The present disclosure relates to systems and methods for generating orthotic device models using simulated patient anatomy. In one implementation, a method comprises receiving images of a body part of a patient; deriving physical measurements from the images; generating anatomy model data of the body part using the physical measurements; and generating orthotic model data based on the anatomy model data, the orthotic model data being representative of an orthotic device.

An orthotic insole comprising top, middle, and bottom layers. The top layer is in contact with a wearer's foot or a wrap of material, the bottom layer is adjacent to an outsole of the shoe, and the middle layer is positioned therebetween. The top layer has substantially the same width and length of the entire insole. The middle layer is a generally j-shaped strip which provides a rearfoot posting within the insole and a cupping effect to a wearer's heel. The middle layer may have a similar overall width as the top layer but may include a shorter length than the top layer such that the middle layer only extends from the heel to approximately the joint of the fifth metatarsal bone. The bottom layer may be more rigid than the other two layers, and may further include a rigid plate. The insole may further include an arch support integrally formed within one or more of the layers or a cushioning layer with one or more cushioning segments on top of the top layer.

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 structure in which complexity of the moving path of the nozzle during forming is suppressed even if the structure has regions with different elasticity and a manufacturing method for a structure that can suppress complexity of the moving path of the nozzle when forming the structure with regions with different elasticity. The structure includes a formed body with a linear structure formed of a linear resin. The formed body includes first and second elastic regions, and the linear resin forming the first elastic region is thinner than the linear resin forming the second elastic region.

A shoe insole assembly for enhancing the odor of a shoe includes an insole that is insertable into a shoe. The insole is comprised of a resiliently compressible material to enhance comfort for a user wearing the shoe. Additionally, the insole is infused with a chemical odor eliminator to reduce odors associated with shoes. The insole is infused with a volatile chemical scent that is released from the insole to enhance the scent of the shoe. A cushion is coupled to the insole and the cushion is comprised of a resiliently compressible material to enhance comfort for the user.

Footwear with vertically lapped nonwoven layers in upper and sole structures for enhanced breathability and moisture wicking is disclosed. Exemplary vertically lapped nonwoven dual layers comprise one or more hydrophobic layers and one or more hydrophilic layers that are adhered to each other by a plurality of methods and are further integrated into the inside of the upper and sole of the footwear so that the hydrophilic layer is in direct contact with the feet. The hydrophilic part of the dual layer wicks sweat or bodily fluid from the wearer into the nonwoven and transports the moisture to the hydrophobic layer for fast evaporation, thus keeping the feet dry. The nonwoven footwear is environmentally friendly as the nonwoven layers can be made of recycled materials and may be fully recyclable.

A foot pain relief device formed as a shoe or boot insert comprising a plurality of removable pieces designed to be selectively removed from the insert to thereby create a hollow portion, indentation, dip, concavity, groove, or impression area of the insert that allows the injured area to be free from impact of any sort while going through its healing process while the user continues daily activities without feeling discomfort or pain from the injured area of the foot.

A woven fabric for promoting heat dissipation covers a wearer's skin when in use, and has two surface layers and an intermediate layer. The two surface layers are disposed at a spaced interval, and include a first surface layer and a second surface layer oriented to the wearer's skin when the woven fabric is in use. The second surface layer has multiple braids disposed parallelly, and each one of the multiple braids is straight. The intermediate layer is formed with multiple monofilaments which are woven between the multiple braids of the second surface layer and the first surface layer. An insole and a clothing which adopt the same are provided as well.

Disclosed herein is a footwear system with tunable flexibility properties and a process of reversibly modifying the flexibility of footwear. In particular, there is described a footwear system comprising at least two items of footwear and at least two footwear flexibility modulators with anisotropic flexibility properties. In use, the footwear system can be reversibly switched from a stiff configuration to a flexible (i.e. less stiff) configuration. Also disclosed is a method of reversibly modulating the flexibility of footwear.

Apparatus and associated methods relate to a footwear liner system including a liner portion to be worn on a foot and a releasably attachable external insole, releasably attachable to an underside of the liner. In an illustrative example, the external insole may be configured to provide arch support for the insole independent of the liner's conformability to the foot. In an illustrative example, the liner is pliable and moldable. In an illustrative example, the external insole includes a stiff arch support that is independently and releasably attachable to the liner. Various embodiments may advantageously provide an economical sports boot liner assembly with user-integratable custom insole.
