A sole board for an article of footwear includes a plate that has a forefoot region, a midfoot region, and a heel region. The sole board includes a channel disposed in a top surface of the plate in the forefoot region. The channel extends from a lateral edge of the plate to a medial edge of the plate. A characteristic of the channel at the lateral and medial edges of the plate is different than the characteristic of the channel at a middle of the channel.

A fiber-composite insert for footwear comprises a plurality of ribs arranged in a lattice structure, the ribs comprising a plurality of fibers in a resin-matrix.

A material is disclosed herein that may include a plurality of chambers. A wall, a bottom surface, and a top surface may define a chamber. The wall may have a top portion and a bottom portion where the top portion may be adjacent to the top surface, and the bottom portion may be adjacent to the bottom surface. The wall may include an elastic material, and an aerogel powder or an aerogel foam may be disposed within the chamber. This material can be incorporated into clothing and shoes, for example.

The present invention relates to a shoe which comprises an insole having lapillus attached thereto and a foot correction outsole, wherein: the insole is positioned inside the shoe, has an upper shape protruding by a predetermined interval, and includes lapillus attached to the position of a first kidney meridian point (KI1) to perform acupressure on the foot of a shoe wearer and thus help blood circulation; and the outsole has elastic forces differently applied to positions on a plane, so that health-related harmful factors caused by a weight bias due to genu varum or genu valgum are prevented and legs are corrected. As described above, a shoe which comprises an insole having lapillus attached thereto and a foot correction outsole according to the present invention has lapillus emitting far-infrared rays, having a predetermined porosity, and exhibiting an aesthetic impression, wherein: the lapillus is attached to a shoe insert to enhance health and secure an aesthetic impression; and another shoe insert having a different protrusion surface may be used to adjust the degree of acupressure applied to the sole of a user's foot. The shoe also comprises a lower plate which is made of a lattice-shaped elastic substance and by which a user's body weight may be buffered. The insole has a foot corrector attached thereto and installed thereat, and the outsole has regions having different elastic forces. Accordingly, the shoe can prevent a shoe wearer from developing hallux valgus and correct genu varum or genu valgum.

The present invention relates to a high heeled shoe 1 having a forefoot section 5, an arch section 7 and a heel section 6, the high heeled shoe 1 comprising a constructive sole 2, a heel 8, directly or indirectly attached to a lower surface 3 of the heel section 6 of the constructive sole 2; an upper part 9, attached to the constructive sole 2 such that the upper part 9 and the constructive sole 2 together form an enclosure configured to receive and hold a foot in a specific configuration and an insole 10 comprising auxetic material.

Provided is an insole-type electronic device wherein the electronic module is not susceptible to impact and/or load due to walking or running. The insole-type electronic device is an electronic device wherein an electronic module has been incorporated in the insole that is laid on the midsole of a shoe and contacts the sole of the foot. The insole-type electronic device has an insole body with the shape of a normal insole. Said insole body has a heel-protecting part that extends upward from the back end of the heel section of the insole body along the perimeter of the back end of the heel section. Additionally, the insole-type electronic device has an electronic module that is housed in the heel-protecting part.

Systems and methods for supporting an object to be printed in an additive manufacturing process are disclosed. Support structures (202, 302, 402, 502, 602) are prefabricated and positioned in the build area of a 3D printing device prior to printing the 3D object. When the object has been printed, the support is removed and can be reused to print another object by repositioning the support structure in the building area of the additive manufacturing device.

A material that includes a polymer foam and at least one polar dopant molecule included in the polymer foam, wherein the material is a piezoelectric.

An article of footwear is configured to be worn so as to at least partially cover a wearer's foot. The footwear includes at least one optical fiber on an internal surface of the footwear. The at least one optical fiber is configured to project radiation having a therapeutic wavelength through the at least one optical fiber and toward at least one of the wearer's foot, ankle or leg when the footwear is being worn so as to at least partially cover the wearer's foot.

An arch-adaptive smart insole according to the present invention includes: an insole cushion foam (10) which has a shape corresponding to the shape of the foot and which is made of an elastic foam; and an arch spring module (20) which is loaded in a first loading well (11) of the insole cushion foam (10), and which supports the arch of the foot by means of the interposition of a closing part (18) of the insole cushion foam (10) for closing the upside of the first loading well (11), wherein the arch spring module (20) comprises at least a first coil spring (21) and a second coil spring (22), and the first coil spring (21) having a diameter smaller than that of the second coil spring (22) is positioned inside the second coil spring (22).
