DETAILED DESCRIPTION
FIGS. 1 through 5 illustrate an exemplary embodiment of article of footwear 100. For clarity, the following detailed description discusses an exemplary embodiment, in the form of a sports shoe, but it should be noted that the present invention could take the form of any article of footwear including, but not limited to: hiking boots, soccer shoes, football shoes, sneakers, rugby shoes, basketball shoes, baseball shoes as well as other kinds of shoes. As shown in FIGS. 1 through 5, article of footwear 100, also referred to simply as article 100, is intended to be used with a left foot; however, it should be understood that the following discussion may equally apply to a mirror image of article of footwear 100 that is intended for use with a right foot.
Referring to FIGS. 1 through 5, for purposes of reference, article 100 may include forefoot region 10, midfoot region 12 and heel region 14. Forefoot region 10 may be generally associated with the toes and joints connecting the metatarsals with the phalanges. Midfoot region 12 may be generally associated with the arch of a foot. Likewise, heel region 14 may be generally associated with the heel of a foot, including the calcaneus bone. In addition, article 100 may include medial side 16 and lateral side 18. In particular, medial side 16 and lateral side 18 may be opposing sides of article 100. Furthermore, both medial side 16 and lateral side 18 may extend through forefoot region 10, midfoot region 12 and heel region 14.
It will be understood that forefoot region 10, midfoot region 12 and heel region 14 are only intended for purposes of description and are not intended to demarcate precise regions of article 100, but rather, to describe relative positions. Likewise, medial side 16 and lateral side 18 are intended to represent generally two sides of an article, rather than precisely demarcating article 100 into two halves. In addition, forefoot region 10, midfoot region 12 and heel region 14, as well as medial side 16 and lateral side 18, can also be applied to individual components of an article, such as a sole structure and/or an upper.
For consistency and convenience, directional adjectives are employed throughout this detailed description corresponding to the illustrated embodiments. The term “longitudinal” as used throughout this detailed description and in the claims refers to a direction extending a length of an article. In some cases, the longitudinal direction may extend from a forefoot region to a heel region of the article. Also, the term “lateral” as used throughout this detailed description and in the claims refers to a direction extending a width of an article. In other words, the lateral direction may extend between a medial side and a lateral side of an article. Furthermore, the term “vertical” as used throughout this detailed description and in the claims refers to a direction generally perpendicular to a lateral and longitudinal direction. For example, in cases where an article is planted flat on a ground surface, the vertical direction may extend from the ground surface upward. It will be understood that each of these directional adjectives may be applied to individual components of an article, such as an upper and/or a sole structure.
Article 100 may include an upper 102 and sole structure 106. In some embodiments, sole structure 106 may be configured to provide traction for article 100. In addition to providing traction, sole structure 106 may attenuate ground reaction forces when compressed between the foot and the ground during walking, running or other ambulatory activities. The configuration of sole structure 106 may vary significantly in different embodiments to include a variety of conventional or non-conventional structures. In some cases, the configuration of sole structure 106 may be configured according to one or more types of ground surfaces on which sole structure 106 may be used. Examples of ground surfaces include, but are not limited to: natural turf, synthetic turf, dirt, as well as other surfaces.
Sole structure 106 is secured to upper 102 and extends between the foot and the ground when article 100 is worn. In different embodiments, sole structure 106 may include different components. For example, sole structure 106 may include an outsole, a midsole, and/or an insole. In some cases, one or more of these components may be optional. Sole structure 106 may be made from any suitable material, including a material that includes, but is not limited to, elastomers, siloxanes, natural rubber, other synthetic rubbers, aluminum, steel, natural leather, synthetic leather, or plastics.
In some embodiments, portions of sole structure 106 may include provisions for enhancing traction for purposes of better ball control during kicks. In one embodiment, sole structure 106 may include portions disposed along an outer periphery comprising a material that has a high coefficient of friction to provide better grip on a ball during kicks. In an exemplary embodiment, sole structure 106 may include a toe grip 130 disposed along an outer periphery of sole structure 106 at forefoot region 10. In various embodiments, toe grip 130 may comprise a roughened surface material for enhancing traction with a ball, including, but not limited to materials that include natural rubber, synthetic rubber, natural leather, synthetic leather, or plastics, as well as any other suitable material.
Article of footwear 100 may include upper 102. Generally, upper 102 may be any type of upper. In particular, upper 102 may have any design, shape, size and/or color. For example, in embodiments where article 100 is a soccer shoe, upper 102 could be a low top upper. In embodiments where article 100 is a basketball shoe, upper 102 could be a high top upper that is shaped to provide high support on an ankle. Generally, upper 102 may be made from any suitable material, including a material that includes, but is not limited to, nylon, natural leather, synthetic leather, natural rubber, or synthetic rubber. In some cases, upper 102 can be made of any suitable knitted, woven or non-woven material.
