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.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

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 includes a first midsole body and a second midsole body. The first midsole body defines a ground-facing surface and a foot-facing surface opposite the ground-facing surface and includes a first midsole material, which has a first hardness. The second midsole body extends through the first midsole body. As such, the second midsole body extends beyond the ground-facing surface of the first midsole body. The second midsole body includes a second midsole material, which has a second hardness, and the first hardness is greater than the second hardness.

The invention provides a shoe (1) with a sole providing a dynamic foot arch support, the shoe comprising a rubber outsole (9) and an upper (10), the shoe further comprises a midsole (2), the midsole comprising a harder elastic material (4), a softer elastic material (5), wherein the harder elastic material has elastic hardness in a range 1.3 to 3 times higher than the softer elastic material. The shoe is distinguished in that the harder elastic material is arranged in a band (3) inside the periphery of the midsole, wherein the softer elastic material (5) is arranged in the midsole inside the band of the harder elastic material, and the shoe further comprises: a support structure (8) arranged below the softer elastic material in direction medial to lateral and positioned from vertically below to 4 cm in front of the naviculare bone center of a typical user with feet fitting the shoe size, wherein the support structure has higher elastic hardness than the harder elastic material, with a larger vertical dimension medial compared to lateral as seen with the shoe standing on a horizontal surface, providing increased support under the medial side of the foot arch compared to the lateral side of the foot arch.

Footwear used for high performance activities such as running can be adhesively attached to the plantar surface of feet rather than uppers or straps. The upper surface of the protective layer of the footwear can have adhesive regions that secure the foot to the footwear and other regions that are not adhesively coupled to the foot. The adhesive regions can be under the heel, along the lateral side of the foot, under the first through fifth metatarsophalangeal (MTP) joints and around the perimeter of the foot above the plantar surface.
