A user device (100) is provided. The user device is a footwear device (100a), a medical device (100b), a mattress device (100c), or a seat cushion (100d), and is shaped to define a plurality of chambers (28). Apparatus for use with the user device includes circuitry (34, 152) and a pump (38, 130). The circuitry includes at least one device pressure sensor (36) that measures pressure in the chambers. The pump is couplable to the user device by a user 18, and the circuitry actuates the pump to selectively inflate or deflate the plurality of chambers to at least two different respective pressures. The pump is decouplable from the user device without the decoupling affecting the respective pressures in the chambers. Other applications are also described.

An article of footwear may include an upper forming a void within the footwear, a sole structure secured to the upper, and a chamber that encloses a pressurized fluid. The sole structure includes a depression. The chamber is located within the void of the upper and located on the depression of the sole structure. The chamber may include a plurality of fluid-filled subchambers, a manifold, and a connection fluidically-connected at least one of the subchambers to the manifold. The subchambers may enclose the pressurized fluid at different pressures. The subchambers may be separated from one another by a bonded area in the direction extending between the heel and toe of the chamber.

An article of footwear includes an upper for securing the article of footwear to a wearer. The footwear also includes a sole assembly operatively coupled to the upper. The sole assembly includes a bladder that contains a fluid. The bladder has a posterior portion, an anterior portion, and a middle portion disposed between the posterior and anterior portions. The posterior portion has a heel recess that is approximately coincidental with a center of a heel of the wearer. The middle portion includes a neck chamber that extends between the posterior and anterior portions. The neck chamber is elongate and has a width that is less than both the posterior and anterior portions, and the anterior portion has a plurality of toe recesses that extend generally away from the neck chamber.

An insole for offloading injuries on an area of a plantar surface of a patient's foot includes a body having a shape corresponding to the plantar surface of the patient's foot including a top surface and a bottom surface; and at least one supportive, deformable, deflatable bubble chamber. The at least one bubble chamber extends from the top surface of the body. The at least one bubble chamber is configured to be deflated to relieve pressure on the plantar surface of the patient's foot. A kit including the insole and an article of footwear including a sole, an upper connected about a periphery of the sole defining an interior of the article of footwear, and the insole positioned in the interior of the article, are also provided.

A cushioning element for an article of footwear includes a bladder having a first barrier layer and a second barrier layer joined together along a seam to define a chamber and a support element disposed within the chamber and having a support member and a plurality of flexible support legs each extending from a first end attached to the support member to a second end disposed between the first barrier layer and the second barrier layer within the seam.

The present invention relates to a shoe sole and manufacturing method thereof, wherein the shoe insole comprises: a body that is formed by a space support so as to be inserted into a shoe and support at least a portion of a sole; and a finishing band that is joined along an open edge of the body to the circumference of the body so as close the open edge and allows a filler to be injected into an inner space of the body. Since the finishing band is closely lap joined along the open edge of the body by fusing, a joint part between the finishing band and the body receives a shearing force even when the pressure inside the body is increased by injecting the filler into the body, and thus the compressive strength of the joint part can be significantly increased. Accordingly, the sealing performance of the joint part can be further improved, and thus the usable life or performance of the shoe insole can be significantly improved.
