DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-2 illustrate a preferred embodiment of article of footwear 100. For clarity, the following detailed description discusses a preferred embodiment, in the form of an indoor soccer shoe, but it should be noted that the present invention could take the form of any article of footwear including, but not limited to, outdoor soccer shoes, football shoes, rugby shoes, baseball shoes as well as other kinds of shoes. As shown in FIG. 1, article of footwear 100, also referred to simply as article 100, is intended to be used with a right 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 left foot.

Article of footwear 100 preferably includes upper 102. Generally, upper 102 may be any type of upper. In particular, upper 102 could have any design, shape, size and/or color. Preferably, upper 102 is configured to receive a wearer's foot. In this preferred embodiment, upper 102 includes entry hole 103 configured to receive a foot of a wearer.

Referring to FIG. 1, upper 102 includes medial portion 104. Also, upper 102 includes lateral portion 106 disposed opposite of medial portion 104 as seen in FIG. 2. Furthermore, upper 102 includes intermediate portion 108 disposed between medial portion 104 and lateral portion 106. Preferably, intermediate portion 108 corresponds to the instep or vamp of upper 102. In a preferred embodiment, intermediate portion 108 may partially coincide with tongue 197 of upper 102.

In some cases, portions of upper 102 may include one or more pads. Generally, one or more pads may absorb an impact from contact with other objects, including, but not limited to, balls and ground surfaces. A pad could be disposed on any portion of upper 102. In some embodiments, one or more pads could be associated with medial portion 104. In other embodiments, one or more pads could be associated with intermediate portion 108. In a preferred embodiment, one or more pads could be associated with lateral portion 106.

Referring to FIG. 2, lateral portion 106 includes pad 199. In some embodiments, pad 199 may extend over an entire length of lateral portion 106. In a preferred embodiment, pad 199 may extend over a lateral side of toe portion 109 of upper 102. With this arrangement, pad 199 may be configured to absorb impacts from a ball during some types of passing.

In some embodiments, article of footwear 100 may include a fastening system configured to tighten upper 102. Generally, article of footwear 100 could be associated with any type of fastening system including, but not limited to laces, straps, zippers, hook and loop fasteners, as well as other types of fastening systems. In a preferred embodiment, article of footwear 100 may include a lacing system.

Referring to FIGS. 1-3, article 100 includes lace 198 that may be used to tighten upper 102. Preferably, lace 198 is disposed over tongue 197 in lacing portion 110 of upper 102. Lacing portion 110 is configured with first end portion 111 and second end portion 112. First end portion 111 may be disposed adjacent to entry hole 103. Similarly, second end portion 112 may be disposed adjacent to toe portion 109. With this arrangement, lace 198 may tighten lacing portion 110 to secure a foot within upper 102.

Generally, lacing portion 110 may be disposed in any manner on upper 102. In some embodiments, lacing portion 110 may be disposed symmetrically on intermediate portion 108. In a preferred embodiment, lacing portion 110 may be disposed asymmetrically on upper 102. The term “asymmetric” as used throughout this detailed description and in the claims refers to any arrangement of a lacing portion where the lacing portion does not extend symmetrically over the medial portion and the lateral portion of an upper.

Preferably, an asymmetric fastening system may provide greater comfort and a better fit for a wearer. In some cases, a fastening system may be configured with an asymmetrical bias to a lateral portion of an upper. Typically, outdoor soccer players kick the ball on a medial portion of a toe portion. By positioning a fastening system on a lateral portion, the fastening system preferably does not interfere with the power of a kick for an outdoor soccer player. However, indoor soccer players may rely more on finesse than power. In particular, indoor soccer players often use a lateral portion of a toe portion to make short and medium distance passes. For example, a short distance pass made with the lateral portion of the toe portion is often used in a “give and go” passing situation. In a preferred embodiment, a fastening system may be configured with an asymmetrical bias to a medial portion of an upper. Preferably, this asymmetrical bias to the medial portion helps prevent interference between the lacing portion and a ball during finesse passing.

In this embodiment, lacing portion 110 is configured with an asymmetrical bias to medial portion 104. In particular, first end portion 111 of lacing portion 110 is disposed in intermediate portion 108. Furthermore, second end portion 112 is disposed in medial portion 104. With this arrangement, the asymmetrical bias to medial portion 104 preferably provides a better fit that contributes to the finesse capabilities of a wearer of article 100.

For purposes of clarity, only some portions of upper 102 are discussed in this embodiment. It should be understood that upper 102 may include other provisions that are known in the art for assisting in running, kicking or other athletic maneuvers.

