Definitions

  • the present invention relates to insoles for shoes and, more particularly, this invention relates to an adjustable orthotic by which the eversion and abduction of the tarsal and metatarsal joints can be controlled by the user.
  • Misalignment of the foot can cause minor trauma such as inflammation, blisters, rashes, calluses, corns, ingrown toe nails or more aggravated conditions such as bunions or bone spurs, typically in the heel area.
  • Over-the-counter insoles are available to relieve minor discomfort. However, they are available in fixed sizes and thicknesses. It is possible to reduce discomfort and promote healing of inflamed areas by custom-cutting thick cushioning products such as Moleskin® into pads which can be locally adhered to the traumatic area or adjacent to the traumatic area. Pads and insoles only treat the symptoms of the misalignment and simply reduce irritation and attempt to prevent further trauma by reducing pressure, rubbing, or abrasion on the sensitive area of the foot. Sometimes surgery is utilized to remove the calluses, corns or bunions.
  • orthotics are prescribed by medical specialists such as orthopedic doctors, podiatrists or doctors specializing in sports medicine. After extensive physical measurements of the patient, a plaster impression of the foot is taken. The orthotic is manufactured from the impression to specifications provided by the doctor as to the degree of pronation correction required.
  • a soft layer of foam can be applied to the top or bottom surface of the orthotic to provide comfort and to prevent the orthotic from sliding when in a shoe.
  • Orthotics are very expensive, on the order of several hundred dollars a pair. Since they are so expensive, they are usually designed to provide the final correction. The degree of correction can be so severe that the orthotic causes such pain and discomfort to the patient, that it discourages usage of the orthotic and eventually it is no longer used. It is not possible to adjust the fit of the hard plastic orthotic.
  • Greenwalt U.S. Patent No. 4,694,590 discloses an arch support unit containing preformed resilient elements located in the arch area.
  • the support is fastened to the shoe by hook and loop fastener elements located in the heel portion of the support and adhered to the support and to the insole of the shoe.
  • the heel cushion disclosed by Scheuerman (U.S. Patent No. 4,928,404) contains a soft insert of silicone rubber opposite the location of a heel spur in the patients heel.
  • Andrews discloses a molded, resilient foam shoe insert having depressions 18 in the heel and in the arch support region.
  • the depressions can be filled with adhesively secured, resilient plastic inserts 19 or may be left empty as dictated by the comfort of the wearer.
  • Engle U.S. Patent No. 4,930,232 discloses a multilayer laminated permanently adhered shoe insole formed of materials of different shore hardness.
  • Kristan U.S. Patent No. 2,928,193 discloses a composite leather-cork shoe lining filled with resilient pads of sponge or with foam rubber glued to the lining.
  • Bittner U.S. Patent No. 3,143,812 discloses a thermoplastic insole that can be sized to shape by tearing off portions of the sole along heat sealed seams.
  • the prior insoles were mainly designed to alleviate pain and discomfort. Most of these products were formed of soft resilient materials having no memory or very hard, rigid materials that must be preformed to a desired shape. Adjustable thickness is provided only in set locations and usually by removing pads to form cushions opposite painful areas of the foot.
  • An insole having provision for placement of pads of varying thickness anywhere along the bottom surface of an insole is disclosed and claimed in application Serial No. 07/690,661, filed April 24, 1991, the disclosure of which is expressly incorporated herein by reference.
  • the insole is formed of a deformable plastic with memory.
  • the bottom surface contains longitudinal strips of loop or hook material along the bottom surface of the insole.
  • the surface may also contain an index scale for locating the correct place to position a pad.
  • a shoe insert for placement on an inside surface of a shoe comprising in combination:
  • the present invention provides a further improvement in the design of an insole that allows it to perform as an orthotic.
  • the insole can be modified by the user to contain elevated and/or relieved areas anywhere on the insole to form an orthotic-like device.
  • the user can create a customized therapeutic device capable of relieving pain and stress and capable of biomechanically correcting or alleviating misaligned conditions in the patient's foot. More expert alignment can be provided by a doctor of medicine trained in correcting misalignment of the feet.
  • the orthotic of the invention provides infinite adjustability in the location and thickness of the orthotic at any location.
  • the orthotic can be adjusted and shaped at a doctor's clinic.
  • the custom-shaped orthotic can be the permanently prescribed orthotic or can be a temporary device until a permanent orthotic is fabricated.
  • the custom-configured orthotic can be shaped to provide only a fraction of the correction initially and the pads can be increased or decreased in thickness and/or location to provide gradual and more comfortable correction.
