Abstract

An article of footwear may include an upper and a sole structure secured to the upper. The upper has a knitted component formed of unitary knit construction that includes at least one gore region located in a heel region of the article of footwear. The gore region provides a contoured configuration to the knitted component. In a method of manufacturing, a knitted component may include a first gore region and a plurality of second gore regions, with the first gore region being located in a heel area of the article of footwear and the second gore regions being located adjacent to the sole structure.

Claims

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising a knitted component that includes at least one gore region located in a heel region of the article of footwear;

wherein the heel region comprises a top edge and a bottom edge and wherein the at least one gore region extends vertically through a majority of a distance from the bottom edge towards the top edge, and a plurality of spaced apart second gore regions;

wherein at least one of the plurality of second gore regions is located on one of a medial side and a lateral side of the first gore region, and another of the plurality of second gore regions is located on the other of the medial side and a lateral side of the first gore region; and

wherein each of the plurality of second gore regions extend vertically from the bottom edge towards the top edge, and

wherein the at least one gore region and the plurality of second gore regions are spaced apart from each other and each include a vertical center midline, and wherein the at least one gore region and the plurality of second gore regions includes a first series of courses of increasing length in a direction towards the midline and a second series of courses of decreasing length in a direction away from the midline.

2. The article of footwear recited in claim 1, wherein the at least one gore region is larger than each of the plurality of second gore regions.

3. The article of footwear recited in claim 2, wherein the at least one gore region extends through a majority of a distance between the bottom edge and the top edge of the heel region, and the plurality of second gore regions extend through less than one-third of the distance between the bottom edge and the top edge of the heel region.

4. The article of footwear recited in claim 2, wherein the second gore regions form a series of gores extending upwards from the bottom edge of the heel region.

5. The article of footwear recited in claim 1, wherein the upper includes a forward knitted component located in at least a forefoot region of the article of footwear, the forward knitted component and the heel region being joined together and forming a majority of the upper.
