  • the fit of the upper may be adjusted to provide the specific degree of tension or tightness the wearer may prefer.
  • Braided uppers are characterized by close containment over the wearer's foot.
  • the braided fabric may wrap all the way around the footwear, as shown in the figures. Such a structure has tensional integrity or "tensegrity," since the wearer's foot is in compression, while the braided strands are in tension around the wearer's foot.
  • Some examples may include braided uppers that extend beneath the foot, thereby providing 360 degree coverage at some regions of the foot. However, other examples need not include uppers that extend beneath the foot. In other examples, a braided upper could have a lower periphery joined with a sole structure and/or sock liner.
  • FIG. 2 illustrates an exploded isometric view of an article 100, including upper 102 which is comprised of a braided structure.
  • upper 102 is seen to have an opening 120 that may receive a foot.
  • upper 102 has a fastening region 124.
  • Fastening region 124 may further include a fastening gap 125 that separates a lateral fastening edge 126 from a medial fastening edge 127 (see FIG. 2 ).
  • Fastening region 124 may be further associated with that a fastening member 160.
  • fastening member 160 may be a lace.

  • second overlay portion 152 may help reinforce opening 120, so that the braided structure in the vicinity of opening 120 may not be overly stretched. Such reinforcement may be especially useful at opening 120, since opening 120 may undergo a great deal of pulling and other stress as a user inserts and/or removes his or her foot.
  • third overlay portion 154 may include a first section 171 that extends along lateral side 16 and a second section 172 that extends along medial side 18 of upper 102. Additionally, a third section 173 of third overlay portion 154 may extend beneath (e.g., on a lower side of) upper 102 at heel portion 14. In some examples, third section 173 joins first section 171 and second section 172 so that third overlay portion 154 wraps continuously around the sides and bottom of upper 102.
  • first section 171 of third overlay portion 154 extends from, and is continuously formed with, first section 181 of first overlay portion 150. Additionally, in some examples, second section 172 of third overlay portion 154 extends from, and is continuously formed with, second section 182 of first overlay portion 150. Because third overlay portion 154 may act to reduce stretching along its length, this configuration may help increase support under the heel by resisting stretching of the upper between first overlay portion 150 (at the top of the foot) and the lower side 199 (see FIG. 8 ) of heel portion 14.
  • FIG. 3 illustrates an enlarged view of a portion of article 100 where some strands may be bonded to a second overlay portion 152.
  • some strands 304 may be disposed against inner surface 302 second overlay portion 152.
  • strands 304 may form part of a closed woven edge 305 of upper 102 that lacks any loose or free ends of strands.
  • strands 304 may be bonded to second overlay portion 152 to reinforce the continuously woven section of the braided structure.
  • some strands 470 may be configured with loose or free ends 472.
  • open ends 472 may be secured to overlay portion 452 in order to keep strands 470 in place and help prevent strands 470 from loosening or unraveling.
  • an overlay portion may be used to retain the loose or free ends associated with the edge of a braided structure. Such an arrangement may provide a means of finishing cut edges of the braided structure, or any edges that include loose or free ends that might unravel.
  • the arrangement described here provides an overlay portion that may act to reinforce the edge of the braided structure at opening 120. This may help reduce stretching of upper 102 at opening 120, in order to preserve the structural integrity of upper 102.
  • second overlay portion 152 may help secure any loose or open ends of the braided structure to prevent fraying of the ends and/or unraveling of the braided structure.
  • exemplary materials used for bonding can include any known adhesives, melts, resins or other bonding agents.
  • FIG. 5 illustrates an isometric view of article 100, including an enlarged schematic cross-sectional view of a portion of first overlay portion 150 and fastening member 160.
  • first overlay portion 150 includes a plurality of eyelets 400.
  • plurality of eyelets 400 including eyelet 402 shown in the enlarged cross-section, are openings in first overlay portion 150 that are configured to receive portions of fastening member 160.
  • the preferred arrangement is configured so that strands of upper 102 are indirectly secured to fastening member 160 via eyelets in first overlay portion 150.
  • strands 410 are seen to be secured directly to first overlay portion 150, while fastening member 160 is secured through plurality of eyelets 400 in first overlay portion 150.
  • This configuration may distribute forces imparted by fastening member 160 more evenly across the braided structure of upper 102. This may prevent fastening member 160 from tugging too much on a particular strand, for example, thereby facilitating better comfort and fit of article 100 on a foot.
  • FIGS. 6 and 7 illustrate two possible configurations for strands in the vicinity of eyelets on an overlay portion.
  • one or more strands may extend around an eyelet, thereby acting to reinforce the eyelet.
  • first strand 512 and second strand 514 wrap around first eyelet 502 and second eyelet 504, respectively. This may have the effect of reinforcing first eyelet 502 and second eyelet 504, as well as providing a more direct transfer of tension between fastening member 160 and the braided strands of upper 102.
  • first eyelet 502 and second eyelet 504 are not surrounded by any strands of the upper.
  • strands 610 are bonded to first overlay portion 150 without encircling first eyelet 502 and second eyelet 504.

