Definitions

  • the present invention relates to athletic shoes, and in particular, to a cleated athletic shoe wherein the outsole includes a structure which prevents downward flexing of the ball area of the outsole.
  • the modern athletic shoe is a combination of many elements which have specific functions, all of which must work together for the support and protection of the foot during an athletic event.
  • the design of an athletic shoe has become a highly refined science. No longer do athletes and participants in sports events use a pair of "sneakers” for all sports.
  • Athletic shoes today are as varied in design and purpose as are the rules for the sports in which the shoes are worn. Tennis shoes, raequetball shoes, basketball shoes, running shoes, baseball shoes, football shoes, soccer shoes, weight lifting shoes, etc., are all designed to be used in very specific, and very different, ways. They are also designed to provide a unique and specific combination of traction, support, and protection to enhance athletic performance.
  • shoes designed for specific sports they are also designed to meet the specific characteristics of the user. For example, athletic shoes are designed differently for heavier persons than for lighter persons. Some shoes are designed to correct physical problems, such as over-pronation, while others include devices, such as ankle supports, to prevent physical problems from developing.
  • One type of athletic shoe is a cleated athletic shoe having a plurality of relatively large cleats located in the toe, ball and heel areas of the outsole.
  • the cleats are used to increase traction in field sports wherein direction is changed frequently or large amounts of power must rapidly be passed from the foot and leg to the remainder of the body, such as in football and soccer.
  • the cleats may be removable from the base of the outsole or may be formed integral with it.
  • the cleats typically have an outer surface formed of a hard rubber or thermoplastic material. Examples of prior art cleated athletic shoes are found in U.S. Patent No. 2,258,734 issued to Brady on October 14, 1941 and U.S. Patent No. 2,330,458 issued to Tubbs on September 28, 1943.
  • the cleats are removably attached to thin metal or plastic plates within the outsole.
  • the shank area of the outsole has a plurality of slits rendering it highly flexible in one direction of bending, without noticeably affecting its flexibility in the other direction.
  • the Tubbs patent also discloses removable cleats attached to metal plates embedded in the outsole.
  • the cleats in the heel area of the shoe disclosed in the Tubbs patent are arranged so that the cleat on the lateral side of the outsole is forward of the cleat on the medial side of the outsole.
  • cleated athletic shoes which are specifically designed for soccer, typically have an outsole formed of a thermoplastic material such as nylon or polyurethane wherein cleats are either integrally or removably attached to reinforced areas of the outsole.
  • An upper of leather or a synthetic material such as nylon or vinyl is attached to the thermoplastic outsole.
  • the outsole typically has a built in toe spring, i.e., an upward bend of the outsole in the ball and toe area of the foot, which aids the athlete's locomotion.
  • Turf toe is used as a generic term to refer to numerous types of injuries to an athlete's toes. Turf toe can manifest itself in a number of ways such as inflamation or pain in the toes, stress fractures in the bones of the toe or tendonitus in the ligaments of the toes. Just as turf toe can manifest itself in numerous types of injuries, turf toe also can result from numerous causes. For example, in football, it is believed that turf toe is caused by the high stress which football linemen place on their feet, particularly their toes, as they rapidly move upward from a down lineman's stance.
  • the present invention is directed to an outsole for use in an athletic shoe, and to an athletic shoe per se.
  • the outsole includes an outsole layer formed of a material which extends along the bottom of the shoe and has a lower side which faces the ground and an upper side which is attached to the upper.
  • the layer of material is flexible about its major surface.
  • a means is connected to the outsole layer for preventing the downward flexing motion of the front end of the outsole layer while permitting the upward flexing thereof.
  • the present invention is directed to a cleated athletic shoe wherein a sole is attached to an upper.
  • the sole includes an outsole layer which has a heel area, an arch area, a ball area and a toe area, corresponding to the general areas of the foot; and is formed of a thermoplastic material flexible about its major surface.
  • the ball and toe areas of the outsole layer are bent upward with respect to the arch and heel areas in the normal unstressed condition of the shoe, i.e., have a built in spring.
