DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be used, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
The present disclosure pertains, inter alia, to footwear, such as athletic shoes. Some example embodiments according to the present disclosure may comprise soccer shoes, which may include a substantially straight last, a wide forefoot, and/or one or more cleats which may provide generally even force distribution for the foot.
The present disclosure contemplates that the term “last” may refer to the shape of a shoe and/or to a form, or mold, around which a shoe may be constructed. Shoes may be described as having a “straight last,” “semi-curved last,” or a “curved last.” Generally, these terms relate to the shape of an imaginary line that extends through the center of the heel of the shoe and through the center of the toe area of the shoe. For example, in a straight lasted shoe, this imaginary line may be substantially straight. In a curved last shoe, this imaginary line may be substantially curved, such as inwardly curved.
The present disclosure contemplates that some conventional soccer shoes may include a curved or semi-curved last and a generally narrow forefoot. Such conventional soccer shoes may compress the wearer's forefoot into the toe box, which may cause an unnatural fit in the shoe.
The present disclosure contemplates that gross foot motion may be based upon pronation and supination. During pronation, the foot may be collapsed to absorb shock and may act as a mobile adaptor to the terrain to which it is moving upon. During the transition from pronation to supination, the foot may become a propulsive and rigid lever for the body to move efficiently.
The present disclosure contemplates that characteristics of pronation may include forefoot dorsiflexion, rear foot plantar flexion, ankle dorsiflexion in the sagittal plane, forefoot inversion and rear foot eversion in the frontal plane, and forefoot abduction and rear foot adduction in the transverse plane.
The present disclosure contemplates that characteristics of supination may include forefoot plantar flexion, rear foot dorsiflexion, ankle plantar flexion in the sagittal plane, forefoot eversion and rear foot inversion in the frontal plane, and forefoot adduction and rear foot abduction in the transverse plane.
The present disclosure contemplates that transformation from pronation to supination may be necessary and timing of the transition may play a major role. If any joint is forced into a position prematurely by an ill-fitting shoe, the foot cannot go through its natural motion because timing is thrown off and undue stress is placed on the foot but also effects motion and dissipation of forces all the way through the head. For example, the toes are forced too tight into the toe box causing the fourth and fifth phalanges and metatarsals to become adducted. When the forefoot should be abducted during pronation, it is supinated and thus throws off timing. This may result in undue stress to the fifth metatarsal and cause a stress fracture, a common injury in soccer.
The present disclosure contemplates that inversion sprains of the ankle make up a high percentage of injuries in soccer. A forefoot is forced into adduction when it should be abducted encourages a player to compensate upon landing because they cannot land with a collapsed and mobile foot. Exacerbating the problem, the forefoot last of some soccer shoes may be more narrow than the foot itself. This may cause a problem for when the player is weight bearing, and even more so when a player lands from a high jump. Because the last is not proportional to the foot, the forefoot is not allowed to splay out and properly absorb shock. This provides for an increased possibility of injury. Furthermore, it stops the foot from producing optimal force due to lack of contact with the ground. Overall, the shape of some soccer shoes may allow for a lack of overall performance and increased risk of injury.
Some example shoe systems according to the present disclosure may include several features assembled together to provide a high-performance and safe soccer cleat. The wide forefoot, straight last, unique cleat design and/or short lacing system may work together to minimize injury and maximize performance.
FIG. 1 shows a side view of an example shoe 10. The upper 15 is attached to the sole 60. The upper comprises a lacing system 40 having a lacing system length 40A generally aligned with the interior length 10A of the shoe 10. The lacing system length 40A may extend less than about 0.35 times the interior length 10A. The lacing system may extend from a cuff 20 of the shoe into a portion of the upper 15. The short lace system may deepen the toe box 50 (also referred to as the forefoot portion), increasing the surface area on the upper 15. This may improve a player's contact with a soccer ball. This lacing design may also help provide optimal power when the foot pushes off the ground from any angle. It may prevent the shoe material from bunching up and causing the toe box 50 to tighten, thus maintaining the foot in its proper shape. In some example embodiments, the lacing system length 40A may extend less than about 0.3 times the interior length 10A. In some example embodiments, the lacing system length 40A may extend less than about 0.25 times the interior length 10A.
The shoe 10 may include a sole 60 comprising an outsole 60A (see FIG. 3). The outsole 60A may comprise a plurality of cleats 65A-65C and 65J-65K. The upper 15 and the sole 60 may at least partially define an interior 10B (see FIG. 2), which may be configured to house a wearer's foot. Sole 60 may extend substantially from a heel portion 55 to the forefoot portion 50.
FIG. 2 shows the top view of an example shoe 10. The cuff 20 provides an opening allowing the wearer to place a foot in the shoe. The relation between the lacing system 40 and the forefoot portion 50 is depicted. The ample width 50A of the forefoot 50, or toebox, is also discernable.