For purposes of clarity, only some portions of upper 102 are discussed in the exemplary embodiments. It should be understood that upper 102 may include other provisions that are known in the art for assisting in walking, running or other athletic maneuvers.
Typically, upper 102 may be configured to receive a foot of a wearer. In some embodiments, upper 102 includes entry hole or throat opening 104 configured to receive a foot of a wearer. With this arrangement, entry hole or throat opening 104 may allow a foot to be inserted into an interior of upper 102.
Article 100 may include lacing system 110. In some cases, lacing system 110 may include a medial lacing edge 112 and a lateral lacing edge 114 that are separated by lacing gap 116. In particular, lacing gap 116 may extend from throat opening 104 of upper 102 towards forefoot region 10. In addition, lacing gap 116 may be associated with one or more lacing holes that are disposed on medial lacing edge 112 and lateral lacing edge 114. Furthermore, lacing gap 116 may be further associated with a lace 118 that may be disposed through one or more lacing holes. With this arrangement, lace 118 may be used to tighten upper 102 around a foot.
In different embodiments, the shape of lacing gap 116 may vary. In some cases, lacing gap 116 may have a substantially straight shape. In other cases, lacing gap 116 may have a curved shape. In one embodiment, lacing gap 116 may be shaped to curve towards medial side 16 from throat opening 104. In other words, lacing gap 116 may be arranged in an asymmetric manner on upper 102.

In this embodiment, ball control portion 120 tapers gradually towards lateral front edge 400 from second distance L2. In this embodiment, ball control portion 120 may taper rapidly towards lateral rear edge 404 from second distance L2. In different embodiments, ball control portion 120 may taper more or less gradually from second distance L2 at lateral midsection edge 402 into forefoot region 10 and/or heel region 14.
In some embodiments, ball control portion 120 may be associated with one or more portions of article 100. In one embodiment ball control portion may be associated with one or more of medial side 16, lateral side 18, and/or underside 300 of article 100. FIG. 5 illustrates an exemplary embodiment of article of footwear 100 with ball control portion 120 associated with medial side 16 and underside 300. In this embodiment, ball control portion 120 may be disposed over a portion of medial side 16 adjacent to upper 102 and a portion of underside 300 disposed between forefoot outsole portion 302 and heel outsole portion 304. In this embodiment, ball control portion 120 may extend forward on article 100 to medial front edge 122 in forefoot region 10 of medial side 16 adjacent to sole structure 106. Similarly, ball control portion 120 may extend forward on article 100 to forefoot edge 310 in forefoot region 10 of underside 300 adjacent to forefoot outsole portion 302. Ball control portion 120 may extend rearward on article 100 to medial rear edge 126 of medial side 16 and to heel edge 312 on underside 300 in heel region 14 of article 100.
In some embodiments, portions of ball control portion 120 associated with each of medial side 16, lateral side 18, and/or underside 300 of article 100 may be substantially continuous between one or more portions. In other words, ball control portion 120 may include a substantially continuous lattice 202 disposed over article 100 extending from medial side 16 to underside 300 of article 100. In other embodiments, ball control portion 120 may include a substantially continuous lattice 202 extending between medial side 16, underside 300, and lateral side 18 of article 100. In some embodiments, ball control portion 120 may be substantially continuous between lateral side 18 and underside 300. In some cases, one or more portions of ball control portion 120 may not be substantially continuous with one or more other portions of ball control portion 120. For example, in one embodiment, lattice 202 may be substantially continuous between medial side 16 and underside 300, however, a separate lattice may form ball control portion 120 on lateral side 18 of article 100. In still other embodiments, ball control portion 120 associated with each of medial side 16, lateral side 18, and/or underside 300 of article 100 may be separate.
FIG. 6 illustrates an enlarged view of a portion of lattice 202 forming ball control portion 120. In this embodiment, lattice 202 includes plurality of protrusions 200. Plurality of protrusions 200 may include one or more individual protrusions, including a first protrusion 600. Plurality of protrusions 200 may be connected to one another by connecting members 204. Furthermore, plurality of protrusions 200 and connecting members 204 may be spaced apart by gaps 620. This arrangement may provide a web-like configuration for lattice 202. In other embodiments, however, lattice 202 may comprise a substantially solid layer without gaps 620.