  • a plurality of abutting elements extend downward from the outsole layer and function as a means for preventing the downward bending of the ball and toe area of the outsole layer below the upward bent, unstressed position, while permitting further upward bending motion.
  • the abutting elements include a forwardmost element, a rearwardmost element and plurality of intermediate elements located between the forwardmost and rearwardmost elements.
  • a transverse slot extends between adjacent abutting elements to separate the adjacent elements from one another and to form a contact surface on each abutting element which extends upward from the lower surface of each element.
  • Facing contact surfaces of adjacent abutting elements are in contact with one another in the normal unstressed position of the outsole, and the abutting elements have a thickness and hardness sufficient to prevent the downward bending motion of the outsole layer from its normal unstressed position.
  • a plurality of cleats extend downward from the outsole layer.
  • the cleats include a first pair of cleats connected to the forwardmost element, a second pair of cleats connected to the rearwardmost element and a third pair of cleats in the heel area.
  • a reinforcement element extends downward from and transversely across the heel area of the outsole layer.
  • the heel reinforcement element extends at an angle backward from the lateral side of the outsole to its medial side.
  • the pair of cleats in the heel area are connected to the heel reinforcement element.
  • Hyperextension of the toes of a soccer athletic during ball kicking motions is prevented because the abutting elements extending downward from the outsole layer do not permit the ball and toe area of outsole layer to flex downward from its upward bent toe spring position. While hyperextension is prevented, normal upward bending motion of the ball and toe of the foot is premitted because of the transverse slits between adjacent toe abutting elements.
  • the use of the angled heel reinforcement enhances the stability of the soccer athlete, particularly during changes of direction foot motions. In change of direction of foot motions, an athlete tipically abducts, i.e., points the toes of the foot outward. In the abducted position the angled heel reinforcement element aligns parallel with the forward position of the body, thereby enhancing the stability of the athlete's foot plant.
  • Shoe 10 includes a shoe upper 12 to which an outsole 14 is attached.
  • Upper 12 can be made of any suitable material such as nylon, vinyl or leather.
  • upper 12 is made of a fine-grade leather lined with a synthetic material.
  • Upper 12 includes a conventional counter 16 and a reinforced throat 18 provided with laceholes 20.
  • Outsole 14 includes an outsole layer 22 formed of a flexible thermoplastic material.
  • the thermoplastic material of outsole layer 22 is nylon having a hardness of approximately 80-85 durometer on the Shore A scale and a thickness between approximately 100 and 275 thousandths of an ineh.
  • Outsole layer 22 is flexible about its major surface extending along the base of sole 1 4 so as to permit normal bending motion of the foot during walking and running.
  • Outsole layer 22 has a bottom side which faces the ground and a top side which is attached to an insole and the upper by any suitable means such as gluing.
  • outsole layer 22 can also be riveted to the insole and upper by rivets 24 in the toe and heel area.
  • Outsole layer 22 extends along the entire bottom of shoe 10 and, for reference purposes, can be divided into a heel area rearward of line L l , an arch area between lines L 1 and L 2 , a ball area between lines L 2 and L 3 , and a toe area forward of line L 3 .
  • Lines L 1 , L 2 and L 3 illustrate approximate division lines of the heel area 26, arch area 28, ball area 30 and toe area 32 which refer to the heel, arch, ball and toe portions of a wearer's foot.
  • outsole layer 22 has a built-in toe spring, i.e., an upward bend of the ball and toe area 30, 32 of outsole 22, illustrated as a distance T, above the ground G.
  • the amount of toe spring can be varied, and is incorporated into outsole 22 to assist the athlete in attaining a ready position on the ball of the foot.
  • Outsole 22 also includes a plurality of corrugations 34 in ball area 30 to increase the flexibility of outsole layer 22 in this area.
  • Outsole layer 22 is shown in Figure 1 in its normal rest position wherein outsole layer is unstressed and an athlete would be merely standing at rest.
  • a structure is provided for preventing the outsole layer 22 from bending further downward from its unstressed position, which in the preferred embodiment is an upwardly toe spring curved position, such as illustrated in Figure 1.
  • This structure includes a plurality of abutting elements extending downward from the outsole layer 22 in ball area 30.
