The present invention relates to an insole containing one or more cavities, wherein said one or more cavities contain a component capable of a physiochemical reaction, as well as articles of footwear containing the insole and methods of making the insole. The invention also relates to methods of heat transfer between an article of footwear and a foot of a wearer of the article of footwear, the method including priming the insole, wherein the priming initiates the physiochemical reaction.

A strobel for an article of footwear contains ETPU. The article of footwear and a process for manufacturing the article f footwear are also provided.

Under the inventive process, the customised split insole is made by processing manually collected medical data and arch data along with plantar pressure distribution data and foot type data both of which are collected using a computer enabled Plantar Pressure Measuring Device in a first computer and processing these data in a second computer to generate a Projection Data which is expressed in Shore Hardness Value. Then, ranking of the projection data into a zone wise Ranking Index, determining the elasticity of the material to be used for the said Shore Hardness Value, converting the said shore hardness value into Surface Tessellation Language and transmitting the same to a third computer built into a 3D printing machine which selects a suitable material and its elasticity zone wise as per the Shore Hardness Value and 3D prints the same.

An inventive custom made split insole for use by diabetic patients, split into zones for normal and flat foot persons and five zones for high arch foot persons where these splits have projections which are hexagonal or oval in shape and have specific dimensions and specific spacing but are of uniform height and elasticity.

A mold stepped on by a foot includes a seat, a plurality of telescopic rods, an image capturing device and an insole material. The telescopic rods are parallel to each other and are disposed in the seat. The telescopic rods stepped on by the foot generate a plurality of restoring forces, respectively. The image capturing device is disposed on the seat. The telescopic rods are captured by the image capturing device to generate a plurality of three-dimensional data of the telescopic rods. The insole material is disposed below the telescopic rods for molding an insole.

A footwear insole shape is generated by supplying a core reinforced filament having a matrix material impregnating reinforcing strands aligned along the filament, as well as a fill material separately from the core reinforced filament and depositing at least one shell of fill material within an insole shape upon a print bed. The core reinforced filament is deposited to fuse to the fill material within a first reinforcing region formed with respect to the insole shape. A cutter upstream of the nozzle tip cuts the core reinforced filament, and a remainder of the core reinforced filament is deposited to complete the first reinforcing region. A nozzle tip applies pressure to continuously compact the core reinforced filament toward the insole shape as the core reinforced filament is fused to the fill material.

The present invention concerns a novel low-temperature thermoplastic wood-biopolymer composite comprised of small wood particles and a polycaprolactone (PCL) homopolymer for use in medical procedures including orthopedic casting or splinting. The material is made from a thermoplastic composite that softens when heated to approximately 60 C., after which it can be formed directly on the patient. The composite then retains its shape as it cools down. The material is composed of epsilon caprolactone homopolymer reinforced with discontinuous short length wood particles.

The present disclosure provides an intelligent insole module. The intelligent insole module is placed inside an insole for tracking a user's exercise behavior. The intelligent insole module comprises a sensing unit, a wireless unit, a control unit and a power supply unit. The sensing unit detects an exercise information. The wireless unit transmits the exercise information. The control unit is connected to the sensing unit and the wireless unit, and controls the sensing unit and the wireless unit. The power supply unit is connected to the control unit, and supplies electricity to the intelligent insole module. The power supply unit comprises a magnetic charging structure.

An insole that includes grip fabric that has a high coefficient of friction to prevent slippage within a shoe. The insole can include a heel portion that extends from the base and the grip fabric can be applied to at least regions of the heel portion as well.

An insole includes an insole body, a lower pad and a mounting box. The insole body is provided with a bottom surface, a first rear end, and a first front end. The lower pad is provided with a second front end and a second rear end; the second front end is correspondingly stacked with the first front end, the second rear end is correspondingly folded with the read end; the mounting box is fixed in the mounting cavity. The lower pad of the insole is correspondingly stacked with the bottom surface of the insole body, with the stacked design, the insole can be assembled quickly and easily, with fewer assembly procedures.
