A sports shoe includes a bottom sole and an upper vamp attached to the bottom sole. The bottom sole is provided with a compressible and stretchable air cushion. The upper vamp is provided with at least one airbag configured for covering and abutting against the foot. An air-charging valve is provided between the air cushion and the airbag. An air-intaking valve is provided between the air cushion and the external environment. An air-discharging duct is provided between the airbag and the external environment. The air-discharging duct is provided with an air-discharging valve. When the sports shoe is taken on the foot, the air cushion is used to inflate the airbag of the upper vamp automatically. After being inflated, the airbag surrounds the foot to cause the upper vamp of the shoe to fit well with the foot, to improve wearing comfort of the shoe.

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.

An assembly for a shoe or other footwear comprising computer controlled individually configurable inflatable air bladder orthotic structures that are monitored by a flexible pressure sensor pad. Comprising of a plurality of regions, each region including a respective plurality of air bladders; each respective air bladder being individually feed by a separate tube; each tube having a self-sealing valve disposed thereon and configured to allow air to enter the bladder through the valve while maintaining air pressure within the air bladder; and each self-sealing tube valve configured to allow air to escape through the valve via a computer controlled mini compressor integrated pump and release valve device. Where the air bladders are feed air through a mini smart compressor, which additionally can be controlled by a smart phone or computer. Said smart compressor connects with the shoe assembly at the heel pad plug in. The heel pad plug in comprising individual hoses and valves to fill and empty bladders and a power cord for recharging the shoe battery.

In example implementations, a self-adjustable sole is provided. The self-adjustable sole includes a soft sole, a flexible sole and a hard sole. The soft sole includes a first sensor. The flexible sole includes a bag containing an amount of fluid. The hard sole includes a controller that is in communication with the first sensor and the bag. The controller controls the amount of the fluid in the bag based on data collected by the sensor.

A process of making a family cell of homogenous inner bladders with varying elasticity includes a forming a plurality of inner bladders from a first material with a first elasticity. The inner bladders have interior surfaces during inner chambers and exterior surfaces exposed to an outside environment. The inner chambers are configured to store a fluid. A family cell is formed by fluidly connecting the inner bladders. One or more hybrid bladders are selected from the inner bladders and a second material having a second elasticity is applied to the hybrid bladders. The second elasticity is less than the first elasticity, such that the second material reduces the elastic qualities of the hybrid bladder.

A sports shoe includes a bottom sole and an upper vamp attached to the bottom sole. The bottom sole is provided with a compressible and stretchable air cushion. The upper vamp is provided with at least one airbag configured for covering and abutting against the foot. An air-charging valve is provided between the air cushion and the airbag. An air-intaking valve is provided between the air cushion and the external environment. An air-discharging duct is provided between the airbag and the external environment. The air-discharging duct is provided with an air-discharging valve. When the sports shoe is taken on the foot, the air cushion is used to inflate the airbag of the upper vamp automatically. After being inflated, the airbag surrounds the foot to cause the upper vamp of the shoe to fit well with the foot, to improve wearing comfort of the shoe.

An orthotic device for haptic terrain feedback and control includes a plate having a mechatronic unit, a bladder structure secured to the plate, the bladder structure having one or more bladder cells, and a passageway extending between the bladder cell and an environment outside the orthotic device. The orthotic device is configured to provide haptic feedback to a user by way of selective inflation and deflation of the one or more bladder cells.

A wearable weight scale, including an extensible fluid-filled insole for measuring and producing data relating to pressure changes within the extensible fluid-filled insole; a transceiver disposed about the extensible fluid-filled insole for transmitting the data; and one or more electronic devices for wirelessly receiving the transmitted data for displaying the data to a user.

Devices, systems, and, methods for measuring deformation variation in an insole to determine characteristics of a user, including weight and gait, are described herein. In some embodiments, a device includes an insole having a fluid reservoir configured to be disposed in a shoe, a deformation sensor, and a communications module. The fluid reservoir includes a first portion and a second portion. The deformation sensor is coupled to the fluid reservoir and is configured to measure a deformation in at least one of the first portion and the second portion. The communications module is configured to receive the measured deformation from the deformation sensor and transmit the measured deformation to a remote device.