  • the abutting elements include a forwardmost element 34, a rearwardmost element 36 and a plurality of intermediate elements 38.
  • the elements 34, 36 and 38 are separated from one another by slots 40. Slots 40 extend upward from the lower surface of elements 34, 36 and 38 to define contact surfaces 42 on the respective elements. Slots 40 are angled forward from the lateral side to the medial side of outer layer 22. In the normal unstressed position of outsole layer 22, contact surfaces 42 are in complete contact with one another as shown in Figures 2, 3 and 4. As the ball and toe area of outsole layer 22 are bent further upward, as during normal running and walking motions, the contact surfaces 42 move away from one another, as shown in Figure 3a.
  • elements 34, 36 and 38 are made of a harder material than outsole layer 22.
  • forwardmost and rearwardmost elements 34, 36 be harder than the intermediate elements 38.
  • forwardmost and rearwardmost elements 34, 36 can be formed of a densely packed fiberglass reinforced nylon having a Shore A durometer hardness of about 95, while intermediate elements 38 are formed of a less densely packed fiberglass reinforced nylon having a Shore A durometer of approximately 90.
  • element 34, 36 and 38 formed of the specified hardness, a thickness of aproximately 80 thousandths of an inch for the element 34, 36 and 38 has been found sufficient.
  • other materials, as well as thicknesses and hardnesses of material can be used, as long as the function of preventing the downward flexing of the ball and toe area of the outsole is preserved.
  • the forwardmost and rearwardmost elements 34, 36 extend transversely across substantially the entire width of outsole layer 22, while intermediate elements 38 are formed in transversely aligned pairs along the medial and lateral sides of outsole layer 22.
  • Corrugations 35 are located within the area bounded by the inside edges of intermediate elements 38 and the forwardmost and rearwardmost elements 34, 36.
  • the area of corrugations 35 function as shock attenuation area allowing a limited degree of downward flexing motion to cushion the foot.
  • Additional elements or bars 44 extend downward from outsole layer 22 in the rear portion of ball area 30 to further enhance the transverse rigidity and stability of outsole layer 22.
  • additional elements or ridges 46 extend downward and across at least a portion of the transverse width of outsole layer 22 along the lateral side of arch area 28 to provide further rigidity to outsole layer 22 without unduly restricting its flexibility.
  • Elements 44, 46 are also preferably formed of a harder material than outsole layer 22, preferably of intermediate hardness such as an intermediate elements 38.
  • a heel reinforcement element 48 extends downward from outsole layer 22 and across substantially its entire width in the heel area 26.
  • a medial arch support element 50 also extends downwardly from outsole layer 22, and extends forward from heel reinforcement element 48 along the medial side of outsole layer 22 and arch area 28.
  • Both heel reinforcement element 48 and medial arch support 50 are preferably formed of a hard material, such as the material of elements 34, 36.
  • Outsole layer 22 can also be formed thicker in an area substantially coextensive with elements 48, 50, as seen in Figure 6, for example, to a thickness in its upper range of thickness, 275 thousandths of an inch.
  • Heel reinforcement element 48 extends at a rearwardly sloped angle from the lateral side to the medial side of the outsole layer 22. This disposition of heel reinforcement element 48 places it in parallel alignment with the body of an athlete during typical change of direction of motion when the feet of the athlete are normally in an abducted position. Lateral stability during motion changes is thus enhanced.
  • Medial arch support element tapers in width from its maximum width of approximately one-half the width of outsole layer at its rearward section, where it joins with heel reinforcement element 48, to its forwardmost end adjacent the forward end of arch area 28 and, thus, follows the general shape of the arch of a foot.
  • elements 34, 36, 38, 44, 46, 48 and 50 are preferably formed of three different materials of different hardnesses, it is preferable to form these elements integral with outsole layer 22. In some cases, it may be desirable to form all the elements and the outsole layer of a single material, however, the function of the elements should be preserved.
  • a first pair of cleats 52 are connected to forwardmost element 34 in a conventional manner, such as by threading engagement or integral molding.
  • a second pair of cleats 54 are attached to the rearwardmost abutting element 36; and a third pair of cleats 56 are connected to the heel reinforcement element 48.
