Flat knitting allows production of textile structures (e.g., for use in footwear uppers) of a final desired shape such that textile cutting steps can be avoided. Flat knitted elements also can be formed directly in desired three dimensional shapes, which can help avoid the need to use additional support structures (e.g., in footwear construction). By selectively placing multiple different yarns and/or stitch patterns at multiple different locations in the overall structure during the knitting process, flat knitted products may have multiple different physical properties (e.g., different stretchability, different moisture management capabilities, etc.) at multiple different locations or zones within a single, unitary construction (e.g., different properties at different zones or locations within a single footwear structure). Additionally, flat knitting can be used to produce pockets, tunnels, or other layered structures in the final product.

1. An article of footwear comprising an upper including a flat-knitted element formed from at least one yarn mechanically manipulated in a flat-knitting process, the flat-knitted element including a first layer having: a central portion having a domed, three-dimensional structure configured for extending over the top of a foot;a first side portion being formed of unitary construction with the central portion and extending from a first side of the central portion; anda second side portion being formed of unitary construction with the central portion and extending from a second side opposite the first side of the central portion, the domed, three-dimensional structure shaped to extend above the plane of the first side portion and the second side portion when the flat-knitted element is in a flattened configuration. 2. The article of footwear of claim 1, further comprising a first loop being formed as a second layer of unitary construction with the first layer. 3. The article of footwear of claim 2, wherein the first loop extends outward from the central portion. 4. The article of footwear of claim 2, further comprising eight loops being formed as a second layer of unitary construction with the first layer. 5. The article of footwear of claim 1, wherein the knitted element defines a void for receiving a foot of a wearer. 6. The article of footwear of claim 1, wherein the knitted element defines at least a portion of an exterior surface of the upper, and the knitted element defines at least a portion of a void for receiving a foot of a wearer. 7. The article of footwear of claim 1, wherein the knitted element includes a first area and a second area, the first area including a first type of knit structure, and the second area including a second type of knit structure, the first type being different than the second type. 8. The article of footwear of claim 1, wherein the at least one mechanically manipulated yarn includes a first yarn and a different second yarn, the first yarn being located in a first area of the upper, and the second yarn being located in a second area of the upper. 9. The article of footwear of claim 1, wherein the knitted element forms a defined shape having finished edges during the flat knitting process. 10. An article of footwear comprising an upper including a flat-knitted element formed from at least one yarn mechanically manipulated in a flat-knitting process, the flat-knitted element including a first layer and a second layer, the first layer including: a central portion having a domed, three-dimensional structure configured for extending over the top of a foot;a first side portion being formed of unitary construction with the central portion and extending from a first side of the central portion; anda second side portion being formed of unitary construction with the central portion and extending from a second side opposite the first side of the central portion; andthe second layer being flat-knitted with the first layer at opposite ends of the second layer to form an overlapped loop. 11. A method of manufacturing an article of footwear, the method comprising forming during a flat-knitting process an upper including a flat-knitted element including a first layer having: a central portion having a domed, three-dimensional structure configured for extending over the top of a foot;a first side portion being formed of unitary construction with the central portion and extending from a first side of the central portion; anda second side portion being formed of unitary construction with the central portion and extending from a second side opposite the first side of the central portion, wherein the domed, three-dimensional structure is shaped to extend above the plane of the first side portion and the second side portion when the flat-knitted element is in a flattened configuration. 12. The method recited in claim 11, wherein the flat knitting process includes forming a first area and a second area, a stitch type of the first area being different that a stitch type of the second area. 13. The method recited in claim 11, wherein the flat knitting process includes forming a first area and a second area, a yarn type of the first area being different than a yarn type of the second area. 14. The method recited in claim 11, wherein the flat knitting process includes forming a first area and a second area, a stitch type and a yarn type of the first area being different than a stitch type and a yarn type of the second area. 15. The method recited in claim 11, further comprising assembling the flat-knitted element into an article of footwear. 16. The method recited in claim 15, wherein the assembling includes joining side edges of the first side portion and the second side portion to form a seam extending under a foot and along a longitudinal length of the foot. 17. The method recited in claim 15, wherein the assembling includes joining rear edges of the first side portion and the second side portion to form a seam that extends upward along a heel. 18. The method recited in claim 11, wherein the flat knitting process includes forming a first loop of unitary construction in the textile element. 19. The method recited in claim 18, further comprising extending a lace element through the first loop.
