Article of Footwear Having An Upper Incorporating A Knitted Component

摘要

An article of footwear has an upper that includes a knitted component and a sole structure secured to the upper. The knitted component may define a tube formed of unitary knit construction, and a strand may extend through a length of the tube. As another example, the knitted component may have a pair of at least partially coextensive knitted layers formed of unitary knit construction, and a plurality of floating yarns may extend between the knitted layers. In some configurations, the knit type or yarn type may vary in different regions of the knitted component to impart different properties. Additionally, the knitted component may incorporate a thermoplastic yarn that is fused in different regions of the knitted component to impart different properties. A flat knitting process or a variety of other knitting processes may be utilized to form the knitted component.

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:
a knitted component formed of unitary knit construction, the knitted component comprising a first knitted layer and a second knitted layer that are at least partially coextensive with each other, the knitted component including a plurality of tubular structures, the plurality of tubular structures comprising the first knitted layer and the second knitted layer that are overlapping and joined to each other along opposite edges to define sides of a first tube and a second tube, the first tube and the second tube being formed by the first knitted layer and the second knitted layer to have unitary knit construction so as to be a one-piece element with the remaining portion of the knitted component; and a strand extending through the first tube and the second tube, a portion of the strand extending between a first end of the first tube and a first end of the second tube to form a loop; wherein the first end of the first tube and the first end of the second tube are separated at a first distance; and wherein a second end of the first tube and a second end of the second tube area are separated at a second distance, wherein the second distance is greater than the first distance.
