Multilayer insoles made of several layers of polymeric materials and used for insertion into footwear, for example, for hygienic and orthopedic purposes. Multilayer insoles having increased manufacturability, absorption properties and low cost of environmentally friendly raw materials obtained from renewable sources.

An insole for offloading injuries on an area of a plantar surface of a patient's foot includes a body having a shape corresponding to the plantar surface of the patient's foot including a top surface and a bottom surface; and at least one supportive, deformable, deflatable bubble chamber. The at least one bubble chamber extends from the top surface of the body. The at least one bubble chamber is configured to be deflated to relieve pressure on the plantar surface of the patient's foot. A kit including the insole and an article of footwear including a sole, an upper connected about a periphery of the sole defining an interior of the article of footwear, and the insole positioned in the interior of the article, are also provided.

The invention relates to an insole for a footwear including a non-moldable base layer (310) having an arch supporting portion (312) adapted to support an arch of a foot; and a moldable layer (330) overlaying the non-moldable base layer (310), such that the moldable layer (330) is adapted to be molded to conform to the arch of the foot. The invention also relates to a footwear comprising the insole.

A wearable container containing a composite which has an alternating pattern containing groupings of woven fabric and groupings of biaxially oriented thermoplastic films. The composite has a thickness of less than about 5 mm. Each grouping of woven fabric contains at least one woven fabric layer, each woven fabric layer containing tape elements having a base layer of a strain oriented olefin polymer disposed between covering layers of a heat fusible olefin polymer. Each grouping of biaxially oriented thermoplastic films contain at least one biaxially oriented thermoplastic film which has a core layer of thermoplastic disposed between covering layers of a thermoplastic able to bond to polypropylene.

A footwear assembly having an upper configured to receive a foot and a sole assembly integrally connected to the upper. The sole assembly includes an outsole and a midsole coupled between the upper and the outsole. The sole assembly also includes a footwear insert coupled to the midsole having anisotropic and anti-puncture properties so as to provide protection, support, and stability to the foot of a wearer of the footwear assembly while still allowing for flexibility. The footwear insert is formed from a soft, dorsal layer having woven fabric, a hard, plantar layer formed from a fiber reinforced composite material bonded to the dorsal layer, and an interfacing polymer layer interposed between the dorsal and plantar layers and used to bond the two layers together. The layered arrangement has a high resistance to bending in a first direction and a low resistance to bending in an opposing second direction.

A footwear assembly with an insole assembly having a heel insole board above a midsole and a bifit insole board, which has a heel portion that is stiffer than a forefoot portion. The bottom edge flanges of the upper wrap around the sides of the bifit insole board's heel portion and arch portion rearward of an attachment transition area. At least a portion of the flanges are adhered between the bifit insole board and the heel insole board. The upper's flanges are positioned adjacent to sides of the bifit insole board's forefoot portion and arch portion forward of the attachment transition area without wrapping under the bifit insole board. The upper's flanges are stitched to a top or edge of the bifit insole board's forefoot portion and arch portion forward of the attachment transition area.

A multi-layered orthopedic insole has at least four layers. The first layer is leather, the second layer is molded high-density recycled latex foam, the third layer is a molded, rigid density cork-EVA (Ethylene-Vinyl Acetate) footbed, and the fourth or bottom layer is moleskin or moleskin coated to provide a natural grip for gripping a shoe insole. The different layers are fused to form the orthopedic insole of the present invention. The third layer of the multi-layered insole is generally thicker than the other layers and includes sidewalls covered in a leather wrap. The multi-layered orthopedic insole is specifically designed to provide comfort and support to a user's foot using the specified materials, shapes, and contours.

A method for obtaining foot analysis data for a manufacture of an insole, comprising: subjecting at least one foot of a person to a three-dimensional (3D) scanning apparatus (200); performing a first 3D scanning of a shape of the foot, wherein the person is standing in a straight position (202); performing a second 3D scanning of the shape of said foot, wherein the person provides excess pressure on the foot by squatting (204); and performing a third 3D scanning of the shape of said foot, wherein toes of the foot are lifted up (206).

An insole and/or outsole for a shoe such as an athletic shoe or cleat that includes a multilayer channeled assembly designed at preventing the transfer of heat from extremely hot ground surfaces, most notably synthetic turf, to the foot. In one embodiment, the insole includes a channeled layer of solid material with a very low thermal conductivity, preferably silicon or cork, as the base material beneath a layer of heat resistant felt preferably made of oxidized polyacrylonitrile fibers. The channeling in the base layer allows for air pockets to be created within the insole itself that makes the heat resistant felt more resistant to (i.e., more efficient at preventing) the transfer of heat. In another embodiment, the outsole for a shoe such as an athletic shoe or cleat includes a base layer of channeled solid material with low thermal conductivity, preferably silicon, cork, or polystyrene, below a layer of heat resistant felt preferably made of oxidized polyacrylonitrile fibers. This assembly is encased within a solid plastic mold that extends up to the base of the upper of the shoe or cleat and allows for little or no pressure to be put on the assembly itself. The studs for the cleats are preferably molded out of the plastic encasing itself.
