A footwear insole includes a base layer configured to overlie a sole of an article of footwear, a moisture permeable layer overlying the base layer, and an airgap structure captured between the base layer and the moisture permeable layer. Perimetric edges of the base layer, the airgap structure and the moisture permeable layer are aligned to form an insole perimetric edge.

A multilayer orthotic/orthosis has a cover layer, a shell layer and a posting layer. The shell layer is formed of a thermoplastic having a moldable temperature. The rigidity of the shell layer, and in particular the rigidity of the thermoplastic is chosen to be of a magnitude to support the portion of the individual at temperatures below the moldable temperature. The shell layer, preferably the thermoplastic, has a flexibility above the moldable temperature to mold the shell layer into a shape to support the portion of the individual. The shell layer has two layers of woven polyester fibers (“scrim”) on the top and bottom. The scrim gives the plastic strength and prevents it from stretching excessively when molding. These unique properties make the material well suited for stacking multiple layers without having excessive bulking of material top lines. Both sides of the shell layer are coated with a layer of hot melt cement/glue/adhesive for easy attachment of various layers or other materials. One side of the shell layer is connected to one side of the cover layer. A posting layer is arranged on a side of the shell layer diametrically opposite the cover layer, and provides support for the orthotic/orthosis in order to prevent rocking, especially when the orthotic/orthosis is for the foot of the individual.

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.

The article of footwear for grounding the human body to earth includes an upper portion; a sole having an outer sole face distal from a user and an inner sole face proximate to the user; one or more electrically conductive portions which extend through the sole from the outer sole face to the inner sole face; and an electrically conductive layer which extends over a portion of the inner sole face and being configured to make conductive contact with the foot of the human body. The sole includes a blade portion.

Systems and methods for supporting an object to be printed in an additive manufacturing process are disclosed. Support structures (202, 302, 402, 502, 602) are prefabricated and positioned in the build area of a 3D printing device prior to printing the 3D object. When the object has been printed, the support is removed and can be reused to print another object by repositioning the support structure in the building area of the additive manufacturing device.

Aspects hereof relate to a multi-part mold assembly for use in manufacturing articles. The mold assembly provides for contouring, shaping and cutting materials to form articles via a continuous single processing operation. The mold assembly includes an upper mold portion with a three-dimensional contouring/shaping portion and a first cutting edge, a lower mold portion with a three-dimensional contouring/shaping portion and a second cutting edge, and a base portion into which the lower mold portion may retract during use. Upon application of a first force, the upper and lower mold portions cooperate to contour/shape a material from which an article is to be formed. Upon application of a second force greater than the first, the first cutting edge and the second cutting edge interact to shear the material that extends beyond the respective cutting edges. The result is an article that is contoured, shaped and cut/trimmed utilizing a single processing operation.

The present invention relates to a footwear liner insert configured to absorb sweat and dirt while simultaneously providing a pleasant fragrance emitting from the footwear liner insert. The liner having an adhesive layer for releasably attaching to an insole of a footwear and an elastomeric nonwoven layer for absorbing sweat. The footwear liner insert is infused with natural essential oils for releasing fragrance upon compression of the footwear liner insert. In some embodiments, the liner is disposable and can be detached after use by pulling the adhesive layer from the insole of the footwear. The liner is designed to meet and fit in different types of footwears and is configured in different designs and sizes. The liner provides adequate grip and friction for smooth walking and running for a user of the liner.

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.

A sockliner for a shoe may be formed to include an integral fabric skirt. The fabric skirt may remain loose from the sockliner along at least a portion of the periphery of the sockliner. The loose periphery of the fabric skirt may be used to join the sockliner to other shoe components, as in a strobel-type seam.

Systems and methods of determining spinal column and or leg length abnormalities includes taking digital photographs of multiple data points along the length of the person's spine and legs, and sending the photographs to a computer with a processor programmed with software that analyzes the photographs to determine leg length and spinal column length and spinal column curvature. The data regarding the leg length and curvature is sent to a medical professional for diagnosis and treatment of the patient.
