 Composite footwear insoleThe Patent Description & Claims data below is from USPTO Patent Application 20070180632. Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This application is a divisional application from co-pending application Ser. No. 11/146,841 entitled MULTIPIECE FOOTWEAR INSOLE filed on Jun. 7, 2005 for which the U.S. Patent Office has issued a notice of allowability to the same sole inventor named in this application. The specification of the pending application is incorporated by reference into this document. FIELD OF TECHNOLOGY [0002] The composite footwear insole disclosed, shown, and claimed in this document pertains generally to footwear. More particularly, the new and useful composite footwear insole provides an insole that relieves pain suffered by footwear users whose footwear does not include the composite footwear insole disclosed, shown, and claimed in this document. BACKGROUND [0003] Diabetes mellitus is a chronic disease that affects the lives of millions of people in the United States and around the World. Many diabetics develop a serious foot conditions at some time during their lives, which in some cases require toe amputations or even amputations of the entire foot. High blood sugar levels also affect the body's immune system and delays wound healing. [0004] Neuropathy is an impairment that affects about half of those with diabetes. It causes loss of feeling in feet, which increases the risk of undetected injury. Diabetics suffering from neuropathy can unknowingly develop minor cuts or scrapes, blisters, or pressure sores due to the feeling insensitivity. If such minor injuries are left untreated or fail to heal, complications may lead to ulceration, infection, and gangrene. In fact, diabetic foot complications are the most common cause of non-traumatic lower extremity amputations in the United States. The risk of lower extremity amputation has been estimated to be about 15 to 46 times higher in diabetics than in non-diabetics. Importantly, the majority of diabetic foot complications begin with the formation of skin ulcers on the bottom of the foot. [0005] Specially designed footwear for diabetics as well as other orthopedic devices can reduce the risk of many foot complications, such as the formation of calluses, foot ulcers, poor circulation, decreased resistance to infection, foot deformities, and neuropathy, all of which are especially problematic for diabetics. [0006] Custom orthopedic foot wear for diabetics often has a relatively rigid, but resilient base comprising a heel portion and an arch portion contoured to fit the plantar, or bottom surface, of a foot. Unfortunately, most customized prescription orthopedic footwear and/or footwear devices for diabetics require the preparation of molds for the feet that in turn require subsequent manufacturing of footwear and/or devices causing significant delay between the measuring of feet for an orthopedic shoe or device, and the arrival of the new customized device such as insoles as well as footwear. The custom insoles are generally created from hard plastics by making a mold based on detailed foot measurements. The mold is modified to provide prescribed corrections by a podiatrist. Custom orthopedic footwear may also be unattractive. The resulting footwear will not be as versatile as insoles insertable within ordinary shoes and other footwear. [0007] Conventional footwear inserts or soles consist of materials such as rigid plastic and/or elastomeric foam with an impact cushioning foam layer or space filler. They provide insufficient foot protection and/or do not address the different needs of the various areas of the foot, which can be unique to wearers. Such insoles often do not provide enough protection or support for proper biomechanical functions of a foot, particularly in the rear foot area, and in the arch areas of a foot. Conventional insoles typically do not hold a wearer's heel in place or provide arch support, or allow movement of the foot such as in the toe area that allows toes to slide and move. Thus, conventional inserts and soles are often ineffective in preventing or alleviating foot conditions experienced by diabetics and other persons with foot problems. [0008] Special footwear and/or footwear components and devices are considered significant in preventing the problems of diabetics and others. It is also believed that many foot and toe complications of non-diabetics could be prevented through the use of the composite footwear insole disclosed, illustrated, and claimed in this document. The composite footwear insole has sections that are for a variety of foot shapes and that can be customized for a variety of wearers and wear requirements. One or more of the sections may have different cushioning and/or surface characteristics. SUMMARY [0009] It will become apparent to one skilled in the art that the claimed subject matter as a whole, including the structure of the apparatus, and the cooperation of the elements of the apparatus, combine to result in a number of unexpected advantages and utilities. The structure and co-operation of structure of the composite footwear insole will become apparent to those skilled in the art when read in conjunction with the following description, drawing figures, and appended claims. [0010] The foregoing has outlined broadly the more important features of the invention to better understand the detailed description that follows, and to better understand the contributions to the art. The composite footwear insole is not limited in application to the details of construction, and to the arrangements of the components, provided in the following description or drawing figures, but is capable of other embodiments, and of being practiced and carried out in various ways. The phraseology and terminology employed in this disclosure are for purpose of description, and therefore should not be regarded as limiting. [0011] As those skilled in the art will appreciate, the conception on which this disclosure is based readily may be used as a basis for designing other structures, methods, and system. The claims, therefore, include equivalent constructions. Further, the abstract associated with this disclosure is intended neither to define the composite footwear insole, which is measured by the claims, nor intended to limit the scope of the claims. [0012] The novel features of the composite footwear insole are best understood from the accompanying drawing, considered in connection with the accompanying description of the drawing, in which similar reference characters refer to similar parts, and in which: DRAWINGS [0013] FIG. 1 is a top side view of an insole of this invention for the left foot in an assembled state; [0014] FIG. 1A is a view of an insole of FIG. 1 showing the undersides of the sections; [0015] FIG. 2 is a bottom view of the bottom layer of the insole of FIG. 1; [0016] FIG. 2A shows the top side of the bottom layer of the FIG. 2; [0017] FIG. 3 is a right side view of an insole for the left foot, with the sections of the insole unassembled, but in their respective positions; [0018] FIG. 3A is a left side view of the insole of FIG. 3, with the sections of the insole in their respective positions, unassembled; [0019] FIG. 4 is a right side view of the insole of FIGS. 3-3A in an assembled state; [0020] FIG. 4A is a left side view of the of the insole of FIG. 4 in use in footwear; Continue reading...
