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 sole structure for an article of footwear having an upper includes a heel region, a forefoot region, and a mid-foot region disposed between the heel region and the forefoot region. The sole structure also includes a fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a first segment extending between a medial side of the sole structure and a lateral side of the sole structure within the forefoot region, a second segment extending between the medial side of the sole structure and the lateral side of the sole structure within the forefoot region, and a web area disposed between and connecting the first segment and the second segment, the first barrier layer being attached to the second barrier layer within the web area.

A shoe device having bimodal structures, configured to selectively snap the device to at least one of a second position and a first position, which selectively snaps the shoe into a first position upon being subjected to a first bending force, apt for placement or removal of a foot, and selectively snaps the shoe into a second position upon being subjected to a second bending force, apt for securement of a foot or having no foot. A forward leaning, flexible stadium arch structure, assembled to form a heel notch mechanism, connects to a sole. A morphing shoe collar portion connects to a heel. These are combined via vector changing devices for greater functionality.

A sole arrangement for an article of footwear with a gradient depth value is provided. In one aspect of the disclosure, the sole arrangement extending from an end of a posterior area of the sole arrangement to an end of an anterior area of the sole arrangement, wherein the posterior area of the sole arrangement being formed under a heel area and the anterior area of the sole arrangement being formed under a forefoot area of a foot. The sole arrangement having an upper facing surface and a ground engaging surface, wherein the upper facing surface being on an opposite side of the sole arrangement than the ground engaging surface. The sole arrangement having a maximum posterior depth value. The sole arrangement having a maximum anterior depth value. The maximum posterior depth value may be smaller than the maximum anterior depth value by a first margin.
