ARTICLE OF FOOTWEAR WITH INTERCHANGEABLE BOOTIE

BACKGROUND OF THE INVENTION

1. Field of the Invention.

[0001] The invention relates to articles of footwear, and more particularly, articles of footwear having replaceable booties with ball control elements.

2. Background of the Invention.

[0002] Many sports require interaction between an athletic shoe upper and another surface. For example, in soccer, rugby, and football, players kick a ball with their foot. The point of contact where the athletic shoe touches the other surface can be referred to as an interaction surface. In addition, in rock climbing, a climber relies on friction from different portions of climbing shoes. In the past, participants in these sports were limited by the shoe they are wearing. Each pair of shoes was limited to have only one type of interaction surface.

[0003] Recently, ball control elements have been introduced. Ball control elements can be attached to a shoe to create a shoe that has a modified interaction surface. For example, a soccer style shoe having a ball control element on the foreheel can have a refined kicking performance at the forefoot portion. For example, Japanese Patent Number JP9140402, to Saburo, is directed to an athletic shoe having ball control elements that are placed within the upper, however, the athletic shoe of Saburo only has one set of ball control elements.

[0004] Some athletic shoes are designed to receive inserts to accommodate changes in running styles or to replace treads. For example, U.S. Patent Number 6,023,859, to Burke et al. discloses a shoe that receives sole inserts. The sole inserts can be replaced and configured for different

running styles, like over-pronation. The inserts extend through holes in the sole, and are inserted from outside the shoe.

[0046] Foot cover 210 and foot pad 220 are preferably configured to receive a foot. Foot cover 210 is generally designed to engage a top portion of a foot and foot pad 220 is generally designed to engage a bottom portion of the foot. In some embodiments, foot cover 210 preferably covers only a portion of the foot. In other embodiments, foot cover 210 can cover the entire foot. For example, referring to FIG. 1 , bootie 110 illustrates an embodiment in which bootie 110 includes upper 115 that covers and secures a complete circumference of a portion of a foot. In some embodiments, a bootie can use straps, ties, flaps, toe holds, ankle wraps, or any other suitable device to secure the bootie to a foot.

[0047] Returning to FIG. 2, foot pad 220 provides support for a foot. Preferably, foot pad 220 is sized to correspond with a particular size of foot. Accordingly, foot pad 220 provides a surface that can accommodate the heel, toes, instep, and ball portion of a particular size of foot.

[0048] In some embodiments, bootie 200 can be configured to be worn as a slipper or sandal when not inserted into a shell. Accordingly, bootie 200 can be comfortably worn without a shell. For example, an athlete can wear bootie

200 until game time, or during an intermission, and then insert bootie 200 into a shell configured to receive bootie 200.

[0049] In other embodiments, a foot pad portion of a bootie could cover less than the bottom of the foot to be received. For example, in some embodiments, a foot pad may only cover the toes and balls of the foot. Other embodiments may provide support to only a select portion of the bottom of the foot.

[0050] FIG. 3 is a schematic diagram of bottom 230 of foot pad 220. Bottom 230 can include provisions to increase comfort and to improve its ability to associate with shell 120.

In another example, an embodiment can include an article having only medial ball control elements. Preferably, ball control elements are provided at portions of the upper that may contact another surface.

[0078] Preferably, a user can select a particular bootie from a number of available candidate booties. Preferably, all of the candidate booties of a particular size, or range of sizes, are configured to associate with a corresponding shell of a matching size. In other words, a shell of a particular size is configured to receive multiple candidate booties of a compatible size. Each bootie can be selected by the user according to the type of ball control elements on the bootie. For example, some ball control elements can have a greater stickiness to work with a certain type of ball. Other ball control elements can be preferably used in different types of weather. For example, a user can have a choice between a dry-use bootie, a wet-use bootie, and a mud bootie.

[0079] In addition to different ball control elements, different booties can preferably have different structural properties to allow for foot size differences. For example, if a user chooses a size 10 article, the user may find the fit too

loose. The user can then use a bootie that has a thicker foot cover to compensate. Likewise, an article that is too tight can receive a bootie having a thinner foot cover. Thus, an individual article can receive different booties to have a different fit for a user.

[0080] Other structural differences can include the amount of foot covered. For example, foot cover 210 of FIG. 2 may only cover a top or toe portion of a foot. Other embodiments can include booties that surround the foot. A bootie that surrounds the foot can provide more area for ball control elements. In addition, a full foot bootie can keep the foot warm or dry, depending on the embodiment.

