A fatigue relief method using smart footwear and an operation method for a user terminal are provided. The fatigue relief method using smart footwear comprises: receiving the provision of pressure data or acceleration data measured while a user wears smart footwear and performs an exercise, wherein the smart footwear has at least one pressure sensor or acceleration sensor and a tactile element, which are installed therein; estimating the fatigue of the user by using the provided pressured data or acceleration data; selecting one of a plurality of vibration solutions on the basis of the estimated fatigue; and allowing the tactile element of the smart footwear to vibrate according to the selected vibration solution.

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 and the central ridge element is configured to contact the ground and move relative to the aperture.

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.

An insole having, a base layer, a top layer fixedly secured to the base layer, a middle layer comprised of the base layer and the top layer positioned between the base layer and the top layer, a pressure projection extending upwardly from within the middle layer and extending past an upper surface of the upper layer, the projection including a disc fixedly secured within the middle layer, an annular ring fixedly secured atop the disc, a circular metal insert fixedly secured atop the disc within the annular ring, the circular metal insert having a horseshoe-shaped aperture therein. The insole may also include projections either positioned proximate an inside arch and/or positioned proximate an outside arch. The insole may also comprise a projection positioned proximate to a midfoot region.

Systems and methods are disclosed including a tri-layer orthotic system having a heel portion and a forefoot portion to support respective heel and forefoot portions of a foot through at least a portion of a gait cycle. The tri-layer orthotic system can include an upper layer suspended over a mid-layer and a base layer to create a rear spring section, a mid-spring section, and a front spring section. A distal toe portion of the mid-layer can form the forefoot portion of the tri-layer orthotic system and a heel upper layer portion of the upper layer can form the heel portion of tri-layer orthotic system.

A shoe insole apparatus capable of buffering and massaging includes a pad part laid on a bottom surface inside a shoe and a buffering part which adheres to a portion including a central portion to a heel portion of the pad part and absorbs shock applied to a heel of a wearer, wherein the buffering part includes a body part of which a height decreases from the heel portion of the pad part toward a ball portion, a buffering groove which is positioned in an upper portion of the heel portion of the pad part, passes through the body part, and is formed in a quadrangular shape, and a plurality of buffering plates which are formed to extend to connect two inner surfaces facing each other among inner surfaces of the buffering groove and are in contact with the heel of the wearer.

A blood pressure lowering training device comprises a head frame unit corresponding to a user's head shape, an audio stimulation unit for broadcasting binaural beats with frequency following response to both ears of the user, a display unit including a display module for displaying a virtual image and blood pressure information and a blood pressure measurement module for measuring blood pressure, and a control unit electrically connected with the audio stimulation unit and the display unit, so that the hypertensive patient can perform a variety of adjustable blood pressure lowering training in one use process, and effectively improve the use intention of the hypertensive patient.

A somatosensation and proprioceptor stimulation surface configured to stimulate rapid-firing nerves in the receptive field of a user's glabrous skin. The somatorsensation and proprioceptor stimulation surface includes a plurality of protuberances disposed thereupon, each protuberance sized and spaced apart appropriately to impress the receptive field when pressed in contact with the glabrous skin of the user. Each protuberance widens from an apex toward a base whereby increased pressure applied to the surface increases an area of contact and stimulation by applying stimulation over a larger area of skin. The protuberances are spaced apart to maximize stimulation of rapid firing nerves while lessening overstimulation. The somatosensation and proprioceptor stimulation surface is rendered in the form of a mat or floor covering and alternatively as an insole for wear in a user's shoes.

The application provides for a vibrating foot massager that resembles a common shoe. This vibrating foot massager has a number of vibrating motors which can be placed in a variety of combinations within the sole of the shoe. Preferably, the vibrating foot massager will be equipped with a power source so the entire device will be portable. This will enable a user to enjoy the benefits of receiving a foot massage while on the go. The vibrating foot massager is also equipped with a power switch such that when the motors are not in use, the device operates as a functional shoe.

An insole/sole structure contains: a top pad, two massage column modules, a form pad, and a bottom pad. The top pad includes at least one accommodation groove. A respective one of the at least one massage column module includes a holding portion and multiple flexible massaging columns. The respective one massage column module is connected on the top pad by using the holding portion. The multiple flexible massaging columns are held on the holding portion to correspond to a profile of a respective one accommodation groove. A profile of the foam pad and a profile of the bottom pad correspond to a profile of the top pad, such that when the foam pad and the bottom pad are connected, the foam pad and the bottom pad are closed, and the respective one massage column module is limited between the top pad and the foam pad.