In different embodiments, gaps 620 may have varying shapes including, but not limited to: rounded shapes (such as circular or oval shapes), polygonal shapes (such as triangular, rectangular, pentagonal, etc.), regular shapes, irregular shapes, or any other types of shapes. In some cases, gaps 620 may have substantially similar shapes to one another. In other cases, different gaps of gaps 620 may have substantially different shapes. Furthermore, in some cases, gaps 620 may have shapes that correspond to the shapes of plurality of protrusions 200. In other cases, however, gaps 620 may have different shapes from plurality of protrusions 200. In the current embodiment, gaps 620 may have substantially diamond shapes that correspond to the arrangement of plurality of protrusions 200. In other embodiments, however, gaps 620 may have any other shapes including any of the shapes discussed above.
In some embodiments, lattice 202 may be disposed on a substrate layer of article 100. In one embodiment, the substrate layer may be exposed in gaps 620 between portions of lattice 202. In an exemplary embodiment, the substrate layer may be constructed of a resilient foam material. In different embodiments, the substrate layer may be constructed from any materials, including materials discussed above for constructing article 100 and/or upper 102. In an exemplary embodiment, the substrate layer may be provided on portions of article 100 including ball control portion 120 so that lattice 202 may be disposed approximately flush with upper 102 and/or underside 300. In other embodiments, the substrate layer may include upper 102 and/or substantially the same materials as the materials used to construct upper 102. In different embodiments, the substrate layer may be provided on article 100 so that lattice 202 may be disposed above the surface of upper 102 and/or underside 300.
Using the arrangement discussed above, the structural properties of lattice 202 may be varied. For example, by varying the size, shape and number of gaps 620 in lattice 202, the rigidity of lattice 202 may be varied. In addition, by increasing the number of gaps, and thus decreasing the material comprising base lattice 202, the overall weight of lattice 202 may be reduced to help minimize additional weight on article 100.
In some embodiments, lattice 202 may include additional elements for the purposes of providing additional rigidity to portions of lattice 202. In some cases, additional elements may provide rigidity to one or more of the plurality of protrusions 200. In an exemplary embodiment, a supporting member 610 may provide additional rigidity to first protrusion 600. In some cases, supporting member 610 may provide support to first protrusion 600 along a direction that first protrusion 600 may be configured to bend. In this embodiment, supporting member 610 may be disposed behind one side of first protrusion 600 in gap 620. In other cases, supporting member 610 may be disposed behind one or more sides of first protrusion 600.
In an exemplary embodiment, supporting member 610 may be formed integrally with lattice 202. In one embodiment, supporting member 610 may be formed together with one or more of the plurality of protrusions 200, including first protrusion 600. In this embodiment, supporting member 610 is formed with the same material as first protrusion 600. In other embodiments, supporting member 610 may be formed separately from plurality of protrusions 200. In one embodiment, supporting member 610 may be formed integrally with one or more connecting members 204. In other embodiments, supporting member 610 may be formed separately from lattice 202, plurality of protrusions 200, and/or connecting members 204. Additionally, supporting member 610 may be constructed of the same or different materials as any of lattice 202, plurality of protrusions 200, and/or connecting members 204.
In some embodiments, supporting member 610 may have a generally spheroid shape. In other embodiments, supporting member 610 may have any shape configured to provide support, including, but not limited to: rounded shapes (such as circular or oval shapes), polygonal shapes (such as triangular, rectangular, pentagonal, etc.), regular shapes, irregular shapes, or any other types of shapes. In an exemplary embodiment, ball control portion 120 may include a plurality of supporting members substantially identical to supporting member 610. In other embodiments, ball control portion 120 may include one or more supporting members with different shapes. In some cases, the size and/or height of a supporting member may be configured to provide more or less rigidity to an individual protrusion. In other cases, multiple supporting members may be associated with an individual protrusion to provide additional support. In still other cases, one supporting member may be configured to provide support to more than one protrusion.
FIG. 7 illustrates an isolated view of first protrusion 600 for purposes of illustrating the geometry of plurality of protrusions 200. Referring to FIG. 7, for purposes of description, first protrusion 600 may be associated with major axis 781, minor axis 782 and normal axis 783 in the manner described above. In some cases, first protrusion 600 may include first major face 704 and second major face 705, which is disposed opposite of first major face 704. First major face 704 and second major face 705 may form sidewalls for first protrusion 600. In particular, include first major face 704 and second major face 705 are approximately planar surfaces that extend along major axis 781 and normal axis 783 of first protrusion 600. In other embodiments, however, include first major face 704 and second major face 705 may be substantially curved surfaces.
