Abstract
A method of manufacturing an article of footwear may include assembling at least a portion of an upper of the article of footwear, the upper having a lower perimeter edge. A lasting element is secured to the upper. The lasting element includes (a) a first strip joined to a lateral side of the upper adjacent to the lower perimeter edge, (b) a second strip joined to a medial side of the upper adjacent to the lower perimeter edge, and (c) at least one strand extending through the first strip and the second strip. The strand is tensioned, and a sole structure of the article of footwear is joined to the upper.
Claims23
A method of manufacturing an article of footwear, the method comprising:
- assembling at least a portion of an upper of the article of footwear, the upper having a lower perimeter edge;
- providing a lasting element that has been previously formed separately from the upper, the lasting element comprising:
- (a) a first strip, (b) a second strip spaced apart from the first strip, and (c) at least one strand extending through the first strip and the second strip;
- securing the lasting element to the upper, wherein securing the lasting element further comprises:
- (a) joining the first strip to a lateral side of the upper adjacent to the lower perimeter edge, (b) joining the second strip to a medial side of the upper adjacent to the lower perimeter edge, and (c) wherein the at least one strand is disposed through the first strip and the second strip so as to extend between the lateral side of the upper and the medial side of the upper;
- tensioning the at least one strand;
- and
- joining a sole structure of the article of footwear to the upper.
A method of manufacturing an article of footwear, the method comprising:
- placing at least a portion of an upper of the article of footwear over a last, the upper having a lower perimeter edge;
- providing a lasting element that has been previously formed separately from the upper, the lasting element comprising:
- (a) a first strip, (b) a second strip spaced apart from the first strip, and (c) at least one strand extending through the first strip and the second strip;
- securing the lasting element to the upper after the step of placing the upper over the last, wherein securing the lasting element further comprises:
- (a) joining the first strip to a lateral side of the upper adjacent to the lower perimeter edge, (b) joining the second strip to a medial side of the upper adjacent to the lower perimeter edge, and (c) wherein the at least one strand passes through the first strip and the second strip forming a w-shaped configuration between the first strip and the second strip so as to extend between the lateral side of the upper and the medial side of the upper;
- tensioning the strand to tighten the upper around the last;
- and
- joining a sole structure of the article of footwear to the upper.
A method of manufacturing an article of footwear, the method comprising:
- forming a lasting element of unitary knit construction, the lasting element including (a) a pair of textile strips and (b) at least one strand that passes through the textile strips and forms a w-shaped configuration between the textile strips, the unitary knit construction of the lasting element being such that the pair of textile strips and the at least one strand are a one-piece element;
- placing at least a portion of an upper of the article of footwear over a last, the upper being formed separately from the lasting element;
- securing the lasting element to the upper after the upper has been placed onto the last;
- tensioning the strand to tighten the upper around the last;
- and
- joining a sole structure of the article of footwear to the upper.