[0081] In addition to different bootie embodiments, the user can select from different embodiments of shells. In various embodiments, the user may desire a shell having large cleats, small cleats, or any other arrangement of cleats. In addition, some embodiments can have booties with high tops or low tops. In another embodiment, a shell may be provided that is light weight. Accordingly, the user can ultimately select an article of footwear from both a bootie and a shell.

Different embodiments of article 900 can receive any number of different booties to possess different types of lateral, medial and lace ball control elements.

[0087] Assembled article 916 includes bootie 810 associated with shell 910. As can be observed, the ball control elements of bootie 810 extend through shell 910. Shoelace 970 is illustrated as being received in lace receiving element 838. In some embodiments, however, lace receiving

element 838 may not be employed to allow for faster removal of a bootie from a shell.

[0088] While a complete article of footwear or a shell may be expensive, sets of booties can be considerably cheaper. Therefore, the intended user need only purchase one shell, and may then purchase many different bootie sets. Different bootie sets allows the user a wide range of variations in fit and ball control element styles by wearing different booties with a shell. Additionally, because changing from one bootie set to another bootie set is easy, the user can change article characteristics at any time. For example, if rain develops just before a game begins, the user of the article can easily switch from a dry weather bootie to a wet weather bootie. [0089] FIG. 10 is a schematic diagram of a preferred embodiment of ball control element 1110. Referring to FIG. 10, ball control element 1110 is provided on bootie 1130. Ball control element 1110 is shown as being received in shell 1120. Outer surface of ball control element is preferably flush with the outer surface of shell 1120.

[0090] FIG. 11 is a schematic diagram of a preferred embodiment of ball control element 1210. Referring to FIG. 11 , ball control element 1210 is provided on bootie 1230. Ball control element 1210 is shown as being received in bootie 1220. Outer surface of ball control element preferably extends outward from the outer surface of bootie 1220. [0091] FIG. 12 is a diagram of a system of selecting an article of footwear according to an embodiment. Referring to FIG. 12, a user can select from several different elements to create a custom article of footwear. As can be observed, the user can choose from first bootie 1010, second bootie 1020, third bootie 1030, or fourth bootie 1040. However, any number of different booties can be available for the user to choose.

[0092] Each of first bootie 1010, second bootie 1020, third bootie 1030, and fourth bootie 1040 can have different arrangements and properties. For

example, according to an embodiment, first bootie 1010 can have dry weather ball control elements. On the other hand, the user can select second bootie 1020 because second bootie 1020 is an embodiment having ball control elements designed for wet weather. It can also be observed that first and second bootie 1010 and 1020 have a partial foot cover. [0093] On the other hand, the user may also choose from the styles of third bootie 1030 and fourth bootie 1040. Third bootie 1030 and fourth bootie 1040 both have full covered foot areas. In one embodiment, third bootie 1030 can be water proof and have wet weather capable ball control elements. Similarly, fourth bootie 1040 can be thicker to create a snugger fit. Fourth bootie 1040 can also have dry weather ball control elements. [0094] In some embodiments, a system of selecting an article of footwear can include different provisions to cushion a foot. For example, in some embodiments, different booties may include cushion portions. The configuration of a cushioning portion for a bootie can depend on an intended playing condition. In some embodiments, a dry weather bootie may have more cushioning than a wet weather embodiment. Preferably, a dry weather bootie such as first bootie 1010 can include a cushion portion, for example cushion 240 of FIG. 3. Preferably, a wet weather bootie such as third bootie 1030 has no cushioning element.

[0095] First shell 1050 and second shell 1060 are preferably configured to associate first bootie 1010, second bootie 1020, third bootie 1030, and fourth bootie 1040. Preferably, first shell 1050 and second shell 1060 have ball control element receiving portions that correspond to ball control elements on first bootie 1010, second bootie 1020, third bootie 1030, and fourth bootie 1040. Accordingly, the user can choose from either of first shell 1050 and second shell 1060 into which any of first bootie 1010, second bootie 1020, third bootie 1030, and fourth bootie 1040 can be inserted and worn.

[0096] In addition, first shell 1050 can be an embodiment having large cleats that are spaced apart while second shell 1060 has smaller cleats that are spaced closer together. It can also be observed that second shell 1060 is a high top model while first shell 1050 is a low top model.

[0097] Different combinations of first bootie 1010, second bootie 1020, third bootie 1030, or fourth bootie 1040 and first shell 1050 or second shell 1060 can be associated to create different articles of footwear. It can be observed that third bootie 1030 and first shell 1050 have been joined to create article 1070. Accordingly, article 1070 has a large cleats and a full foot cover area with dry weather ball control elements.

