US Patent 10327511: Shoe having knit wingtip upper

• Title: Shoe having knit wingtip upper
• Assignee: Cole Haan LLC
• Inventors: Jack Boys, Ann Bono, Aubert Shepherd, Mattias Verfl
• Filing Date: 2016-07-08
• Issue Date: 2019-06-25
• Abstract: A shoe includes a knit upper and a sole secured to the upper. The knit upper has a wingtip pattern knit into the knit upper.

Plain-Language Overview of Independent Claims:

• Claim 1 (Shoe with Knit Wingtip Pattern): This claim describes a shoe featuring a knit upper and a sole attached to it. The knit upper is constructed as a single, continuous piece formed during the knitting process. This knitted piece includes seamlessly integrated regions for the heel, lateral and medial midfoot, metatarsal, lateral and medial ball, and toe areas. A key characteristic is the presence of a wingtip pattern, which is also knitted into these regions. This wingtip pattern specifically includes distinct medial and lateral lines of broguing (lines of holes). These broguing lines are wing-shaped and curved, with side portions extending forward towards the toe and central portions extending rearward from the toe, converging towards each other.
• Claim 17 (Shoe with Knit Broguing and Different Knit Structures): This claim also describes a shoe with a knit upper and a sole, where the upper is a unitary one-piece knitted element with seamlessly integrated heel, midfoot, metatarsal, ball, and toe regions. The patent specifically highlights a line of broguing (a line of holes) knitted into the upper toe region. Additionally, the knitted element features at least two different types of knit structures: a first area of a first type of knit structure and a second area of a second, different type of knit structure. The first area is located at least in the upper toe region, and the second area is located at least in the upper lateral and medial metatarsal regions. The line of broguing is positioned adjacent to the rear boundary of the first area and the forward boundary of the second area.
• Claim 20 (Method of Manufacturing an Upper with Broguing and Different Knit Structures): This claim outlines a manufacturing method for a footwear upper. The method involves knitting a single, continuous piece for the upper, including the heel, midfoot, metatarsal, ball, and toe regions, which are all seamlessly knitted together. During this knitting step, a line of broguing (holes) is incorporated into the upper, particularly in the toe region. Furthermore, the knitting process creates a first area with a first type of knit structure and a second area with a second, different type of knit structure, located at least in the toe region and the lateral and medial metatarsal regions, respectively. The line of broguing is formed adjacent to the boundaries of these two knit areas.
• Claim 21 (Method of Manufacturing a Shoe with Specific Knit Structures and Sole Attachment): This claim describes a method for manufacturing an entire shoe. It involves knitting a unitary one-piece upper that includes seamlessly knitted heel, midfoot, metatarsal, ball, and toe regions. Specifically, the knitted element is formed with a first area using a jersey stitch knit (at least in the upper toe region) and a second area using a pointelle stitch knit (at least in the upper lateral and medial metatarsal regions). After the knitting step, the method includes attaching the sole to the upper. The seamless knitting of the various regions and the knitting of the distinct jersey and pointelle stitch areas all occur during the initial knitting process.
