This invention describes a method for making a complete shoe upper using an automated knitting machine with multiple needle beds. It knits the entire upper, including an integrated heel and potentially a sole, as a single, seamless piece, eliminating the need for cutting or sewing after knitting. The process involves knitting and manipulating an insert and moving stitches to create the three-dimensional shape.
Why it matters: Since 2021, advancements in knitting machine software and automation may have simplified the complex programming required for intricate 3D structures. This could make the seamless, integrated manufacturing process more efficient or accessible.
