    Description

    BACKGROUND



    [0001] The present invention relates generally to an article of footwear and, more particularly, to a sports shoe with cleats.

    [0002] Articles of footwear having cleats have previously been proposed. While conventional cleats generally help give sports shoes more grip, the cleats do not necessarily optimize propulsion while stabilizing the wearer's foot. Moreover, the cleats do not always provide stability and responsiveness while also moderating stud pressure. It would be advantageous for a sports shoe to have cleats that optimize propulsion during the first step of sprinting and provide stability and responsiveness while also moderating stud pressure during quick directional changes.

    [0003] US 5 461 801 A relates to a cleated athletic shoe having a crisscross arch reinforcement extending between selected cleats on the sole of the shoe. JP 2002 306207 A discloses an article of foortwear with the features of the preamble of claim 1.

    SUMMARY



    [0004] An article of footwear with a base plate having a structure and studs is disclosed. The structure may moderate stud pressure and enhance support during the first step of sprinting, quick directional changes, and backward movement.

    [0005] According to the invention, the article of footwear includes features disclosed in claim 1.

    [0006] Preferred embodiments of the invention are defined in dependent claims 2-7.

    DETAILED DESCRIPTION



    [0008] An article of footwear with a base plate having a structure and studs is disclosed. FIGS. 1-7 illustrate an exemplary embodiment of a base plate 102. Base plate 102 may be associated with an article of footwear 100. The following detailed description discusses an exemplary embodiment in the form of a soccer shoe, but it should be noted that the present concept may be associated with any article of footwear, including, but not limited to, baseball shoes, rugby shoes, and football shoes. Article of footwear 100 shown in FIG. 1 may be intended to be used with a left foot. However, it should be understood that the following discussion may apply to a mirror image of article of footwear 100 that may be intended to be used with a right foot.

    [0009] In some embodiments, base plate 102 may be associated with an upper 104. FIGS. 1 and 3 show upper 104 in phantom lines. FIG. 1 is an isometric view of article of footwear 100 from a lateral side. FIG. 3 is an isometric view of article of footwear 100 from a medial side. Upper 104 may be attached to base plate 102 by any known mechanism or method. For example, upper 104 may be stitched to base plate 102 or upper 104 may be glued to base plate 102. Upper 104 may be configured to receive a foot. The exemplary embodiment shows a generic design for upper 104. In some embodiments, upper 104 may include another type of design.

    [0010] Base plate 102 and upper 104 may be made from materials known in the art for making articles of footwear. For example, base plate 102 may be made from elastomers, siloxanes, natural rubber, synthetic rubbers, aluminum, steel, natural leather, synthetic leather, plastics, or thermoplastics. In another example, upper 104 may be made from nylon, natural leather, synthetic leather, natural rubber, or synthetic rubber.

    [0011] For clarity, base plate 102 is shown in isolation in FIGS. 2 and 4-7. FIG. 2 is a side view of base plate 102 from the lateral side. FIG. 4 is a side view of base plate 102 from the medial side. Base plate 102 may include a top surface 206 and a bottom surface 208. Base plate 102 may have a longitudinal axis A extending through the length of base plate 102 (FIG. 5). Base plate 102 may be configured to be attached to upper 104. Base plate 102 may also be configured to be attached to a midsole or an insole of an article of footwear. Top surface 206 may be configured to contact the midsole or the insole. Base plate 102 may include a forefoot region 107 disposed proximate a wearer's forefoot. Base plate 102 may include a heel region 111 disposed proximate a wearer's heel and opposite the forefoot region 107. Base plate 102 may include a midfoot region 109 disposed between forefoot region 107 and heel region 111. Base plate 102 may include a medial edge 112 and a lateral edge 116 opposite medial edge 112. The center region of base plate 102 may include the area proximate the halfway point between medial edge 112 and lateral edge 116. Base plate 102 may include a forward edge 134 and a rearward edge 142 disposed opposite forward edge 134.

    [0012] Bottom surface 108 may be configured to contact a playing surface. For example, bottom surface 108 may be configured to contact grass, synthetic turf, dirt, or sand. Base plate 102 may include provisions for increasing traction with such a playing surface. For example, such provisions may include studs. The arrangement of studs may enhance traction for a wearer during cutting, turning, stopping, accelerating, and lateral movement. The studs are discussed in more detail below.

    [0013] Base plate 102 may include components other than studs that contact a playing surface and increase traction. In some embodiments, base plate 102 may include traction elements that are smaller than studs. For example, base plate 102 may include teeth 168. Traction elements on base plate 102 may increase control for wearer when maneuvering forward on a surface by engaging surface. Additionally, traction elements may also increase the wearer's stability when making lateral movements by digging into playing surface. In some embodiments, traction elements may be molded into base plate 102. In some embodiments, base plate 102 may be configured to receive removable traction elements. As shown in FIGS. 1-6, teeth 168 may be disposed on forefoot region 107 along forward edge 110.

