  • [0025]
    Different moldable urethanes like EVA may be utilized for different firmness for the arch support to make the arch support stiff with three firmness settings; low firmness, medium firmness and heavy firmness. All firmness settings may be flexible at the insole. The insole may be comfortable, flexible, light-weight, creates a barrier against hot and cold temperatures and may be non-conductive unlike other protective insoles that may be made with a stainless steel plate or that may be constructed with a stainless steel plate incorporated in the sole of the footwear.
  • [0026]
    The insole may also hold a multiple layer protective material, such as non-metallic, puncture resistant and midsole material or SWEN-FLEX® material, puncture resistant insole materials or LENZI EGISTO PS5 ES L-PROTECTION® material, Terylene Cotton or TC cotton material or cut, abrasion, penetration-resistant protective apparel or TURTLE SKIN® that may be coupled together. The multiple layer protective material, the SWEN-FLEX® material, puncture resistant insole materials or LENZI EGISTO PS5 ES L-PROTECTION® material, Terylene Cotton or TC cotton material or cut, abrasion, penetration-resistant protective apparel or TURTLE SKIN® may be a fabric but may be any type of suitable material. The LENZI EGISTO PS5 ES L-PROTECTION® material, TC cotton material or TURTLE SKIN® may be non-conductive and have at least three or more layers of fabric, with a double-faced weft, made of relatively high wear resilient polyester fibers that may be coupled together by a thermoplastic film or an adhesive resin. Each of the layers of the material may be treated by a coating of polyurethane and/or acrylic resin that may be enriched with micronized ceramic materials in the form of silicates, such as aluminum silicate.
  • [0027]
    Moldable closed cell foams may be utilized to make the SWEN-FLEX® material and the LENZI EGISTO PS5 ES L-PROTECTION® material to hold the orthotic shape of the removable footwear insert with or without the heel cup. The moldable closed cell foams may come in different suitable colors, thicknesses and firmness depending on the relative firmness of the arch support and heel cup that may be desired by a user. The moldable closed cell foams may help distribute the weight of a user's body evenly over the entire area of a user's foot and sole. As previously described, EVA may be one of the closed cell foams made from ethylene vinyl acetate and blended copolymers and has a high level of chemical cross-linking, that may result in a semi-rigid product with a fine uniform cell structure that may be suitable for utilization in a wide variety of environments and applications. Benefits of EVA and other types of closed cell foams may include relatively good impact and vibration absorption, relatively good weather and chemical resistance including splash resistance to oils and fuels, relatively good acoustic and thermal insulation properties, relatively good buoyancy with low water absorption and relatively good suitability for thermo-forming and thermo-molding.
  • [0028]
    An open cell urethane material may be utilized as a cushioning and shock absorption material and also helps to maintain the orthotic shape of the removable footwear insert when using the SWEN-FLEX® and/or the Lenzi Egisto. Open cell urethane material may be available in a wide variety of colors, thicknesses, densities and surface textures to accommodate almost any activity, from everyday utilization to the rigorous demands of high-impact sports and exercise. Open cell urethane material may have a maximum retention of comfort and flexibility and may be made without plasticizers, which means the open cell urethane material will not shrink or become brittle and crack with age. Open cell urethane material may retain a like-new softness and flexibility, which may result in a high degree of impact absorption with more shock absorption and less impact to feet and joints. In side-by-side drop weight tests, open cell urethane material outperformed vinyl sponge, neoprene sponge, sponge rubber, LATEX® foam and other solid viscoelastic material. Open cell urethane material may form permeable layers that form a breathable layer to help feet stay dry and cool and draw water vapor and perspiration away. Open cell urethane material may also have excellent compression set resistance which enables durable, long-term performance for gasketing, sealing and cushioning. Open cell urethane material may also have low-out gassing and non-fogging and contain no plasticizers or residual chemicals to contaminate any device the open cell urethane material forms. Open cell urethane material may not become brittle and crumble and may be non-corrosive to metal and may be inherently flame retardant without the utilization of additives. Many of the open cell urethane material may meet flammability requirements of UL HBF and MVSS 302. Engineered open cell urethane material may also offer a wide modulus in the range of approximately 2 to 90 psi @ 25% deflection for more design versatility requirements. Open cell urethane material also may have good chemical resistance, may be easy to fabricate, die-cut cleanly and work with a broad range of adhesives and may have a broad range of formulas and thicknesses in the range of approximately 0.012 inches to 0.500 inches (i.e., 0.43 mm to 12.7 mm).
