DETAILED DESCRIPTION

[0039] The present footwear includes a sole and a multi-level support member that is on the sole, where the multi-level support member provides different amounts of support in different areas of a user's feet to enhance a natural rolling motion of the feet while providing stability and cushioning to the feet during movement.

[0040] Referring now to FIGS. 1-13, an article of footwear 20, such as a shoe, includes a sole, generally indicated as 22, where the sole 22 includes a midsole 24 attached to an upper 26, and an outsole 28 attached to the midsole. The midsole 24 is made of a substantially rigid material and has a peripheral wall 30 and a bottom wall 32 attached to the peripheral wall 30 that has an upper surface 34 and a bottom surface 36. The peripheral wall 30 and the bottom wall 32 may be integrally formed together to form the midsole 24 or formed separately and attached together in a compression molding process, by using an adhesive or by another suitable attachment process.

[0041] In the illustrated embodiment, the midsole 24 is made with ethylene-vinyl acetate (EVA), but may also be made with thermoplastic polyurethane (TPU), a foam material or any suitable material or combination of materials. As shown in FIGS. 1-4, the outsole 28 is attached to a bottom surface 36 of the midsole 24 by an adhesive or by molding, and is made of rubber. The outsole 28 typically includes a plurality of tread members 38 that are configured to grip an underlying surface, such as the ground, during movement. It should be appreciated that the outsole 28 may be made of any suitable material or combinations of materials.

[0042] Referring to FIGS. 5-10, a multi-level support member 40 is placed on the midsole or embedded in the midsole 24 as shown in FIG. 10. The multi-level support member 40 includes a body 41 having a front end 42 and a rear end 44 and a length defined by the distance between the front end and the rear end. As shown in FIGS. 6 and 7, the body 41 of the support member 40 includes a medial member 46, a central member 48 and a lateral member 50 that each extend between the front end 42 and the rear end 44. In the illustrated embodiment, the medial member 46, the central member 48 and the lateral member 50 are integrally formed together to form the body 41. In an embodiment, the body 41 is formed by a molding process, such a compression molding process or an injection molding process. In another embodiment, the medial member 46, the central member 48 and the lateral member 50 are made separately and then attached together by molding, welding, gluing or joined by any suitable manufacturing method.

[0043] The medial member 46 extends along the medial side 52 of the body 41 and has a front curved part 54 that curves upwardly (away from an underlying surface) toward the front end 42 of the body 41, and a rear curved part 56 that curves downwardly toward an underlying surface at the rear end 44 of the body 41. A middle curved part 58 extends between the front curved part 54 and the rear curved part 56 and has a convex shape, i.e., the curvature faces upwardly relative to an underlying surface.

[0044] The central member 48 has a front curved part 60 that is curved upwardly away from an underlying surface and has a first end 62 and a second end 64, where the first end 62 has a width that is greater than a width of the second end 64. As such, the front curved part 60 of the central member 48 gradually widens from the second end 64 to the first end 62. It should be appreciated that the second end 64 may have a width that is greater than a width of the first end 62 of the front curved part 60 or the front curved part 60 may have a uniform width along the length of the front curved part. The central member 48 also includes a rear part 66 that is substantially straight and extends at an angle relative to a longitudinal axis LA extending along the sole. In this embodiment, the rear part 66 forms an angle relative to a longitudinal axis LA of the body 41 that is 80? to 120?. It should be appreciated that the rear part 66 may form any suitable angle relative to the longitudinal axis LA of the body 41. Similar to the front curved part 60, the rear part 66 has a first end 68 with a width that is greater than a width of the second end 70. As such, the rear part 66 of the central member 48 gradually widens from the second end 70 to the first end 68. It should be appreciated that the second end 70 of the rear part 66 may have a width that is greater than a width of the first end 68 or the rear part 66 may have a uniform width along the length of the rear part. As shown, a middle part 72 extends between the front curved part 60 and the rear part 66 and is substantially flat. In other embodiments, the middle part 72 may have a convex curvature (curve that extends away from an underlying surface), a concave curvature (curve that extends toward an underlying surface) or a combination of a convex curvature and a concave curvature.

