(20) The shoe cover apparatus 22 includes a shoe cover portion 24 attachable and removable for covering a top portion 14 of a shoe 12 but not covering a bottom portion 13 of sole 16 of the shoe 12. The shoe cover portion 24 comprises a waterproof and/or a water resistant portion. Plural first attachment portions 26 at a bottom end 28 of the shoe cover portion 24 attach the shoe cover portion 24 to the top portion 14 of the shoe 12. Selected ones of the plural first attachment portions 26 are specifically sized and shaped to attach onto pre-existing features 18, 18 (e.g., laces, ridges, grooves, etc.) of the top portion 14 of the shoe 12. A shoe cover connection portion 30 at a top end 32 of the shoe cover portion 24 is attachable and removable to a portion (e.g., an ankle, leg, etc.) of a person 34 wearing the shoe 12. The shoe cover connection portion 30 includes a shoe cover attachment portion 36. The shoe cover connection portion 30 comprises an insect repellant portion. Plural second attachment portions 38 attached to the bottom end 28 of the shoe cover portion 24 include apparatus for attaching the shoe cover portion 12 to the sole 16 of the shoe 12. Selected ones of the plural second attachments portions 38 are specifically sized and shaped to attach onto and through pre-existing features 42, 42 (FIG. 3) of the sole portion 16 of the shoe 12. However, present invention is not limited to the components described and more, fewer and other component of the shoe cover can be used to practice the invention.

(21) The shoe cover portion 24 includes a fabric comprising: synthetic fiber fabrics, natural fiber fabrics, composite materials fabrics, hard plastics, soft plastics and combinations thereof. However, the present invention is not limited to these shoe covering portions 24 and more, fewer and/or other shoe cover portions can be used to practice the invention.

(22) In one embodiment, the shoe cover portion 24 comprises, various synthetic fiber fabrics (e.g., NYLON, etc.), natural fiber fabrics (e.g., animal, cotton, wool, silk, etc.), composite materials, hard and soft plastics, and/or propylene based materials, etc. However, the present invention is not limited to these shoe covering portions 24 and more fewer and/or other shoe cover portions can be used to practice the invention.

(23) Natural fibers are a class of hair-like materials that are continuous filaments or are in discrete elongated pieces, similar to pieces of thread. They can be spun into filaments, thread, or rope. They can be used as a component of composite materials. They can also be matted into sheets to make products. Natural fiber which comprise animal and plant fibers. The most used plant fibers are paper, cotton, flax and hemp, although sisal, jute, kenaf, bamboo and coconut are also widely used. Animal fibers generally comprise proteins such as collagen, keratin and fibroin; examples include silk, sinew, wool, catgut, angora, mohair and alpaca, etc.

(24) Some examples of synthetic fabrics are POLYESTER, ACRYLIC, NYLON, RAYON, ACETATE, SPANDEX, LASTEX and KEVLAR. Synthetic fibers are made by the joining of monomers into polymers, by the process of polymerization. A synthetic fiber, when magnified, looks like plastic spun together. The fabric is made from chemically produced fibers. The chemicals used to make the fibers are sodium hydroxide and carbon disulphide which are derived from coal, oil, or natural gas. The chemicals are in liquid form and are forced through tiny holes called spinnerets. As the liquid comes out of the spinnerets and into the air, it cools and forms into tiny threads. Dyes are added to these threads before they are woven together to make the fabric.

(25) In one embodiment, the shoe cover portion 24 is created from a rigid plastic including Polyetherimide, Polyimide other thermosetting polyimides, other plastics and/or composite materials. The rigid plastics are poured, injection molded, pultruded, extruded, etc. However, the present invention is not limited to these materials and other materials can be used to practice the invention.

(26) Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Polyether ether ketone (PEEK) is a colorless organic polymer thermoplastic Relative to PEEK, PEI is cheaper, but less temperature-resistant and lower in impact strength.