First protrusion 600 may also include a first side edge 706 and a second side edge 707 that extend along minor axis 782 between first major face 704 and second major face 705. In some cases, first side edge 706 and second side edge 707 may be approximately planar edges. In other cases, however, first side edge 706 and second side edge 707 may be approximately rounded edges. In addition, first protrusion 600 may include top surface 702 that extends along major axis 781 and minor axis 782 at an outward most end of first protrusion 600. In some cases, top surface 702 may be an approximately planar top surface that presents a flat end for first protrusion 600. In other cases, however, top surface 702 may be a rounded surface.
In different embodiments, the dimensions of first protrusion 600 may vary. In an exemplary embodiment, the length of first protrusion 600, which is associated with major axis 781, may be substantially larger than the width, which is associated with minor axis 782. Likewise, the height of first protrusion 600, which is associated with normal axis 783, may be substantially larger than the width. Still further, the length may be substantially larger than the height. With this arrangement for the dimensions of first protrusion 600, first major face 704 and second major face 705 may comprise a majority of the surface area of first protrusion 600.
Referring now to FIG. 8, in some embodiments, first protrusion 600 may be configured to bend. In some cases, first protrusion 600 may be configured to bend about an axis approximately parallel to major axis 781. In other words, first protrusion 600 may be configured to bend in a manner that disposes either first major face 704 or second major face 705 closer to the outer surface of upper 102. For example, in one direction of bending, first major face 704 may approximately confront supporting member 610. Furthermore, in this case, second major face 705 may be oriented to face outwardly and away from upper 102. In addition, in a second direction of bending, second major face 705 may approximately confront lattice 202. Furthermore, in this case, first major face 704 may be oriented to face outwardly and away from upper 102. With this arrangement, as first protrusion 600 bends, either first major face 704 or second major face 705 are exposed outwardly from upper 102. This arrangement may increase the surface area of first protrusion 600 that is exposed outwardly on upper 102, which can help increase grip on a ball during kicks, for example.
In some embodiments, supporting member 610 may provide additional rigidity to first protrusion 600 in one direction of bending. In an exemplary embodiment, first major face 704 may approximately confront supporting member 610 in one direction of bending. In this embodiment, supporting member 610 may provide support to first protrusion when bending in one direction. With this arrangement, supporting member 610 may provide additional rigidity to first protrusion 600 when bending in a direction of supporting member 610. In some embodiments, the size and/or height of supporting member 610 may be configured to allow a desired degree of bending of first protrusion 600. In this embodiment, supporting member 610 may be configured to allow first protrusion 600 to bend to a first angle 800. In other cases, ball control portion 120 may not include supporting member 610 and first major face 704 and second major face 705 of first protrusion 600 may bend substantially similar amounts in each respective direction.
It will be understood that the discussion above for first protrusion 600 may be applied to any protrusion of plurality of protrusions 200. In other words, the general geometry of each protrusion of plurality of protrusions 200 may be substantially similar to the geometry described for first protrusion 600. In addition, each protrusion of plurality of protrusions 200 may be provided with at least one major face that is configured to contact a ball. Furthermore, each protrusion may be configured to bend in a similar manner about a major axis of the protrusion so as to expose a major face outwardly on upper 102.
A ball control portion including protrusions may include provisions for improving contact with a ball during kicks. In some embodiments, ball control portion 120 may be selectively applied to portions of article 100 that impact a ball during various types of kicks. In one embodiment, ball control portion 120 including plurality of protrusions 200 may be selectively applied to a predetermined kicking region of article 100. The term “predetermined kicking region” as used throughout this detailed description and in the claims refers to a region of an article that is configured to impact a ball during a predetermined type of kick. For example, in a free kick situation in soccer, a player may want to put sidespin on the ball in order to curve the trajectory of the ball. This type of kick is often referred to as a “banana kick,” and is useful for kicking the ball at a target that is on the other side of an obstruction, such as an opposing player. In order to apply sidespin to the ball, the play may kick the ball off center using the medial side, or instep of the upper. Therefore, in some embodiments, ball control portion 120 may include plurality of protrusions 200 that are disposed on the instep of the upper to facilitate a kick in which sidespin is applied to the ball.
Referring to FIGS. 9 and 10, in the current embodiment, plurality of protrusions 200 may arranged on a predetermined kicking region of ball control portion 120. In some embodiments, the predetermined kicking region may be disposed on medial side 16 of upper 102. Furthermore, the predetermined kicking region may extend along ball control portion 120 from medial front edge 122 to medial rear edge 126 in midfoot region 12. In some embodiments, the predetermined kicking region of ball control portion 120 may correspond to an arch of a foot of a wearer. In the current embodiment, the predetermined kicking region may include the instep of upper 102 as well as adjacent areas to the instep. With this arrangement, plurality of protrusions 200 may be disposed on portions of article 100 that are most likely to contact a ball during a medial side kick.
