Definitions

  • Conventional articles of footwear generally include two primary elements, an upper and a sole structure.
  • the upper and the sole structure at least in part, define a foot-receiving chamber that may be accessed by a user's foot through a foot-receiving opening.
  • the upper is secured to the sole structure and forms a void on the interior of the footwear for receiving a foot in a comfortable and secure manner.
  • the upper member may secure the foot with respect to the sole member.
  • the upper may extend around the ankle, over the instep and toe areas of the foot.
  • the upper may also extend along the medial and lateral sides of the foot as well as the heel of the foot.
  • the upper may be configured to protect the foot and provide ventilation, thereby cooling the foot. Further, the upper may include additional material to provide extra support in certain areas.
  • the sole structure is secured to a lower area of the upper, thereby positioned between the upper and the ground.
  • the sole structure may include a midsole and an outsole.
  • the midsole often includes a polymer foam material that attenuates ground reaction forces to lessen stresses upon the foot and leg during walking, running, and other ambulatory activities. Additionally, the midsole may include fluid-filled chamber, plates, moderators, or other elements that further attenuate forces, enhance stability, or influence the motions of the foot.
  • the outsole is secured to a lower surface of the midsole and provides a ground-engaging portion of the sole structure formed from a durable and wear-resistant material, such as rubber.
  • the sole structure may also include a sockliner positioned within the void and proximal a lower surface of the foot to enhance footwear comfort.
  • the upper may have multiple layers that each includes a variety of joined material elements.
  • the material elements may be selected to impart stretch-resistance, wear resistance, flexibility, air-permeability, compressibility, comfort, and moisture-wicking to different areas of the upper.
  • material elements are often cut to desired shapes and then joined together, usually with stitching or adhesive bonding.
  • the material elements are often joined in layered configuration to impart multiple properties to the same areas.
  • waste material from cutting and stitching processes also accumulates to a greater degree as the number and type of material elements incorporated into the upper increases.
  • uppers with a greater number of material elements may be more difficult to recycle than uppers formed from fewer types and number of material elements.
  • multiple pieces that are stitched together may cause a greater concentration of forces in certain areas.
  • the stitch junctions may transfer stress at an uneven rate relative to other parts of the article of footwear which may cause failure or discomfort. Additional material and stitch joints may lead to discomfort when worn.

  • Knitting direction refers to the orientation of interlooped yarns or strands forming a course or row of loops that are being joined to successive courses through a knitting process.
  • the knitting direction may be generally defined relative to the direction of the knit material being formed during the knitting process.

  • a “technical course” is used to refer to a row of needle loops produced by adjacent needles during the same knitting cycle. Each technical course refers to a pass of yarn along the knitting direction that interacts with at least one needle.

Therefore, the height or length of a knitted component that incorporates the first technical course may not increase by the addition of the second technical course.