Preferably, an article of footwear configured for soccer includes provisions to enhance the trapping abilities of a wearer. During trapping, a wearer of the article of footwear may stop a ball on a toe portion of an article. The wearer of the article may then curl the toe portion of the article to capture the ball between the article and a ground surface. In some embodiments, a flexible material may be used in a sole of an article of footwear to allow a wearer to curl the toe portion of the article. In a preferred embodiment, a sole of an article of footwear may include flexible portions configured to allow a toe portion of a sole to curl.

In the current embodiment, upper 102 is associated with sole system 120. Referring to FIG. 4, sole system 120 includes bottom surface 132. Bottom surface 132 is preferably configured to contact a ground surface, including, but not limited to natural grass or synthetic grass. For the purposes of illustration, the top surface of sole system 120 is not shown in these Figures. Furthermore, in some cases, sole system 120 may include a midsole and/or insole, as well as provisions for traction including, but not limited to cleats and traction elements, that are not illustrated in these Figures for purposes of clarity.

In order to increase the flexibility of article 100, sole system 120 includes two flexing portions. In other embodiments, sole system 120 may include more or less flexing portions. In this embodiment, sole system 120 includes first flexing portion 121 and second flexing portion 122. Preferably, first flexing portion 121 and second flexing portion 122 are disposed in arch portion 150 of sole system 120. In particular, first flexing portion 121 is disposed on medial portion 114 of sole system 120. Likewise, second flexing portion 122 is disposed on lateral portion 116, opposite of medial portion 114, of sole system 120.

In some embodiments, first flexing portion 121 may be separated from second flexing portion 122. In this embodiment, first flexing portion 121 and second flexing portion 122 are separated in a lateral direction by intermediate portion 124 on bottom surface 132. In other embodiments, first flexing portion 121 and second flexing portion 122 may be disposed adjacent to one another.

Although first flexing portion 121 and second flexing portion 122 are disposed in arch portion 150 in the current embodiment, in other embodiments, first flexing portion 121 and second flexing portion 122 could be located in other portions of sole system 120. For example, in another embodiment, first flexing portion 121 and/or second flexing portion 122 could be disposed in toe portion 119 of sole system 120. In still another embodiment, first flexing portion 121 and/or second flexing portion 122 could be disposed in a heel portion of sole system 120.

Generally, first flexing portion 121 and second flexing portion 122 may be configured with any shapes and sizes. In this embodiment, first flexing portion 121 and second flexing portion 122 have substantially similar shapes and sizes. In particular, first flexing portion 121 and second flexing portion 122 have a rounded triangular shape with prominent lobes. Specifically, first flexing portion 121 includes first lobe 141. Similarly, second flexing portion 122 includes second lobe 142. Although second lobe 142 is similar to first lobe 141, second lobe 142 is smaller than first lobe 141. In addition, first flexing portion 121 and second flexing portion 122 are inverted with respect to each other. In other words, first lobe 141 is directed toward toe portion 119 while second lobe 142 faces rearward toward a heel portion of article 100. This arrangement preferably facilitates the curling of toe portion 119 of sole system 120. By providing a means of curling toe portion 119, the finesse abilities of a wearer may be enhanced.

Preferably, first flexing portion 121 and second flexing portion 122 include slots 125. Generally, first flexing portion 121 and second flexing portion 122 may include any number of slots. In some embodiments, first flexing portion 121 and second flexing portion 122 may each include a single slot. In other embodiments, first flexing portion 121 and second flexing portion 122 may include multiple slots. In a preferred embodiment, first flexing portion 121 includes seven slots and second flexing portion 122 includes six slots.

Generally, slots 125 may extend in any direction. In this embodiment, slots 125 may extend in a generally lateral direction. The term “lateral direction” as used throughout this detailed description and in the claims refers to a direction running between a medial portion and a lateral portion of an article of footwear. In other embodiments, however, slots 125 could extend in a longitudinal direction. The term “longitudinal direction” as used throughout this detailed description and in the claims refers to a direction that is perpendicular to the lateral direction. In other words, the longitudinal direction may run between a toe portion and a heel portion of an article of footwear. In still other embodiments, slots 125 could extend in a diagonal direction that is between a lateral direction and a longitudinal direction.

First flexing portion 121 and second flexing portion 122 may be formed in any manner known in the art. In this embodiment, first flexing portion 121 and second flexing portion 122 may be formed by removing at least a portion of sole system 120. Specifically, material may be removed from first flexing portion 121 and second flexing portion 122 to create slots 125. In some embodiments, slots 125 may be filled with a material with a different rigidity than first flexing portion 121 and second flexing portion 122. In some cases, slots 125 may be filled with a more flexible material than first flexing portion 121 and second flexing portion 122. This arrangement may allow slots 125 to compress when a wearer arches article 100 to curl toe portion 119 of sole system 120. In other embodiments, slots 125 may remain hollow. Preferably, slots 125 decrease the rigidity of sole system 120 to provide greater flexibility to sole system 120. With this preferred configuration, slots 125 enable a wearer to bend article 100 with greater ease.

