Navicular support tennis shoe
First Claim
1. A sports shoe having a sole and an upper attached thereto, the upper being made, at least substantially, of relatively pliable material and having opposite sides, one side corresponding to the inner side of the foot, and the other side corresponding to the outer side of the foot, and the upper also having a back portion adapted to wrap around the heel of the foot, and a supporting means including a tension bearing support member, made of a relatively rigid, high modulus, low elongation material, on the side of the upper corresponding to the inner side of the foot, said support member having a free upper end and extending downwardly and rearwardly over an area of the navicular bone of the foot, means for rigidly attaching said support member to said back portion, in an area behind the os calcis bone of the foot and for rigidly attaching said member to said sole in an area rearward of said free end, wherein said member is thereby rigidly attached in tension bearing engagement to said sole and back portion, and means for releasably attaching free end in rigid tension bearing engagement to a portion of the sole located on the other side of the upper thereby to provide a non-resilient, medio-lateral support between the os calcis and navicular bones of the foot.

Abstract
A sports shoe, preferably for tennis includes a rigid stirrup member with a pair of first portions that extend downwardly and rearwardly, on opposite sides of the shoe, to the sole, and a second portion that extends around the back of the shoe and is connected between the first portions. The first portion on the inside part of the shoe extends over the navicular bone, and the second portion extends behind the calcaneous bone of the foot. When the first portions are fastened together, the stirrup member encapsulates the calcaneous, navicular, and talus bones to provide medio-lateral support to critical stress-bearing bones and joints.

7. A sports shoe comprising:
-
a sole; an upper formed of relatively soft material attached to said sole, said upper including an opening to define a foot receiving space; a stirrup member made of a relatively rigid, high modulus, low elongation material, said stirrup member having opposed free ends lying forward of said opening, a pair of opposed first portions extending downwardly and rearwardly on either side of the shoe and being rigidly attached to said sole, and a second portion extending from one of the first portions, around behind the opening, to the other first portion, wherein the first portion on the side of the shoe corresponding to the inner side of the foot is positioned at least substantially to extend downwardly and rearwardly over the navicular bone of the foot, and wherein the second portion is positioned to extend behind the os calcis bone of the foot; and fastening means for releasably attaching said free ends of the stirrup member to one another in rigid tension bearing engagement. - View Dependent Claims (8, 9, 10, 11)

12. A sports shoe comprising:
-
a sole having forward and rear portions, the rear portion being relatively thick and inflexible; an upper formed of relatively soft material attached to said sole, said upper including an opening to define a foot receiving space; a stirrup member, made of a relatively rigid, high modulus, low elongation material, said stirrup member having opposed free ends lying forward of said opening, a pair of opposed first portions extending downwardly and rearwardly on either side of the shoe to a pair of respective means for connecting, in rigid tension bearing engagement, the lower end portions of the stirrup members, lying on opposite sides of the shoe, to the rear portion of the sole, wherein the first portion on the side of the shoe corresponding to the inner side of the foot is positioned to extend downwardly and rearwardly over the navicular bone of the foot, and wherein the second portion is positioned to extend behind the os calcis bone of the foot; and fastening means for releasably attaching said free ends to one another in rigid tension bearing engagement. - View Dependent Claims (13, 14)
