A walking-assisted air-jet insole includes an insole base. A plurality of pressed-air outlet units that can generate airflow based on stepping pressure are provided on the insole base; the pressed-air outlet unit includes a cavity for retaining air. An upper part of the insole base is provided with an upper air hole that communicates with the cavity, and a lower part of the insole base is provided with an air sac part that is elastically deformed and restored based on the stepping pressure. A volume of the cavity can be changed based on the elastic deformation and restoration of the air sac part. A lower end of the air sac part is provided with a convex column that moves up and down based on the stepping pressure. The cavity includes an upper cavity portion and a lower cavity portion from top to bottom.

An article of footwear includes a motorized tensioning system, sensors, and a gesture control system. Based on information received from one or more sensors the gesture control system may detect a prompting gesture and enters an armed mode for receiving further instructions. In the armed mode the system may detect a variety of different control gestures that correspond to different tensioning commands.

Foot support systems include a fluid flow regulator and/or valve that: (a) can operate as a stop valve to stop transfer of fluid between a first fluid container and a second fluid container, (b) can open in a controlled manner to allow transfer of fluid from the second fluid container to the first fluid container, (c) can open to equalize pressure in the first and second fluid containers, and (d) can act as a check valve to enable flow of fluid from the first fluid container to the second fluid container when/if gas pressure in the first container exceeds that in the second container by a predetermined amount. Additional features relate to fluid flow control systems and methods, systems and methods for changing and controlling the crack pressure of a valve (e.g., a check valve), and/or systems and methods for matching foot support pressure features in two different sole structures.

A shock absorption shoe, having a sole and at least one shock absorption module each having an outer shell, an inner core, an air cushion cylinder and a bottom cover, and each being connected to an air tube. The inner core is sleeved into a cavity of the outer shell from the top. A position limiting structure is provided between the inner core and the cavity. The air cushion cylinder is sleeved within the cavity. The bottom cover covers the bottom of the cavity. The shoe has a bottom layer, a middle layer and a top layer; the middle layer contains at least one mounting hole for mounting the at least one shock absorption module. The air tube is in an air tube groove on the middle layer, and one end of which is connected to the air cushion cylinder while another end is connected with a nozzle.

Dual-layer insole apparatuses for diabetic foot lesion prevention and related methods are provided. Some insole apparatuses have a body defining a plurality of cavities configured to be coupled to a fluid source. The fluid source can deliver fluid to vary internal pressures of the cavities. The body further defines an insole-shaped structure.

Foot support systems for articles of footwear or other foot-receiving devices include a compressor or other gas source used to control gas pressure provided in one or more pressure adjustable fluid-filled bladders used to support a wearer's foot. Additional features relate to fluid flow control systems and methods that include a plurality of valves to control an inflation configuration for supplying gas to the one or more adjustable fluid filled bladders or a deflation configuration for releasing gas from the one or more adjustable fluid filled bladders.

An electronically controlled bladder assembly includes an adjustable pressure bladder and a constant pressure reservoir connected by an electronically controlled valve. The electronically controlled valve is operated in a manner that inflates the adjustable bladder when the current pressure is below a target pressure and in a manner that deflates the adjustable bladder when the current pressure is above the target pressure. The inflation and deflation of the adjustable bladder are achieved in an iterative manner by controlling the flow of fluid between the constant pressure reservoir and the adjustable bladder over several cycles of heel strikes.

A big data artificial intelligence computer system is used for medical care connecting to sensor-equipped smartphones of users of footwear. The footwear has smartphone-connected soles with sensors and configurable structures. The smartphone is also connected to sensors located on the users' body, including proximate to its center of gravity and/or on the head. The web and/or cloud-based computer system is configured to use the big data techniques of machine learning in a database compiled from millions of smartphones to perform operations on billions of data sets from the smartphones of the footwear users. The correlations found from the big data operations provide solutions to medical problems of the footwear users involving their body structure and/or function. The solutions are implemented by configuring the users' footwear soles, including active configuration, including during running and/or walking to optimize corrections to the structure and/or function of their bodies.

A sole or insole for an orthopedic shoe for persons with hallux valgus. The sole or insole includes a main part located at least under and supporting the Digitis Pedis II to V and the ball of the foot, and an element movably connected to the main part that is located under and supports the Digitis Pedis I. The main part of the sole or insole includes a cavity under the Digitis Pedis II to V and/or the transverse arch of the foot that contains a hydraulic, mechanical, pneumatic, electric or other device that causes rotary movement of the moveable element in the horizontal plane laterally away from the main part during a walking movement, in particular caused by the compressive force caused by the wearer’s own weight on the sole or insole.

An article of footwear includes an upper and a sole coupled to the upper. The article of footwear includes an inflation system. The inflation system includes an inflatable bladder, a pump in fluid communication with the bladder, and a control circuitry operatively linked to the pump. The pump adjusts the air pressure of the inflatable bladder. The control circuitry receives a command signal from a remote device, and upon receipt of the command signal, the control circuitry transmits an actuation signal to the pump to adjust the air pressure of the inflatable bladder.
