## Background
This application is a continuation of U.S. Patent Publication Number US 2009/0100712 A1, published Apr. 23, 2009 (U.S. patent application Ser. No. 11/876,190, filed Oct. 22, 2007), which is herein incorporated by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to articles of footwear, and more particularly, articles of footwear having replaceable ball control elements.
2. Background of the Invention
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.
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 forefoot and/or instep 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.
Some athletic shoes are designed to receive inserts to accommodate changes in running styles or to replace treads. For example, U.S. Pat. No. 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 openings in the sole, and are inserted from outside the shoe.

Using an interference fit, the insert can be secured by friction between portions of the insert and portions of the article.
Referring to FIGS. 2-4, insert 1410 may be associated with outer tongue 1510 and inner tongue 1550. Preferably, insert 1410 is received between inner tongue 1550 and outer tongue 1510. This arrangement allows insert 1410 to be sandwiched between outer tongue 1510 and inner tongue 1550, as seen in FIG. 3. In particular, backing 1450 preferably rests against the inner facing surface of outer tongue 1510 and the outer facing surface of inner tongue 1550. Furthermore, as shoelace 1580 is tightened and tied with knot 1720 following the insertion of foot 1710, outer tongue 1510 and inner tongue 1550 may apply tension to insert 1410 in order to keep insert 1410 in place, as seen in FIG. 17.2.
Preferably, ball control elements 1420, 1430 and 1440 may be disposed on an outer surface of upper 1560. In some embodiments, outer tongue 1510 may include openings or similar provisions to receive ball control elements 1420, 1430 and 1440. In this embodiment, first opening 1520, second opening 1530, and third opening 1540 are preferably disposed in outer tongue 1510. In this case, first ball control element 1420, second ball control element 1430, and third ball control element 1440 can preferably be received in respective first opening 1520, second opening 1530, and third opening 1540. In other embodiments, other arrangements of voids, windows, or openings can be provided to receive ball control elements provided on an insert. Using this preferred arrangement, ball control elements 1420, 1430 and 1440 can each be observed on an outer surface of article 1500.
In some embodiments, the sizes of openings configured to receive ball control elements may be varied. In some cases, the openings may be smaller than the ball control elements to reveal only a portion of the ball control elements along an outer surface of the upper. In other cases, the openings can be larger than the ball control elements. In a preferred embodiment, the openings can have a size that facilitates an interference fit with the ball control elements. In other words, the openings have a size equal to or slightly less than the associated ball control elements.
Referring to FIGS. 6-8, in the current embodiment, the sizes of the ball control elements may be substantially similar to the sizes of the openings in order to facilitate an interference fit. In this embodiment, insert 1810 preferably includes first ball control element 1820, second ball control element 1830, and third ball control element 1840 provided on backing 1850, as seen in FIG. 5. First ball control element 1820 preferably has first length 1860 and first width 1862. Likewise, second ball control element 1830 preferably has second length 1870 and second width 1872. Also, third ball control element 1840 preferably has third length 1880 and third width 1882.
Referring to FIGS. 7-8, first opening 1920, second opening 1930, and third opening 1940 are preferably defined in outer tongue 1910 of article 1900. Generally, the sizes of openings 1920, 1930 and 1940 may be similar to the sizes of ball control elements 1820, 1830 and 1840 respectively. In this embodiment, first opening 1920 has first length 1960 and first width 1962 that are substantially similar to first length 1860 and first width 1862 of first ball control element 1820. Likewise, second opening 1930 can have second length 1970 and second width 1972 that are substantially similar to second length 1870 and second width 1872 of second ball control element 1830. Additionally, third opening 1940 can have third length 1980 and third width 1982 that are substantially similar to third length 1880 and third width 1882 of third ball control element 1840. This arrangement preferably allows for an interference fit, as discussed above, to prevent ball control elements 1820, 1830 and 1840 from slipping in and out of openings 1920, 1930 and 1940, respectively. Furthermore, as ball control elements 1820, 1830 and 1840 are attached to backing 1850, this arrangement allows insert 1810 to be fixed in place with respect to outer tongue 1910.
In some cases, the separation distance between adjacent ball control elements may also be substantially similar to the separation distance between adjacent openings on the outer tongue in order to facilitate the interference fit. In this embodiment, as seen in FIG. 5, first ball control element 1820 is separated from second ball control element 1830 by first distance 1866. Likewise, second ball control element 1830 is separated from third ball control element by second distance 1876. Additionally, first opening 1920 is separated from second opening 1930 by third distance 1956. Also, second opening 1930 is separated from third opening 1940 by fourth distance 1996. Preferably, distances 1866 and 1876 are substantially similar to distances 1956 and 1996, respectively. This arrangement generally increases the effectiveness of the interference fit between insert 1810 and outer tongue 1910 by providing a proper alignment between ball control elements 1820, 1830, and 1840 and openings 1920, 1930 and 1940.
In some embodiments, an insert may include additional provisions for being secured in place with respect to an outer tongue. In some cases, a ball control element may include a lip that is configured to extend over a portion of the outer tongue. In other cases, the ball control element may include additional portions that are configured to extend over a portion of the tongue. Using this arrangement, the insert may be fixed in place with respect to the outer tongue.

Referring to FIG. 12, first bridge 2450 can be received between first ball control element 2110 and second ball control element 2120. As first bridge 2450 is received between first ball control element 2110 and second ball control element 2120, first lip 2112 and second lip 2122 can be translated to allow first bridge 2450 past. In addition, first bridge 2450 can also flex or bend to fit between first lip 2112 and second lip 2122.
During a first position 2510 of insert 2100, first lip 2112 and second lip 2122 approach first bridge 2450. Following this, during a second position 2520 of insert 2100, first lip 2112 and second lip 2122 can bend downward to allow first bridge 2450 through. In some embodiments, first bridge 2450 may also bend or otherwise deform. In other embodiments, either or both of the first bridge 2450 or lips 2112 and 2122 can deform. By deforming, first bridge 2450 can fit between first lip 2112 and second lip 2122.
Following this, in a third position 2530 of insert 2100, first bridge 2450 is received between first lip 2112 and second lip 2122. At this point, first lip 2112 and second lip 2122 return to their previous positions. In some cases, first bridge 2450 may also return to an original shape.
