10. The article of footwear recited in claim 8 , wherein edges of the first knitted layer are secured to edges of the second knitted layer along opposite sides of the central area to define the tubular structure.

11. The article of footwear recited in claim 10 , wherein the first knitted layer and the second knitted layer are unsecured to each other through the central area of the tongue to form an interior volume within the tubular structure.

12. The article of footwear recited in claim 11 , wherein the plurality of free yarn sections are configured to fill the interior volume within the tubular structure.

13. The article of footwear recited in claim 8 , wherein at least one of the first knitted layer and the second knitted layer includes a stretch yarn.

14. The article of footwear recited in claim 8 , wherein the tongue further comprises peripheral areas disposed along each of a lateral edge and a medial edge of the tongue, the lateral edge and the medial edge of the tongue being unsecured to the knit element along a medial side and a lateral side of the throat area of the upper.

15. The article of footwear recited in claim 14 , wherein the tongue further comprises at least two areas having knit apertures disposed between the central area and the peripheral areas and spaced apart from the lateral edge and medial edge of the tongue.

16. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper, the interior surface defining a void for receiving a foot, the knit element having opposite inner edges on a medial side and a lateral side that are spaced apart from each other to define a throat area extending along a longitudinal direction of the upper; and

a tongue formed of unitary knit construction with the knit element such that the tongue and the knit element comprise a one piece element, and wherein the tongue extends through the throat area of the upper;

wherein the tongue comprises a lateral edge and a medial edge, the lateral edge and the medial edge of the tongue being secured to the knit element at a location that is spaced outward from each of the inner edges along the medial side and the lateral side of the throat area of the upper; and

wherein the tongue is secured to the knit element in a forward portion of the throat area such that the tongue is joined along at least one common course with the knit element to form the one-piece element.

17. The article of footwear recited in claim 16 , wherein at least a portion of the tongue includes a plurality of knit apertures.

18. The article of footwear recited in claim 16 , wherein the knit element includes at least one course that is substantially continuous with at least one course of the tongue at the forward portion of the throat area of the upper; and
