In some examples, a sole layer for a footwear includes a housing structure, a cell in the housing structure, a solid support inside the cell to maintain a shape of the cell, and an inlet to the cell to receive an injected material to dissolve the solid support.

A boot includes a rigid outer shell including a base portion adjacent to a portion of a foot of a subject, a leg portion adjacent to a portion of a leg of the subject, and an ankle support portion integral with and coupling the base portion of the main body with the leg portion of the main body, the ankle portion of the main body being adjacent to two opposing sides of an ankle of the subject, the ankle support portion of the main body having one or more removable elements. A first one of the one or more removable elements, adjacent to a first one of the two opposing sides of the ankle, is configured to be removed from the rigid outer shell to aid in preventing contact between an incision area on the first side of the ankle of the subject and the rigid outer shell.

Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.

An orthotic footwear system including a removable outsole, a removable reinforced hollow midsole attached to the top of the outsole, and a removable insole attached to the top of the midsole. A removable metatarsal pad can be attached to the top of the insole, and removable support inserts can be attached around the insole for additional support of problematic areas. Support inserts can be used to support the arch area, the heel area, or both. Each of the removable parts can be interchanged with parts of the same type having different ergonomic characteristics. The user can change the parts of the orthotic to suit their needs. Further, the support inserts can be used apart from the rest of the system, with any insole configured to receive them.

An article of footwear includes an upper and a sole member connected to upper. The sole member includes a plurality of tubular structures. Each of the plurality of tubular structures is at least partially filled with a loose granular material.

The present application discloses footwear comprising a body structure in which at least upper is made of one continuous folded composite material comprised of layered sheets of material.

Provided is a shoe or device for inserting into a shoe, having a shallow channel on a top side of a contoured insole or shoe, specifically under the 1.sup.st metatarsal shaft of the wearer. The shoe also has a rear region or heel cup positioned to underlying a wearer's calcaneal tuberosity, the rear region being shaped to accommodate a planer surface of the wearer's calcaneal tuberosity, an upper surface of said rear region having a raised portion underlying an area of the wearer's calcaneus immediately forward of the wearer's calcaneus tuberosity.

An improved article of footwear is disclosed herein. The article of footwear includes an upper and a harness. The upper has a midfoot region, a forefoot region, a medial side, a lateral side, and an opening configured to receive a foot of a wearer. The harness extends between the midfoot region and the forefoot region, and includes a panel, a cable, and a tightening mechanism. The tightening mechanism tensions the cable against the panel to apply a compressive force to the foot of a wearer to secure the foot of the wearer in the upper. Consequently, the internal harness prevents the foot of a wearer from shifting or translating in the upper, such as during athletic activity like cutting.

A boot includes a rigid outer shell including a base portion adjacent to a portion of a foot of a subject, a leg portion adjacent to a portion of a leg of the subject, and an ankle support portion integral with and coupling the base portion of the main body with the leg portion of the main body, the ankle portion of the main body being adjacent to two opposing sides of an ankle of the subject, the ankle support portion of the main body having one or more removable elements. A first one of the one or more removable elements, adjacent to a first one of the two opposing sides of the ankle, is configured to be removed from the rigid outer shell to aid in preventing contact between an incision area on the first side of the ankle of the subject and the rigid outer shell.

Insole apparatus for use in footwear is provided, comprising a planar insole base positionable on top of a base interior surface of the footwear, and at least one attachment accessory removably attachable to the insole base by way of a plurality of attachment elements distributed on at least one of an upper surface of the insole base and a lower surface of the attachment accessory. The plurality of attachment elements define attachment points, which are arranged with a predefined consistent spacing to enable interchangeability of the attachment accessory with other attachment accessories having similarly arranged attachment points. The interchangeability and removability of attachment accessories allows for customization of the insole apparatus for a user's needs and size and shape of foot.