Heel portion 55 may have a heel portion maximum width 55A. The forefoot portion 50 maximum width 50A may be at least about 1.5. times the heel portion 55 maximum width 55A. The toe box 50 is in the mid-front portion of the forefoot. The shoe system may incorporate a wide toe box 50 which may allow the foot to lie naturally in the shoe. The wide toe box 50 may provide a large surface area to contact a ball and increase its force off the ground. The wide toe box 50 may offer increased surface area for a player to contact a soccer ball for a more accurate ball strike. In some example embodiments, the forefoot portion 50 maximum width 50A may be at least about 1.7 times the heel portion 55 maximum width 55A. In some example embodiments, the forefoot portion 50 maximum width 50A may be at least about 1.9 times the heel portion 55 maximum width 55A.
The lacing system 40 may include any known type of lacing system, including a plurality of eyelets and a cord threaded through the plurality of eyelets, a plurality of loops and the cord threaded through the plurality of loops, and a plurality of hooks and the cord threaded through the plurality of hooks.
FIG. 3 shows a bottom view of an example shoe 10. Outsole 60A may include one or more cleats 65A, 65B, 65C, 65D, 65E, 65F, 65G, 65H, 65I, 65J, 65K, 65L, 65M, 65N, 650. This embodiment could be used for soccer play. An even cleat design may allow for the foot to lay at an even distance from the ground from toe to heel, allowing a greater push-off force from the ground in any direction. Referring to FIG. 7, an individual cleat 65 may be generally trapezoid shaped, with two legs 65(1A), 65(1B) of about the same length, a generally long base 65(2), and a generally short base 65(3). Short base 65(3) may be concave towards the long base 65(2).
Referring back to FIG. 3, an exemplary embodiment may include two clusters of cleats 65A-65O. A first cluster of cleats 65A-65I may be disposed on a forefoot portion 50B of the outsole 60A and a second cluster of cleats 65J-65O may be disposed on a heel portion 55B of the outsole 60A. A portion of the outsole 60A between the forefoot portion 50B and the heel portion 55B may be substantially devoid of cleats. Both clusters of cleats 65A-65O may be arranged so the cleats 65D-65F, 65N-65O on the outer side of the shoe 10 correspond to the cleats 65A-65C, 65J-K on the inner side of the shoe 10 in number and are mirrored in orientation. Two rows of cleats 65D-65F, 65N-65O and 65A-65C, 65J-K may be placed near the edge of the shoe 10 and may be oriented so their respective straight bases 65(2) (FIG. 7) are turned toward the edge of the shoe 10, and the concave bases 65(3) face towards the center of the shoe 10. A third row of cleats 65G-65I, and 65N may be arranged perpendicularly crossing a longitudinal portion of the shoe, with respective concave bases 65(3) facing the mid-sole of the shoe 10.
FIG. 4 shows an example sole 60 of a shoe 10. The forefoot portion 50B and the heel portion 55B may be substantially linearly arranged to provide a generally straight last. The generally straight last is depicted by providing an imaginary line 70 down the center of the sole 60. The straight last gives general symmetry to the shoe relative from the line 70, generally from the center of the heel and the center of the toes. The shoe contemplates a generally straight, neutral last which does not attempt to add curvatures in a foot which may not be present in a particular foot. The straight last may increase safety because may allow the foot lay in its natural position.
The characteristics and features of the example shoes described herein can be adapted to create other types of shoes. FIG. 5 shows an alternate example shoe 11, in a bottom view. For example, by replacing the smaller cleats discussed above with generally evenly distributed and generally flat, pad- like cleats 165A, 165B, 165C, 165D, 165E, 165F, 165G, 165H, 165I, 165J, 165K, 165L, 165M, 165N on sole 160, this embodiment can be used as a running shoe 11. Padding 75A and 75B can be added for this embodiment. The padding 75A, 75B may extend beyond the rest of the sole 60 by no more than a few millimeters. Similar adaptation methods may be used for all types of sports shoes and casual shoes.
FIG. 6 shows sole 160 of the example embodiment illustrated in FIG. 5, in a bottom view, and without the padding 75A, 75B.
Example shoes according to the present disclosure may be made through a combination of molding and fabrication. The shoe outsole 60 and cleats 65A-65O can be molded. The shoe upper 15 and lacing system 40 can be fabricated. The molded cleats and sole 60 may be connected to the other components by any known cobbling methods, such as by sewing, gluing, or other methods. A person uses example shoes 10 by placing their foot in the shoe and tightening the laces to their desired comfort level.
While example embodiments have been set forth above for the purpose of disclosure, modifications of the disclosed embodiments as well as other embodiments thereof may occur to those skilled in the art. Accordingly, it is to be understood that the disclosure is not limited to the above precise embodiments and that changes may be made without departing from the scope. Likewise, it is to be understood that it is not necessary to meet any or all of the stated advantages or objects disclosed herein to fall within the scope of the disclosure, since inherent and/or unforeseen advantages may exist even though they may not have been explicitly discussed herein.
