A foot protection pad is provided, comprising: a body, a midfoot elastic body and a heel elastic body; wherein, the body is formed with a first elastic material to form a front plantar area, a midfoot area and a heel area; the bottom surface of the midfoot area is formed with a midfoot arch, and opposite sides are formed with a concave arc surface of the inner arch and the concave arc surface of the outer arch; a recession is formed on the body of the heel area, and the opposite two sides of the recession are formed with a concave arc surface of the inner arch and a concave arc surface of the outer arch, and the rear end is formed with a heel concave arc surface; the midfoot elastic body and the heel elastic body are formed with a second elastic material and respectively combined with the body.

A sole board for an article of footwear includes a plate that has a forefoot region, a midfoot region, and a heel region. The sole board includes a channel disposed in a top surface of the plate in the forefoot region. The channel extends from a lateral edge of the plate to a medial edge of the plate. A characteristic of the channel at the lateral and medial edges of the plate is different than the characteristic of the channel at a middle of the channel.

The woven fabric of the invention is designed to be integrated into shoe soles, in order to produce safety footwear that provides a high level of protection and meets safety requirements in terms of puncture protection. For this purpose, the fabric consists of at least 60% high-tenacity yarns, said yarns having a titer of between 80 and 280 tex, and each yarn being formed by filaments having a fineness of between 1 and 6 Dtex. Thus, the fabric is formed by between 1 and 10 warps interwoven with between 5 and 10 wefts and produced by means of weaving, in order to produce a very compact fabric having high mechanical strength.

The present invention describes a shaped footwear device intended to be used as a supportive insole or orthotic and a system and methods for making the same. The footwear device includes a top foam layer, a light-cured composite material layer, and a bottom textile layer. The footwear device is created by conforming a pre-cured insole assembly to the plantar surface of a foot or foot mold and then exposing the pre-cured insole assembly to light to create a shaped footwear device with a light-cured composite material support plate.

Waterproof, breathable socks, booties, shoe inserts, and footwear assemblies containing the shoe inserts are provided. The booties and shoe inserts include a laminate of a seamless ePTFE membrane and at least one textile. The bootie is conformable over a range of sizes and shoe shapes, and may be shaped to fit numerous sizes and shapes of asymmetrical shoe lasts. The bootie may shrink to fit, or, alternatively, be stretched to fit, an asymmetrical last having a desired size to form a shoe insert. Such a conformable bootie eliminates the need to have multiple sizes of shoe inserts correlating to particular shoe sizes. In embodiments where the ePTFE is seamless and continuous, the shoe insert eliminates the need for a waterproof seam tape, which is conventionally used to make shoe inserts waterproof. Methods of forming the socks, booties, and shoe inserts are also provided

Provided herein are embodiments of a shoe component. The shoe component may include a toebox, an insole, an adhesive membrane, a thermal-resistant insert, a midsole, and an outsole. The insert may further include a footbed. The footbed may include an upper surface and a bottom surface. The insert may further include an upper laminate on the upper surface of the footbed and a lower laminate on the bottom surface of the footbed.

The new apparatus is an orthopedic foot bed created using multiple materials to provide maximum comfort for an individual. The apparatus is composed of a flexible material such as, for example, memory foam on top of another material such as an impact absorbing material and an arch-support foot bed made of, for example, antimicrobial energy returning foam, with the entire apparatus covered in a stretchy suede textile in one embodiment.

A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.

A copolymer may include ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. Embodiments may also be directed to curable polymer compositions, expandable polymer compositions, articles, cured articles, and expanded articles formed from or including such copolymers of ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. A process for producing an ethylene vinyl acetate copolymer may include