  • the patient can be provided with a supply of pads of varying thickness and be allowed to change the pads under supervision of the clinic without the expense and inconvenience of numerous visits to the physician.
  • the insole of the invention is designed to permit the pads to be secured to the top or bottom surface. Since feet are symmetrical this allows the same insole to be used on the right or left foot permitting sale of single insoles. The tooling and manufacturing costs are significantly reduced.
  • the invention also includes specially shaped inclined ramps which when appropriately located provide pronation correction.
  • the invention also provides pads with all edges smoothed to provide comfort to the user.
  • the invention also relates to use of improved materials and manufacturing processes to form the insole.
  • the shoe insert 10 of the invention is a multilayer laminate in the shape of a shoe insole.
  • the insert 10 comprises a base 12 and an outer pad attaching layer 14.
  • the layer is preferably formed of a cloth having loops 16 to which pads having a layer of hooks can attach.
  • the cloth can form the upper surface of an insole or be disposed toward the bottom surface.
  • the layer 14 is attached to the base 12 by bonding, suitably by means of a layer 18 of adhesive.
  • a cushioning layer 20 of closed cell foam or other elastomeric material can also be present.
  • the base is preferably formed of a flexible but deformable plastic with memory such as 0.25 to 2.54 mm (10-100 mil) high density polyethylene (HDPE), generally from 0.5 to 1.27 mm (20-50 mil). Under the force of the weight of the user, the HDPE layer will deform and mold to the shape of the foot. HDPE also presents a low friction surface when used as the upper surface of the insert. The smooth surface reduces irritation and can result in reduction of inflammation and swelling.
  • HDPE high density polyethylene
  • the cloth layer is preferably formed of a synthetic resin such as a Nylon polyamide and contains a loop surface adapted for releasable engagement by hooks.
  • the loop cloth is commercially available laminated to foam backing layers such as polyester or polyurethane foam cores in various thicknesses. These materials have been used in industrial applications such as display panels office partitions, bulletin boards, etc. These loop fabrics are washable with water and detergent or can be cleaned with organic solvent to remove common stains.
  • An example of a commercial loop cloth is Veltex Bright materials.
  • the Veltex nylon cloth materials have a thin, low profile, will not fray and will not pick up lint. They are available in many colors and can be attached by pressure sensitive adhesives, tapes, ultrasonic, or thermal bonding.
  • a cloth layer 22 and foam layer 20 are adhered to the deformable base 26.
  • the lower surface of the base contains a layer 28 of adhesive covered by a protective sheet 30.
  • the adhesive layer 28 is exposed.
  • the adhesive layer 28 will adhere to the surface 38 of the insole.
  • the protective sheet 30 is then removed.
  • the cloth layer 22 is exposed for adherence of pads containing cooperatively engaging hook material.
  • the preferred hook materials used with the pads are also preferably formed of a thin, low profile, non-frayable material.
  • the hooks can form bonds with the loop material of from 357 to 1786 kg/m (20 to 100 pounds per inch), usually around 1072 to 1429 kg/m (60-80 pounds per inch).
  • Preferred materials have good elongation properties.
  • the preferred hook materials are formed of Nylon. They can be precoated with adhesive.
  • a suitable commercial material is ULTRA-MATE hook materials.
  • Each pad contains a cushioning layer formed of a resilient material, suitably a closed cell foam such as PORON.
  • the pads can vary in thickness but generally are from about 0.32 cm (1/8 inch) to about 1.27 cm (1/2 inch) in thickness.
  • the hook material is bonded to the cushioning layer by adhesive, thermal or ultrasonic bonding or by adhesive tape.
  • a thick pad element 40 has a cushioning layer 42 attached to a layer 44 of hook material by a film 46 of adhesive.
  • the thin pad element 48 shown in Figure 8 contains a thinner layer 50 of cushioning material.
  • the pronation pad 52 illustrated in Figure 9 includes an inclined cushioning layer 54.
  • the pad 56 illustrated in Figure 10 has rounded edges 58, 60 and can include a top layer 62 of hook or loop material so that pads can be stacked as shown in Figure 11.
  • the lowermost pad 70 has a bottom hook layer 72 attached by adhesive film 74 to a cushioning layer 76 and an upper loop cloth layer 78 attached to the cushioning layer 75 by an adhesive film 80.
  • Figures 12 and 13 illustrate pads with apertures which can relieve pressure when placed under sensitive areas of a foot.
  • the larger pad 80 shown in Figure 12 has a large oval aperture 82 cut out of the middle of the pad.
