More specifically, in one embodiment, third zones 218, 232 can be formed using a half-gauge knit to provide a ribbed appearance, and third zones 218, 232 can be formed at least partially using one or more elastic yarns, such as spandex. Second zones 216, 230 can be formed using a full-gauge knit and can be formed using one or more elastic yarns, such as spandex.
  • second zones 216, 230 can have a mesh-type of appearance for increased breathability.
  • first zones 214, 228 can be formed using a full-gauge knit and can include yarns made from thermoplastic polymeric material. These yarns can be less elastic than yarns included in second and third zones 216, 230, 218, 232, and these yarns can partially melt and fuse to impart additional stiffness to the respective zones 214, 228 after heat is applied to upper 120. It will be appreciated that these thermoplastic yarns can be absent from second and third zones 216, 230, 218, 232. It will also be appreciated that the yarns of each zone 214, 216, 218, 228, 230, 232 can be incorporated and controlled through known intarsia knitting processes.
  • zones 214, 216, 218, 228, 230, 232 can be formed and incorporated according to the teachings in commonly-owned U.S. Patent Application Serial No. 13/691,316 to Podhajny, et al. , entitled "Article of Footwear Incorporating a Knitted Component,” filed November 30, 2012.
  • the knitted component 130 of upper 120 can provide weight savings for the article of footwear 100.
  • the knitted component 130 can provide different physical characteristics at different zones 214, 216, 218, 228, 230, 232 such that upper 120 can be comfortable, can provide localized support to the wearer's foot, and can be easy to put on and remove.
  • the knitting processes used to produce knitted component 130 can reduce waste, can reduce manufacturing time, and/or can provide other manufacturing advantages.
  • knitted component 130 can be formed from a plurality of subcomponents, namely, forward knitted component 150 and heel knitted component 152. As such, properties of knitted component 130 can be highly controlled during manufacture. For example, it will be appreciated that the heel region 103 of upper 120 can be important for providing support to the wearer's heel without sliding or rubbing uncomfortably on the wearer's skin. Thus, heel knitted component 152 can include relatively stiff first zone 228 for providing suitable support. Heel knitted component 152 can also include the more elastic second zone 230, which can be substantially centered on heel knitted component 152, such that the second zone 230 can stretch and conform comfortably against the wearer's heel.
  • the second zone 230 can also stretch and conform as the wearer's heel flexes during walking, running, and otherwise moves.
  • the heel knitted component 152 can provide an important balance of stiff support and flexure such that a separate heel counter may not be necessary in the article of footwear 100.
  • portions of upper 120 can be tailored and tuned for particular uses, for particular wearers, or for other purposes. For example, if the heel region 103 of upper 120 is to have a different desired physical property, for example to be made stiffer, then forward knitted component 150 could be joined to a different heel knitted component provided with a smaller second zone than second zone 230. Alternatively, if heel region 103 is to be made more flexible, then forward knitted component 150 could be joined to another different heel knitted component provided with a larger second zone than second zone 230.
  • knitted components 150, 152 can be formed to have one-piece unitary knit construction.
  • knitted components 150, 152 can be knit on flat knitting machines.
  • heel knitted component 152 can be knit such that upper peripheral edge 220 is formed first, and additional courses can be added until lower peripheral edge 222 is formed.
  • upper peripheral edge 220 can have a neat and finished appearance, and raw lower peripheral edge 222 can be eventually covered and bound by sole structure 110.
  • forward knitted component 150 can be formed such that second peripheral edge 209 is formed first, and courses can be added until first peripheral edge 208 is formed.
  • heel knitted component 152 can include an indicia 254, such as an "X" shown in FIG. 8 , which differentiates between an interior surface 250 of heel knitted component 152 and an exterior surface 252 of heel knitted component 152. It is noted that exterior surface 252 of heel knitted component 152, shown in FIG. 7 , does not include indicia 254. Thus, even if heel knitted component 152 is substantially symmetric, the manufacturer can differentiate between interior and exterior surfaces 250, 252 to assist with orienting heel knitted component 152 for attachment to forward knitted component 150.
  • interior surface 250 can partially define void 117 of upper 120, and exterior surface 252 can face outwardly.
  • exterior surface 252 can include indicia 254 instead of interior surface 250.
  • indicia 254 can be formed by yarns or strands included in the unitary knit construction of heel knitted component 152, or indicia 254 can be marked separately from unitary knit construction of heel knitted component 152.
  • indicia 254 can be located in any suitable location of heel knitted component 152. For example, as shown in FIG. 8 , indicia 254 can be substantially centered on heel knitted component 15 and may be adjacent to lower peripheral edge 222.