  • [0029]
    A thermoplastic hot melt film adhesive may be utilized to couple the insole, the multiple layer protective material, the SWEN-FLEX®, the Lenzi Egisto, the TC cotton material or TURTLE SKIN® and the open cell urethane material may be heat activated in the approximate range of 140 to 340 degrees Fahrenheit. A second adhesive may include a HM 8545 adhesive that may also be utilized as a fastener. A third adhesive such as a pressure activated adhesive (no number) may also be applied and couple the insole, multiple layer protective material, SWEN-FLEX®, Lenzi Egisto, TC cotton material or TURTLE SKIN® and the open cell urethane material together and may be heat activated in the approximate range of 140 to 400 degrees (Fahrenheit) depending on what specific previously mentioned materials may be utilized. A rubber welt may also be utilized as a cushioning material.
  • [0030]
    FIGS. 6A-6C illustrates a flow chart of a first method for manufacturing a removable footwear insert 600, in accordance with one embodiment of the present invention. The first layer of the removable footwear insert 600 may be a protective material or fabric. A layer of adhesive contact cement that may be specifically chemically formulated to couple open and/or closed celled urethanes and or polyurethanes to the protective materials and fabrics may be then applied 610. An additional adhesive may be put on top of a SWEN-FLEX® material, or Lenzi Egisto or other protective materials or fabrics 620. A layer of thermoplastic hot melt film may be then placed on top of the protective material 630 and a layer of moldable urethane may be placed on top of the thermoplastic hot melt film 640. A layer of thermoplastic hot melt film may be placed on top of the moldable urethane 650 so that a layer of colored urethane may be placed on top of the thermoplastic hot melt film 660 which may be on top of the moldable urethane. Then a layer of thermoplastic hot melt film may be placed on top of the colored urethane 670 so that a layer of materials, fabrics, amarelle or moisture resistant fabric and logo may be compressed together and heated to activate the thermoplastic hot melt film which molds and couples all layers to produce an orthotic removable puncture resistant insole that may be trimmed to fit any footwear 680 forming an assemblage.
  • [0031]
    Other thicknesses of urethanes may be utilized to hold the protective material or materials to an orthotic shape, although the thickness of one embodiment of the insole may be approximately ¼ inch or other suitable thickness. The entire assemblage may be then put in an orthotic mold, then pressed, cut and heated to hold all layers of material or fabrics together 690. Other thicknesses of moldable urethane's or other moldable materials that may be well known in the art may be utilized to hold the protective materials to the orthotic shape. A logo may also be disposed on top of the removable footwear insert if desired by a user 692. The moldable urethane and the urethane may also be utilized to hold the protective material or fabric to the orthotic shape 694. The moldable urethane may also be placed on top of the thermoplastic hot melt film which may be on top of the protective material and then a layer of thermoplastic hot melt film may be placed on top of the moldable urethane 612. Then the urethane may be placed on top of the thermoplastic hot melt film which may be on top of the moldable urethane 614. A layer of thermoplastic hot melt film may be placed on top of the sized and colored urethane and then fabric that may be of any suitable color may be placed on top of the thermoplastic hot melt film which may be on top of the sized and colored urethane 616. Other thicknesses of moldable urethane's other types may be utilized to hold the protective material or fabric to the orthotic shape. It may be then all put in an orthotic mold, then pressed, cut and heated to hold the layers of material and fabrics together 618.