Preferably, first flexing portion 121 and second flexing portion 122 are more flexible than intermediate portion 124. Furthermore, first flexing portion 121 and second flexing portion 122 may be configured to bend independently. For example, in some cases, first flexing portion 121 may be bent more than second flexing portion 122. This difference in the bending of first flexing portion 121 and second flexing portion 122 produces greater curvature in medial portion 114 than lateral portion 116. Likewise, in other cases, second flexing portion 122 may be bent more than first flexing portion 121 to produce greater curvature in lateral portion 116 than medial portion 114. With this arrangement, sole system 120 may accommodate bending, curling and twisting. This preferred arrangement gives greater control to a wearer of article 100 for finesse maneuvers.

Generally, sole system 120 may be constructed of multiple materials. In some embodiments, bottom surface 132 may be constructed of materials typically used for an outsole including, but not limited to elastomers, siloxanes, natural rubber, synthetic rubbers, natural leather, synthetic leather, or plastics. In some cases, first flexing portion 121, intermediate portion 124 and second flexing portion 122 may be constructed of the same material as bottom surface 132. In other embodiments, intermediate portion 124 may be constructed from the same material as bottom surface 132. In addition, first flexing portion 121 and second flexing portion 122 may be constructed with different materials to fine tune the flexing properties of arch portion 150. For example, first flexing portion 121 may be constructed of a material that is more rigid than the material comprising second flexing portion 122. In a preferred embodiment, first flexing portion 121 and second flexing portion 122 may be constructed of a material that is softer and more flexible than conventional material for an outsole. In addition, intermediate portion 124 may comprise conventional material for an outsole. With this preferred arrangement, the flexibility of first flexing portion 121 and second flexing portion 122 in arch portion 150 may be increased to allow article 100 to trap a soccer ball.

Typically, during trapping, a soccer ball may be first received at toe portion 119 of sole system 120. In some cases, toe portion 119 may include provisions for gripping the ball. In a preferred embodiment, toe portion 119 may include a central trapping portion that has a high coefficient of friction for gripping a ball.

In some embodiments, toe portion 119 of sole system 120 may comprise peripheral toe portion 149 and central trapping portion 130. Preferably, peripheral toe portion 149 bounds central trapping portion 130 and extends to the edges of toe portion 119. In this manner, peripheral toe portion 149 may be configured to contact a ground surface while central trapping portion 130 is configured to contact a ball. Preferably, central trapping portion 130 enhances the ability of a wearer to stop and capture the ball in central trapping portion 130.

In some embodiments, peripheral toe portion 149 may be associated with a first coefficient of friction. Likewise, central trapping portion 130 may be associated with a second coefficient of friction. In a preferred embodiment, the second coefficient of friction is greater than the first coefficient of friction. With this arrangement, central trapping portion 130 may be “stickier” than peripheral toe portion 149 to trap a soccer ball.

In order to assist a wearer in trapping a ball, central trapping portion 130 may be configured in any shape and with any size. Examples of various shapes include, but are not limited to, hexagons, squares, rectangles, circles, ovals, polygonal and irregular shapes, as well as any other type of shape. Additionally, central trapping portion 130 may protrude various heights from bottom surface 132. By using different shapes protruding with different heights, trapping portion 130 may be configured to engage and trap a soccer ball.

In this embodiment, central trapping portion 130 is shaped substantially similar to a panel of a soccer ball with a hexagonal shape. The hexagonal shape of central trapping portion 130 is smaller than a panel of a soccer ball. In other embodiments, the hexagonal shape of central trapping portion 130 may be the same size as a panel of a soccer ball. In addition, central trapping portion 130 is generally flush with bottom surface 132. With this configuration, central trapping portion 130 preferably facilitates the trapping of a soccer ball.

In some embodiments, a sole system may utilize a plurality of trapping portions to increase the trapping abilities of a wearer. FIGS. 5-6 are illustrations of an alternative embodiment of article of footwear 500 with multiple trapping portions. In particular, FIG. 5 provides a side view of lateral portion 506 of article of footwear 500. Furthermore, FIG. 6 provides a view of sole system 520 of article 500. In this alternative embodiment, article of footwear 500 is substantially similar to article of footwear 100 of the previous embodiment. However, in this embodiment, multiple trapping portions are disposed on sole system 520. Preferably, this configuration enhances the trapping abilities of a wearer.

Referring to FIG. 6, bottom surface 535 of sole system 520 includes central trapping portion 530. In particular, central trapping portion 530 is disposed in toe portion 519 of sole system 520. Furthermore, central trapping portion 530 is bounded by peripheral toe portion 549 in a manner substantially similar to the previous embodiment. As previously discussed, trapping portions may include any shape. In this embodiment, central trapping portion 530 is configured with a generally circular shape.

