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.

Biomechanically, a human foot operates as a lever of the second class during the motions involved with walking, running or jumping. Extending the toes during such motion increases the distance between the fulcrum and effort of the foot-lever and results in increased foot propulsion. Disclosed are apparatus and related methods of accomplishing extended toes during the motions involved with walking, running or jumping

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 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 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.

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 tactile feedback shoe sole for footwear comprising a main body that defines a toe portion, a middle portion and a heel portion. A first chamber filled with a fluid is disposed in one or more areas of the main body. A second chamber comprising a second chamber upper wall, a second chamber lower wall and projections is disposed in the arch region of the middle portion. Channels disposed between the first and the second chambers help in establishing fluidic communication between the first and second chambers. If the second chamber is compressed before the first chamber getting compressed, which is likely to happen when the feet of the user of the sole overpronate, the second chamber upper wall comes in contact with the second chamber lower wall and the projections are felt by the user in the arch region since the second chamber is not filled with the fluid.

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.