Plurality of protrusions 200 of ball control portion 120 may be oriented in a manner that increases the contact area between plurality of protrusions 200 and a rounded surface such as a ball. In some embodiments, plurality of protrusions 200 may be arranged in a curved configuration that corresponds to the natural curvature of a ball surface, which is approximately spherical. In one embodiment, plurality of protrusions 200 may be arranged in an arc-like configuration. The term “arc” as used throughout this detailed description and in the claims refers to any segment of a curve. In some cases, an arc may be a segment of a circle. In other cases, however, an arc may be a segment of any other type of curve.
In one embodiment, plurality of protrusions 200 may be arranged in an arc-like configuration at midfoot region 12 of article 100. In some embodiments, one or more portions of ball control portion 120 may be configured to have a contour along the surface of article 100. In one embodiment, plurality of protrusions 200 may be arranged within lattice 202 of ball control portion 120 to have a contoured shape along the outer surface of article 100. In an exemplary embodiment, the contoured shape of ball control portion 120 in midfoot region 12 of medial side 16 may be configured to generally correspond to the contour of an arch of a foot of a wearer.
As shown in FIG. 9, the contour of ball control portion 120 at midfoot region 12 of medial side 16 in this embodiment may correspond to a generally concave contour associated with a first radius R1. In other embodiments, the contour may be generally convex. In some cases, first radius R1 may correspond to the approximate curvature of an arch of a foot of a wearer. In other cases, first radius may correspond to the natural curvature of a ball surface, which is approximately spherical. In some cases, first radius R1 may be a segment of a circle. In other cases, however, first radius R1 may be a segment of any other type of curve.
In some embodiments, the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may have a configuration that corresponds to the curvature of a generally spherical ball. For example, in one embodiment, the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may correspond to the curvature of a soccer ball. In particular, the shape and size of the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may be selected so that as a ball contacts the predetermined kicking region, plurality of protrusions 200 may be substantially tangent to an outer surface of the ball. It will be understood that in other embodiments, the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may correspond to the shapes of different shapes and/or sizes of balls. For example, in another embodiment, the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may have a size and shape that correspond to the curvature of a football that is used in American football. In still another embodiment, the arc-like configuration of plurality of protrusions 200 and/or contour of ball control portion 120 may have a size and shape that corresponds to the curvature of a ball that is used in rugby.
FIG. 10 illustrates an embodiment of a foot 1000 of an athlete kicking a ball 1002. In particular, as shown, the athlete is intending to kick ball 1002 in a manner that imparts sidespin to ball 1002 so that the trajectory of ball 1002 may be curved. Although the current embodiment illustrates a kick performed using a medial side of a left foot, in other embodiments the athlete may use the medial side of a right foot to perform a similar type of kick.
Ball control portion 120 on article 100 may contact an outer surface of ball 1002. More specifically, ball 1002 may contact plurality of protrusions 200 of ball control portion 120. Under the force of impact between ball control portion 120 and ball 1002, plurality of protrusions 200 may bend. In some embodiments, as the motion of foot 1000 is sideways as well as vertically upwards, plurality of protrusions 200 may bend or deflect downwards. In one embodiment, plurality of protrusions 200 may be bent towards an outer surface of article 100.
In an exemplary embodiment, for purposes of illustrating the bending of plurality of protrusions 200 when contacting ball 1002, plurality of protrusions 200 may include a first protrusion 1010, a second protrusion 1012, a third protrusion 1014, a fourth protrusion 1016, a fifth protrusion 1018, and a sixth protrusion 1020. In this embodiment, a number of protrusions disposed towards forefoot region 10 of article 100 may confront the surface of ball 1002. In the current embodiment, third protrusion 1014, fourth protrusion 1016, fifth protrusion 1018, and sixth protrusion 1020 may bend when contacting ball 1002. In this embodiment, ball 1002 has arrived at article 100 in a direction from forefoot region 10 and towards heel region 14. Accordingly, in this embodiment, ball 1002 has contacted third protrusion 1014, fourth protrusion 1016, fifth protrusion 1018, and sixth protrusion 1020, but has not contacted first protrusion 1010 and/or second protrusion 1012.
Additionally, in some embodiments, each protrusion may bend in correspondence to the amount of force received when contacting ball 1002. In some cases, the amount of force received when contacting ball 1002 may vary as a function of the speed and direction of ball 1002 when contacting article 100. In this embodiment, where ball 1002 has arrived in a direction from forefoot region 10 and towards heel region 14, sixth protrusion 1020 and/or fifth protrusion 1018 may bend to a greater degree than fourth protrusion 1016 and/or third protrusion 1014. In other cases, one or more protrusions on ball control portion 120 may be configured to bend more or less in different regions of ball control portion 120.