  • the edge 84 of the cut-out is preferably smoothed or chamfered to provide comfort to the user as his foot enters the aperture 82.
  • the attachment surface is formed of detachable material such as hook cloth 86 or loop cloth, not shown.
  • the pad 80 can contain an internal layer 8 of cushioning material, not shown, and an outer layer 90 which can be a smooth cloth such as loop cloth as shown in Figures 17 and 18.
  • the smaller pad 100 shown in Figure 13 has a circular opening 92, otherwise the construction is identical to that of pad 80.
  • the pad 100 is intended to be placed over inflammations on or in the heel of the user such as a heel spur. Again the edge 94 is chamfered for comfort.
  • the pad can be cut in half and trimmed by the user to form a smaller opening.
  • the two halves are reassembled by placing the openings adjacent each other with the hooks engaging the loops present on the surface of a shoe insert.
  • the pads can be attached to the top surface or bottom surface of the shoe insert.
  • inclined or ramp pad 101 is attached to the loop cloth surface 102 of a shoe insert 110.
  • the pad 101 has a bottom hook cloth layer 104, and inclined shaped cushioning layer 106 and an upper smooth layer 108 such as loop cloth.
  • the shoe insert 102 is disposed with the loop cloth surface 104 facing upwardly.
  • the pad 101 is attached across the arch and metatarsal area with the thicker edge 112 disposed along the outer edge 111 of the foot. This lift will pronate the foot inwardly to correct bow leg conditions.
  • the loop surface 102 of the shoe insert 110 is disposed downwardly in Figures 16 and 17.
  • the hook layer 104 of the pad is attached to the loop cloth 102 with the thicker edge 111 disposed among the inner side edge 116 of the shoe insert along the arch-metatarsal region of the foot. This assembly will pronate the foot outwardly to correct a fallen arch or knock-knee condition.
  • the base 120 as shown in Figures 18 and 19 can have a loop cloth layer 122, 124 on both the top and bottom surfaces.
  • the cloth layers 122, 124 are adhered to a deformable film 126 of HDPE or other resin by adhesive layers 128, 130. Cushioning layers, not shown, may be present beneath the cloth layers.
  • a metatarsal pad 80 can be attached to the top loop cloth layer 122 and a heel pad 100 can be attached to the bottom loop cloth layer 124, as shown.
  • Figure 20 illustrates the use of pressure sensitive adhesive transfer tapes to manufacture the pad-receiving base for the shoe insert.
  • Transfer tapes are marketed in the form of a thin strip of pressure-sensitive adhesive preapplied to a release liner and wound into a spiral on a hub.
  • the transfer tapes are preferred over liquid adhesives, hot melt adhesives, staples, waxes or thermal or flame bonding. Heat may distort the cushioning layer or the HDPE base.
  • the strip of adhesive As the strip of adhesive is released from the liner it is sticky on both surfaces. It is readily automated to be used in continuous manufacturing operations. It is easy to quickly apply a neat precise strip of clean, dry adhesive strips 131, 132 such as 3MF-927 transfer tape to both sides 134, 136 of cushioning layer 138 such as a 62 mil thick layer of Poron resilient material.
  • the loop cloth layer can be flame bonded to the cushioning material as a first operation.
  • the cloth covered cushion layer can be adhesively bonded to the HDPE plastic base by means of adhesive transfer strips.
  • Another alternative is to apply a second layer of loop cloth or loop cloth-cushion laminate to the other surface of the base.
  • Figure 21-22 illustrates another embodiment of the invention.
  • the pads must be precisely located. If they intrude under an inflamed area, it is very painful.
  • a visual index scale 160 can be bonded to the cushioning layer 162 by a film of adhesive 164 or to the cloth layer 166.
  • the cloth layer can be divided into 2 segments 168, 170 on each side of the scale 160.
  • the scale could also be printed or silk-screened directly onto the cloth layer 166.
  • a film 172 of deformable plastic is bonded by a film 174 of transfer tape or other adhesive means to the other surface of the cushioning layer 162.
  • a blister package 140 includes a pair of low friction insert 142, each having an index scale 144 thereon, with flanking strips 146 of adhesive or Velcro type fastening material.
  • the user may use the scale to establish and maintain the discrete and movable cushion elements at the best locations that he discover with use. Normally the insert would be supplied fully covered with elements, but only three per insert are shown in Figure 23 to help make the scale visible. Three groups of replacement cushion elements 150, 151, and 152 are also included that have a variety of thicknesses to help custom shape the insert. Even if the users foot shape requirements change with time, the kit of Figure 23 allows continuing modification of the insert to an optimal configuration.
