Knitted component with containment

Abstract

An article of footwear comprising a knitted component and a containment piece are disclosed. The containment piece can be a textile element that in some aspects is also knitted. The containment piece is provided on a medial side of the article of footwear, where one end of the containment piece is secured to the sole structure, and the other end is secured to the knitted component via one or more containment piece lacing loops and one or more lacing loops of the knitted component. The one or more lacing loops of the knitted component and the one or more containment piece lacing loops can be formed from an inlaid tensile strand. A method of manufacturing the knitted component and the containment piece is also described herein.

What is claimed is: 
     
         1 . An article of footwear comprising:
 an upper including a knitted component forming at least a medial side of the upper;   a containment piece overlapping a portion of the medial side of the upper, the containment piece having a first edge and a second edge opposite the first edge; and   a sole structure comprising a slit;   wherein the containment piece is secured to the knitted component proximate the first edge of the containment piece, and   wherein a portion of the containment piece proximate the second edge of the containment piece is inserted through the slit of the sole structure.   
     
     
         2 . The article of footwear of  claim 1 , wherein the containment piece comprises a tapered shape such that the first edge of the containment piece is longer than the second edge of the containment piece. 
     
     
         3 . The article of footwear of  claim 1 , wherein the knitted component comprises a continuous inlaid tensile strand forming a plurality of lacing loops. 
     
     
         4 . The article of footwear of  claim 1 , wherein the containment piece includes an inlaid tensile strand forming at least one containment piece lacing loop, wherein the first edge of the containment piece is secured to a throat area of the article of footwear by the at least one containment piece lacing loop. 
     
     
         5 . The article of footwear of  claim 1 , wherein the knitted component comprises a first yarn, and wherein the containment piece comprises a second yarn that is a different material than the first yarn. 
     
     
         6 . The article of footwear of  claim 5 , wherein the knitted component comprises an inlaid tensile strand forming a plurality of lacing loops, wherein a first tensile strength of the inlaid tensile strand is greater than a second tensile strength of the second yarn, and wherein the second tensile strength of the second yarn is greater than a third tensile strength of the first yarn. 
     
     
         7 . The article of footwear of  claim 1 , wherein the second edge of the containment piece is further secured to the sole structure by one or more of: adhesive bonding, fusing, and stitching. 
     
     
         8 . The article of footwear of  claim 1 , wherein the containment piece is configured to align with an arch of a foot of a wearer when the article of footwear is worn by the wearer. 
     
     
         9 . The article of footwear of  claim 1 , wherein the containment piece is unsecured to the upper between the first edge and the second edge of the containment piece. 
     
     
         10 . An article of footwear comprising:
 an upper including a knitted component forming a medial side and/or a lateral side of the upper;   a sole structure; and   at least one containment piece secured to the sole structure and wrapping over at least a portion of the sole structure and at least a portion of the knitted component.   
     
     
         11 . The article of footwear of  claim 10 , wherein the at least one containment piece overlaps at least a portion of the medial side of the upper. 
     
     
         12 . The article of footwear of  claim 10 , wherein the at least one containment piece overlaps at least a portion of the lateral side of the upper. 
     
     
         13 . The article of footwear of  claim 10 , wherein the at least one containment piece comprises a tapered shape such that a first edge of the containment piece is longer than a second edge of the containment piece that is located opposite to the first edge. 
     
     
         14 . The article of footwear of  claim 13 , wherein the at least one containment piece is secured to the sole structure proximate the second edge of the at least one containment piece. 
     
     
         15 . The article of footwear of  claim 13 , wherein the at least one containment piece is secured to the sole structure proximate the first edge of the at least one containment piece. 
     
     
         16 . The article of footwear of  claim 10 , wherein the at least one containment piece is secured to the knitted component includes an inlaid tensile strand forming at least one containment piece lacing loop, and wherein the at least one containment piece is secured to a throat area of the article of footwear by the at least one containment piece lacing loop. 
     
     
         17 . The article of footwear of  claim 10 , wherein the at least one containment piece includes a first edge and a second edge that is positioned superior to the first edge, and wherein the at least one containment piece is unsecured to the upper between the first edge and the second edge of the containment piece. 
     
     
         18 . A method for manufacturing an article of footwear, comprising:
 knitting a knitted component for an upper having a medial side;   knitting a containment piece, the containment piece having a first edge and a second edge opposite the first edge;   inserting the second edge of the containment piece through a slit of a sole structure and securing the containment piece to the sole structure; and   securing the sole structure to the upper.   
     
     
         19 . The method of  claim 18 , wherein the containment piece comprises a tapered shape such that the second edge of the containment piece is shorter than the first edge of the containment piece. 
     
     
         20 . The method of  claim 19 , wherein the containment piece is unsecured to the upper between the first edge and the second edge of the containment piece.