  • heel knitted component 352 can be substantially similar to the embodiments discussed above.
  • heel knitted component 352 can include a first zone 328, a second zone 330, and a third zone 332 similar to the embodiments discussed above.
  • heel knitted component 352 can define an internal boundary 361 demarcating third zone 332 from first zone 328 and second zone 330 that differs from the embodiments of FIG. 7 .
  • internal boundary 161 is located approximately a uniform distance from upper peripheral edge 220 in the embodiments of FIGS.
  • curvature of boundary 361 can be inverted relative to upper peripheral edge 320 such that portions of internal boundary 361 may be spaced apart from upper peripheral edge 320 by varying distances. For example, portions of internal boundary 361 disposed closer to second zone 330 may be spaced apart from upper peripheral edge 320 by a larger distance than other portions. Thus, the width of third zone 332 between upper peripheral edge 320 and internal boundary 361 can vary across third zone 332 in the plan view of FIG. 9 . This can allow heel knitted component 352 to conform closely to the wearer's heel for added comfort and support.
  • footwear 100 can provide several advantages. Footwear 100 can be comfortable to wear. Footwear 100 can provide support to the wearer's foot. Footwear 100 can also flex with the wearer's foot and can flexibly conform to the wearer's foot. Physical properties can vary across different regions of footwear 100 to further enhance performance.
  • Various knit structures may be incorporated into forward knitted component 150, heel knitted component 152, or other knitted components to impart a contoured (e.g., rounded, non-planar, or otherwise three-dimensional) configuration.
  • a gore may provide advantages of enhancing the comfort of footwear 100 and increasing the overall manufacturing efficiency of footwear 100.
  • Heel knitted component 400 has an upper peripheral edge 401 , a lower peripheral edge 402, a first side edge 403 that extends between upper peripheral edge 401 and lower peripheral edge 402, and a second side edge 404 that extends between upper peripheral edge 401 and lower peripheral edge 402.
  • Heel knitted component 400 defines an exterior surface 405 and an opposite interior surface 406.
  • the knit structure of heel knitted component 400 incorporates a gore region 410, which includes a gore that imparts a contoured configuration, as depicted in FIGS. 11A and 11B .
  • Gore region 410 is formed of unitary knit construction with a remainder of heel knitted component 400.
  • gore region 410 has a generally triangular shape that is centrally-located in heel knitted component 400 and extends through a majority (i.e., at least 50 percent) of a distance between peripheral edges 401 and 402, but may be smaller or larger in further configurations of heel knitted component 400.
  • the portion of heel knitted component 400 that includes gore region 410 corresponds with the location of the heel and achilles tendon of the wearer.
  • Gore region 410 provides a rounded aspect to heel knitted component 400, which may enhance the comfort of footwear 100 and increase the overall manufacturing efficiency of footwear 100.
  • Gore region 410 is at least partially located in a central area 407 of heel knitted component 400, which is centrally-located or spaced inwards from edges 401-404 and includes a center of heel knitted component 400.
  • Gore region 410 is depicted as having a generally triangular shape that arises from knitting a series of courses of decreasing length, and then knitting a series of courses of increasing length to insert a gore into heel knitted component 400. Referring to FIG.
  • a pair of courses 411 and 416 in gore region 410 have a relatively long length
  • a pair of courses 412 and 415 in gore region 410 have a lesser length than courses 411 and 416
  • a pair of courses 413 and 414 in gore region 410 have a lesser length than each of courses 411, 412, 415, 416.
  • the generally triangular shape of gore region 410 is formed by knitting courses of varying length in central area 407.
  • courses 411-416 are selected for purposes of example and gore region 410 may have numerous other courses, some of which are located between or otherwise separate courses 411-416. Additional details regarding the process for forming gore region 410 will be discussed in greater detail below.
  • gore region 410 provides one example that is suitable for footwear 100.
  • gore region 410 may have a variety of other shapes, including diamond, square, rectangular, elliptical, round, or irregular, depending upon the specific knitting method utilized to form gore region 410.
  • the size or location of gore region 410 may vary considerably to provide specific features (e.g., three-dimensional regions) to heel knitted component 400 or other areas of heel knitted component 400.
  • the orientation of gore region 410 may also vary.
  • a structure that is similar to gore region 410 may also be incorporated into forward knitted component 150 to impart a three-dimensional region.
