A sole for an article of footwear includes: an upper sole portion; and a pod assembly having a plurality of pods fluidly connected in series disposed below the upper sole portion, wherein the pod assembly extends from a lateral heel portion of the sole to a medial forefoot portion of the sole such that the plurality of pods compress substantially in sequence through a gait cycle of a wearer.

An adjustable bladder system for an article of footwear is disclosed. The bladder system includes an outer bladder that may be inflated using an external pump. A valve member may be disposed externally to the outer bladder. In addition, one or more tensile members may be disposed within the outer bladder to control deformation of the outer bladder during compression.

Disclosed herein are insoles useful for treating skin injuries on a foot, for instance ulcers. The insoles are customizable for each patient's foot and can include various portions of differing softness, depending on the needs of the patient. For instance, it can be beneficial for certain sections of the foot to contact a firmer material, whereas other sections contact a softer material. Some, or all, of the materials can include one or more biofidelic skin simulant materials. Thus, various implementations include one or more regions that can include the same or different materials. For example, a custom insole can include a heel support region, a midfoot support region, and a forefoot support region, and the support regions can be subdivided into medial and lateral support regions or toe regions. One or more regions may have a custom isolation segment to prevent the progression of ulcers and/or expedite wound healing.

An article of footwear may have an upper and a sole structure secured to the upper. The sole structure has a plurality of support elements, and each of the support elements include a shell and a core. The shell defines an interior void and is formed from a polymer material that extends around substantially all of the void. The core has a shape of the void and is located within the void, with at least a portion of the core being a polymer foam material. The polymer foam material of at least two of the support elements may have different densities.

Custom shoes for preventing diabetes, preventing diabetic foot caused by diabetic complications and easing ulcer pain of diabetic necrosis which disperse plantar pressure and prevent impact are proposed. The shoes may prevent shoes from creasing and deforming by attaching a deformation prevention frame to an external side of a sole; and increase weights of shoes by manufacturing shoes, wherein columns with which springs are embedded are formed on the bottom, an insole with massaging protrusions formed on the top of columns is attached to the top of the sole, an inner sole made of shock absorption material is attached to the top of the insole, and an upper combined to a sock lining is installed to the top of the insole.

An insole board for a high-heel shoe, said insole board includes a heel supporting area having a concave heel cup adapted to underlie a heel of the wearer, a medial arch support area adapted to underlie the arch of the wearer's foot and extending toeward of but short of the ball of the wearer's foot, and a forefoot area adapted to underlie the ball of the foot and forefoot of the wearer. The medial arch support area has a raised contour for supporting a portion of a sole of the wearer's foot underlying the wearer's arch, and the forefoot support area includes a hollow having a resiliently deformable material therein.

An article of footwear includes a sole structure with an auxetic structure and a filler. The auxetic structure includes an aperture. The filler is received in the aperture. The auxetic structure is configured to deform auxetically. The sole structure is configured to deform between a neutral position and a deformed position. The aperture is configured to deform as the sole structure deforms between the neutral and deformed positions. The auxetic structure includes a first material and the filler includes a second material. The second material is softer than the first material.

An article of footwear includes a sole structure with an auxetic structure. The auxetic structure includes an aperture. The sole structure also includes an aggregate that is received in the aperture. The auxetic structure is resiliently deformable between a neutral position and a deformed position. The auxetic structure can move auxetically between the neutral position and the deformed position. The aperture deforms as the auxetic structure moves between the neutral position and the deformed position. The aggregate includes a plurality of particles that support the foot as the auxetic structure deforms between the neutral position and the deformed position.

A contoured insole especially advantageous for users with medium to high arches is disclosed. It comprises a generally foot-shaped base extending from a heel end to a toe end, which comprises a top surface and a bottom surface. The bottom surface of the base preferably further comprises two indentations formed integrally therein in a forefoot area and a heel area. A forefoot pad and a heel pad are secured to each of said indentations. Preferably, the base is made from a polyurethane foam. The pads are made from rubber or synthetic rubber. A top sheet is coextensive with and secured to the top surface of the base. The top sheet is generally a fabric which preferably has antimicrobial characteristics. In use, the foot of the wearer, with or without a sock or stocking thereon, rests upon the top sheet in the foot-receiving compartment of a user's shoe.
