Embodiment Construction

[0010] Embodiments of the present disclosure include articles of footwear including circular knits formed into the double knit upper of article of footwear 10 . Article of footwear 10 is disclosed as having a configuration suitable for walking or running. The concepts associated with footwear can also be applied to a variety of other athletic shoe types, including, for example, baseball, basketball, cross-training, cycling, soccer, tennis, football, sprinting, and hiking shoes. The concepts can also be applied to footwear that is typically considered non-athletic, including dress shoes, loafers, sandals, and work boots. The concepts disclosed in this application are applicable to various types of footwear.

[0011] refer to Figures 1 to 3 , the article of footwear 10 includes a sole component 20 and an upper knit component 30 . For reference purposes, article of footwear 10 may be divided into three general regions: forefoot region 11 , midfoot region 12 behind the forefoo...

Abstract

An aspect of the disclosure is a footwear article (10). The footwear article (10) includes a double layer knitted upper having a foot bed (41), an upper portion (144A, 244A) continuous with the foot bed (41), an ankle opening (32), and an inner void (31) for receiving a foot of a wearer. The double layer knitted upper has an outer knit layer (60) defining an exterior surface (50) of the double layer knitted upper. The double layer knitted upper also has an inner knit layer (80) monolithically knit to the outer knit layer (60). The inner knit layer (80) has a plurality of inner knit regions (82A) that spatially correspond to the plurality of outer knit regions (62A) of the outer knit layer (60). The outer knit layer (60) and the inner knit layer (80) substantially define the foot bed (41) and the upper portion (144A, 244A) of the double layer knitted upper.

Description

technical field [0001] The present disclosure relates to an article of footwear comprising a circular knit structure and a method of making such an article of footwear. Background technique [0002] A traditional article of footwear has a sole and an upper attached to the sole. Footwear manufacturing has historically been a labor-intensive cutting and stitching assembly operation. Sheets of upper material are cut to size and sewn together to form the upper. The sole is attached to the upper using a number of different techniques to form the finished article of footwear. Recent developments in footwear design employ knitting techniques to form parts of footwear and, in particular, uppers. In some cases, flat bed knitting is used to form flat knit fabric blanks. The jersey blank is formed into a specific shape so that it can be folded or wrapped into a near-finished upper. Once the upper is formed, a sole assembly or other durable structure is attached to the knitted uppe...