Furthermore, because of the flexibility of plurality of protrusions 200, third protrusion 1014, fourth protrusion 1016, fifth protrusion 1018, and sixth protrusion 1020 may conform to ball 1002 in a manner that maximizes the surface contact area between one or more major faces of each protrusion and the surface of ball 1002. In contrast to situations where a ball may only contact a small region of an upper, the current embodiment provides flexible protrusions that bend in a manner to create a greater surface contact area between article 100 and ball 1002.
In addition, as illustrated in FIG. 10, the contoured shape of ball control portion 120 in the current embodiment may correspond to the curvature of ball 1002. This arrangement may facilitate increased grip between ball control portion 120 and ball 1002, as an athlete continues the kicking motion. In particular, the vertical component of the kicking motion is applied to the surface of ball 1002 due to the enhanced grip provided by ball control portion 120. This arrangement acts to add rotation, or sidespin, to ball 1002 as ball 1002 is kicked forwards.
Because plurality of protrusions 200 are longer in one direction than they are the other, plurality of protrusions 200 may change characteristics depending on how the ball is kicked. The spin put on a ball by kicking at one angle may differ from the spin put on a ball by kicking at another angle. Further, because plurality of protrusions 200 provide a flexible and adaptable surface, plurality of protrusions 200 may adapt to accommodate a particular user and particular kinds of kicks.
Although the current embodiment discusses the use of plurality of protrusions 200 for applying side spin to a ball during a particular type of kick, in other embodiments plurality of protrusions 200 may be used to apply other types of spin to a ball as well. In particular, the orientation and location of a plurality of protrusions may be varied to facilitate applying different types of spin to a ball for different types of kicks. For example, in other cases, a plurality of protrusions may be used to apply sidespin, topspin, backspin as well as other types of spin to a ball. In addition, in other embodiments, a plurality of protrusions may be used to enhance grip between an upper and a ball for other purposes as well. For example, in another embodiment, a plurality of protrusions may help enhance grip between a ball and an upper for purposes of receiving or making a pass. In still another example, a plurality of protrusions may be used to enhance grip between a ball and an upper for purposes of performing special maneuvers such as bicycle kicks or heel kicks.
The current embodiment illustrates a ball control portion disposed on a medial side of an article, however, in other embodiments a ball control portion comprising a plurality of protrusions could be associated with any other region of an article, including any other predetermined kicking region that is associated with a predetermined type of kick. For example, in one embodiment, a ball control portion could be disposed on a lateral side of an upper for kicking a ball with a lateral side of the upper. In another embodiment, a ball control portion could be disposed on a heel portion of the upper for performing heel kicks or rainbow kicks.
In some embodiments, ball control portion 120 may be disposed on underside 300 and/or lateral side 18 of article 100. In this embodiment, plurality of protrusions 200 may apply different types of spin and/or other characteristics when contacting ball 1002. In one embodiment, ball control portion 120 disposed on underside 300 of article 100 may include plurality of protrusions 200 arranged to trap ball 1002 against a ground surface. In other embodiments, ball control portion 120 disposed on lateral side 18 of article 100 may include plurality of protrusions 200 arranged to apply different types of spin to ball 1002 when hit with the lateral side of a foot.
FIG. 11 illustrates an embodiment of a foot 1000 of an athlete trapping a ball 1002. In particular, as shown, the athlete is applying weight from foot 1000 disposed in article 100 to ball 1002, trapping ball 1002 between ball control portion 120 and a ground surface. Although the current embodiment illustrates a trap performed using an underside of an article associated with a left foot, in other embodiments the athlete may use the underside of a right foot to perform a similar type of maneuver.
In some embodiments, ball control portion 120 disposed on underside 300 of article 100 may contact an outer surface of ball 1002. More specifically, ball 1002 may contact a plurality of protrusions of ball control portion 120. By applying weight from a foot of a wearer to article 100, ball 1002 may be trapped between ball control portion 120 and the ground surface. In an exemplary embodiment, for purposes of illustrating the bending of plurality of protrusions 200 when trapping ball 1002, plurality of protrusions 200 may include a first protrusion 1030, a second protrusion 1032, a third protrusion 1034, a fourth protrusion 1036, and a fifth protrusion 1038. In this embodiment, a number of protrusions disposed on ball control portion 120 on underside 300 of article 100 may confront the surface of ball 1002. In the current embodiment, third protrusion 1034, fourth protrusion 1036, and fifth protrusion 1038 may bend when trapping ball 1002. In this embodiment, ball 1002 has arrived at article 100 in a direction from forefoot region 10 and towards heel region 14. Accordingly, in this embodiment, ball 1002 may be trapped by third protrusion 1034, fourth protrusion 1036, and fifth protrusion 1038, but has not contacted first protrusion 1030 and/or second protrusion 1032.
