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.

The article of footwear recited in claim 2, wherein the first knitted layer, the second knitted layer, and the floating yarns are located on a medial side of the upper and a lateral side of the upper. 4. The article of footwear recited in claim 3, wherein the collar extends around the ankle opening through at least a portion of the medial side and the lateral side; and wherein the single layer of the knitted component comprising the interior surface and the exterior surface of the upper extends around the medial side and the lateral side of the upper beneath the collar. 5. The article of footwear recited in claim 1, wherein a first area of the knitted component has a first knit type and a second area of the knitted component has a second knit type, the first knit type being different than the second knit type. 6. The article of footwear recited in claim 1, wherein a first area of the knitted component has a first yarn type and a second area of the knitted component has a second yarn type, the first yarn type being different than the second yarn type. 7. 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 that includes: a unitary layer comprising an interior surface of the upper and an opposite exterior surface of the upper;the unitary layer extending from the sole structure towards a collar disposed at least partially around an ankle opening of the upper;the collar comprising:a first knitted layer and a second knitted layer, the first knitted layer being at least partially coextensive with the second knitted layer to define a tube having an interior volume between the first knitted layer and the second knitted layer;a plurality of floating yarns located within the interior volume and extending through the tube at least partially around the ankle opening in a direction that is substantially parallel to the first knitted layer and the second knitted layer; andwherein the tube formed by the first knitted layer and the second knitted layer has a unitary knit construction so as to be a one-piece element with the upper. 8. The article of footwear recited in claim 7, wherein the upper defines an interior void for receiving a foot; and wherein the ankle opening provides access to the interior void and wherein the interior surface of the unitary layer is exposed to the interior void. 9. The article of footwear recited in claim 8, wherein the collar, including the first knitted layer, the second knitted layer, and the floating yarns, are located along a medial side of the upper, along a lateral side of the upper, and extend around a heel region of the upper. 10. An article of footwear having an upper and a sole structure secured to the upper, the upper defining an interior void for receiving a foot of a wearer, and the upper having an ankle opening that provides access to the void, the upper comprising a knitted component that includes: a first portion comprising an interior surface of the upper and an opposite exterior surface of the upper extending between the sole structure of the article of footwear to a location spaced apart from the ankle opening; anda second portion comprising a collar extending at least partially around the ankle opening;wherein the collar comprises:a first knitted layer forming at least a portion of the exterior surface of the upper adjacent to the ankle opening;a second knitted layer forming at least a portion of the interior surface of the upper adjacent to the ankle opening; anda plurality of floating yarns located between the first knitted layer and the second knitted layer,wherein the first knitted layer and the second knitted layer are joined to each other along a top of the ankle opening and at the location spaced from the ankle opening to define a separated area therebetween, and the floating yarns are located in the separated area and extend along the collar at least partially around the ankle opening; andwherein the first knitted layer and the second knitted layer have a unitary knit construction so as to be a one-piece element with the upper. 11.
