Upper for an article of footwear and method of lasting the upper

Abstract

In one aspect, the present disclosure provides a method. The method may include placing an upper on a last, where the upper includes a lower perimeter edge secured to a lasting element, and where the last includes an opening for receiving the lasting element. The method may further include feeding the lasting element at least partially through an opening of the last and tensioning the lasting element to tighten the upper around the last by pulling the tensioning element at least partially through the opening.

         9 . The article of footwear of  claim 5 , wherein the at least one opening comprises a plurality of openings located about the passage, and wherein the lasting element extends between the plurality of openings such that the lasting element extends across an underfoot portion. 
     
     
         10 . The article of footwear of  claim 9 , wherein the lasting element comprises a first segment that extends across the underfoot portion and a second segment that extends across the underfoot portion, wherein the first segment and the second segment intersect. 
     
     
         11 . An upper, comprising:
 a knitted component, comprising:
 an inner perimeter edge; 
 an outer perimeter edge; 
 a passage within the knitted component, the passage extending about the knitted component adjacent to the outer perimeter edge, the passage comprising a first end and a second end; and 
 a lasting element extending through the passage, wherein the lasting element is exposed at a plurality of openings in the passage, the plurality of openings located between the first end and the second end. 
   
     
     
         12 . The upper of  claim 11 , wherein the plurality of openings comprise a first opening located on a first side of the upper and a second opening located on a second side of the upper, the lasting element extending between the first opening and the second opening outside of the passage. 
     
     
         13 . The upper of  claim 11 , wherein the lasting element comprises a strip. 
     
     
         14 . The upper of  claim 11 , wherein the lasting element comprises a strand. 
     
     
         15 . The upper of  claim 14 , wherein the strand comprises at least one of a filament, a fiber, a thread, a yarn, a cable, and a rope. 
     
     
         16 . The upper of  claim 11 , wherein the lasting element extends between the plurality of openings such that the lasting element intersects itself outside of the passage. 
     
     
         17 . An article of footwear, comprising:
 an upper, comprising:
 a knitted component, comprising: 
 an inner perimeter edge; 
 an outer perimeter edge; 
 a channel that extends about the upper adjacent to the outer perimeter edge; and 
 a lasting element extending at least partially through the channel; and 
 a sole structure attached to the upper without a strobel. 
   
     
     
         18 . The article of footwear of  claim 17 , wherein the channel comprises a plurality of openings spaced about a length of the channel at which the lasting element is exposed. 
     
     
         19 . The article of footwear of  claim 18 , wherein the plurality of openings comprises a first plurality of openings located on a first side of the upper and a second plurality of openings located on a second side of the upper.