    [0014] Base plate 102 may be a carrier plate for a structure 118. Structure 118 may act as a frame, or brace, for base plate 102. Structure 118 may be made of a stiffer, more responsive material than base plate 102 and may, thus, affect the movement of base plate 102. Structure 118 may be made from materials known in the art for making articles of footwear. For example, in some embodiments, base plate 102 may be made of renewable materials, such as Nylon 11, a polyamide bioplastic derived from vegetables. Structure 118 may moderate the pressure of studs disposed on base plate 102. In some embodiments, base plate 102 may be configured to receive removable studs. In other embodiments, base plate 102 may be associated with molded studs. For example, base plate 102 may be configured to receive molded studs. In another example, base plate 102 may include studs integrally formed with base plate 102 through molding. As shown in FIGS. 1 and 3, structure 118 may be raised with respect to base plate 102. In other embodiments, some or all of structure 118 may be flush with base plate 102.

    [0015] The studs may be made from materials known in the art for making articles of footwear. For example, the studs may be made from elastomers, siloxanes, natural rubber, synthetic rubbers, aluminum, steel, natural leather, synthetic leather, plastics, or thermoplastics. In some embodiments, the studs may be made of the same materials. In other embodiments, the studs may be made of various materials. For example, one stud may be made of aluminum while another stud is made of a thermoplastic material. In some embodiments, the studs may have the same shape. In other embodiments, the stud may have different shapes. For example, the exemplary embodiment shown in FIGS. 1-7 illustrates studs of different shapes. In some embodiments, the studs may have the same height, width, and/or thickness. In other embodiments, the studs may have different heights, different widths, and/or different thicknesses.

    [0016] In some embodiments, structure 118 may be disposed on the forefoot region 107 of base plate 102. In other embodiments structure 118 may be disposed on the heel region 111 of base plate 102. In some embodiments, structure 118 may be disposed on the midfoot region 109 of base plate 102. In yet other embodiments, structure 118 may be disposed on two or more of forefoot region 107, midfoot region, and heel region 111 of base plate 102.

    [0017] In some embodiments, base plate 102 may be configured to receive structure 118. In some embodiments, base plate 102 may include a contoured surface providing recesses into which structure 118 may be received. In some embodiments, a portion of structure 118 disposed on forefoot region 107 may include a first medial forefoot pad 120, a second medial forefoot pad 122, a first lateral forefoot pad 124, a second lateral forefoot pad, a medial forefoot bar 128 and a lateral forefoot bar 130. In some embodiments, a portion of structure 118 disposed between forefoot region 107 and rearward edge 114 may include a first diagonal rib 146, a second diagonal rib 148, a medial midfoot bar 150, a lateral midfoot bar 152, a medial heel pad 154, a first lateral heel pad 156, and a second lateral heel pad 158.

    [0020] Second medial forefoot pad 122 may be disposed on forefoot region 107 proximate midfoot region 109 and medial edge 112. Second lateral forefoot pad 126 may be disposed on forefoot region 107 proximate midfoot region 109 and lateral edge 116. Second medial forefoot pad 122 may be connected to second lateral forefoot pad 126. In some embodiments, second medial forefoot pad 122 may taper in the direction of lateral edge 116. In some embodiment, second medial forefoot pad 122 may taper in the direction of second lateral forefoot pad 126. In some embodiments, second lateral forefoot pad 126 may taper in the direction of medial edge 112. In some embodiment, second lateral forefoot pad 126 may taper in the direction of second medial forefoot pad 122. The size, shape, and/or location of second medial forefoot pad 122 and/or second lateral forefoot pad 126 may be selected based on a variety of factors. For example, the size, shape, and/or location of second medial forefoot pad 122 may be selected to provide a certain degree of stiffness in base plate 102 and/or to provide a certain degree of pressure. Second medial forefoot pad 122 and second lateral forefoot pad 126 may taper to the point where second medial forefoot pad 122 and second lateral forefoot pad 126 connect such that base plate 102 maintains flexibility at this point. Such a configuration may provide side-to-side flexibility.

