The fluid stored in the lower inflatable cushion (4) can also be partially or totally evacuated (4) by means of the valve (5); an upper inflatable cushion (6), intended to be fixed in an area and on a surface of the (S) footwear where the laces are usually placed; a flexible hose (7) that is non-deformable in terms of volume that permanently ensures fluid communication between the lower inflatable cushion (4) and the upper inflatable cushion (6); where the movable inner sole (2) is capable of moving between a first extreme position, in which the movable inner sole (2) compresses to a minimum the lower inflatable cushion (4), the lower inflatable cushion (4) having maximum volume and the upper inflatable cushion (6) having minimum volume implicitly, and a second extreme position, in which the movable inner sole (2) compresses to the maximum the lower inflatable cushion (4), the lower inflatable cushion (4) having minimum volume and the upper inflatable cushion (6) having maximum volume; the system additionally comprises a locking/unlocking assembly of the movable inner sole (2) in/from the second extreme position.

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.

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 includes a first plate, a second plate, a third plate, filler material, springs, an insole, and a midsole. The first plate and the second plate are hingedly connected to each other. The filler material is located between the first plate and the second plate. The springs are located within openings in the filler material. The third plate is affixed to a top surface of the first plate. The insole is located above the third plate. The first plate is made of a thermoplastic elastomer, and the third plate is made of carbon fiber. Another shoe includes a midsole, a plate located above the midsole, springs located at least partially within openings in the midsole, and a spring holding unit located below the midsole for holding the springs. The spring holding unit includes spring holding members and branches connecting corresponding spring holding members.

A shoe includes a first plate and a second plate that are located in a portion of the shoe between an upper and an outsole of the shoe, and a nest formed as a bag filled with one or more gasses located between the first plate and the second plate. The shoe may further include one or more springs located in cavities in the gas filled nest for biasing the first plate and the second plate apart from each other. Pods may be located within the openings in the center of the springs, and the pods may be filled with one or more gasses. The pods may protrude from a bottom or a top surface of the nest. Spring sandwiches including one or more springs positioned between plates may be constructed and placed in various portions of a shoe. The shoe may also include piping with lights.

Foot support systems (and articles of footwear including them) include: (a) a medial side member having one or more medial side supports (e.g., ribs); (b) a lateral side member having one or more lateral side supports (e.g., ribs); and (c) structure (such as a hinge system) configured to move the foot support system (e.g., the medial side support(s) with respect to the lateral side support(s)) between: (a) a foot-insertion configuration and (b) a foot-containing configuration. In moving from the foot-insertion configuration to the foot-containing configuration, the foot support system can be changed between an open condition and a closed condition.

A shock absorbing device having at least one nautilus spring disposed between two members is described. When the members move toward each other, the one or more nautilus coil springs are canted and compressed. The shock absorbing device takes advantage of the unique force-displacement curve of canted springs and reduces bounce back.

A modular article of footwear has a shock absorbing insert placed between the insole and the outsole thereof, for example at the heel. The insert includes a spring carrier having upper and lower portions, each having a plurality seats for receiving a respective ends of respective coil springs. Each of the springs extends between said upper and lower portions and is captured therebetween. A pair of opposed permanent magnets generates a separating force which supplements the supporting force of the mechanical springs. The insert may also contain a device for converting mechanical energy to electrical energy.