Furthermore, sole system 520 includes first trapping portion set 531 and second trapping portion set 532. Generally, first trapping portion set 531 includes a plurality of trapping portions disposed on peripheral portion 550 of sole system 520. Likewise, second trapping portion set 532 includes a plurality of trapping portions that are disposed throughout toe portion 519 and heel portion 510 of sole system 520.

Generally, first trapping portion set 531 and second trapping portion set 532 may include any number of trapping portions. Furthermore, first trapping portion set 531 and second trapping portion set 532 may be associated with any sizes. For example, in this preferred embodiment, first trapping portion set 531 is associated with trapping portions that are larger than the trapping portions of second trapping portion set 532. With this arrangement, first trapping portion set 531 may provide primary contact with a ball or ground surface. In other embodiments, however, the trapping portions of first trapping portion set 531 and second trapping portion set 532 could have substantially similar sizes.

In this embodiment, first trapping portion set 531 and second trapping portion set 532 are smaller than central trapping portion 530. In particular, first trapping portion set 531 and second trapping portion set 532 are configured with generally hexagonal shapes. In other embodiments, first trapping portion set 531 and second trapping portion set 532 could be configured with any other shapes, including, but not limited to hexagons, squares, rectangles, circles, ovals, polygonal and irregular shapes, as well as any other type of shape. Preferably, this arrangement of first trapping portion set 531 and second trapping portion set 532 provide increased opportunities for a wearer to trap a ball at toe portion 549 and heel portion 510.

Generally, bottom surface 535 of sole system 520 may be associated with a first coefficient of friction. Furthermore, central trapping portion 530 may be associated with a second coefficient of friction that is greater than the first coefficient of friction. Preferably, this arrangement enhances the trapping capabilities of central trapping portion 530. In some embodiments, first trapping portion set 531 and second trapping portion set 532 may be associated with a coefficient of friction substantially similar to the second coefficient of friction. In other embodiments, central trapping portion 530, first trapping portion set 531 and second trapping portion set 532 may be configured with different coefficients of friction. By manipulating the frictional properties of central trapping portion 530, first trapping portion set 531 and second trapping portion set 532, the trapping capabilities of article of footwear 500 may be fine tuned.

Preferably, central trapping portion 530, first trapping portion set 531 and second trapping portion set 532 are made of materials substantially similar to the materials discussed in the previous embodiment for central trapping portion 130. In some cases, different materials can be used for central trapping portion 530, first trapping portion set 531 and second trapping portion set 532 in order to adjust the individual frictional properties of each set of trapping portions.

Referring to FIG. 5, first trapping portion set 531 and second trapping portion set 532 may protrude a distance from bottom surface 535 in a similar manner to cleats. By protruding from bottom surface 535, first trapping portion set 531 and second trapping portion set 532 may increase the chances of article 500 stopping and trapping a soccer ball. In some cases, first trapping portion set 531 and second trapping portion set 532 may also be configured to function as low profile cleats for some ground surfaces.

As discussed with respect to FIGS. 1-3, the asymmetric bias of lacing portion 110 preferably allows a soccer player to easily pass a ball using lateral portion 106 of toe portion 109 without interference from lacing portion 110. FIG. 7 is an isometric view of an exemplary embodiment of a wearer of article 100 passing soccer ball 701. It should be understood that this embodiment is intended to be exemplary. In other embodiments, article 100 may contact soccer ball 701 in another manner in order to pass soccer ball 701.

Typically, a wearer will pass or strike the soccer ball with lateral portion 106 of toe portion 109 of article of footwear 100. In this embodiment, lacing portion 110 does not contact soccer ball 701 when lateral portion 106 of toe portion 109 contacts soccer ball 701 in order to pass soccer ball 701. Preferably, this configuration of lacing portion 110 with an asymmetrical bias to medial portion 104 does not interfere with the passing of soccer ball 701 using lateral portion 106.

As previously discussed, article 100 includes pad 199 disposed on lateral portion 106 of toe portion 109. When lateral portion 106 of toe portion 109 contacts soccer ball 701 in order to pass soccer ball 701, pad 199 may absorb some of the impact of soccer ball 701. With this arrangement, pad 199 may assist a wearer when passing or striking soccer ball 701 by buffering some of the force of the pass or strike of soccer ball 701. In addition, pad 199 provides a firm surface to contact soccer ball 701 when passing or striking with lateral portion 106 of toe portion 109. This firm surface preferably provides an effective contact point to generate power and agility during striking or passing soccer ball 701.