  • third overlay component 156 is seen to wrap underneath a bottom side 199 of upper 102 at heel portion 14. In some cases, this configuration allows third overlay portion 156 to cradle the heel of the foot. Thus, this arrangement may provide further support for the heel of the foot when article 100 is worn by reducing stretching through heel portion 14.
  • distinct overlay components may be used.
  • distinct overlay components may be configured to intersect or overlap at predetermined portions of an upper.

  • Second overlay component 812 is associated with forward toe portion 868 of upper 802. In some examples, second overlay component 812 may help improve stretch resistance at forward toe portion 868. Additionally, in some examples, second overlay component 812 may provide a covering for forward toe portion 868. In particular, the presence of second overlay component 812 may help prevent debris from entering upper 802 through forward toe portion 868.

  • third overlay component 814 is comprised of a first band 817 and a second band 819, which are integrally joined at top intersection region 815. This arrangement may therefore provide targeted stretch resistance at forefoot portion 811 that enhances support of the foot during activities where forefoot portion 811 may be firmly planted on the ground.
  • Fourth overlay component 816 may be associated with heel portion 813 of upper 802.
  • fourth overlay component 816 may provide a heel-counter like overlay portion 825, as well as a strap-like overlay portion 827.
  • overlay portion 825 and overlay portion 827 may help limit stretching at heel portion 813 and may therefore enhance support of the heel within upper 802.

  • one or more members of the intermediate layer may be rigidly held into a position by the overlay system.
  • the ankle pad 2602 is rigidly attached to the overlay system 2140.
  • the heel pad 2604 is rigidly attached to the overlay system 2140.
  • one or more members of the intermediate layer 2601 may directly contact the overlay system 2140.
  • the ankle pad 2602 directly contacts the second overlay portion 2152 and/or the fifth overlay portion 2158.
  • the heel pad 2604 directly contacts the second overlay portion 2152 and/or the fifth overlay portion 2158.
  • overlay portions may be applied at selective locations of an upper (and not applied in other locations) to enhance stretch resistance, strength, rigidity and/or other material properties at the selective locations.
  • overlay system 2140 includes overlay portions that are selectively placed on the edges of first braided structure 2006 and second braided structure 2008, but not in some portions interior to these edges (e.g., a toe portion, some of the lateral and medial sides and some of the bottom side of upper 2004). This selective placement of overlay portions allows for improved stretch resistance and strength at the edges, but retains improved flexibility, relatively low rigidity, and breathability in portions not covered by overlay portions.
  • FIGS. 31 and 32 illustrate an improved functionality of upper 2004 due to the use of selective placement of overlay portions in some areas, but not others, of upper 2004.
  • ankle pad 2602 is held between first braided structure 2006 and second braided structure 2008.
  • second overlay portion 2152 and fifth overlay portion 2158 are bonded to first braided structure 2006 and second braided structure 2008 (and to one another) to help hold ankle pad 2602 in a predetermined region of upper 2004.
  • second overlay portion 2152 and fifth overlay portion 2158 keep first braided structure 2006 and second braided structure 2008 attached around ankle pad 2602 such that ankle pad 2602 cannot translate outside of the boundary defined by second overlay portion 2152 and fifth overlay portion 2158.
  • the upper 2004 may allow for an improved impact absorption by distributing an impact force onto an intermediate layer 2601.
  • FIG. 31 illustrates the ankle pad 2602 positioned to protect the ankle 2706.
  • the first braided structure 2006 and the second braided structure 2008 support the ankle pad 2602.
  • a force 2708 contacting the second braided structure 2008 deforms the second braided structure 2008 to distribute force 2708.
  • Such a deformation may help the intermediate layer 2601 (e.g., ankle pad 2602) absorb the impact by distributing the impact force 2708 into the intermediate layer 2601.
  • Second braided structure 2008 may be easily deformed due to its low rigidity and relative flexibility. This may be in contrast to regions of upper 2004 that include overlay portions, which may be specifically designed to limit flexibility and may generally increase rigidity of these regions to strengthen the connection between first braided structure 2006 and second braided structure 2008.
  • overlay portions may be specifically designed to limit flexibility and may generally increase rigidity of these regions to strengthen the connection between first braided structure 2006 and second braided structure 2008.
  • FIGS. 33 and 34 An alternative embodiment of a portion of an upper including an intermediate cushioning layer 2760 and a rigid layer 2710 is shown in FIGS. 33 and 34 .
  • rigid layer 2710 may generally have a uniform rigidity, stretch resistance and/or strength, as opposed to the selective material characteristics provided by the embodiment shown in FIGS. 31-32 .
  • a force 2708 applied to the rigid upper 2710 may be partially transmitted to intermediate cushioning layer 2760.
  • some of force 2708 may also be transmitted along regions 2711 of rigid upper 2710 that are peripheral of intermediate cushioning layer 2760. This may result in less efficient cushioning, as only some of force 2708 is absorbed by intermediate cushioning layer 2760, while the rest of force 2708 is transmitted to other locations of rigid upper 2710.