[0045] The lateral member 50 extends along the lateral side 74 of the body 41 and has a front curved part 76 that curves upwardly (away from an underlying surface) toward the front end 42 of the body 41, and a rear curved part 78 that curves downwardly toward an underlying surface at the rear end 44 of the body 41. A middle curved part 80 extends between the front curved part 76 and the rear curved part 78 and has a convex shape, i.e., the curvature faces upwardly relative to an underlying surface. As shown, the radius of curvature of the middle curved part 80 of the lateral member 50 is less than the radius of curvature of the middle curved part 58 of the medial member 46. In this way, the middle curved part 58 of the medial member 46 provides additional support in the instep or arch area of the foot on the medial side 52.

[0046] Additional rigidity may be added or formed in the body 41 to provide additional support in different areas of a foot during movement. In the illustrated embodiment of the support member 40, the bottom surfaces 82a, 82b and 82c of the front curved parts 54, 60 and 76 of the medial member 46, the central member 48 and the lateral member 50 each have a protruding member or ridge 84a, 84b and 84c that forms recessed areas 86a, 86b and 86c on the upper surfaces 88a, 88b and 88c. The ridges 84a, 84b and 84c on the bottom surfaces 82a, 82b and 82c of the medial member 46, the central member 48 and the lateral member 50 provide additional structural support to the portions of the medial member, the central member and the lateral member in which the ridges are formed. The ridges 84a, 84b and 84c may be formed in one, two or all of the medial, central and lateral members 46, 48 and 50. Further, the ridges 84a, 84b and 84c may have the same shape and length or different shapes and lengths depending the desired support for a user's feet and the ridges 84a, 84b and 84c may be formed on any portion of the body 41.

[0047] Additionally, a central portion 90 of the body 41 includes two elongated oval openings 92 and 94 that separate the medial member 46, the central member 48 and the lateral member 50 in this area. The openings 92 and 94 provide additional flexibility to the central portion 90 of the body 41 so that the central portion may flex or bend more than other portions of the body 41 such as the front portion 96 and rear portion 98 of the body 41. The body 41 may have one opening or a plurality of openings depending on the desired flexibility. Further, one or more openings may be formed in any portion of the body 41 and may be any suitable shape, width and length.

[0048] In the above embodiment, the support member 40 is preferably made with a carbon-fiber reinforced material but may also be made with metal, a composite material or any suitable combinations of materials. Also, the support member 40 may have any suitable length and width and preferably has a thickness of 1.0 mm to 1.5 mm. It should be appreciated that the thickness of the body 41 of the support member 40 may be the same or vary along the length of the body.

[0049] Referring to FIGS. 11 to 13, the heights (distance above an underlying surface or a percentage of the thickness of the midsole) of the front parts 54, 60, 76, middle parts 58, 72, 80 and rear parts 56, 66 and 78 of the medial member 46, the central member 48 and the lateral member 50 are different in different areas of the body 41 of the support member 40. In FIG. 11, the height of the rear part 66 of the central member 48 is greater than the heights of the rear parts 56 and 66 of the medial member 46 and the lateral member 50. Specifically, the heights of the rear parts 56 and 78 of the medial and lateral members 46 and 50 are each fifty percent (50%) of the thickness of the midsole 24 and the height of the rear part 66 of the central member 48 is seventy-five percent (75%) of the thickness of the midsole 24. It should be appreciated that the heights of the medial, central and lateral members 46, 48 and 50 may be the same or different. The configuration of the rear parts 56 and 78 of the medial, central and lateral members 46, 48 and 50 causes the rear part 66 of the central member 48 to compress the midsole 24 before the rear parts 56 and 78 of the medial and lateral members 46 and 50 compress the midsole thereby providing additional support in the central area of a heel of a foot during impact with the ground. Further, when all of the rear parts 56, 66 and 78 compress the midsole, the rear portion 98 of the support member 40 provides added propulsion to user's feet while the curvature of the rear parts 56 and 78 of the medial and lateral members 46 and 50 facilitate a rolling motion of the feet.

