A sole structure for an article of footwear comprises a midsole including a first cushioning layer, a second cushioning layer, and a third cushioning layer. The first cushioning layer has a central portion, and a peripheral portion surrounding the central portion. The first cushioning layer, the second cushioning layer, and the third cushioning layer are stacked with the second cushioning layer directly overlying the peripheral portion of the first cushioning layer, and the third cushioning layer overlying the second cushioning layer and directly overlying the central portion of the first cushioning layer. The first cushioning layer has a domed lower surface extending away from the second cushioning layer and the third cushioning layer and substantially centered under the central portion.

A footwear device comprising: a sole assembly comprising at least one connective element; at least one protuberance assembly comprising a base and a cap, said base and cap configured to rotatively align; a locking fixture configured to lock and unlock said alignment of said base and cap; and a fastening fixture configured to fasten said base to said track in a selected position in said track.

An article of footwear includes an upper and a sole coupled to the upper. The sole includes an upper sole, a fluid filled bladder coupled to the upper sole, and a plurality of recesses disposed between the upper sole and the bladder. The bladder includes a plurality of chambers extending below the upper sole. The plurality of chambers hold a fluid. Ambient air is disposed within the plurality of recesses between the upper sole and the bladder.

A ground-engaging device that is capable of sustained rolling, stable braking, secure standing, and walking. In one preferred embodiment, the invention relates to a wheeled footwear device. In another preferred embodiment, the invention relates to a wheeled footwear platform. In yet another preferred embodiment, the invention relates to a wheeled artificial foot.

The Overshoe Walking Correctors (OWCs) are a medical walking device to go over a user's feet and shoes and changes the shape in the base of their current walking shoes for correcting gait. They need only be used by the obese and overweight population, who suffer limited mobility in their skeletal joints, due to the burden of weight they are carry on their bodies. The device was designed by Gail McGonigal an Occupational Therapist, who discovered the concept after falling on concrete severely bruising but not breaking her hip, due to a daily intake of oral calcium. She was only able to walk in rocker shoes containing no weightbearing capacity. Gail immediately understood how this concept will help the obese population improve their mobility in gait. She has designed the Overshoe Walking Correctors for all overweight people to wear, so they will feel no more pain in gait. The device is designed to have immediate and positive affects on their health, so the overweight population are encouraged to increase their physical mobility, while reducing the amount of sedentary sitting they perform on a daily basis. The intention is to relieve the pressure on acute medical services in all western populations, where obesity is a leading cause of chronic health issues needing constant attention by the medical practitioners in acute care hospitals.

An article of footwear includes an upper and a sole coupled to the upper.

Ambient air is disposed within the plurality of recesses between the upper sole and the bladder.

Biomechanically, a human foot operates as a lever of the second class during the motions involved with walking, running or jumping. Extending the toes during such motion increases the distance between the fulcrum and effort of the foot-lever and results in increased foot propulsion. Disclosed are apparatus and related methods of accomplishing extended toes during the motions involved with walking, running or jumping

A shoe may comprise an upper and a comfort sole attached to an outsole, the comfort sole having a radius of curvature at any point of a line from a heel to a toe and interfacing with outsole, wherein the lowest point of comfort sole and outsole, called the center of mass or balance point of the sole or natural balance point of the shoe, when placed on a substantially horizontal reference plane defines a transition zone of the roll of the foot having the highest radius of the comfort sole and the outsole, and in that the center of mass is behind point (B) of the metatarsals; and a rigid shell interposed between the upper and the comfort sole.

A sole structure includes: an anti-skid layer, a rigid layer, an elastic piece and a soft layer which are superimposed upon one another. With the characteristic of the elastic piece being elastically deformable, a rebounding force can be produced to act on the foot to stimulate the ligaments and muscles of the foot, which consequently corrects flatfootedness.

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.