In some cases, a wearer of article of footwear 100 may catch a pass in order to trap a soccer ball. FIGS. 8-11 illustrate an exemplary embodiment of a wearer of article of footwear 100 trapping soccer ball 801. The scenario illustrated in this embodiment is intended to be exemplary. In other embodiments, a wearer of article of footwear 100 may trap soccer ball 801 in another manner.

Referring to FIGS. 8-9, soccer ball 801 is preferably stopped by toe portion 119 of sole system 120. In particular, central trapping portion 130 contacts soccer ball 801 in order to stop soccer ball 801. In other embodiments, however, soccer ball 801 may be trapped by other portions of article of footwear 100.

Referring to FIG. 9, central trapping portion 130 may be clearly seen contacting soccer ball 801. For purposes of clarity, soccer ball 801 is shown in phantom. Preferably, the relatively high coefficient of friction of central trapping portion 130 facilitates a wearer of article 100 in trapping soccer ball 801. In particular, central trapping portion 130 may be configured to stick to a portion of soccer ball 801 and prevent any further rolling of soccer ball 801 beneath article 100.

As previously discussed, in order to firmly trap a soccer ball, a wearer may curl a toe portion of an article of footwear toward the soccer ball. This allows the soccer ball to be compressed between a ground surface and the article. Referring to FIGS. 10-11, a wearer arches article of footwear 100 to firmly trap soccer ball 801. In particular, as a wearer traps soccer ball 801, first flexing portion 121 is disposed adjacent to top portion 1002 of soccer ball 801. With this arrangement, toe portion 119 curls toward soccer ball 801 to push soccer ball 801 toward a ground surface. In some cases, a heel portion of article 100 may also bend toward soccer ball 801.

Referring to FIG. 11, soccer ball 801 is illustrated in phantom so that bottom surface 132 of sole system 120 is visible. In this embodiment, as toe portion 119 curls around soccer ball 801, first flexing portion 121 and second flexing portion 122 arches upward. Preferably, slots 125 contract to allow first flexing portion 121 and second flexing portion 122 to bend.

In this example, first flexing portion 121 and second flexing portion 122 may experience different degrees of bending. Specifically, first flexing portion 121 may bend more than second flexing portion 122. In this case, since first flexing portion 121 is disposed adjacent to top portion 1002 of soccer ball 801 as seen in FIG. 10, first flexing portion 121 may undergo bending to conform to the curvature of top portion 1002 of soccer ball 801. Likewise, since second flexing portion 122 is disposed further from top portion 1002 of soccer ball 801, second flexing portion 122 may undergo less bending than first flexing portion 121. Preferably, this configuration allows a wearer of article of footwear 100 to exert greater control to compress soccer ball 801 toward a ground surface and effectively trap soccer ball 801.

In embodiments where a toe portion of an article is used for striking a ball, the article can include provisions for increasing accuracy and power to facilitate striking the ball. In some embodiments, an article of footwear can include a toe bumper that increases the surface area of a toe portion to assist with passing and striking a ball. In some cases, a toe bumper may be configured as part of an upper of an article of footwear. In a preferred embodiment, a toe bumper may be configured as part of a sole system of an article of footwear.

FIGS. 12-14 illustrate a preferred embodiment of article of footwear 1200 including provisions for contacting a ball at a toe portion of article 1200. In this embodiment, article of footwear 1200 includes upper 1202 and sole system 1220. Generally, upper 1202 can be any type of upper with any design, shape, size and/or color. In this case, upper 1202 includes medial portion 1204 and lateral portion 1206. In addition, upper 1202 includes intermediate portion 1208 disposed between medial portion 1204 and lateral portion 1206. Also, upper 1202 includes toe portion 1209. For purposes of clarity, only some portions of upper 1202 are discussed in this embodiment.

Sole system 1220 includes front portion 1226. In particular, front portion 1226 may extend upward from a bottom surface of sole system 1220. This configuration may dispose front portion 1226 adjacent to toe portion 1209 of upper 1202. With this configuration, front portion 1226 can contact a ball during striking or passing.

In some embodiments, front portion 1226 of sole system 1220 may include toe bumper 1229. Generally, toe bumper 1229 may be disposed adjacent to toe portion 1209 of upper 1202. Furthermore, toe bumper 1229 may extend from lateral portion 1206 to medial portion 1204 of toe portion 1209. In a preferred embodiment, toe bumper 1229 may be configured with a shape that increases the surface area of front portion 1226 to assist in contacting a ball during passing or striking.

