[0041] The working principle and use process of the present invention are as follows: the anti-skid bottom layer 1 is processed into an anti-skid bottom layer 1 with a specific texture through a rubber vulcanization molding process, and its thickness and hardness are ensured to meet the design requirements. The bottom frame 201 adopts an injection molding process to inject polyurethane material into a mold to form a shape that conforms to the arch curve of the foot. After cooling and solidification, appropriate post-treatment is performed to ensure its elastic performance, and a supporting air cushion 202 is placed inside. The strip-shaped inflatable belt 204 is clamped and installed in the side groove 203, and a bottom support pad 215 is placed. The bottom support pad 215 is stamped and formed by a precision mold, and massage protrusions and blood circulation channel simulations are accurately manufactured on its surface. The insole cushion 218 is placed on the top surface of the bottom support cushion 215, so that it is convenient to take out the insole cushion 218 and take out the battery 212 from the battery clip 216 for replacement and maintenance. The insole cushion 218 is made of a phase change material with heat storage and heat insulation properties. When the external environment temperature is low, the phase change material can absorb and store the heat emitted by the human foot, and then slowly release it to keep the foot warm and avoid blood stagnation caused by cold; when the external environment temperature is high, the phase change material can play a certain role in heat insulation, prevent the foot from overheating, maintain the comfort of the foot, and provide suitable temperature conditions for the smooth circulation of blood;

[0042] For the shoe upper 301 , the fabric blended from bamboo fiber and cotton fiber is cut into a desired shape and size, and then the various parts are stitched together through a sewing process to form a basic structure of the shoe upper 301 ;

[0043] When wearing shoes, the extrusion airbag 303 is inflated through the inflation tube 302, and the adjustment belt 306 is pulled, the anti-collision cushion 304 squeezes the toe position, and the comfort cushion 307 squeezes the heel position, and the position of the foot in the shoe is adjusted so that each top massage bead 310 is aligned with the Jiexi acupoint, the horizontal finger below the Jiexi acupoint, and the horizontal finger position two below the Jiexi acupoint, which is convenient for subsequent massage;

[0044] After walking, when sitting on a chair to rest, press the front switch 213, the front dual-purpose air pump 208 inflates the strip-shaped inflatable belt 204 and the flexible air column 205, the flexible air column 205 rises, the edge massage block 206 moves along the big toe to the little toe, and then the rear dual-purpose air pump 210 is started by the rear switch 214, the supporting air cushion 202 is reciprocatedly inflated and exhausted, the height difference between the supporting air cushion 202 and the top of the flexible air column 205 is increased, and the edge massage block 206 continues to massage, that is, the edge massage block 206 massages the area near the red and white flesh line of the foot. 06 Massage and squeeze, the front two-purpose air pump 208 repeatedly inflates and exhausts, and continuously massages, and the micro vibration motor 308 is also started, driving the massage plate 309 and the top massage beads 310 to massage, and massages the specific projection areas such as the Jiexi point, the horizontal finger below the Jiexi point, the horizontal finger below the Jiexi point, and the fourth and fifth toes at the intersection of the dorsum of the foot, so as to facilitate the need to clear the head and face in the dorsum projection area, promote the smoothness of the meridians in the holographic projection area of ​​the human body, so as to circulate the qi and blood in the feet and the whole body;

[0045] When the front dual-purpose air pump 208 and the rear dual-purpose air pump 210 are ventilating, the exchanged air will be filtered through the filter cotton strips to prevent dust and other debris from entering the support air cushion 202 and the flexible air column 205, and the nano silver wire 311 plays a bactericidal role, inhibiting the reproduction of microorganisms in the shoe and reducing the generation of odor;

[0046] The sole massage component 2 massages the sole of the foot, while the upper component 3 adjusts the foot position and massages the instep, making the massage more comprehensive and accurate, thereby improving the overall massage effect and comfort.

[0047] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