(27) For example, commercially, ULTEM is a family of PEI products manufactured by SABIC. ULTEM resins are used in medical and chemical instrumentation due to their heat resistance, solvent resistance and flame resistance.

(28) Polyimide (PI) is a polymer of imide monomers. Such imide monomers include pyromellitic dianhydride and 4,4-oxydianiline and others. Polyimide materials are lightweight, flexible, resistant to heat and chemicals. Polyimide parts are not affected by commonly used solvents and oils, including hydrocarbons, esters, ethers, alcohols and freons. They also resist weak acids.

(29) Thermosetting polyimides are known for thermal stability, good chemical resistance, excellent mechanical properties. Normal operating temperatures for such polymides range from cryogenic with temperatures below about 238 F. (150 C.) to those exceeding about 500 F. (260 C.).

(30) In one embodiment, the shoe cover portion 24 is created from composite material fabric. Composite materials are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic scale within the finished structure. Common polymer-based composite materials, include at least two parts, a substrate (e.g., fibers, etc.) and a resin. However, the present invention is not limited to these plastic materials and other materials can be used to practice the invention.

(31) The composite materials include Fiber-reinforced polymers (FRP) including thermoplastic composites, short fiber thermoplastics, long fiber thermoplastics or long fiber-reinforced thermoplastics. There are numerous thermoset composites, but advanced systems usually incorporate aramid fiber and carbon fiber in an epoxy resin matrix. The composite materials also include carbon/carbon composite materials with carbon fibers and a silicon carbide matrix. However, the present invention is not limited to these composite materials and other materials can be used to practice the invention.

(32) In one embodiment the shoe cover portion 24 is constructed from flexible plastics including, but not limited to, PolyVinyl Chloride (PVC) polyethylene, polypropylene, very low-density polyethylene (VLDPE), linear low-density polyethylene (LLDPE) Flexible polypropylene (FPP), Ethylene interpolymer alloy (EIA), EPDM (ethylene propylene diene monomer), composite materials and/or other flexible materials. However, the present invention is not limited to these materials and other materials can be used to practice the invention.

(33) Polyvinyl chloride (PVC) is durable, cheap, and easily worked into membranes. Polyvinyl chloride is produced by polymerization of a monomer, vinyl chloride (VCM). PVC's are relatively low cost, biological and chemical resistance and very workable into membranes.

(34) Very low-density polyethylene (VLDPE) and linear low-density polyethylene (LLDPE) overcome the shortcomings of other polyethylenes (e.g., high density polyethylene (HDPE), etc. in terms of flexibility. These are less crystalline forms of polyethylene which result in increased flexibility and a membrane less conducive to brittle stress cracking.

(35) Flexible polypropylene (FPP) is produced in both unreinforced (PPU) and reinforced (PPR) form to provide a choice in terms of tensile behavior.

(36) Ethylene interpolymer alloy (EIA) is an alloy of PVC resin with a special ethylene interpolymer that results in a flexible plastic-free material. EIA geomembranes maintain the advantages of PVC but have a high degree of durability and chemical resistance.

(37) EPDM (ethylene propylene diene monomer) was developed from butyl rubber and exhibits excellent elongation characteristics.

(38) However, the present invention is not limited to these materials and other materials can be used to practice the invention.

(39) In one embodiment, the shoe cover portion 24 includes Polyurethane coated CORDURA NYLON.

(40) CORDURA is the brand name for a collection of fabrics used in a wide array of products including luggage, backpacks, pants, military wear and performance apparel. CORDURA fabrics are known for their durability and resistance to abrasions, tears and scuffs. CORDURA fabrics are made using yarns or fibers. Fabrics can be made using 100% synthetic fiber or in blends with cotton or other natural fibers.

(41) NYLON is a generic designation for a family of synthetic polymers known generically as aliphatic polyamides. Nylon is one of the most commonly used polymers. Key representatives are nylon-6,6 nylon-6; nylon-6,9; nylon-6,10; nylon-6,12; nylon-11; nylon-12 and nylon-4,6.