Generally, a toe bumper can be configured with any shape to increase the surface area of a front portion and/or toe portion of an article. In some embodiments, a toe bumper may be configured with a generally symmetric shape. In other words, a toe bumper may cover a medial portion and a lateral portion of an article in a substantially similar manner. For example, a toe bumper may be configured with a curved shape that generally follows the contours of a toe portion of an article. In other embodiments, a toe bumper can be configured with an asymmetrical shape. In some cases, a toe bumper may be configured with an asymmetrical shape that provides more surface area on a medial portion than a lateral portion of an article. In other cases, a toe bumper can include an asymmetrical shape with more surface area on a lateral portion than a medial portion of an article. In a preferred embodiment, a toe bumper is configured with an asymmetrical shape that includes a protrusion.

In this preferred embodiment, toe bumper 1229 includes protrusion 1227 that extends outward slightly from toe portion 1209 with a generally convex shape, as illustrated in FIG. 14.

Similarly, flattened curved portion 1242 can be associated with medial portion 1204.

Preferably, standard curved portion 1241 and flattened curved portion 1242 may be associated with different types of curvature. In particular, flattened curved portion 1242 includes a generally flat shape that may be associated with less surface area than a curved shape. Furthermore, standard curved portion 1241 is configured with a curved shape that is configured to follow the contour of toe portion 1209. This asymmetrical arrangement of toe bumper 1229 can provide a greater surface area for standard curved portion 1241 associated with lateral portion 1206. This arrangement can be particularly helpful for indoor soccer players using lateral portion 1206 of toe portion 1209 to make short and medium distance passes in a “give and go” passing situation. By creating more surface area, standard curved portion 1241 can provide better accuracy for a player passing a ball with lateral portion 1206 of toe portion 1209.

In different embodiments, toe bumper 1229 can be made of different materials. In some cases, toe bumper 1229 can be made of a material that is generally stiffer than the material used for sole system 1220. In other cases, toe bumper 1229 can be made of a softer material than the material used for sole system 1220.

In this embodiment, arch portion 1750 of sole system 1220 includes first slot portion 1751 and second slot portion 1752.

Generally, the location of first slot portion 1751 and second slot portion 1752 may vary. In some embodiments, first slot portion 1751 and second slot portion 1752 may be associated with medial portion 1754 of sole system 1220. In other embodiments, first slot portion 1751 and second slot portion 1752 may be associated with lateral portion 1756 of sole system 1220. In a preferred embodiment, first slot portion 1751 and second slot portion 1752 may be associated with medial portion 1754 of sole system 1220. In particular, first slot portion 1751 is disposed adjacent to forefoot portion 1709 of sole system 1220. Likewise, second slot portion 1752 is disposed adjacent to heel portion 1710 of sole system 1220. Furthermore, first slot portion 1751 and second slot portion 1752 may be coextensive with periphery portion 1755 of bottom surface 1735. As a result, first slot portion 1751 and second slot portion 1752 may provide a recessed periphery portion 1755 of bottom surface 1735, as shown in FIG. 17. Periphery portion 1755 may be recessed in a direction extending between medial portion 1754 and lateral portion 1756. Using this configuration, arch portion 1750 can compress inward at first slot portion 1751 and second slot portion 1752 to enable bending of arch portion 1750.

In this embodiment, first slot portion 1751 is separated from second slot portion 1752 by separating portion 1753. As shown in FIG. 17, first slot portion 1751, second slot portion 1752, and separating portion 1753 may form a continuous recessed periphery portion 1755 of bottom surface 1735. The recessed periphery portion 1755 may be located in arch portion 1750. Generally, separating portion 1753 may be configured with any shape. Examples of different shapes for a separating portion include, but are not limited to, triangular shapes, rectangular shapes, trapezoidal shapes, elliptical shapes, regular shapes, irregular shapes, as well as other types of shapes. In a preferred embodiment, separating portion 1753 is configured with a generally rectangular shape.

Generally, slot portions can be configured with any shape to facilitate the curling of a toe portion of a sole system. In some embodiments, slot portions can be configured with shapes that allow a medial portion and a lateral portion of a sole system to bend in a substantially similar manner. In a preferred embodiment, slot portions can be configured with shapes that allow a medial portion and a lateral portion to bend in different manners.

In some embodiments, first slot portion 1751 and second slot portion 1752 can have substantially similar shapes. In other embodiments, first slot portion 1751 and second slot portion 1752 can have different shapes. In a preferred embodiment, first slot portion 1751 and second slot portion 1752 can have substantially similar shapes.

In this preferred embodiment, first slot portion 1751 and second slot portion 1752 may be approximately V-shaped. In particular, first slot portion 1751 includes first narrow portion 1761 and first wide portion 1771.

