Designs and compositions of insoles for footwear are described herein. The insoles may be customized for a given foot. In some examples, the insole (100) includes a base comprising a variable thickness component (205), a directional stiffness component, a stability component, and a reinforcement component. The base may be a single composition that is manufactured using additive manufacturing techniques.

Systems and methods are described for a shoe sole for relieving pressure from a wearer's metatarsal heads. In one aspect, a shoe sole comprises a shoe outer sole comprising a shaft region, a ball region, and a toe region. The shaft region underlies metatarsal shafts of the wearer and comprises a first lower surface, the ball region underlies metatarsal heads of the wearer and comprises a second lower surface, and the toe region underlies phalanges of the wearer and comprises a third lower surface. The second lower surface is raised relative to the first lower surface and the third lower surface.

An orthotic footwear system including a removable outsole, a removable reinforced hollow midsole attached to the top of the outsole, and a removable insole attached to the top of the midsole. A removable metatarsal pad can be attached to the top of the insole, and removable support inserts can be attached around the insole for additional support of problematic areas. Support inserts can be used to support the arch area, the heel area, or both. Each of the removable parts can be interchanged with parts of the same type having different ergonomic characteristics. The user can change the parts of the orthotic to suit their needs. Further, the support inserts can be used apart from the rest of the system, with any insole configured to receive them.

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 plate for an article of footwear having a sole structure includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use.

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.

Footwear may comprise customizable support plates. Methods for customizing footwear comprising a support plate may comprise applying heat to the footwear article to raise a temperature of the support plate to less than the melt temperature of the composition of the support plate such that the support plate becomes non-rigid in a first state, applying force to the support plate in the first state to customize a shape of the support plate, allowing the footwear to cool such that the support plate is at a second state having a higher rigidity than the first state.

In general, certain embodiments of the present disclosure provide an augmented heel cup protective insert device for shoes. The insert device includes a posterior segment corresponding to the curvature of a heel of a shoe. The device also includes a medial wing, a medial parabolic formation that extends in a direction from top to bottom of the device, an inferior segment, and an angulated segment to meet the beginning of the edge of the heel on the medial side of the shoe.
