Article of footwear having heel portion with knitted component
First Claim
1. An article of footwear comprising:
- a sole structure; and
an upper having a longitudinal axis, wherein the upper is coupled to the sole structure, the upper including a lower edge that is disposed adjacent to the sole structure, the upper further including;
a collar having an upper peripheral edge defining an opening to a void within the upper;
a forward portion and a heel portion;
wherein the collar circumferentially surrounds the entire opening to the void when the forward portion and heel portion are assembled into the upper, the collar defined by the upper peripheral edge and a lower boundary uniformly spaced from the upper peripheral edge;
the heel portion comprising a knitted component of unitary knit construction, wherein the knitted component of the heel portion has a single uninterrupted first zone and a single uninterrupted second zone, wherein the first zone has a first amount of stretch resistance and the second zone has a second amount of stretch resistance, and wherein the first amount of stretch resistance of the first zone is larger than the second amount of stretch resistance of the second zone, wherein the second zone is located rearwardly of the opening to the void of the upper and substantially centered on the longitudinal axis and substantially centered within the first zone;
wherein the second zone abuts the collar on one side and wherein all other sides of the second zone are surrounded by the first zone;
wherein the collar comprises a third amount of stretch resistance and wherein the third amount of stretch resistance of the collar is less than the second amount of stretch resistance of the second zone; and
wherein the knitted component includes a first side edge that is attached to the forward portion along a first side and a second side edge that is attached to the forward portion along a second side.

Abstract
An article of footwear includes a sole structure and an upper coupled to the sole structure. The upper includes a lower edge that is disposed adjacent to the sole structure. The upper further includes a collar defining an opening to a void within the upper. The collar defines an upper edge of the upper that is spaced away from the lower edge. The upper includes a forward portion and a heel portion. The heel portion includes a knitted component of unitary knit construction. The knitted component at least partially defines the upper edge and the lower edge of the upper. The knitted component includes a first side edge that is attached to the forward portion along a first side. The knitted component also includes a second side edge that is attached to the forward portion along a second side.

11. An article of footwear comprising:
-
a sole structure; and an upper coupled to the sole structure, the upper comprising; a forward portion formed of a first component and a heel portion formed of a second component, the first component being separate from the second component; the forward portion and the heel portion being joined to each other along at least one seam; a collar portion circumferentially surrounding an opening to a void formed by the upper when the forward portion and heel portion are joined, the collar having an upper peripheral edge and a lower boundary that is uniformly spaced from and concentric with the upper peripheral edge; the heel portion comprising a heel knitted component of unitary knit construction, the heel knitted component having a first uninterrupted knitted zone associated with a first amount of stretch resistance and a second uninterrupted knitted zone associated with a second amount of stretch resistance;
wherein the second knitted zone is located rearwardly of the opening to the void of the upper, andwherein the first amount of stretch resistance of the first knitted zone is larger than the second amount of stretch resistance of the second knitted zone; and
wherein the second zone abuts the collar on one side and wherein all other sides of the second zone are surrounded by the first zone. - View Dependent Claims (12, 13, 14, 15, 16, 17)
