An article of footwear includes an upper and a sole structure secured to an underside of the upper. The sole structure includes a midsole; a ground contacting outsole surface; and a cushioning system disposed between the midsole and the ground contacting outsole surface. The cushioning system includes a plate comprising an upper plate and a lower plate provided in a spaced relationship. The upper plate and lower plate are integrally connected at a posterior portion of the sole structure. A midfoot fluid-filled chamber is provided between the upper plate and the lower plate within the midfoot region, and a forefoot fluid-filled chamber is provided between the upper plate and the lower plate within the forefoot region.

A footwear component that includes a sole including a recessed area and a support member positioned in the recessed area, where the support member includes a main support, a front support that extends at least partially over a front end of the main support, and a rear support that extends at least partially below a rear end of the main support. A cushion member is positioned between the front support and the main support or the rear support and the main support, where the cushion member is configured to control movement of the front support or the rear support.

A balanced insole structure with a massage function includes an insole main body and a connecting portion; the arch portion of the insole main body is provided with a convex portion matched with the curvature of the sole of the foot; the connecting portion is connected to two ends on the lower side of the convex portion, thus forming a stabilization cavity through their connection; and the insole main body is also provided with a massage protrusion on its upper surface. In the invention, the provision of the insole main body with the massage protrusion on its upper surface can realize the massage function of the insole.

An article of footwear comprising a sole including a midsole and an outsole attached to the midsole, and a support member positioned on a bottom surface of the midsole, where the support member has a curved surface that extends from a rear end to a front end of the support member.

An article of footwear includes an upper and a sole structure secured to an underside of the upper. The sole structure includes a midsole; a ground contacting outsole surface; and a cushioning system disposed between the midsole and the ground contacting outsole surface. The cushioning system includes a plate comprising an upper plate and a lower plate provided in a spaced relationship. The upper plate and lower plate are integrally connected at a posterior portion of the sole structure. The sole structure further including at least one of a midfoot fluid-filled chamber provided between the upper plate and the lower plate within the midfoot region, or a forefoot fluid-filled chamber is provided between the upper plate and the lower plate within the forefoot region.

A sole structure for an article of footwear has a sole plate that may include a midfoot region, and also may include a forefoot region or a heel region. The sole plate may have a foot-facing surface with ridges extending longitudinally in the midfoot region and in the forefoot region or heel region. The sole plate may have a ground-facing surface with grooves extending longitudinally in correspondence with the ridges. A thickness of the sole plate from the foot-facing surface to the ground-facing surface may vary at a transverse cross-section of the sole plate through the ridges, or along a length of at least one of the ridges, or at both the transverse cross-section and along the length of the at least one of the ridges. 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.

A shock-absorbing shoe using a spring, comprising: a spring for absorbing shock by providing an elastic force; an outsole which constitutes the bottommost sole of a shoe; an upper sole which is fixed to the top of the outsole, has a gap between the heel part thereof and the heel part of the outsole so as to provide a space in which the spring is provided, and is lowed by the weight of a user or raised by the elastic force of the spring; a lower spring seat which is formed on the upper surface of the outsole and supports the lower end part of the spring; an upper spring seat which is formed below the bottom of the upper sole and supports the upper end part of the spring; and a raising and lowering guide for guiding the lowering and raising of the upper sole straightly.

A shoe has a shoe upper configured to receive a foot of a user, a sole coupled the shoe upper and having a cavity, and a sole spring in the cavity. The sole spring has a first leg and an opposite second leg, and the sole spring is removably positioned in the cavity. Accordingly, when the user presses the shoe into contact with a support surface, the first leg and the second leg flex toward each other thereby cushioning the foot of the user, and when the user moves the shoe away from the support surface the first leg and the second flex away from each other thereby propelling the user away from the support surface.

An article of footwear including a sole and a first support member and a second support member positioned on the sole, where the first support member and the second support member are separated from each other, and where the first support member has a main body and a terminal end that extends at least partially below the main body of the first support member, and the second support member has a main body and a terminal end that extends at least partially below the main body of the second support member.

An article of footwear is provided and includes an upper, a sole secured to the upper and including a stabilizing member extending outwardly from the upper, where the stabilizing member includes a groove that separates the stabilizing member into a medial balancing member and a lateral balancing member, and the medial balancing member and the lateral balancing member move independently of each other to provide balance and stability on different terrains, and a support plate is positioned between the upper and the sole.
