Definitions

  • Embodiments of the present invention relate generally to articles of footwear; and more specifically to articles of footwear with dispensed components.
  • Articles of footwear are used to protect and cushion the wearer's feet. Because articles of footwear may be worn for an extended period of time, consumers desire articles of footwear that will fit properly to secure the article of footwear to the wearer's foot in a comfortable manner. It is desirable to achieve improved fit for articles of footwear in an efficient manner.
  • an article of footwear includes a sole, an upper, and a dispensed component.
  • the upper is coupled to the sole and includes an instep.

In some embodiments, the dispensed component extends over the instep from a medial featherline of the article of footwear to a lateral featherline of the article of footwear. In some embodiments, the dispensed component is not bonded to the upper between the medial featherline and the lateral featherline. In some embodiments, the dispensed component is not bonded to the instep. In some embodiments, the dispensed component is partially bonded to the upper (e.g., bonded between the medial featherline and the instep and between the lateral featherline and the instep, but not bonded across the instep). In some embodiments, the dispensed component is bonded to a medial featherline of the article of footwear and a lateral featherline of the article of footwear.

  • Embodiments of the present invention provide articles of footwear having one or more dispensed components created by an automated dispensing process. It is understood that while the term “dispensed” is generally used herein to refer to certain materials, these materials may also be “extruded.” Thus, the term “dispensed component” includes components that are dispensed and components that are extruded. These dispensed components may be dispensed from a mechanical device. In some embodiments, the dispensed components are 3-D printed. In some embodiments, the dispensed components are not 3-D printed.
  • an upper and/or a sole of the article of footwear may have one or more dispensed components.
  • an upper and/or a sole, or portions thereof can be formed from one or more dispensed components.

  • the dispensed component can be made of a composite material.
  • the cross-section of the dispensed component can be substantially circular, oval, rectangular, triangular, square, or any other suitable shape or design (e.g., star-shaped).
  • the cross-section of the dispensed component can be relatively flat (i.e., low profile).
  • the cross-section of the dispensed component may be adjusted dynamically and may vary throughout the automated dispensing process.
  • the dispensed component can be dispensed directly onto the article of footwear, such as directly onto the sole (e.g., insole, midsole, and/or outsole) or the upper.
  • the dispensed component can be dispensed directly onto a formed upper on a last (e.g., a flat knit upper, a circular knit upper, a formed three-dimensional knit, a sock, a fully-finished traditionally-lasted upper, etc.).
  • the upper may be made of a textile fabric, leather, synthetic, or film product.
  • the dispensing or extruding is done automatically (i.e., robotically).
  • a scanner may scan the upper and then robotically dispense the dispensed component onto the upper based on the scan.
  • the dispensed component may bond (e.g., by thermal fusion, chemical adhesion, or mechanical locking) to a portion of the article of footwear. In some embodiments, a portion of the dispensed component may bond to the article of footwear, while another portion of the dispensed component does not bond to the article of footwear.
  • the dispensed component may form an upper support element for the article of footwear.
  • the dispensed component may form a saddle.
  • the saddle extends over the instep of the article of footwear.
  • the saddle is not bonded to the article of footwear over the instep.
  • the saddle is bonded to the article of footwear at the medial featherline and the lateral featherline. The saddle may help secure the article of footwear to the wearer's foot.
  • the dispensed component that forms the saddle provides for some stretch, which may facilitate a more comfortable fit around the wearer's foot.
  • the dispensed component may form a portion of the sole of the article of footwear. In some embodiments, the dispensed component may form an outsole (i.e., a ground-contacting surface) of the article of footwear.
  • the sole comprises a foam midsole.
  • a substrate is disposed underneath the foam midsole. The substrate may be bonded to the foam midsole with an adhesive, such as a hot melt film, or traditionally cemented by way of solvent-based or water-based urethane adhesive. In some embodiments, the substrate provides a suitable surface for bonding with the dispensed component. In some embodiments, the dispensed component is dispensed onto the substrate, for example, in an undulating pattern, to form the outsole. Forming the sole with a dispensed component may provide flexibility and speed in development and manufacturing of the sole.