(42) However, the present invention is not limited to these materials and other materials can be used to practice the invention.

(43) In one embodiment, the shoe cover portion 24 includes waterproof and/or water resistance breathable fabrics and/or fabrics coated with a waterproof and/or resistant proof coating. In such embodiments, the waterproof and/or water resistant fabrics are coated with a waterproofing and/or water resistant material after selecting of a desired fabric and/or include waterproof and/or moisture proof fabrics created during a manufacturing process.

(44) Waterproof fabrics are fabrics that are inherently, or have been treated to become, resistant to penetration by water and wetting. The term waterproof refers to conformance to a governing specification and specific conditions of a laboratory test method. They are natural or synthetic fabrics that are laminated to or coated with a waterproofing material such as rubber, polyvinyl chloride (PVC), polyurethane (PIT), silicone elastomer, fluoropolymers, wax, etc. during a manufacturing process. However, the present invention is not limited to such embodiments and other waterproof fabrics and/or coatings can be used to practice the invention.

(45) In contrast, water resistant or water repellant fabrics are coated with a compound (e.g., Durable Water Repellant (DWR), etc.) that is resistant but not impervious to penetration by water. Water-resistant fabrics will often bead up water, forming drops on the surface. Water-resistant fabrics will provide protection from limited precipitation, but may not stand up to complete submersion in a water. Though water can saturate the fabric with harsh exposure, a water-resistant treatment will prevent moisture from seeping through the fabric.

(46) DWR is a coating added to fabrics at the factory to make them water-resistant (or hydrophobic). Most factory-applied treatments are fluoropolymer based. Durable water repellents are commonly used in conjunction with waterproof breathable fabrics such as GORE-TEX to prevent the outer layer of fabric from becoming saturated with water. This saturation, called wetting out, can reduce the fabric's breathability (moisture transport through the breathable membrane) and let water through. As the DWR wears off over time, re-treatment is recommended when necessary. Many spray-on and wash-in products for treatment of non-waterproof garments and re-treatment of proofed garments losing their water-repellency are available from sources of sporting apparel. Sprays are made by GRANGERS, NIKWAX, MCNETT, TREK7, and others. Older methods for factory application of DWR treatments involve applying a solution of a chemical onto the surface of the fabric by spraying or dipping. More recently the chemistry is applied in the vapor phase using Chemical Vapor Deposition (CVD) machinery.

(47) Waterproof and/or water resistant breathable fabrics resist liquid water passing through, but allow water vapor to pass through. Their ability to block out rain and snow while allowing vapor from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing and other applications. In another embodiment, the waterproof and/or water resistant proof fabrics include non-breathable waterproof and/or water resistant fabrics. However, the present invention is not limited to such embodiments and other breathable and/or non-breathable waterproof/water resistant fabrics and/or coatings can be used to practice the invention.

(48) In one embodiment, the shoe cover portion 24 further includes an insect repellant fabric and/or insect repellant coating as is described for the shoe cover connection portion 30. In another embodiment, the shoe cover portion 24 includes only the insect repellant fabric and does not include the waterproof and/or moisture proof breathable fabrics In another embodiment, selected portions of the shoe cover portion 24 are coated with and/or include waterproof and/or moisture proof fabric and selected other portions include insect proof fabric and/or coated with an insect repellent. However, the present invention is not limited to these embodiments and various combinations of coated waterproof, coated insect proof and/or insect repellent fabrics and/or water resistant and or waterproof fabrics can be used to practice the invention.

(49) The plural first attachment portions 26 at the bottom end 28 of the shoe cover portion 24 attach the shoe cover portion 24 to the top portion 14 of the shoe 12. Selected ones of the plural first attachment portions 26 are specifically sized and shaped to attach onto pre-existing features 18, 18 18 (e.g., laces, ridges, grooves, etc.) of the top portion 16 of the shoe 12. The pre-existing features 18, 18 18 are exemplary only and the present invention is not limited to a size, shape, etc. of the illustrated pre-existing features.