    [0021] In some embodiments, a second medial forefoot stud 134 may be disposed on second medial forefoot pad 122. In some embodiments, a second lateral forefoot stud 138 may be disposed on second lateral forefoot pad 126. In some embodiments, a third lateral forefoot stud 140 may optionally be disposed on second lateral forefoot pad 126. The size, shape, and/or location of second medial forefoot stud 134, second lateral forefoot stud 138, and/or third lateral forefoot stud 140 may be selected based on a variety of factors. For example, the size, shape, and/or location of second medial forefoot stud 134 may be selected to provide a certain amount of penetration during toe-off. In another example, the size, shape, and/or location of second lateral forefoot stud 138 and third lateral forefoot stud 140 may be selected to provide stability and to enhance traction on the lateral side of the wearer's foot during lateral movement. In some embodiments, second medial forefoot stud 134 may include an aperture 133, second lateral forefoot stud 138 may include an aperture 137, and/or third lateral forefoot stud 140 may include an aperture 139. Aperture 133, aperture 137, and/or aperture 139 may include any of the features disclosed in Auger et al., U.S. patent publication number 2009/0235558, entitled Cleat Member for Article of Footwear, published on September 24, 2009. In some embodiments, second lateral forefoot stud 138 and third lateral forefoot stud 140 may be aligned with each other a direction that is substantially parallel to lateral midfoot bar 152. In some embodiments, second medial forefoot pad 122 may have a surface area that is larger than a base of second medial forefoot stud 134. In some embodiments, the size, shape, and/or location of the base of second medial forefoot stud 134 may be selected based on the size, shape, and location of second medial forefoot pad 122. Second medial forefoot stud 134 may taper from the base to a tip to provide stability in the base and enhanced penetration in the tip. Second medial forefoot stud 134 may have a circular tip.

    [0022] As shown in the drawings, in some embodiments, second lateral forefoot stud 138 and third lateral forefoot stud 140 may be joined at their bases such that the two studs share a single base.

Second lateral forefoot stud 138 may taper from the base to a tip to provide stability in the base and enhanced penetration in the tip. Second lateral forefoot stud 138 may have a circular tip. Third lateral forefoot stud 140 may taper from the base to a tip to provide stability in the base and enhanced penetration in the tip. Third lateral forefoot stud 140 may have a circular tip. In some embodiments, second lateral forefoot stud 138 and third lateral forefoot stud 140 may each have their own individual base. In such embodiments, the individual bases may be connected to one another.

    [0023] In some embodiments, a first center stud 142 may be disposed on the center region of forefoot region 107. In some embodiments, first center stud 142 may be disposed on the point where first medial forefoot pad 120 and first lateral forefoot pad 124 connect. First center stud 142 may provide traction during forward movement. In some embodiments, the size, shape, and/or location of the base of first center stud 142 may be selected based on a variety of factors. For example, the size, shape, and/or location of the base of first center stud 142 may be selected based on the size of the point where first medial forefoot pad 120 and first lateral forefoot pad 124 connect. The size of the base of first center stud 142 may be the same as the surface area of the point. The width of first center stud 142 may taper from the base to a tip to provide stability in the base and enhanced penetration in the tip. First center stud 142 may have a constant thickness that is thin relative to the width of first center stud 142.

    [0024] In some embodiments, a second center stud 144 may be disposed on the center region of forefoot region 107. In some embodiments, second center stud 144 may be disposed on the point where second medial forefoot pad 122 and second lateral forefoot pad 126 connect. In some embodiments, second center stud 144 may substantially align with first center stud 142 along the center region of base plate 102. In some embodiments, second center stud 144 may be slightly offset from first center stud 142 along the center region of base plate 102. Second center stud 144 may provide traction during forward movement. In some embodiments, the size, shape, and/or location of the base of second center stud 144 may be selected based on a variety of factors. For example, the size, shape, and/or location of the base of second center stud 144 may be selected based on the size of the point where second medial forefoot pad 122 and second lateral forefoot pad 126 connect. The size of the base of second center stud 144 may be the same as the surface area of the point. The width of second center stud 144 may taper from the base to a tip to provide stability in the base and enhanced penetration in the tip. In some embodiments, second center stud 144 may have a constant thickness that is thin relative to the width of second center stud 144.

    [0025] Medial forefoot bar 128 may extend from first medial forefoot pad 120 to second medial forefoot pad 122 such that medial forefoot bar 128 connects first medial forefoot pad 120 to second medial forefoot pad 122. Medial forefoot bar 128 may be disposed proximate medial edge 112. Medial forefoot bar 128 may extend in a direction that is substantially parallel to the portion of medial edge 112 that medial forefoot bar 128 is proximate. Medial forefoot bar 128 may extend in a direction that is substantially parallel to longitudinal axis A. In some embodiments, medial forefoot bar 128 may be substantially straight. As shown in FIG. 5, in some embodiments, medial forefoot bar 128 may be slightly curved to follow the curvature of medial edge 112. The size, shape, and/or location of medial forefoot bar 128 may be selected based on a variety of factors. For example, the size, shape, and/or location of medial forefoot bar 128 may be selected to provide a certain amount of stiffness to base plate 102 while maintaining a certain level of flexibility. As shown in FIGS. 1-7, medial forefoot bar 128 may be thin and wide. As also shown in FIGS. 1-7, medial forefoot bar 128 may have a flat profile and may be substantially flush with base plate 102 on both top surface 206 and bottom surface 108.