  • FIGS. 12 and 13 Another configuration of heel knitted component 400 is depicted in FIGS. 12 and 13 as including a plurality of peripheral gore regions 420 that are distributed along or adjacent to lower peripheral edge 402 and on opposite sides of gore region 410. That is, a first portion of peripheral gore regions 420 are located on one side of the gore region 410, and a second portion of peripheral gore regions 420 are located on an opposite side of gore region 410. Peripheral gore regions 420 form a series of gores along a common edge (i.e., lower peripheral edge 402) of heel knitted component 400.
  • peripheral gore regions 420 are relatively small and may extend through less than one-third of the distance between peripheral edges 401 and 402, but may also extend through a lesser distance, including less than 20 percent, 15 percent, or 10 percent of the distance between peripheral edges 401 and 402.
  • gore region 410 may be at least two times, at least three times, or more than four times the area of each of peripheral gore regions 420.
  • An advantage of incorporating peripheral gore regions 420 into heel knitted component 400 relates to the rounded, non-planar, or otherwise three-dimensional configuration. More particularly, peripheral gore regions 420 may impart greater curvature to heel knitted component 400 than gore region 410 alone, as depicted through a comparison of FIGS.
  • peripheral gore regions 420 may be formed by knitting a series of courses of decreasing length, and then knitting a series of courses of increasing length to insert gores into heel knitted component 400.
  • a vertical axis V and horizontal axis H are superimposed over heel knitted component 400 in Figures 11A and 13 .
  • An angle 431 represents the deflection of heel knitted component 400 from vertical axis V.
  • an angle 432 represents the deflection of heel knitted component 400 from horizontal axis H.
  • angle 431 would be substantially zero in each of Figures 11A and 13 .
  • gore region 410 imparts contouring or curvature
  • heel knitted component 400 deflects away from vertical axis V and angle 431 is greater than zero.
  • angle 432 would be substantially similar in Figures 11A and 13 .
  • peripheral gore regions 420 imparts contouring or curvature, however, angle 432 is less in Figure 13 than in Figure 11A . That is, the curvature in heel knitted component 400 due to peripheral gore regions 420 causes portions of heel knitted component 400 that are adjacent to lower peripheral edge 402 to approach horizontal axis H.
  • Gore regions 410 and peripheral gore regions 420 each assist in imparting the contoured configuration to heel knitted component 400.
  • gore region 410 extends through a majority of a distance between peripheral edges 401 and 402
  • gore region 410 may be primarily responsible for imparting the overall rounded shape to heel knitted component 410, as depicted in FIGS. 11A and 11B .
  • peripheral gore regions 420 are located along lower peripheral edge 402
  • peripheral gore regions 420 may be primarily responsible for imparting a more rounded shape to the area of heel knitted component 410 that is adjacent to lower peripheral edge 402. Accordingly, gore region 410 and peripheral gore regions 420 operate cooperatively to form the rounded, non-planar, or otherwise three-dimensional configuration to specific areas of heel knitted component 400.
  • Peripheral gore regions 420 effectively curve or contour the portion of heel knitted component 400 that is adjacent to lower peripheral edge 402 to facilitate attaching heel knitted component 400 to one or both of forward knitted component and an upper surface or other portions of sole structure 110.
  • the contoured configuration in heel knitted component 400 forms a lip that is approximately parallel to the upper surface of sole structure 110 and may be used in place of strobel 125 to facilitate attachment of heel knitted component 400 to sole structure 110.
  • lower areas of forward knitted component 150 may include gore regions that are similar to peripheral gore regions 420 to continue to extend the lip around the periphery of upper 120 and facilitate attachment of upper 120 to sole structure 110. In some cases, this structure may be used together with strobel 125 or another strobel sock, or this structure may replace the use of a strobel 125.
  • heel knitted component 400 A further configuration of heel knitted component 400 is depicted in FIG. 14A , wherein gore region 410 extends inward from upper peripheral edge 401 and into an area corresponding with central area 407.
  • heel knitted component 400 has the general shape of heel knitted component 152 and incorporates gore region 410 into this shape.
  • FIG. 14C Another configuration of heel knitted component 400 is depicted in FIG. 14C as having a U-shaped configuration. Accordingly, various aspects relating to location of gore region 410 and the overall shape of heel knitted component 400 may vary considerably.
  • heel knitted component 400 is incorporated into footwear 100 in a similar manner. More particularly, first rear edge 210 of forward knitted component 150 can be coupled to first side edge 403 of heel knitted component 400, and second rear edge 212 of forward knitted component 150 can be coupled to second side edge 404 of heel knitted component 400. In addition, lower peripheral edge 402 may be secured to strobel 125 or an upper surface of sole structure 110.