Preferably, first wide portion 1771 and second wide portion 1772 cover a greater area than first narrow portion 1761 and second narrow portion 1762. Since first wide portion 1771 and second wide portion 1772 cover a greater area than first narrow portion 1761 and second narrow portion 1762, first wide portion 1771 and second wide portion 1772 may be configured to compress inward to a greater degree than first narrow portion 1761 and second narrow portion 1762. This can allow medial portion 1754 to bend more than lateral portion 1756. With this preferred configuration, first slot portion 1751 and second slot portion 1752 may also facilitate twisting of forefoot portion 1709 with respect to heel portion 1710, which can result in a more effective trapping of a ball.

Generally, the orientation of one or more slot portions can vary. In this embodiment, first slot portion 1751 and second slot portion 1752 extend in a generally lateral direction. In other embodiments, first slot portion 1751 and second slot portion 1752 may extend in other directions. In some cases, the orientation of first slot portion 1751 and second slot portion 1752 can be changed in order to fine tune the flexing properties of arch portion 1750.

First slot portion 1751 and second slot portion 1752 may be formed in any manner known in the art. In some embodiments, material from sole system 1220 may be removed to form first slot portion 1751 and second slot portion 1752. In some cases, only a portion of a sole system 1220 may be removed to form first slot portion 1751 and second slot portion 1752. For example, an outsole of sole system 1220 can be removed to form first slot portion 1751 and second slot portion 1752. As a result, at least a portion of upper 1202 may be exposed through the first slot portion 1751 and the second slot portion 1752, as shown in FIG. 17. In other words, at least the first slot portion 1751 and the second slot portion 1752 may form an opening through the bottom surface of the sole system so that a portion of upper 1202 may be exposed through the opening. In this preferred embodiment, first slot portion 1751 and second slot portion 1752 are integrally formed with sole system 1220. With this arrangement, arch portion 1750 is configured with a shape that can compress inward to enable bending of arch portion 1750. This bending can facilitate the curling of toe portion 1719 of sole system 1220.

In some embodiments, a sole system may also include provisions for increasing the flexibility of the forefoot and heel portions of an article.

Typically, a wearer may use a toe portion of an article of footwear to pass or strike a soccer ball. In some cases, a wearer may use a lateral portion of a toe portion to make short and medium distance passes in a “give and go” passing situation. As discussed with respect to FIGS. 12-14, an asymmetrical toe bumper can provide greater surface area to contact a ball on a lateral portion of a toe portion.

FIG. 22 illustrates an isometric view of an exemplary embodiment of a wearer of article 1200 passing soccer ball 2001. It should be understood that this embodiment is intended to be exemplary. In other embodiments, article 1200 may contact soccer ball 2001 in another manner in order to pass soccer ball 2001.

In this embodiment, a wearer of article 1200 contacts soccer ball 2001 with toe bumper 1229 disposed on front portion 1226 of sole system 1220. Specifically, standard curved portion 1241 disposed on lateral portion 1206 of toe bumper 1229 contacts soccer ball 2001. With textured surface 1243 on toe bumper 1229, standard curved portion 1241 preferably engages and grips soccer ball 2001.

In this preferred embodiment, standard curved portion 1241 preferably comprises a larger surface area due to the configuration of protrusion 1227 on toe bumper 1229. This greater surface area of standard curved portion 1241 can provide a stable contact point with soccer ball 2001. With this greater surface area as a stable contact point, a wearer of article 1200 can have greater accuracy when passing or striking soccer ball 2001 with standard curved portion 1241 of toe bumper 1229.

It is also possible that a wearer of an article configured for indoor soccer may pass or a strike a soccer ball with a medial portion of a heel portion of an article. An article can be configured with a heel bumper disposed on a medial portion of a heel portion to pass or strike a soccer ball, as illustrated in FIG. 15. FIG. 23 illustrates an exemplary embodiment of a wearer of article of footwear 1200 contacting soccer ball 2101 with heel bumper 1502. This embodiment is intended to be exemplary. In other embodiments, heel bumper 1502 can contact soccer ball 2101 in another manner.

Typically, only a portion of soccer ball 2101 may contact medial portion 1204 of heel portion 1520 during a heel pass. With a generally rounded triangular shape, heel bumper 1502 is configured with an asymmetrical shape that agrees with the shape of a portion of soccer ball 2101 that may contact medial portion 1204 of heel portion 1520 during a heel pass. Preferably, the asymmetrical shape of heel bumper 1502 facilitates contact with soccer ball 2101.

When heel bumper 1502 contacts soccer ball 2101, heel bumper 1502 preferably absorbs some of the impact of soccer ball 2101. Furthermore, a high coefficient of friction associated with textured surface 1543 of heel bumper 1502 can assist a wearer of article 1200 to engage soccer ball 2101 with heel bumper 1502. With this configuration, heel bumper 1502 provides an effective contact point to generate power and agility when striking or passing soccer ball 2101.

