DETAILED DESCRIPTION OF THE DISCLOSURE

[0033] For simplicity, in the following detailed description and drawings only half a pair of shoes is illustrated and discussed, it being understood the other half of the pair of shoes is a mirror image.

[0034] Referring to FIGS. 1-4, there is illustrated a cleated soccer shoe 10 which includes an upper 12 which is attached to a midsole 14 which in turn is sandwiched between a cleat plate assembly 16 comprising a rigid heel plate 15 and rigid forefoot plate 17 as will be described in detail below, and an insole 18 which overlays the heel plate/forefoot cleat plate assembly 16. Midsole 14 in turn is sandwiched between the cleat plate assembly 16 and a base plate 20.

[0035] Referring in particular to FIGS. 3 and 4, the soccer shoe includes a depressed area 23 in the forward region of the insole 18, which corresponds to a depressed area 22 in the first region of the upper, i.e., foot supporting surface of the forefoot plate 17. Depressed areas 22 and 23 are located to underlie substantially only the first metatarsal head of the wearer, and includes a hollow or depression relative to the remainder of the forefoot region, of asymmetric shape with the lowest point of the hollow or depression skewed to the medial side of the center, as taught in prior U.S. Pat. No. 8,166,674, the contents of which are incorporated herein by reference.

[0036] The depressed area 22 extends below the bottom surface of the forefoot plate as a rounded dome like structure 50. Dome like structure 50 includes a center cleat 52 and a plurality of individual cleats 54 radially disposed around the center cleat 52. Also attached to the forefoot plate are a plurality of radially disposed cleats 56 configured from in front of the big toe of the wearer and along the outside lateral edge of the shoe. One or more additional radially disposed perimeter cleats 56A may be added along the outside medial edge of the shoe for additional stability.

[0037] The heel plate 15 includes a heel cup 60 in the form of a lop-sided generally round shaped depression 62 extending from the foot supporting surface, with its lowest region on its medial side. There is a corresponding lop-sided generally round shaped depression 63 in the insole 18. These two depressions serve to reduce pressure on the plantar facia of the wearer's foot as it travels from its attachment on the medial calcaneus to the proximal phalanges, i.e., as taught in our prior U.S. Pat. No. 10,702,008, the contents of which are incorporated herein by reference. Heel cup 60 typically is 1-4 mm deep at its lowest, preferably 2-3.5 mm deep, more preferably 2.5-3 mm deep. The depressed area 62 extends below the bottom surface of the forefoot plate as a rounded dome like structure 70. Dome like structure 70 includes a center cleat 72 located under the tuberosities of calcaneus and a plurality of individual cleats 74 radially disposed around the center cleat 72. Also attached to the heel plate are a plurality of radially disposed cleat elements 76.

[0038] The midsole 14 and based plate 20 are provided with holes 80, 82, 84, 86, 88 and 90 to accommodate the rounded depression structures 50, 62 and cleats 56, 76 extending from the bottom of heel plate 15 and forefoot plate 17.

[0039] Heel plate 15 and forefoot plate 17 are connected by a flexible bridge member 92 which provides flexibility permitting the heel plate and the forefoot plate to move independently of one another during activity.

[0040] A feature and advantage of the domed cleat of the present disclosure, with studs arranged around center of the dome is that the structure creates a cleat that will resist lateral, linear motion, and reduce resistance to rotary motion.

[0041] Also in a preferred embodiment, the cleat plate may have oval cleats arranged with the short axis in line with the center of rotation so that the first cleat “cuts” a path for the subsequent cleats, to reduce resistance to rotary motion about the center point of the dome cleat.

[0042] Moreover, the domed cleat is located directly under the first metatarsal head, and the tuberosities of the calcaneus, providing centers of rotation around both the ball of the foot and the calcaneus.

[0043] Additionally, the foot supporting surface of the ball of foot dome has lowers the ball of foot into the cleat plate, reducing leverage of lateral forces that would tend to cause the foot to invert.

[0044] Additionally, foot supporting surface of the calcaneus dome has the cradle surface that lowers the heel into the cleat plate, reducing the leverage of lateral forces that would tend to cause the foot to invert.

[0045] Also, the cleat plate is separated into two sections connected by a more flexible bridge that will allow pitch and roll while resisting yaw.

[0046] Various changes may be made in the foregoing disclosure without departing from the spirit and scope thereof. For example, while the disclosure has been made particularly with respect to soccer shoes, the disclosure advantageously also may beneficially be used with other cleated footwear, including, for example those used in baseball, football, and track shoes advantageously may particularly benefit from our technology. Also, sports footwear such as golf shoes, and track shoes for shot put, discus, javelin, and the like in which the wearer imposes unidirectional or asymmetric rotational movement advantageously may benefit from our technology by fashioning the left and right shoes to accommodate such movements. For example, as in the case of golf, the wearer's feet pronate and supinate in opposite directions during a swing. Thus, as illustrated in FIG. 5 the left and right shoes are fashioned to accommodate asymmetric rotational movement and would be different for left and right handed players. Also, as illustrated in FIGS. 6 and 7, the right shoe could be mirrored to create cleats that focus rotation around the balls of the feet, and likewise, the left shoe could be mirrored to focus rotation around the heels of the feet. Thus, for a right hand player the right shoe 80 may have a central cleat 50 configured to lie directly under the first metatarsal head of the wearer, and all additional cleats 56 on that shoe are radially arranged around the central cleat 50 of the right shoe, and with the left shoe 82 having a central cleat 70 configured to lie directly underlie the calcaneus bone of the wearer, and all additional cleats 56 on that shoe are radially arranged around the central cleat 70 of the left shoe 82. And, for a left handed player, the cleat patterns on the right and left shoes would be reversed. Also, by forming the cleat plate with a separate heel plate and forefoot plate, the shoe could be custom fitted to individuals depending on their ball of foot length by adjusting the length of bridge member 92, and the co-located holes 80 and 86 in midsole 14 and baseplate 20 and the co-located depressions 22 and 23 and the co-located cleated dome 50. The cleat plate and insole also may be 3D printed to custom fit the shoes to the wearer.