Furthermore, because of the flexibility of plurality of protrusions 200, third protrusion 1034, fourth protrusion 1036, and fifth protrusion 1038 may conform to ball 1002 in a manner that maximizes the surface contact area between one or more major faces of each protrusion and the surface of ball 1002. With this arrangement, ball 1002 may be trapped between article 100 and the ground surface. In contrast to situations where a ball may only contact the underside of an article, the current embodiment provides flexible protrusions that bend in a manner to create a greater surface contact area between article 100 and ball 1002 for trapping ball 1002 to the ground surface.
In the exemplary embodiment illustrated in FIG. 11, plurality of protrusions 200 of ball control portion 120 on underside 300 of article 100 are shown bending in a direction towards heel region 14 to trap ball 1002. In other embodiments, one or more of plurality of protrusions 200 of ball control portion 120 on underside 300 of article 100 may bend in different directions when contacting ball 1002. In one embodiment, plurality of protrusions 200 of ball control portion 120 on underside 300 of article 100 may bend in a direction towards forefoot region 10 to trap ball 1002.
In some embodiments, different types of spin may be imparted to ball 1002 by using plurality of protrusions 200 arranged with specific orientations. In one embodiment, ball control portion 120 disposed in different regions of article 100 may include one or more groups of plurality of protrusions 200 oriented in a particular direction. In one embodiment, different portions of ball control portion 120 may include two or more groups of plurality of protrusions 200 oriented in different directions.
Referring now to FIG. 12, ball control portion 120 disposed at midfoot region 12 may include multiple groups of protrusions oriented in different directions. In particular, a first group of protrusions 1100 of plurality of protrusions 200, which are disposed at midfoot region 12 near medial midsection edge 124 on medial side 16, may be oriented in a first direction 1102. A second group of protrusions 1110 of plurality of protrusions 200, which are disposed at midfoot region 12 extending between medial side 16 and underside 300, may be oriented in a second direction 1104. Also, a third group of protrusions 1120 of plurality of protrusions 200, which are disposed at midfoot region 12 of underside 300, may be oriented in a third direction 1106. In other words, the major axis of each protrusion associated with first group of protrusions 1100 may be oriented approximately in first direction 1102. Likewise, the major axis of each protrusion associated with second group of protrusions 1110 may be oriented approximately in second direction 1104. Similarly, the major axis of each protrusion associated with third group of protrusions 1120 may be oriented approximately in third direction 1106. It will be understood that first direction 1102, second direction 1104, and third direction 1106 are only intended to indicate average directions.
In particular, although the major axis of each protrusion of first group of protrusions 1100 may be oriented in slightly different directions from one another, first direction 1102 may characterize the overall direction, or average direction, of the protrusions of first group of protrusions 1100. Similarly, although the major axis of each protrusion of second group of protrusions 1110 and third group of protrusions 1120 may be oriented in slightly different directions from one another, second direction 1104 and third direction 1106 may characterize the overall direction, or average direction, of the protrusions of, respectively, second group of protrusions 1110 and third group of protrusions 1120. Still further, the protrusions disposed between first group of protrusions 1100, second group of protrusions 1110, and/or third group of protrusions 1120 may be oriented in a manner that continuously varies between first direction 1102, second direction 1104, and/or third direction 1106.
In some cases, first direction 1102 may be substantially similar to second direction 1104 and/or third direction 1106. In addition, second direction 1104 may be substantially similar to third direction 1106. In other cases, however, first direction 1102 may be a substantially different direction than either or both second direction 1104 and third direction 1106. Similarly, second direction 1104 may be a substantially different direction than third direction 1106. For example, in one embodiment, first direction 1102 may be a direction oriented close to a longitudinal direction, while third direction 1104 may be a direction oriented close to a lateral direction. In an exemplary embodiment, second direction 1104 may be a direction oriented between first direction 1102 and third direction 1106.
