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.

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 foot engagement device includes a generally U-shaped portion having an inner edge, an outer wall, and a tapered upper surface extending from the inner edge to the outer wall. The upper surface tapers between 1 degree and 45 degrees from the inner edge to the outer wall.

Footwear includes structural features that may provide one or more of the following features or functions: (a) help “lock” the wearer to the ground under torsional forces induced in the leg/foot (e.g., by a golf swing or other activities); (b) help provide stable support, e.g., at the medial heel and/or lateral forefoot areas; (c) help support and prevent undesired distortion of the footwear upper, e.g., when torsional forces are applied; and/or (d) help provide a very stable and secure feel and fit by securing across the instep portion of the foot, e.g., in a forward lateral-to-rear medial direction (e.g., between medial heel and lateral forefoot sidewall supports).

A shoe sole includes a rear bottom surface part and a toe portion. The rear bottom surface part is formed to extend from a rearfoot portion to a midfoot portion and, when the shoe sole is placed on a flat virtual surface, the rear bottom surface part is in contact with the virtual surface. A height of the toe portion from the virtual surface is set to 170% or greater and 250% or less with respect to a thickness dimension in the rear bottom surface part.

At least one embodiment of the present subject matter is directed towards an apparel. The apparel in accordance with one embodiment may be a sock. The apparel in accordance with another embodiment may be a wearable insole. The apparel comprises a plurality of cushions configured on a base of the apparel at various locations to relieve effects of one or more feet ailments. The apparel comprises a first cushion for supporting a heel of the user, a second cushion for supporting a longitudinal arch of the user, a third cushion for supporting a first metatarsal of the foot, and a fourth cushion for supporting the toes of the user. The first, second, third, and fourth cushions may be made of at least one of a thicker yarn, a foam material, and a gel material.

A sole structure for an article of footwear includes a chassis including a footbed having an interior surface and an outer surface formed on an opposite side from the interior surface, the interior surface defining one or more sockets. The sole structure also includes one or more haptic elements each having a bottom surface received within a respective one of the one or more sockets and a top surface protruding from the interior surface of the chassis, each of the one or more haptic elements having a different hardness than the footbed.

A spine for an article of footwear includes a base extending from a first end to a second end. The spine also includes a sidewall extending transversely from the base from the first end to the second end. The sidewall has a plurality of sidewall supports including a forefoot sidewall support at the first end, a heel sidewall support at the second end, and a mid-foot sidewall support disposed between the first end and the second end and defining a maximum height of the sidewall.

The present invention is directed toward an article of footwear having a sole structure effective to increase traction on a support surface. The article of footwear includes a sole structure comprising a first sole structure and a second sole structure. The article of footwear includes a forefoot region, midfoot region, and hindfoot region. The first sole structure is disposed in the forefoot and hindfoot regions. The second sole structure is disposed in the midfoot region. An extension of the second sole structure that extends through the forefoot region is substantially covered by the first sole structure. A plurality of lugs extend downwardly from the bottom surface of the first sole structure. At least one lug extends downwardly from the extension of the second sole structure through the first sole structure. The first sole structure and the second sole structure have different durometers.

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.
