Knitted shoe upper

This invention describes a shoe upper, like the top part of a sneaker, that is made from a single piece of knitted fabric. It features two distinct zones: one area is made with an elastic yarn to provide stretch, running continuously across the shoe, while an adjacent area uses a different yarn and/or knit pattern to be less stretchy, offering support. This design aims to combine flexibility and support in one seamless knitted piece.

Why it matters: Since 2014, industrial knitting technology has advanced significantly, allowing for more precise control over complex knit structures and the seamless integration of diverse yarns with varying elastic properties into a single piece. This enables more sophisticated functional zones in knitted footwear uppers.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIndustrial knitting machinery, specialized yarns, coating process.
