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.

A sports shoe for flat foot prevention and correction, including a sole, an upper and an insole, an area of the insole corresponding to the arch of human foot is D-shaped area for auxiliary correction training, the arc part of the D-shaped area are divided into three sections, namely a middle section connected to other parts of the insole as a whole and two opening sections which are between two ends of the middle section and two ends of the vertical line part of D shape, and the opening sections are separated from the other parts of the insole to form openings, the bottom surface of said D-shaped area is fixedly bonded with an airbag, the upper is fixedly equipped with a press type inflation and deflation valve, the air outlet of the inflation and deflation valve connects to the air inlet/outlet of the airbag through an inflation tube.

A shoe includes a shoe sole and a shoe main body. The shoe sole is configured to be connected to the shoe main body and forms an accommodating space with the shoe main body. The shoe sole includes a supporting member and a supporting insole. The supporting member is provided with a blowing device and a blowing channel. One end of the blowing channel is connected to the blowing device, and the other end is connected to the upper surface of the supporting member. The supporting insole includes an insole surface; an air hole is provided in the insole surface; one end of the air hole is configured to be communicated to the accommodating space; the supporting insole is arranged on the supporting member.

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.

Foot support systems, e.g., for articles of footwear, include systems for changing the hardness or firmness of the foot support portion (e.g., of a sole structure) and/or systems for moving (e.g., selectively moving) fluid between various portions of the foot support system. Such systems may include: a foot support bladder, a pump, and a fluid reservoir. Two or more fluid transfer lines may be provided to connect these components, and these fluid lines are equipped with fluid flow control device(s) and/or check valves to enable selective movement of fluid between the fluid reservoir and the foot support bladder. Such systems enable one to set and maintain two or more foot support pressures in the foot support bladder.

A one-way air inlet member, cushion airbag pad and manufacture method thereof. The one-way air inlet member configured for mounting on a cushion airbag pad, wherein external gas enters the cushion airbag pad through the one-way air inlet member, but the one-way air inlet member prevents the gas in the cushion airbag pad from flowing out to outside. By means of a simple one-way air inlet member, the slow gas leakage can be prevented, thereby effectively preventing the air leakage of the cushion airbag pad, the slow gas leakage can be prevented, thereby effectively preventing the air leakage of the cushion airbag pad, and thus no need to be frequently inflated, convenient to use.

A footwear device is provided, the footwear device defining a plurality of chambers and including a resilient base on which the plurality of chambers are disposed. In the absence of any forces applied to the resilient base, a height of an upper surface of the resilient base under a first one of the chambers is higher than a height of the upper surface of the resilient base under a second one of the chambers. Other applications are also described.
