectional profile shape and the third cross sectional profile shape are different from one another,wherein the heel portion includes a lower portion and an upper portion,wherein the lower portion has a substantially convex cross sectional profile shape, andwherein the upper portion has a substantially concave cross sectional profile shape.

7. An article of footwear, comprising:
-
a sole including an outer peripheral edge; and a lower surface of the sole configured to contact a ground surface; the outer peripheral edge comprising a first portion that is substantially curved and is a heel portion of the outer peripheral edge, wherein the outer peripheral edge further comprises a second portion that is an arch portion of the outer peripheral edge that extends for a length from the forefoot portion to the heel portion in a longitudinal direction of the sole, wherein a lateral side of the second portion is substantially perpendicular to the lower surface, wherein the lateral side of the second portion is substantially perpendicular substantially throughout the length of the second portion, wherein the heel portion comprises a lower portion having a substantially convex cross sectional profile shape, an upper portion having a substantially concave cross sectional profile shape, and a transition edge at which the substantially convex cross sectional profile shape of the lower portion transitions to the substantially concave cross sectional profile shape of the upper portion, and wherein the transition edge extends around a lateral side, a rear side, and a medial side of the heel portion. - View Dependent Claims (8, 9, 10)

11. An article of footwear, comprising:
-
a sole including an outer peripheral edge; and a lower surface of the sole configured to contact a ground surface, the outer peripheral edge comprising a first portion that is substantially curved and comprises one of a forefoot portion and a heel portion of the outer peripheral edge, wherein the outer peripheral edge further comprises a second portion that is an arch portion of the outer peripheral edge that extends for a length from the forefoot portion to the heel portion in a longitudinal direction of the sole, wherein a lateral side of the second portion is substantially perpendicular to the lower surface, wherein the lateral side of the second portion is substantially perpendicular substantially throughout the length of the second portion, wherein the outer peripheral edge includes an intermediate portion disposed between the first portion and the second portion, wherein the intermediate portion has a first cross sectional profile shape adjacent to the first portion and a second cross sectional profile shape adjacent to the second portion, wherein the second cross sectional profile shape is a substantially flat shape, wherein the first cross sectional profile shape comprises a lower portion having a substantially convex cross sectional profile shape, an upper portion having a substantially concave cross sectional profile shape, and a transition edge at which the substantially convex cross sectional profile shape of the lower portion transitions to the substantially concave cross sectional profile shape of the upper portion, and wherein the substantially convex cross sectional profile shape of the lower portion of the first cross sectional profile shape of the intermediate portion gradually increases in curvature moving in a direction toward the first portion of the outer peripheral edge, and wherein the substantially concave cross sectional profile shape of the upper portion of the first cross sectional profile shape of the intermediate portion gradually increases in curvature moving in a direction toward the first portion of the outer peripheral edge. - View Dependent Claims (12)