[0050] In the central portion 90 of the support member 40 shown in FIG. 12, the height (percentage of the midsole thickness) of the middle part 72 of the central member 48 is greater than the heights of the middle parts 58 and 80 of the medial and lateral members 46 and 50. Further, the height of the middle part 58 of the medial member 46 is greater than the height of the middle part 80 of the lateral member 50. This configuration provides additional support in the arch area of the foot, which enhances stability and helps to resist pronation of the foot during movement while also helping to reduce fatigue.

[0051] In the illustrated embodiment, a cushion member 91 or a plurality of cushion members are placed on the support member to provide cushioning and comfort to a user's feet. Each cushion member is preferably made with a foam material but may also be made with EVA or other suitable material or combination of materials. The thickness of the cushion member or cushion members depends on the desired level of cushioning in different areas of the sole. The combination of the cushion member and the support member determine the amount of support and cushioning for a user's feet.

[0052] Referring to FIG. 13, the heights of the front parts 54 and 76 of the medial and lateral members 46 and 50 are less than the height of the front part 60 of the central member 48. In the illustrated embodiment, the heights of the front parts 54 and 76 of the medial and lateral members 46 and 50 are twenty-five percent (25%) of the thickness of the midsole 24 and the height of the front part 60 of the central member 48 is fifty percent (50%) of the midsole thickness. It should be appreciated that the heights of the front parts 54, 60 and 76 of the medial, central and lateral members 46, 48 and 50 may be the same or different depending on the desired support at the front portion 96 of the support member 40. In this embodiment, the lower heights of the front parts 54 and 76 of the medial and lateral members 46 and 50 help to facility the natural rolling motion of a user's feet while the higher height of the front part 60 of the central member 48 gradually provides rigidity and stiffness during compression of the support member 40 to help improve the push off or pushing force of the front area of the user's feet on an underlying surface such as the ground.

[0053] Referring to FIGS. 14 to 16, another embodiment of the support member is shown where the support member 100 includes a body 102 having a medial member 104, a central member 106 and a lateral member 108 as described above. In this embodiment, the medial member 104, the central member 106 and the lateral member 108 are each independently made and then attached together by a first attachment member 110 and a second attachment member 112. As shown in FIG. 14, the first and second attachment members 110 and 112 each have a generally rectangular shape with a width and length, where the length is sufficient to extend across at least a portion of each of the medial, central and lateral members 104, 106 and 108. In the illustrated embodiment, the first attachment member 110 and the second attachment member 112 are spaced from each other where the first attachment member 110 is positioned at or adjacent to a forefoot area of a user's feet and the second attachment member 112 is positioned at or adjacent to a heel area of the user's feet. It should be appreciated that the first and second attachment members 110, 112 may have the same shape, width and length or different shapes, widths and lengths. Also, the first and second attachment members 110 and 112 may be positioned at any positions along the length of the support member 100. In the illustrated embodiment, the first and second attachment members 110 and 112 are attached to the medial, central and lateral members 104, 106 and 108 by molding but may also be attached to the medial, central and lateral members using an adhesive, by welding or using any suitable attachment method. As shown, the medial, central and lateral members 104, 106 and 108 are attached together so that there are spaces between each member. This allows the medial, central and lateral members 104, 106 and 108 to move, i.e., compress or flex, independently of each other, during movement.

[0054] Referring to FIG. 17, another embodiment of the support member is shown where the support member 114 includes a body 116 having a medial member 118 and a lateral member 120 separated from each other to define a space 122.