  • [0032]
    FIGS. 7A-7C illustrates a flow chart of a second method for fitting a removable footwear insert 700, in accordance with one embodiment of the present invention. A layer of adhesive may be put on top of the protective materials 710 and then the adhesive may be put onto a layer of any size and color of urethane 720. The protective materials and urethane may be then heated to approximately 400 degrees (F.) 730 where both adhesive sides may be then sandwiched together and may be then pressed with a roll pin type action and may be then dried 740. After drying, the protective materials and urethane will be stamped out into the shape of a flat non-orthotic insole that may be trimmed to fit into any piece of footwear to cover and protect 100% of the user's sole 750. This may be an improvement over many stainless steel plated insoles that may only cover and protect approximately 85% of the user's sole. Other suitable thicknesses of suitable moldable urethane's or other moldable materials that may be well known in the art may be utilized to hold the protective material or fabric to the orthotic shape of the insole. Urethane foam may also be injected into an orthotic mold, cured and taken out and a layer of adhesive may be applied on the bottom of the molded urethane foam 760. Adhesive may be then put on top of the protective material and the molded urethane may be placed on top of the protective material 770 and additional adhesive may be placed on top of the molded urethane and moisture resistant material or other types of material heated and pressed to hold all of the layers of material and adhesive together 780. A logo may also be disposed on top of the material 790. Adhesive may also be placed on top of the protective material 712 and a moisture resistant material may be placed on top of the protective material 714 and may be heated and pressed together to couple the adhesive and protective material together 716.
  • [0033]
    The removable footwear insert may come in a plurality of styles. The first style may be a flat protective insert without an orthotic or an orthopedic insole and no flat cushion adhered to it on either side. The insert may come in two precut sizes. One size may be a men's size thirteen that may be trimmed down to any size. The other size may be a men's size sixteen that may be trimmed down to a men's size thirteen and a half. Either size may be trimmed to fit by the end user. The other sizes may be manufactured to be precut to any size. This may be done with a press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the protective material into one or more sizes. The insert may be placed underneath the original footwear insole or on top of the original footwear insole or may replace the original footwear insert or insole. The company and product logo may be either stamped or hot melted in the middle of the insert on the top side.
  • [0034]
    The second style may be also a flat protective insert without an orthotic or an orthopedic insole and without a flat cushion adhered to it on either side. The bottom of the protective material may be facing upward and then an adhesive may be sprayed on or rolled. Then it may be covered with a non-adhesive wax paper or plastic that will not adhere to the adhesive so that it would be a peel and stick concept. Then the sheet of protective material may be placed into a press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed and the plate with the sized forged dies comes down cutting the protective material. The insert may come in two precut sizes. One size may be a men's size thirteen that may be trimmed down to any size. The other size may be a men's size sixteen that may be trimmed down to a men's size thirteen and a half. Either size may be trimmed to fit by the end user for 100% protection. The other sizes may be manufactured to be precut to any size. Then the end user may peel the non-adhesive paper or plastic off the bottom and place the insert underneath the original insole. This will allow the protective insert to be coupled to the inner sole of the footwear to reduce slippage and/or movement. The end user may utilize it as a replacement insert for the footwear and be protected from unforeseen dangers of sharp objects penetrating the sole of the footwear injuring the foot sole of the end user. The company and product logo may be either stamped or hot melted on the top of the fabric and in the middle of the insert.
  • [0035]
    The third style may be also a flat protective insert without an orthotic or orthopedic insole and without a flat cushion adhered to it on either side. Spraying or rolling an adhesive on the top of the sheet of protective material then covering it with a non-adhesive wax paper or plastic that does not adhere to the adhesive. The sheet of protective material may be flipped over on the other side and do the same process so that it would be a peel and stick concept. Then the sheet of protective material may be placed into a press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the protective material. The insert may come in two precut sizes. One size may be a men's size thirteen that may be trimmed down to any size. The other size may be a men's size sixteen that may be trimmed down to a men's size thirteen and a half. Either size may be trimmed to fit by the end user for protection over the entire sole of a user's sole. The other sizes may be manufactured to be precut to any size. Then the end user may peel the non-adhesive paper or plastic off the bottom and place the insert underneath the original insole. This may allow the protective insert to be coupled to the inner sole of the footwear to reduce slippage and/or movement. Then the end user may peel-off the wax paper or plastic from the top of the protective insert that may be already in the footwear and place's the original insole back into the footwear on top of the adhesive protective insert which will couple together to reduce slippage and/or movement. The end user could utilize it as a replacement insert for the footwear and be protected from unforeseen dangers of sharp objects penetrating the sole of the footwear injuring the foot sole of the end user. The company and product logo may be either stamped or hot melted in the middle of the insert on the top side.
