A method for interlocking a shoe sole can provide the ability for the shoe sole to be attached or removed. For example, a shoe wearer may want the ability to change his or her shoe soles for aesthetic purposes. The shoe sole can also comprise additional functionality for the shoe wearer. For example, a method of also using the shoe sole as storage is discussed herein.

An interchangeable foot therapy massager including a base defining a cavity having a first section having a first diameter and a second section having a second diameter greater than the first diameter, an insert including a pair of opposing sides and configured to be received within the first and second sections of the cavity, the insert including a head for contacting the foot of the user, a lip for engaging the second section of the cavity, and defining a space configured to allow for inward flexure, wherein applying force to the sides of the insert causes the insert to flex inwardly, removing force from the sides of the insert causes the insert to flex outwardly, and when the insert flexes outwardly the at least one lip engages the second section of the cavity.

A sole of a shoe has a plurality of lower protrusions and a plurality of upper protrusions arranged at least at a portion of the sole corresponding to a forefoot of a wearer of the shoe. A support includes a planta rest that is arranged in an internal space surrounded by a shoe upper and bridges between a position of the shoe upper corresponding to a medial side of the foot of the wearer of the shoe to a position of the shoe upper corresponding to a lateral side of the foot of the wearer of the shoe in a foot width direction. The planta rest is configured to receive a portion of the planta of the foot of the wearer of the shoe near a base of metatarsal bone and lift the base of metatarsal bone above the sole.

Disclosed herein are systems and methods for transforming footwear. A footwear system includes one or more portions configured in a first profile. The footwear system includes one or more sensors configured to generate a value based on a surface in contact with at least one of the one or more portions. The footwear system includes an actuator configured to change, responsive to determining that the value satisfies a profile configuration condition, a configuration of the one or more portions from the first profile to a second profile in accordance with the surface.

An article of footwear may include a sole structure fixedly attached to an upper defining an internal cavity configured to receive a foot of a wearer. The sole structure may include an exposed outer member configured to contact the ground, the exposed outer member including a first aperture, and a sensory feedback member disposed at least partially within the first aperture in the outer member, the sensory feedback member including a first end and a second end. The first end of the sensory feedback member may include a projection extending through the first aperture and configured to contact the ground. In addition, the second end of the sensory feedback member may include a plurality of flexible bristles extending through a portion of the sole structure and exposed to the internal cavity.

An article of footwear including a sole structure attached to an upper defining an internal void configured to receive a foot of a wearer is described. The sole structure includes a sole body portion having a central ridge element located in an aperture in the sole body portion. The central ridge element has a bottom surface configured to contact the ground and move vertically within the aperture. The movement of the central ridge element pushes a top surface of the ridge element attached to a portion of the upper against the foot of the wearer. The central ridge element is arranged approximately centrally between lateral and medial sides in the forefoot region of the sole structure. The central ridge element provide sensory feedback about lateral movement and to the foot of the wearer.

The present invention refers to a footwear consisting of an upper portion and a sole, wherein the upper portion is provided with a soft and flexible deconstructed plantar area able to allow the foot to rest on it, once the footwear has been worn, and the sole is fixed to the upper portion below the plantar area and is provided with a plurality of flexible bearings, arranged in correspondence with respective sensitive areas for the plantar reflexology massage.

A method for making an electrotherapeutic sole, where the electrotherapeutic sole includes of nitrile-butadiene rubber (38%42% by weight), conductive carbon black (37%42% by weight), a softening oil (14%17% by weight), a processing aid (3%5% by weight), and an accelerant (1%2% by weight) and has a top portion protrudingly provided with a plurality of electrode protuberances that correspond in positions to the acupoints in a human sole; the electrotherapeutic sole is also provided with a socket, thereby an electrotherapeutic pulse output terminal inserted into the socket can send the electrotherapeutic pulses generated by an electrotherapeutic pulse generator sequentially through the socket and the conductive carbon black in the electrotherapeutic sole to the tips of the electrode protuberances to massage the corresponding acupoints in the human sole.

A system for the treatment of a foot includes a waterproof boot capable of receiving an insert with a plurality of nozzles and a dispensing ring. The insert can receive a human foot to be treated therein. The plurality of nozzles and dispensing ring are each in fluid communication with a pump, when energized, delivers a continuous flow of a fluid therethrough. In a preferred embodiment, the fluid is a medicinal, toxin extracting fluid.

The present invention regards a sole for a sport shoe, work shoe or leisure shoe including a main body having a lower layer delimiting a surface, lower during use, set to come into contact with the ground and an upper layer set to come into contact with a foot of a user or to support from the bottom, during use, an insole.
