In at least some embodiments, an orthotic footbed assembly includes a three-dimensional footbed that closely approximates a size and configuration of a particular foot and at least one orthotic feature additively coupled to the three-dimensional footbed. In at least some other embodiments, a method of making the orthotic footbed assembly includes direct printing of orthotic features onto a 3-D footbed. Another method includes indirect printing of orthotic features and applying these features onto to a 3-D footbed. And yet another method includes direct printing of orthotic features onto a 2-D blank footbed and then conducting a three-dimensional forming operation to make the orthotic footbed assembly.

The present invention is intended for use in the high/superhigh-heel shoes. The support surface (6) of the suggested high-heel shoe comprises a practically horizontal portion (7), the distance of which to the lowest point of the support surface is at least 5 mm. This portion is located in the zone of the maximum distance of the external part of a foot from the longitudinal axis (12) of a foot passing between the second and the third toes through the most remote from them point (A) of a heel. Such shape of the foot bearing surface of the suggested shoe improves wearing comfort of the high/superhigh-heel shoes.

A high heel shoe has an insole, an outsole, and a shank embedded between the insole and outsole, the shank comprising a heel portion with a depression to accommodate a user's heel, and a lateral ridge element in front of the heel portion that exerts pressure against the forward movement of a user's heel when worn. The shank further comprises a front portion sloping downward from the lateral ridge along the arch of the insole, which optionally is padded.

Variable-density soles for articles of footwear and methods for constructing said soles are provided herein. In one embodiment, a variable-density sole for a footwear article comprises a first layer comprising a first density coupled to a bottom surface of an upper of the article of footwear; and a second layer comprising a second density greater than the density of the first layer, wherein the first layer is physically coupled to the second layer forming an interface between the layers. In this way, comfort of the article of footwear may be increased while decreasing the weight of the article of footwear. Further, forming the variable-density sole includes directly molding the first layer to a strobel board, stitching the strobel board to an upper, and injecting the second layer to the upper with the strobel board and the first layer. In this way, the production of a footwear article is simplified.

An apparatus includes a heel section, a mid-foot section, and a toe section. The heel section, the mid-foot section, and the toe section collectively have a geometric shape having a first slope of a polarity along an inner edge of the apparatus from the toe section to the heel section and a second slope of the polarity along the inner edge of the apparatus to an outer edge of the apparatus at the toe section.

An insole configured to be disposed in a shoe worn by a person, in particular during a walking period of the person. The insole includes a force and/or pressure measurement unit configured to acquire at least one representative measurement of the force and/or pressure exerted on the insole by the person, a motion measurement acquisition unit configured to acquire at least one measure representative of a motion of the person’s foot, and a processing unit configured to receive the force and/or pressure measurement and the motion measurement, to compute at least one walking parameter and to control the emission of stimulation at a walking moment according to the value of the walking parameter.

An insole device with the balancing, correcting, cushioning and supporting functions includes an insole body, reinforced hard strips are disposed on a bottom surface of the insole body, the reinforced hard strips crisscross around the bottom surface of the insole body, first through holes are evenly formed in the bottom surface of the insole body, the first through holes are located in gaps between the criss-crossed reinforced hard strips, and a second through hole is formed in a heel position of the insole body. The insole body is of a 3D stereoscopic arch structure, with an arch arc height of 15+/−10 mm. The insole body is formed by integrated injection of special nylon material, with a thickness of 2.5-10 mm, and a hardness of 30 D-100 D.

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.

Sandals with biomechanical foot support, robust usability and cost-effectiveness are disclosed. The footwear may comprise a biomechanical sole and a Y-shaped rubber strap anchored to the sole. The sole has a top surface including a raised contour on the medial side of the sandal, and a low profile heel cup. The raised contour on the medial side and the heel cup match the natural anatomic shape of the foot, and thus provides a biomechanical foot support. The bottom surface of the sole may be a roughed surface to provide necessary traction and friction when a wearer/user walks. The bottom surface further comprises a plurality of grooves to allow water to be expelled and increase traction.

An article of footwear has an upper, an outsole attached to the upper, and a midsole. The outsole includes a ground-engaging surface and an inner surface disposed on opposite sides. The midsole has a footbed and a bottom surface disposed on opposite sides. The bottom surface opposes the inner surface to define a cavity therebetween. The article of footwear also includes a first series of projections extending into the cavity from one of the inner surface and the bottom surface in a first direction toward the other of the inner surface and the bottom surface. The article of footwear also includes a second series of projection extending into the cavity from one of the inner surface and the bottom surface in the first direction toward the other of the inner surface and the bottom surface. The article of footwear also includes a quantity of particulate matter disposed within the cavity.