  • [0036]
    The fourth style may be the flat protective insert without an orthotic or an orthopedic insole but with a flat cushion that may be adhered to the top of the protective materials while adhering a cushion material such as PORON™, rubber, EVA, Gel-Coat, polyurethane, urethane, etc. to the sheet of protective materials. The top side of the protective materials may be sprayed or rolled with an adhesive then the cushion material may be laid on the top of the adhesive that may be on top of the protective materials. After some time passes, then the sheet of protective material with the cushion on the top side may be placed into the press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the size(s). The protective insert with the cushion on top may either be manufactured without an adhesive on the bottom that would be utilized to replace the original footwear insert. An adhesive may also be sprayed or rolled to the bottom of the protective insert.
  • [0037]
    The process of manufacturing the protective insert with an adhesive on the bottom may be that the protective material may be flipped where the bottom may be facing upward and the cushion may be facing downward. Then an adhesive may be sprayed or rolled onto the material and covered with a non-adhesive wax paper or plastic that will not adhere to the adhesive so that it would be a peel and stick concept. Then the sheet of protective material may be sled into the press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the size(s). This would allow the end user to remove the original insole of the footwear, peel the non-adhesive wax paper or plastic off the bottom of the protective insert and place it onto the inner shoe sole of the footwear and press down. This will allow the protective insert to be coupled to the inner sole of the footwear to reduce slippage and/or movement. The insert may come in two precut sizes. One size may be a men's size thirteen that may be trimmed down to any size. The other size may be a men's size sixteen that may be trimmed down to a men's size thirteen and a half. Either size may be trimmed to fit by the end user for 100% protection. The other sizes may be manufactured to be precut to any size. The end user could utilize it as a replacement insert for the footwear and be protected from unforeseen dangers of sharp objects penetrating the sole of the footwear injuring the foot sole of the end user. The company and product logo may be either stamped or hot melted in the middle of the insert on the top side.

    The fifth style may be a premade orthotic or orthopedic shaped insole made of polyurethane, rubber, EVA, PORON™, urethane or other suitable material. A layer of different types of fabric materials such as hypo-allergenic fabric, anti-fungus, water proof, nylon fabric that comes in different colors and may be utilized in all military footwear and meets all military specifications or other types and styles of fabrics may be adhered with adhesive to the top of the premade orthotic or orthopedic insole. The company and product logo may be either stamped or hot melted in the middle of the insert on the top side.

    The protective material may be placed into the press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the size(s). The protective inserts may also be cut to the shape of the footwear insole by using a laser machine. The sheet of protective material may be placed on top of the cutting table of the laser machine and then the sizes may be added to a computer program of the machine and the machine tells the laser what and how to cut the protective material. After the sheet of protective inserts may be cut out, they may be either placed in a sized insole mold and sprayed or rolled or sprayed with an adhesive and then placed into a sized insole mold and then the orthotic or the orthopedic insole may be placed on top of the adhesive that may be on top of the protective insert.

    Adhesive may also be sprayed or rolled to the bottom of the protective insert. The process of manufacturing the protective insert with an adhesive on the bottom may be that the protective material may be flipped where the bottom may be facing upward. Then an adhesive may be spayed or rolled onto the material and covered with a non-adhesive wax paper or plastic that will not adhere to the adhesive producing a peel and stick concept. Then the sheet of protective material may be sled into the press cutting machine that has sized forged dies in the shape of footwear insoles that may be attached to the top plate of the cutting machine and when the button may be pushed the plate with the sized forged dies comes down cutting the size(s). The insert may come in two precut sizes. One size may be a men's size thirteen that may be trimmed down to any size. The other size may be a men's size sixteen that may be trimmed down to a men's size thirteen and a half. Either size may be trimmed to fit by the end user for 100% protection. The other sizes may be manufactured to be precut to any size. This method would have to be done before the orthotic or the orthopedic insole may be adhered to the top of the protective material insert. This would allow the end user to remove the original insole of the footwear, peel the non-adhesive wax paper or plastic off the bottom of the protective insert and place it onto the inner shoe sole of the footwear and press down. This will allow the protective insert to be coupled to the inner sole of the footwear to reduce slippage and/or movement. The end user could utilize it as a replacement insert for the footwear and be protected from unforeseen dangers of sharp objects penetrating the sole of the footwear injuring the foot sole of the end user.