    [0026] Lateral forefoot bar 130 may extend from first lateral forefoot pad 124 to second lateral forefoot pad 126 such that lateral forefoot bar 130 connects first lateral forefoot pad 124 to second lateral forefoot pad 126. Lateral forefoot bar 130 may be disposed proximate lateral edge 116. Lateral forefoot bar 130 may extend in a direction that is substantially parallel to the portion of lateral edge 116 that lateral forefoot bar 130 is proximate. Lateral forefoot bar 130 may extend in a direction that is substantially parallel to longitudinal axis A. In some embodiments, lateral forefoot bar 130 may be substantially straight. As shown in FIG. 5, in some embodiments, lateral forefoot bar 130 may be slightly curved to follow the curvature of lateral edge 116. The size, shape, and/or location of lateral forefoot bar 130 may be selected based on a variety of factors. For example, the size, shape, and/or location of lateral forefoot bar 130 may be selected to provide a certain amount of stiffness to base plate 102 while maintaining a certain level of flexibility. As shown in FIGS. 1-7, lateral forefoot bar 130 may be thin and wide. As also shown in FIGS. 1-7, lateral forefoot bar 130 may have a flat profile and may be substantially flush with base plate 102 on both top surface 206 and bottom surface 108.

    [0027] First medial forefoot pad 120, medial forefoot bar 128, second medial forefoot pad 122, second lateral forefoot pad 126, lateral forefoot bar 130, and first lateral forefoot pad 124 may be joined together and may lie proximate a perimeter of forefoot region 107. This configuration may cause the pressure applied by the weight of the wearer to be distributed among the studs disposed in forefoot region 107. Furthermore, this joining may provide stiffness and support within forefoot region 107. The size and shape of the pads relative to the size and shape of the studs in forefoot region 107 may aid in distributing the weight of the wearer among the studs. As shown in the drawings, the pads may have a larger surface area relative to other parts of the pads. The larger surface area of the pads may provide stiffness and the smaller surface area of the pads may provide flexibility. For example, the smallest surface area of first medial forefoot pad 120 and first lateral forefoot pad 124 may occur where the two pads connect. Similarly, the smallest surface area of second medial forefoot pad 122 and second lateral forefoot pad 126 may occur where the two pads connect. The smallest surface area of these four pads may align along the center of forefoot region 107 to provide flexibility along the center of forefoot region 107. Such flexibility may aid in directional changes.

    [0028] Medial forefoot bar 128 and lateral forefoot bar 120 may be substantially parallel to one another. FIG. 6 shows base plate 102 in a first position shown in solid lines. In the first position, forefoot region 107 is bent. This first position may occur when a wearer is pushing off the ground with her forefoot. FIG. 6 shows a second position in dotted lines. The second position may occur when a wearer's foot is flat against the ground before or after pushing off the ground with her forefoot. The arrow shows the directions in which forefoot region 107 may be bent. In the embodiment shown in the FIGS. 1-7, medial forefoot bar 128 and lateral forefoot bar 120 may both be thin such that forefoot region 107 may bend into the position shown in solid lines in FIG. 6. In the embodiment shown in the FIGS. 1-7, medial forefoot bar 128 and lateral forefoot bar 120 may be thin such that structure 118 bends with the wearer's foot along the metatarsophalangeal joints. However, medial forefoot bar 128 and lateral forefoot bar 120 may also both be wide such that forefoot region 107 may be resilient such that structure 118 snaps back into the position shown in dotted lines in FIG. 6. Such resiliency creates a cantilever effect that adds to the propulsion created when the wearer pushes off forefoot region 107. As discussed in more detail below, the ribs and bars disposed on midfoot region 109 add stiffness to midfoot region 109. This stiffness causes a resistance to bending in midfoot region 109. Thus, pressure applied to structure 118 may cause structure 118 to bend in forefoot region 107, but the stiffness of midfoot region 109 may help resist bending in response to the applied pressure.

    [0029] Medial heel pad 154 may be disposed on heel region 111 proximate medial edge 112 and rearward edge 114. First lateral heel pad 156 may be disposed on heel region 111 proximate lateral edge 116. Second lateral heel pad 158 may be disposed on heel region 111 proximate lateral edge 116 and rearward edge 114. Second lateral heel pad 158 may be disposed between first lateral heel pad 156 and rearward edge 114. First lateral heel pad 156 and second lateral heel pad 156 may be aligned in a direction that is substantially parallel to lateral midfoot bar 152. First lateral heel pad 156 may be connected to second lateral heel pad 158. In some embodiments, first lateral heel pad 156 may taper toward forward edge 110 and toward rearward edge 114.