Referring now to FIG. 13, in some embodiments, ball control portion 120 may extend into a portion of underside 300 of article 100. In this embodiment, ball control portion 120 disposed at midfoot region 12 of underside 300 may include multiple groups of protrusions oriented in different directions, as described above. In particular, ball control portion 120 on underside 300 may include third group of protrusions 1120 oriented in third direction 1106. In some embodiments, ball control portion 120 on underside 300 may include a fourth group of protrusions 1200 of plurality of protrusions 200. Fourth group of protrusions 1200, which may be associated with a lateral portion of underside 300 near lateral side 18, may be oriented in a fourth direction 1202. In other words, the major axis of each protrusion associated with fourth group of protrusions 1200 may be oriented approximately in fourth direction 1202. It will be understood that fourth direction 1202 is only intended to indicate an average direction. Similarly, as described above in regard to FIG. 12, while the major axis of each protrusion of fourth group of protrusions 1200 may be oriented in slightly different directions from one another, fourth direction 1202 may characterize the overall direction, or average direction, of the protrusions of fourth group of protrusions 1200.
In some cases, the protrusions of fourth group of protrusions 1200 may be oriented in a manner that continuously varies across ball control portion 120. In one embodiment, the protrusions of fourth group of protrusions 1200 may vary from a direction generally oriented in a direction substantially similar to third direction 1106 at a portion of ball control portion 120 located adjacent to third group of protrusions 1120 to a direction generally oriented in a direction approximately perpendicular to third direction 1106 at a portion of ball control portion 120 located adjacent to an edge of lateral side 18.
Using the arrangements discussed above, ball control portion 120 may be configured to increase grip between a ball and various different regions of article 100. In particular, by applying a plurality of protrusions to selective regions of ball control portion 120 on article 100 corresponding to regions that impact a ball during predetermined types of kicks, ball control portion 120 may be used to enhance the ability of an athlete to apply spin for curving the trajectory of a ball. Still further, by arranging different groups of plurality of protrusions with orientations in different directions, ball control portion 120 may be enhanced for more precise control of the ball trajectory.

By varying the heights of protrusions across different portions of ball control portion 120, different amounts of control over a ball may be provided during contact with ball control portion 120. With this arrangement, protrusions at various portions of ball control portion 120 may be shorter or taller to provide greater or lesser amount of contact with a ball during a kick. Additionally, variation in heights of protrusions across portions of ball control portion 120 may be combined with variation in types of protrusions across portions of ball control portion 120, as discussed above in reference to FIGS. 14 through 18. By varying height, size, shape, rigidity, and/or other physical characteristics of protrusions on a ball control portion, different amounts and/or types of control may be provided when contacting a ball.
Article of footwear 100 may include additional provisions for enhancing traction of upper 102 for purposes of better ball control during kicks. In some cases, an upper may include portions comprising a material that has a high coefficient of friction to provide better grip on a ball during kicks. In other cases, an upper may include structural features on an upper to help enhance friction. For example, in some cases, an upper may include structural features that are intended to increase surface area at a point of contact of the ball which may help enhance traction between the upper and the ball.
Referring now to FIG. 20, upper 102 may include a plurality of recesses 1300 for enhancing traction of upper 102 with a ball. In some embodiments, plurality of recesses 1300 may be disposed in forefoot region 10 of upper 102.

Likewise, plurality of recesses 1300 may include one or more recesses associated with a third size, including a seventh recess 1320 and an eighth recess 1322, which may be associated with a third diameter D3.
In an exemplary embodiment, first diameter D1 may be substantially smaller than second diameter D2 and/or third diameter D3. Similarly, second diameter D2 may be smaller than third diameter D3. In other embodiments, each of first diameter D1, second diameter D2, and/or third diameter D3 may be substantially similar to each other. In one embodiment, the diameter of plurality of recesses 1300 may vary along upper 102 from an area on upper 102 adjacent to lacing gap 116 towards sole structure 106. In an exemplary embodiment, the diameter of plurality of recesses 1300 increases in a direction from an area on upper 102 adjacent to lacing gap 116 towards outer periphery of upper 102 adjacent to sole structure 106. In other words, in FIG. 20, first recess 1302 associated with first diameter D1 is smaller than fourth recess 1310 associated with second diameter D2. Fourth recess 1310 is smaller than seventh recess 1320 associated with third diameter D3. In other embodiments, plurality of recesses 1300 may be arranged on upper 102 with other arrangements of varying diameters.
In one embodiment, plurality of recesses 1300 may be formed on upper 102 using embossing to dispose plurality of recesses 1300 below the surface of upper 102. Similarly, each of first recess 1302, second recess 1304, and/or third recess 1306 may be associated with a first depth 1308. First depth 1308 may be associated with a distance below the surface of upper 102. Likewise, each of fourth recess 1310, fifth recess 1312, and/or sixth recess 1314 may be associated with a second depth 1316. In one embodiment, second depth 1316 may be less than first depth 1308.