As previously discussed, a wearer of an article of footwear may catch a pass in order to trap a soccer ball. FIGS. 24-27 illustrate an exemplary embodiment of a wearer of article of footwear 1200 trapping soccer ball 2201. The scenario illustrated in this embodiment is intended to be exemplary. In other embodiments, a wearer of article of footwear 1200 may trap soccer ball 2201 in another manner.

Referring to FIG. 24, soccer ball 2201 is stopped by toe portion 1719 of sole system 1220. In particular, central trapping portion 1730 contacts soccer ball 2201 to stop soccer ball 2201. Typically, the relatively high coefficient of friction of central trapping portion 1730 assists a wearer of article 1200 to trap soccer ball 2201. This configuration can enable central trapping portion 1730 to stick to a portion of soccer ball 2201 and prevent any further rolling of soccer ball 2201 beneath article 1200. In other embodiments, however, soccer ball 2201 may be trapped by other portions of article of footwear 1200.

As previously discussed, in order to firmly trap a soccer ball, a wearer may curl a toe portion of an article of footwear toward the soccer ball. This allows the article to compress the soccer ball between a ground surface and the article. Referring to FIGS. 25-27, a wearer curls toe portion 1719 to firmly trap soccer ball 2201. This configuration can dispose arch portion 1750 adjacent to top portion 2202 of soccer ball 2201, as illustrated in FIG. 25. In particular, medial portion 1754 of arch portion 1750 may be disposed adjacent to top portion 2202 of soccer ball 2201 while lateral portion 1756 of arch portion 1750, not visible in FIG. 25, is disposed further from top portion 2202 of soccer ball 2201.

Referring to FIG. 26, soccer ball 2201 is illustrated in phantom so that bottom surface 1735 of sole system 1220 is visible. As a wearer traps soccer ball 2201, arch portion 1750 may arch upward. This can be accomplished by the inward compression of first slot portion 1751 and second slot portion 1752. With this inward compression, arch portion 1750 can arch upward and conform to the curvature of soccer ball 2201. This can allow arch portion 1750 greater control when trapping soccer ball 2201. By conforming to the curvature of soccer ball 2201, arch portion 1750 can exert greater control in compressing soccer ball 2201 toward a ground surface.

In this preferred embodiment, first slot portion 1751 and second slot portion 1752 are configured with shapes that cover a greater area on medial portion 1754 than lateral portion 1756 of sole system 1220. This configuration allows medial portion 1754 of arch portion 1750 to compress inward to a greater degree than lateral portion 1756. This can cause medial portion 1754 to bend to a greater degree than lateral portion 1756. Since a wearer of article 1200 may trap soccer ball 2201 with medial portion 1754 of arch portion 1750 disposed adjacent to top portion 2202 of soccer ball 2201, as illustrated in FIG. 25, the greater bending of medial portion 1754 can allow a wearer to exert greater control of soccer ball 2201. In other words, medial portion 1754 may undergo greater bending to conform to the curvature of top portion 2202 of soccer ball 2201. Similarly, lateral portion 1756 of arch portion 1750 may be disposed further from top portion 2202 of soccer ball 2201. Since lateral portion 1756 may bend to a lesser degree than medial portion 1754, arch portion 1750 may twist as well as arch to conform to the curvature of soccer ball 2201. Preferably, this configuration allows a wearer of article of footwear 1200 to exert greater control to compress soccer ball 2201 toward a ground surface and effectively trap soccer ball 2201.

Preferably, heel portion 1710 as well as forefoot portion 1709 may also bend to firmly trap soccer ball 2201. In this embodiment, forefoot flexing groove set 1784 and heel flexing groove set 1794 compress inward to allow forefoot portion 1709 and heel portion 1710, respectively, to bend to conform to the curvature of soccer ball 2201, as illustrated in FIGS. 25-27. With this arrangement, bottom surface 1735 can conform to the curvature of soccer ball 2201 and push soccer ball 2201 toward a ground surface to firmly trap soccer ball 2201.

Referring to FIG. 27, outsole 1902 of sole system 1220 is illustrated in phantom so that insole 1901 is visible within sole system 1220. As a wearer traps soccer ball 2201 and outsole 1902 conforms to a curvature of soccer ball 2201, insole 1901 preferably cooperates with provisions for flexibility disposed on outsole 1902. In particular, grooves of second insole groove set 1915 of arch portion 1950 compress inward to allow arch portion 1950 to arch upward. This arching cooperates with the upward arching of arch portion 1750 of outsole 1902. In addition, grooves of first insole groove set 1984 compress inward to allow toe portion 1919 to curl downward. With this configuration, toe portion 1919 can bend in a cooperating manner with toe portion 1719 of outsole 1902. Preferably, this configuration assists outsole 1902 to conform to the curvature of soccer ball 2201 and trap soccer ball 2201.

While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