[0060] The central member 210 has a front curved part 222 that is curved upwardly away from an underlying surface and has a first end 224 and a second end 226, where the first end 224 has a width that is greater than a width of the second end 226. As such, the front curved part 222 of the central member 210 gradually widens from the second end 226 to the first end 224. It should be appreciated that the second end 226 may have a width that is greater than a width of the first end 224 of the front curved part 222 or the front curved part 222 may have a uniform width along the length of the front curved part. The central member 210 also includes a rear part 228 that is substantially straight and extends at an angle relative to a longitudinal axis extending along the sole. In this embodiment, the rear part 228 forms an angle relative to a longitudinal axis LA of the body 202. It should be appreciated that the rear part 228 may form any suitable angle relative to the longitudinal axis LA of the body 202. Similar to the front curved part 222, the rear part 228 has a first end 230 with a width that is greater than a width of the second end 232. As such, the rear part 228 of the central member 210 gradually widens from the second end 232 to the first end 230. It should be appreciated that the second end 232 of the rear part 228 may have a width that is greater than a width of the first end 230 or the rear part 228 may have a uniform width along the length of the rear part. As shown, a middle part 234 extends between the front curved part 232 and the rear part 228 and is substantially flat. In other embodiments, the middle part 234 may have a convex curvature (curve that extends away from an underlying surface), a concave curvature (curve that extends toward an underlying surface) or a combination of a convex curvature and a concave curvature.

[0061] The lateral member 212 extends along the lateral side 236 of the body 202 and has a front curved part 238 that curves upwardly (away from an underlying surface) toward the front end 204 of the body 202, and a rear curved part 240 that curves downwardly toward an underlying surface at the rear end 206 of the body 202. A middle curved part 242 extends between the front curved part 238 and the rear curved part 240 and has a convex shape, i.e., the curvature faces upwardly relative to an underlying surface. As shown, the radius of curvature of the middle curved part 242 of the lateral member 212 is less than the radius of curvature of the middle curved part 242 of the medial member 208. In this way, the middle curved part 242 of the medial member 208 provides additional support in the instep or arch area of the foot on the medial side 214.

[0062] In this embodiment, the body 202 of the support member 200 includes at least one medial side support 244 and at least one lateral side support 246 that each extend downwardly from the body 202 on the medial side 214 and the lateral side 212 of the body 202. In the illustrated embodiment, the medial side support 244 and the lateral side support 246 are located at the middle of the body 202 but it should be appreciated that the medial side support 244 and the lateral side support 246 may be located at an location along the medial and lateral sides of the body 202. It should also be appreciated that the medial side support 244 and the lateral side support 246 may be at the same location on the medial and lateral sides of the body 202 or at different locations on the body. Furthermore, the length, width, height and shape of the medial side support 244 and the lateral side support 246 may be the same or different. The medial side support 244 and the lateral side support 246 extend along a surface of the midsole and helps to limit lateral movement of the support member 200 on the sole and provide additional rigidity to the medial and lateral sides of the body 202. In another embodiment, the body 202 of the support member 200 includes only one of the medial side support 244 or the lateral side support 246. In a further embodiment, at least one of the medial side support 244 and the lateral side support 246 extends upwardly from the body 202 along the surface of the midsole. It should be appreciated that the medial and lateral side supports 244, 246 may both extend upwardly or downwardly from the body 202 or may extend in different directions from the body. In an embodiment, at least a portion of at least one of the medial side support 244 and the lateral side support 246 are exposed on visible on an outer surface of the sole.

[0063] In the above embodiment, the support member 200 is preferably made with a carbon-fiber reinforced material but may also be made with metal, a composite material or any suitable combinations of materials. Also, the support member 40 may have any suitable length and width and preferably has a thickness of 1.0 mm to 1.5 mm. It should be appreciated that the thickness of the body 202 of the support member 200 may be the same or vary along the length of the body.

[0064] While particular embodiments of the present footwear and associated support member are shown and described, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
