A pressure-relieving footwear is an apparatus that supports and comforts a user's foot. The apparatus absorbs shock that traverses through the footwear, limiting the impact against the foot of the user. The apparatus includes a footwear, a cushioning layer, a support layer, and a first shock absorbing pad. The footwear protects user's foot and enhances the outfit of the user. The footwear includes an insole, an outsole, and an elongated heel. The outsole includes a forefoot portion and an aft portion. The cushioning layer absorbs the shock and the support layer cradles the foot. The insole is connected across the outsole. The cushioning layer is connected across the insole, opposite to the outsole. The support layer is connected across the cushioning layer, opposite the insole. The elongated heel is connected adjacent to the outsole. The first shock absorbing pad is integrated into the footwear, adjacent to the forefoot portion.

An insole assembly is provided comprising an insole having an upper surface upon which an underside of a foot may contact and be supported. The insole assembly has at least one protrusion which projects away from the upper surface of the insole. At least one of the protrusions is detachably connected to the insole. The protrusions may be interchanged to customize an insole assembly to provide enhanced cutaneous stimulation of targeted regions of a foot.

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.

A sole structure for an article of footwear. The sole structure includes at least one support plate located on an underside of a midsole on a medial forefoot side of the midsole and extending from a medial edge of the midsole to at least a longitudinal center line of the midsole, wherein a lateral edge of the plate is located medially of the lateral edge of the midsole. The support plate may contain at least one sipe or groove extending laterally across the midsole to provide flexibility in a forefoot-to-heel direction of the midsole. The support plate may contain at least one rail.

The present invention is footwear having a convex shaped outsole with opposing wedge shaped configurations in the bottom of the front sole section and the back sole section which provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The present invention is also footwear convex shaped in the longitudinal direction with a split sole having opposing wedge shaped configurations in the bottom of the front sole section and the back sole section that provide rotation of the front sole section and the back sole section in opposite directions when weight is applied. The invention further includes footwear having at least one pair of wedges on the outsole which provide footwear having improved arch support. The invention is also footwear with a flexible, elastic, member between the front sole section and the back sole section of the sole.

A shoe sole includes an outsole and a sole body. The sole body includes a low hardness portion made of a foam material having relatively low hardness and a high hardness portion made of a foam material having relatively high hardness. The low hardness portion is provided to define an entire area of a lower surface of the sole body. The high hardness portion is disposed only in a specific region of a region located above the low hardness portion of the sole body.

A sole structure for an article of footwear may have a midsole system that includes a sole plate having a forefoot region and a midfoot region. The sole plate may have a foot-facing surface and a ground-facing surface opposite to the foot-facing surface. The sole plate may define a through hole extending from the foot-facing surface to the ground-facing surface in the forefoot region. The through hole may be closer to a medial edge of the sole plate than to a lateral edge of the sole plate. The sole plate may have ridges extending longitudinally in the midfoot region and in the forefoot region. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.
