A method of forming an article of footwear includes knitting a knitted component having a knit element and a tensile strand that are formed of unitary knit construction as a one-piece element. The knitted component is configured to at least partially form an upper for the article of footwear. The knit element defines a body and a trim region, and the trim region defines an outer edge of the knit element. The tensile strand includes at least one inlaid portion that is inlaid within the knit element. The tensile strand also includes an exposed portion that is exposed from the knit element and that is disposed adjacent the outer edge. The exposed portion is spaced from the outer edge in an inboard direction on the knit element. The method further includes manipulating the exposed portion to move and adjust the at least one inlaid portion relative to the knit element.
