Upper for an article of footwear with at least one strand for lasting
The present disclosure provides a knitted component, the knitted component with a knit element that forms at least a portion of an upper for an article of footwear and defines an interior void for receiving a foot. A lower perimeter edge of the knit element may extend between a lateral side and a medial side of the upper. At least one strand of the knitted component may extend through the lower perimeter edge on opposite sides of the knitted component so as to extend between the lateral side and the medial side of the upper. The knitted component may be formed on a knitting machine, and the at least one strand may be configured to be tensioned to tighten the upper around a last.
1. An upper for an article of footwear, the upper comprising:
a first knit element formed with a knitted material and defining an exterior surface of the upper, wherein the first knit element includes a lower perimeter edge located adjacent at an underfoot portion of the first knit element; and
a second knit element that is knit separately from the first knit element, the second knit element being formed with a knitted material, and the second knit element defining a lasting element, the lasting element including:
a first knitted strip joined to the lower perimeter edge on a first side of the upper;
a second knitted strip joined to the lower perimeter edge on a second side of the upper, the second side being opposite the first side; and
at least one strand extending through the first knitted strip and the second knitted strip,
wherein the at least one strand is configured to be tensioned to cause the lasting element to tighten the knit element around a last.
2. The upper of claim 1 , wherein the first side is a lateral side of the upper and wherein the second side is a medial side of the upper.
3. The upper of claim 1 , wherein the at least one strand passes through the opposite sides such that it forms a w-shaped configuration between the opposite sides.
4. The upper of claim 1 , wherein tensioning the at least one strand causes drawing of the opposite sides closer together along the entire length of the first knit element.
5. The upper of claim 1 , wherein the first and second knitted strips are joined to the lower perimeter edge of the first knit element via at least one of stitching, thermal bonding, and adhesive bonding.
6. The upper of claim 1 , wherein at least one of the first knitted strip, the second knitted strip, and the lower perimeter edge of the first knit element is configured to secure to a sole structure of an article of footwear.
7. The upper of claim 1 , wherein the at least one strand alternates between the opposite sides of the upper along an entirety of a length of the upper.
