A method of manufacturing an article of footwear, the method comprising: warp knitting a knit element formed of unitary knit construction, the knit element having a warp direction and a weft direction, the knit element comprising a plurality of strap members that are configured to be substantially non-extensible along the warp direction for providing support to the article of footwear; and forming at least part of an upper of the article of footwear from the knit element; wherein warp knitting the knit element includes warp knitting the plurality of strap members to include at least a first strap member and a second strap member, each of the first strap member and the second strap member including a leading edge (51, 55) and an opposite trailing (53, 57) edge; wherein warp knitting the knit element further includes warp knitting the first strap member and the second strap member to be: separated along a portion of a length of the first and second strap members (28, 30) by a slit, and (ii) at least partially joined through knitting at a junction (32, 34); wherein warp knitting the first strap member includes warp knitting a first leading edge and a first trailing edge of the first strap member, the first trailing edge extending from the junction generally in the warp direction; wherein warp knitting the second strap member includes warp knitting a second leading edge and a second trailing edge of the second strap member, the second leading edge extending from the junction generally in the warp direction, the second leading edge and the first trailing edge cooperating to define the slit that separates the first strap member and the second strap member. warp knitting a knit element formed of unitary knit construction, the knit element having a warp direction and a weft direction, the knit element comprising a plurality of strap members that are configured to be substantially non-extensible along the warp direction for providing support to the article of footwear; and forming at least part of an upper of the article of footwear from the knit element; wherein warp knitting the knit element includes warp knitting the plurality of strap members to include at least a first strap member and a second strap member, each of the first strap member and the second strap member including a leading edge (51, 55) and an opposite trailing (53, 57) edge; wherein warp knitting the knit element further includes warp knitting the first strap member and the second strap member to be: separated along a portion of a length of the first and second strap members (28, 30) by a slit, and (ii) at least partially joined through knitting at a junction (32, 34); wherein warp knitting the first strap member includes warp knitting a first leading edge and a first trailing edge of the first strap member, the first trailing edge extending from the junction generally in the warp direction; wherein warp knitting the second strap member includes warp knitting a second leading edge and a second trailing edge of the second strap member, the second leading edge extending from the junction generally in the warp direction, the second leading edge and the first trailing edge cooperating to define the slit that separates the first strap member and the second strap member.
