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.

This invention relates to a shoe insole comprising an inner sole having one or more of a support portion in the rearfoot exterior quadrant, a cushioning portion in the forefoot interior quadrant, a cushioning portion that extends from the forefoot interior quadrant to the forefoot exterior quadrant, and a cushioning portion in the rearfoot interior quadrant and the rearfoot exterior quadrant. Methods of making, using, and positioning the disclosed shoe insole and the components thereof are also described. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The present invention is footwear having a convex shaped outsole with opposing wedge shaped configurations in the bottom of the front sole section and the back sole section which provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The present invention is also footwear convex shaped in the longitudinal direction with a split sole having opposing wedge shaped configurations in the bottom of the front sole section and the back sole section that provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The invention further includes footwear having at least one pair of wedges on the outsole which provide footwear having improved arch support. The invention is also footwear with a flexible, elastic, member between the front sole section and the back sole section of the sole.

Described are soles for a shoe, in particular for a sports shoe, with a midsole. The midsole includes a first sole region, which includes particle foam. The midsole further includes a deformation region within the midsole, wherein the deformation region has a volume greater than that of a single expanded particle and is positioned so that it allows a sideward deformation of the material of the first sole region under a pressure load on the sole.

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

The midsole structure for an athletic shoe includes a midsole body made of foamed resin, and a sheet composite extending at least from the ball of the foot portion to the toe portion in the midsole body and comprising a plurality of foamed rubber sheets that are overlapped and shifted in the longitudinal direction. The sheet composite comprises a single sheet at the toe portion and a plurality of sheets at the ball of the foot portion.

A damping sole includes support zones with a main surface that have a relative stiffness or hardness lower than that of the other zones, the support zones being positioned under the load-bearing protuberances of the foot. The support zones are delimited by oblique lateral faces that are inclined towards the lower main surface of the sole at an inclination angle (A) and are disposed such that, at rest, they come to bear obliquely against the peripheral surface of the dermal part of the corresponding load-bearing protuberance of the foot. In this way, a compromise is reached between the need for impact damping and the need for foot stability in a shoe, while ensuring satisfactory comfort.

The invention relates to an insole structure with decompression. It comprises an insole main body, and a guiding thin pad portion and a rear thin pad portion disposed on the insole main body, wherein the guiding thin pad portion provides capacity for an area given from metatarsophalangeal joints connected with a first phalanx and a first metatarsal till a fifth phalanx and a fifth metatarsal of the anterior sole, and the rear thin pad portion provides capacity for the calcaneus and have the first metatarsophalangeal joint stay at the lowest place while stepping.

A convertible shoe may include a sole and a plurality of interchangeable heel portions, each selectively attachable to the sole. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole. The heel receiver may include a fixed hook and a movable hook, with the movable hook being operable by an actuator coupled to a bottom surface of the sole. In some examples, an upper is secured to the sole of the shoe by one or more clamping plates. In some examples, the sole of the shoe is configured to be biased into a default bend corresponding to a high-heeled state even when a low heel is attached to the heel receiver.