  • first rear edge 210 and second rear edge 212 of forward knitted component 150 may be modified to join with side edges 403 and 404.
  • heel knitted component 400 and forward knitted component 150 are depicted as being secured to strobel 125, strobel 125 may be absent in some configurations of footwear 100.
  • gore region 410 When incorporated into footwear 100, gore region 410 extends upward in heel region 103 and through a majority of a distance between sole structure 110 and upper edge 132, which forms opening 121 (e.g., an ankle opening of upper 120). In this location, the convex configuration of interior surface 406 contacts and conforms with the heel and achilles tendon area of the wearer. Given that the rounded aspect of heel knitted component 400 may better conform with the contours of the wearer's foot than a planar knitted component, heel knitted component 400 may enhance the comfort of footwear 100.
  • peripheral gore regions 420 are located in heel region 103 and proximal to the interface between sole structure 110 and upper 120.
  • heel knitted component 400 adjacent to lower peripheral edge 404 conforms with the shape of an upper surface of midsole 111.
  • gore region 410 and peripheral gore regions 420 also shapes heel knitted component 400 during the knitting process, the number of shaping processes that occur prior to or during the lasting process that forms footwear 100 is decreased, thereby increasing the overall manufacturing efficiency of footwear 100.
  • Knitting machine 500 Although knitting may be performed by hand, the commercial manufacture of knitted components is generally performed by knitting machines.
  • An example of a knitting machine 500 that is suitable for producing any of knitted components 150, 152, and 400 is depicted in FIG. 17 .
  • Knitting machine 500 has a configuration of a V-bed flat knitting machine for purposes of example, but knitted components 150, 152, and 400 or aspects of knitted components 150, 152, and 400 may be produced on other types of knitting machines.
  • Knitting machine 500 includes two needle beds 501 that are angled with respect to each other, thereby forming a V-bed.
  • Each of needle beds 501 include a plurality of individual needles 502 that lay on a common plane. That is, needles 502 from one needle bed 501 lay on a first plane, and needles 502 from the other needle bed 501 lay on a second plane.
  • the first plane and the second plane of the two needle beds 501 are angled relative to each other and meet to form an intersection that extends along a majority of a width of knitting machine 500.
  • needles 502 each have a first position where they are retracted and a second position where they are extended. In the first position, needles 502 are spaced from the intersection where the first plane and the second plane meet. In the second position, however, needles 502 pass through the intersection where the first plane and the second plane meet.
  • a pair of rails 503 extend above and parallel to the intersection of needle beds 501 and provide attachment points for multiple feeders 504. Due to the action of a carriage 505, feeders 504 move along rails 503 and needle beds 501, thereby supplying yarns to needles 502.
  • a yarn 506 is provided to one of feeders 504 by a spool 507. More particularly, yarn 506 extends from spool 507 to various yarn guides 508, a yarn take-back spring 509, and a yarn tensioner 510 before entering feeder 504. Although not depicted, additional spools 507 may be utilized to provide yarns to other feeders 504.
  • heel knitted component 400 is formed by knitting machine 500, as depicted in FIG. 18A .
  • feeder 504 In forming this portion of heel knitted component 400, feeder 504 repeatedly moves along rail 503 and various courses are formed from at least yarn 506. More particularly, needles 502 pull sections of yarn 506 through loops of a prior course, thereby forming another course. It should be noted that although heel knitted component 400 is depicted as being formed from one yarn 506, additional yarns may be incorporated into heel knitted component 400 from further feeders 504.
  • Knitting machine 500 now begins the process of forming gore region 410, as depicted in FIG. 18B , by knitting a series of courses of decreasing length. More particularly, course 411 is formed, course 412 with a lesser length is formed after course 411, and then course 413 with an even lesser length is formed after each of courses 411 and 412. As courses 411, 412, and 413 are respectively formed with decreasing length, portions of previously-formed courses may be held on needles 502.
  • knitting machine 500 forms a remainder of gore region 410 by knitting a series of courses of increasing length. More particularly, course 414 is formed, course 415 with a greater length is formed after course 414, and then course 416 with an even greater length is formed after each of courses 414 and 415. As courses 414, 415, and 416 are respectively formed with increasing length, portions of previously-formed courses that were held on needles 502 are now joined with courses 414-416.
  • knitting machine 500 forms gore region 410 by knitting a first series of courses of decreasing length (e.g., courses 411-413), and then knitting a second series of courses of increasing length (e.g., courses 414-416) to insert a gore into heel knitted component 400, thereby forming gore region 410.
