An insole with heat generating system is disclosed, which comprises an insole, a piezoelectric module disposed inside the insole and electrically connected with each other to form an electrical circuit, two flexible conductive strips having a first conductive copper piece and a second conductive copper piece disposed thereon, and at least one resistive heating chip. Wherein the piezoelectric module generates the electrical energy through stepping on the insole, and then turns into the heat energy through the resistive heating chip, thereby generating a temperature for the insole, so the insole with heat generating system can adjust the temperature appropriately, its safety is high, most importantly, the invention does not need to add the battery to generate heat.

An article of footwear includes an outsole that has a bottom portion and a medial arch portion extending upward from the bottom portion. The medial arch portion of the outsole has a base and a plurality of protrusions extending outward from the base. The plurality of protrusions are arranged in vertical alignments. In each one of the vertical alignments, at least one protrusion of the plurality of protrusions is closer to the bottom portion and has a larger effective diameter than at least one other protrusion of the plurality of protrusions that is further from the bottom portion.

Disclosed herein are improved cross-linked resilin compositions and methods of making these improved compositions. These include new methods of cross-linking resilin compositions, use of polar nonaqueous solvents for adjusting material properties of cross-linked resilin solid compositions, and resilin foam compositions and methods of making the same.

An integrated memory foam high heel shoe for comfort and security includes a base having a top side, a bottom side, a flat forefoot portion, an arch portion, a heel portion, and a perimeter. A shoe body is coupled to the perimeter of the base. A memory foam insole is continuously coupled to the top side of the base. A platform is coupled to the bottom side of the base under the forefoot portion and a high heel is coupled to the bottom side of the base under the heel portion.

An electrically conductive shoe includes a shoe body having an upper, a midsole, and an outsole, and the outsole has a receiving chamber. The receiving chamber is communicated with a bore of the midsole. A conductive device is mounted on a bottom of the outsole. A flexible conductive member has an end electrically connected to the conductive device and an opposite end extending to an inner space of the upper through the receiving chamber of the outsole and the bore of the midsole and attached to an inner side of the upper.

A reusable, customizable shoe-insole having malleable support material configured to assume a first arch-support structure and a first metatarsal-support structure responsively to application of foot pressure of a first user and maintain the first arch-support structure and the first metatarsal-support structure during the absence of foot pressure and assume a new arch-support structure and a new metatarsal-support structure responsively to each new application of foot pressure of additional users.

An abrasive insole and method of manufacture. The insole is integrated into the shoe at the time of manufacture. The insole provides a roughly textured surface to abrade the skin on the soles of the feet for purposes of cosmetic appeal and skin health. The abrasive insole works similarly to the textured, sandpaper-like tools that are used in pedicure to soften the skin of the foot by exfoliation. The method of manufacture involves a mold of a sand-and-polymer mixture to produce a flexible insole; one iteration is of 3/32 to 0.25-inch thickness.

A holistically improved shoe that incorporates beneficial aspects relating to a variety of interconnected elements, including comfort, sustainability, washability, ease of manufacturing, style, freedom and natural movement of the foot, as well as the sensory experience of a user. The shoe contains a removable insert that is configured to be removed and washed in between uses or as needed, such that a sock or other liner is unnecessary. The shoe further includes a footbed and an outsole that contain matching tread patterns. The matching tread patterns of the present technology allow the footbed and the outsole to move in concert by splaying during a stride in order to better absorb shock by mimicking the natural movements of the foot.

Disclosed is a platform for generating and delivering 3-D printed wearables. The platform includes scanning, image processing, machine learning, computer vision, and user input to generate a printed wearable. Scanning occurs in a number of ways across a number of devices. The variability of scanning generates a number of scanning output types. Outputs from the scanning process are normalized into a single type during image processing. The computer vision and machine learning portions of the platform use the normalized body scan to develop models that may be used by a 3D printer to generate a wearable customized to the user. The platform further provides opportunities for the user to check the work of the scanning, image processing, computer vision, and machine learning. The user input enables the platform to improve and inform the machine learning aspects.

An insole for insertion into footwear, including a base layer extending through a forefoot portion, a midfoot portion, and a heel portion of the insole, and an arch shell in the midfoot portion of the insole beneath the base layer, wherein the arch shell has a thickness of no more than 2 mm.
