[0016] Reference is now made to the drawings wherein like structures refer to like parts throughout. In Figure 1 a high-heel platform shoe 10 is shown having a solid bottom 16 that consists of a toe bottom 18 and a heel bottom 22. An EVA padding insole 26 having an exposed surface 28 and a bottom surface 32, and an EVA arch support 34 overly and are attached to the shoe bottom 16.
[0017] An adjustable toe belt upper 42 is attached to the toe bottom 18 using a plurality of metal screws 44 and extends over the toes while the platform shoe 10 is being worn. An adjustable ankle strap upper 48 is attached to the heel bottom 16 using the (matching) plurality of screws 44 of the platform shoe 10. An outsole 54 is attached at the bottom of the toe bottom 18 and the heel bottom 22.
[0018] Referring to Figure 2 the solid bottom 16 has a top surface 62 that continuously extends from the heel bottom 22 to the toe bottom 18. A plurality of toe apertures 68 are formed in the top surface 62 over the toe bottom 18 and a plurality of heel apertures 72 are formed in the top surface 62 over the heel bottom 22 - in both cases the apertures enhance the adhesion of the padding insole 26 to the solid bottom 16.
[0019] The toe bottom 18 also has an upper attachment surface 78 formed along a lateral length of the toe bottom 18 adjacent to the top surface 62. A plurality of securement apertures 82 are formed in the upper attachment surface 78 to assist in the attachment of the toe belt upper 42 - the securement apertures 82 receiving the plurality of metal screws 44.
[0020] The bottom surfaces of the arch support 34 is shaped to conform to the top surface 62, and is attached thereto utilizing an adhesive. The bottom surface 32 of the padding insole 26 is also shaped to conform to the top surface 62 of the solid bottom 16, as well as shaped to conform to an upper surface 86 of the arch support 34. An adhesive is also preferably used to attach the padding insole 26 to the top surface 62 and to the upper surface 86 of the arch support 34.
[0021] In a presently preferred embodiment the thickness of the padding insole 26 is varied along a longitudinal axis of the solid bottom 16, between the ball of the foot/toe area identified by thickness arrows A and the heel area identified by thickness arrows B. For such shoe designs having higher heels, such as that design depicted in Figure 2, the thickness at heel area B is reduced, for example 10 mm, as compared to the thickness at location A, for example 15 mm. Such reduction in thickness of the padding insole 26 provides the wearer with greater heel stability.
For other shoe designs, or where otherwise desired, the padding insole 26 is of uniform thickness in the range of between 10-15 mm.
[0022] The present invention is not limited to a particular style of sold bottom, and in Figure 3 a platform open-toed sandal 96 likewise makes use of the present invention. A platform sandal solid bottom 104 includes a sandal heel bottom 108 and a sandal toe bottom 112. The outsole 54 extends continuously over both the sandal heel and toe bottoms 108, 112. The adjustable toe belt upper 42 is attached to the sandal toe bottom 104 utilizing the plurality of metal screws 44.
[0023] The padding insole 26 and the padding arch support 34 shown in Figure 3 are both received by and attached to the sandal solid bottom 104 in a manner similar to that shown in Figures 1 and 2. As is depicted in Figure 4, the padding insole 26 extends over the arch support 34. The exact shape of the arch support 34 may vary from that shown in Figure 4, depending upon the nature of the shoe bottom, the overall shoe size, and other factors relating to or intended to enhance the comfort of the shoe wearer.
[0024] In Figure 5 the solid bottom 16 includes both a wood outsole 118 that extends from the heel area to the toe bottom 18, and a molded heel 124, such as might be fabricated from a strong plastic material. A great deal of variance can be had with the heel bottom 22 under the present invention, where the inventive arrangement of the padding insole 26 and the arch support 34 overlie and are attached to the solid bottom 16.
[0025] Similarly, the present invention contemplates creative variance of the upper, including both decorative and structural. In Figure 5 a multi-strap toe restraint 132 is attached to the toe bottom 18 and a serpentine belt ankle strap 136 is attached to the wood outsole 118 adjacent the heel. It is to be understood and appreciated that the present invention is not limited to the design or number or types of upper restraints - or to the configuration or material(s) used to fabricate the midsole and outsole to which the padding insole and arch support is attached.
[0026] In a presently preferred embodiment a wood unit bottom or a thermoplastic rubber bottom is topped with a 10-15 mm layer of exposed EVA foam having a soft density/hardness of between 30°-35° (Asker C Scale), and preferably not less than 30°, providing cushion underfoot. A second layer of EVA foam having a greater density/hardness, one of 70° presently preferred, is configured as an arch support and is sandwiched between the soft density EVA layer and the wood or thermoplastic rubber bottom. The outsole is preferably also fabricated out of EVA foam, having a density/hardness preferably in the range of 85°-90°.
[0027] The combined layers of EVA foam are preferably anatomically shaped to support the hollow arch area of the wearer's foot, with both layers shaped to follow the top surface of the unit bottom. The outer surfaces of the combined EVA foam layers are exposed, and are not wrapped by any other material (such as leather, fabric or synthetic leather).
[0028] The soft layer of EVA foam has direct contact with the foot of a wearer (no sock lining) and the combined EVA foam layers are glued to the top surface of the unit bottom. Both EVA foam layers are shaped to conform to the specific perimeters of the top surface of the unit bottom. The combined EVA foam layers are flexible and may be adapted to any of various heel heights, slopes, and pitches of the unit bottoms. In most cases the upper material is attached to the unit bottom using metal screws, nails, staples, and the like. The soft layer of EVA foam is exposed and is not attached to the upper material. The outsole is attached to the unit bottom and may consist of a 3 mm layer of rubber or a rubber-like material - or, as mentioned above, may consist of an EVA foam of density/hardness of between 85°-90°.
[0029] As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all the matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
