A method of forming an article of footwear includes knitting a knitted workpiece formed of unitary knit construction. The knitted workpiece is configured to at least partially form an upper of the article of footwear. The knitted workpiece has a body and a trim region. The trim region defines at least a portion of an outer edge of the knitted workpiece. A first dimension of the knitted workpiece is at least partly defined by the outer edge. The method also includes heating the knitted workpiece. Also, the method includes trimming the knitted workpiece within the trim region after heating the knitted workpiece to remove a piece from the knitted workpiece and to reduce the first dimension to a second dimension. Also, the method includes forming the upper from the trimmed knitted workpiece.

1. A method of forming an article of footwear comprising: knitting a knitted workpiece formed of unitary knit construction, the knitted workpiece configured to at least partially form an upper of the article of footwear, the knitted workpiece having a body and a trim region, the trim region defining at least a portion of an outer edge of the knitted workpiece, a first dimension of the knitted workpiece defined at least partly by the outer edge;heating the knitted workpiece;trimming the knitted workpiece within the trim region after heating the knitted workpiece to remove a piece from the knitted workpiece and to reduce the first dimension to a second dimension; andforming the upper from the trimmed knitted workpiece. 2. The method of claim 1, further comprising attaching a skin layer to the knitted workpiece. 3. The method of claim 2, wherein attaching the skin layer occurs after heating the knitted workpiece and before trimming the knitted workpiece. 4. The method of claim 1, wherein knitting the knitted workpiece includes knitting the knitted workpiece with at least one fusible strand. 5. The method of claim 1, wherein knitting the knitted workpiece includes knitting the knitted workpiece to include a knit element and a tensile strand, the tensile strand including at least one inlaid portion that is inlaid within the knit element, the tensile strand also including an exposed portion that is exposed from the knit element, wherein the exposed portion is spaced from the outer edge in an inboard direction on the knitted workpiece, and further comprising pulling on the exposed portion to move and adjust the at least one inlaid portion relative to the knit element. 6. The method of claim 5, wherein the at least one inlaid portion includes a first inlaid portion and a second inlaid portion, and wherein the exposed portion extends continuously between the first inlaid portion and the second inlaid portion. 7. The method of claim 5, wherein knitting the knitted workpiece includes forming the outer edge with a first layer and a second layer formed of unitary knit construction, the first layer and the second layer overlaying each other and connected in the body, the first layer and the second layer overlaying each other and disconnected in the trim region, and wherein knitting the knitted workpiece includes disposing the exposed portion of the tensile strand between the first layer and the second layer in the trim region. 8. The method of claim 5, wherein knitting the knitted workpiece includes knitting the knitted workpiece with a first layer and a second layer formed of unitary knit construction, the first layer and the second layer overlaying each other and connected in the body, the first layer extending further in an outboard direction on the knitted component than the second layer to define the trim region and the outer edge, and wherein knitting the knitted workpiece includes disposing the exposed portion of the tensile strand on the first layer within the trim region. 9. The method of claim 1, further comprising fixing a first area of the knitted workpiece to a support surface and fixing a second area of the knitted workpiece to the support surface before heating the knitted workpiece, the first area and the second area being spaced from each other along the outer edge, wherein an indentation is formed in the outer edge between the first area and the second area, and wherein trimming the knitted workpiece includes removing the indentation from the knitted workpiece. 10. The method of claim 1, further comprising selecting whether to form the article of footwear to fit a first foot size or a second foot size, wherein trimming the knitted workpiece includes trimming the knitted workpiece along a first trim line when selecting to form the article of footwear to fit the first foot size, and wherein trimming the knitted workpiece includes trimming the knitted workpiece along a second trim line when selecting to form the article of footwear to fit the second foot size, the second trim line being spaced from the first trim line in an inboard direction on the knitted workpiece. 11. A method of forming an article of footwear that is configured to fit one of a first foot size and a second foot size, the first foot size being larger than the second foot size, the method comprising: selecting whether to form the article of footwear to fit the first foot size or the second foot size;providing a knitted workpiece formed of unitary knit construction, the knitted workpiece including a body and a trim region, wherein providing the knitted workpiece includes knitting to form the knitted workpiece having a knit element and a tensile strand, the tensile strand including at least one inlaid portion that is inlaid within the knit element, the tensile strand also including an exposed portion that is exposed from the knit element, wherein the exposed portion is spaced from an outer edge of the knitted workpiece in an inboard direction on the knitted workpiece, and further comprising pulling on the exposed portion to move and adjust the inlaid portion relative to the knit element; andtrimming the knitted workpiece within the trim region to form a first trimmed piece;wherein trimming the knitted workpiece includes forming a first trimmed piece upon selecting to form the article of footwear to fit the first foot size,wherein trimming the knitted workpiece includes forming a second trimmed piece upon selecting to form the article of footwear to fit the second foot size, andwherein the first trimmed piece is configured to form a first upper that fits the first foot size, and the second trimmed piece is configured to form a second upper that fits the second foot size. 12. The method of claim 11, further comprising heating the knitted workpiece. 13. The method of claim 11, further comprising attaching a skin layer to the knitted workpiece. 14. The method of claim 11, wherein providing the knitted workpiece includes knitting the knitted workpiece. 15. The method of claim 14, wherein knitting the knitted workpiece includes knitting at least one fusible strand to at least partially form the knitted workpiece. 16. The method of claim 11, wherein providing the knitted workpiece includes flat knitting the knitted workpiece such that the knitted workpiece is a flat knitted workpiece. 17. The method of claim 11, wherein the at least one inlaid portion includes a first inlaid portion and a second inlaid portion, and wherein the exposed portion extends continuously between the first inlaid portion and the second inlaid portion. 18. The method of claim 11, wherein providing the knitted workpiece includes knitting the knitted workpiece to include a first layer and a second layer formed of unitary knit construction, the first layer and the second layer overlaying each other and connected in the body, the first layer and the second layer overlaying each other and disconnected in the trim region, and wherein knitting the knitted workpiece includes disposing the exposed portion of the tensile strand between the first layer and the second layer in the trim region. 19. The method of claim 11, wherein providing the knitted workpiece includes knitting the knitted workpiece to include a first layer and a second layer formed of the unitary knit construction, the first layer and the second layer overlaying each other and connected in the body, the first layer extending further in an outboard direction on the knitted component than the second layer to define the trim region and the outer edge, and wherein knitting the knitted workpiece includes disposing the exposed portion of the tensile strand on the first layer within the trim region.