[0098] However, it can be understood that in a preferred embodiment, the user can have many more options available. The options can include many different styles of booties and shells.

[0099] FIG. 13 is an illustration of a preferred embodiment of a retail system. Referring to FIG. 13, shells 1310 are sold simultaneously sold with booties 1320. In this embodiment, the retail system is a wall section. In a preferred embodiment, this wall would be a portion of a sneaker section in a store. Shells 1310 and booties 1320 are shown generically in FIG. 13 only for the purpose of illustration. In some embodiments, these shells and booties can be different styles, colors, and arrangements of ball control elements.

[00100] In addition, in a preferred embodiment, shells 1310 can be prepackaged in boxes 1330. Boxes 1330 can contain a set of shells that are marked for shoes size, cleat or tread style, and footwear style, such as hightops or running shoes. Shells 1310 are illustrated as being sold in boxes 1330, however shells 1310 can be sold in any style, packaging, or manner desired.

[00101] Packages of booties 1320 can be sold along side boxes 1330. FIG. 13 illustrates an example in which booties 1320 are sold in plastic hanging packages. For example, booties could be sold in packages, including

wet bootie packages 1340, power shoe bootie packages 1342, and dry use bootie packages 1344. However, booties 1320 can be sold in any arrangement or packaging desired. The retail wall system of FIG. 13 allows the user to easily purchase different shell styles and their respective booties. [00102] Using a retail system, a user could select a shell and select booties from a group of candidate bootie sets that have been prepackaged. By associating a bootie of the selected bootie candidate group with a selected shell, the user has a modified article of footwear to provide varying degrees of fit, appearance, and ball control.

[00103] In some situations, it may be preferable for a user to purchase multiple pre-packaged bootie sets at one time. Using a retail system, such as the embodiment illustrated in FIG. 13, a user could purchase two different shells 1310 and two different booties 1320. This purchase would provide the user with four different variations in the type of article of footwear that could be obtained through the interchange of booties 1320 and shells 1310. [00104] Referring to FIGS. 12 and 13, a user can be likewise be presented with a retail system where first bootie 1010, second bootie 1020, third bootie 1030, or fourth bootie 1040 can be presented in wet bootie packages 1340, power shoe bootie packages 1342, and dry use bootie packages 1344 and first shell 1050 and second shell 1060 are presented in boxes 1330. In a retail system having four bootie styles and two shell styles, the user is provided with eight different variations of an article of footwear without the expense of purchasing eight different articles of footwear.

[00105] In addition, in another embodiment of the retail system, first bootie 1010, second bootie 1020, third bootie 1030, or fourth bootie 1040 can be sold having different appearances. By selecting different booties, the user may change the appearance of completed article of footwear 1070. For example, each of first bootie 1010, second bootie 1020, third bootie 1030, or fourth bootie 1040 can have different colors, patterns, logos, or customized

appearances. Similarly, in some embodiments, shells may also be provided that have different appearances.

[00106] In some embodiments, a retail system can include provisions to customize an article of footwear or a bootie. For example, in some embodiments, a customized appearance article may be selected from a website. A customer may select custom colors, writing, control element, stitching, and patterns to be provided on a custom article of footwear or bootie. For example, commonly assigned U.S. patent application serial number 09/721 ,445, filed Nov. 11 , 2000, describes a custom fit system. [00107] In some embodiments, a retail system may include provisions to retrieve either of a custom article of footwear or bootie. For example, a customer's foot may be measured. The customer's measurements can then be stored in a database. The customer can then purchase a custom fit or preferred fit article of footwear by accessing the database. For example, a customer's preferred fit may be provided on a portable storage device or access card. For example, a customer may simply access an account on a website. Preferably, a customer may simply provide an ID card at retail location to receive custom fit or preferred fit articles of footwear and booties. Commonly assigned U.S. patent publication 2007/003750, filed on August 12, 2005, published on February 15, 2007, describes an online retail system and a customer database. The methods and systems described in the two prior applications could be adapted for use with embodiments of the retail system and articles of footwear and booties described above. U.S. patent publication 2007/003750 and U.S. patent application Ser. No. 09/721 ,445 are incorporated by reference in their entirety.

[00108] Accordingly, various embodiments of the present invention will help a user to control the interaction of an article of footwear with surfaces. A user can change booties to change the surface interaction quality of the article. In addition, an article of footwear can be provided with a number of compatible

booties to change the fit, feel, appearance, and behavior of the article. Thus, the present invention provides an elegant solution by allowing an article of footwear to have many different qualities at a lower cost than purchasing separate articles of footwear.

[00109] While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that may more embodiments and implementations are possible that are within the scope of the invention.
