A shape shifting orthotic sole having a cushioning layer, shape changing layer, and a sensing layer in communication, the shape changing layer and sensing layer communicatively coupled with a power source and circuitry unit which provides for default and evolving settings, and automatic and manual support settings for the shape changing region as a result of input from the sensing layer. The shape shifting orthotic sole may communicate with a cellular device and other device able to maintain mobile applications, and an IOT Health Monitoring Device during the operation of the shape shifting orthotic sole.

A plantar surface pressure offloading system includes an insole capable of coupling with a shoe and interfacing with a foot. A number of compressible bladders and pressure sensors are coupled to the insole. Each bladder has an adjustable compressibility, and each pressure sensor is configured to measure a pressure exerted on a respective portion of the foot. A controller of the system can perform, for each compressible bladder, a compressibility adjustment process including (i) receiving, from a respective pressure sensor associated with a respective bladder, a signal indicative of a pressure exerted on a respective portion of the foot, (ii) determining, based on the signal, that the pressure exerted on the respective portion of the foot exceeds a threshold pressure, and (iii) responsive to the determination, adjusting the compressibility of the respective bladder, thereby offloading pressure from the respective portion of the foot to a different portion of the foot.

The present disclosure provides a one-way air inlet valve for a cushioning airbag device and the cushioning airbag device. The one-way air inlet valve includes an air outlet member being in air communication with the at least one airbag; an air inlet member clamped into the air outlet member and being in air communication with the air outlet member; and a block movably arranged between the air outlet member and the air inlet member, the block comprising an engagement surface. Wherein the one-way air inlet performs one-way intake by a movement of the block, and when the block moves to the one of the air outlet member and the air inlet member, the engagement surface of the block tightly abuts against an inner surface of the one of the air outlet member and the air inlet member.

A footwear insole including a ventilation mechanism for helping to reduce moisture, increase comfort, and/or reduce odor inside the footwear.

An article of footwear includes an upper member and a sole structure, with a sensor system connected to the sole structure. The sensor system includes a plurality of sensors that are configured for detecting forces exerted by a user's foot on the sensor. Each sensor includes two electrodes that are in communication with a force sensitive resistive material. Additionally, the sensor system may be provided on an insert that may form a sole member of the article of footwear. The insert may include an airflow system that includes one or more air chambers in communication with one or more air reservoirs through air passages extending therebetween. The insert may also have a multi-layered structure, with the airflow system provided between the layers.

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.
