[0030] As shown Figures 1 - 5 in the figure, this embodiment discloses an adjustable height-increasing sole, which includes a sole part 1 and a heel part 2. The sole part 1 is connected to the heel part 2. It further includes an adjustable foot pad 3. The adjustable foot pad 3 is detachably arranged in the heel part 2. The adjustable foot pad 3 can change its own thickness to achieve the function of adjusting the height increase. The adjustable foot pad 3 does not directly contact the human sole. After each height adjustment, the sole always contacts the end face of the fixed heel part 2, and the comfort of wearing and using is higher.

[0031] Furthermore, the heel part 2 includes an upper shoe plate 21, a lower shoe plate 22 and a flexible part 23. One end of the upper shoe plate 21 is connected to one end of the lower shoe plate 22 to form a stackable double-layer structure. A space for accommodating the adjustable foot pad 3 is formed by opening between the upper shoe plate 21 and the lower shoe plate 22. The flexible part 23 is arranged at the connection of the upper shoe plate 21 and the lower shoe plate 22. Among them, the upper shoe plate 21 and the lower shoe plate 22 form an opening on the side facing outside the insole. The flexible part 23 is used to strengthen the connection of the upper shoe plate 21 and the lower shoe plate 22 and improve the service life of repeated folding. Among them, the adjustable foot pad 3 includes a bladder 31, an inflation port 34 and a bladder plug 35. The inflation port 34 is communicated with the inside of the bladder 31. The bladder plug 35 can block the inflation port 34. A cavity is arranged inside the bladder 31. By filling gas into the cavity through the inflation port 34, the thickness of the bladder 31 can be changed, thereby changing the height increase of the height-increasing insole. The bladder plug 35 is connected to the bladder 31 to prevent the bladder plug 35 from falling off, which is convenient for closing the bladder 31 after inflation for use.

[0032] Preferably, the flexible part 23 is a PU sheet. TPU has excellent bonding performance, abrasion resistance, flexure resistance and anti-aging characteristics. Using it here can strengthen the connection of the upper shoe plate 21 and the lower shoe plate 22 and prevent the connection from breaking after repeated folding.

[0033] Furthermore, the front half of the flexible part 23 overlaps with the upper shoe plate 21, and the rear half of the flexible part 23 overlaps with the lower shoe plate 22, which improves the connection strength between the flexible part 23 and the shoe plate.

[0034] Furthermore, the adjustable foot pad 3 further includes a first protrusion 32 and a first groove 33. Both the first protrusion 32 and the first groove 33 are arranged on the outer wall of the bladder 31, and can be used to connect the adjustable foot pad 3 and combine the upper shoe plate 21 and the lower shoe plate 22.

[0035] Preferably, a plurality of first protrusions 32 are distributed in a triangular shape on the outer wall of the bladder 31, so that the connection between the upper shoe plate 21, the lower shoe plate 22 and the bladder 31 is highly firm.

[0036] Further, the upper shoe plate 21 is provided with a second protrusion 211 and a second groove 212, and the lower shoe plate 22 is provided with a third protrusion 221 and a third groove 222. The second protrusion 211 can be buckled with the third groove 222, and the second groove 212 can be buckled with the third protrusion 221 for connecting the upper shoe plate 21 and the lower shoe plate 22.

[0037] Further, the second protrusion 211 and the third protrusion 221 can be buckled with the first groove 33, and the second groove 212 and the third groove 222 can be buckled with the first protrusion 32 for connecting the upper shoe plate 21, the lower shoe plate 22 and the bladder 31.

[0038] Preferably, the other end of the upper shoe plate 21 is snap-connected to the other end of the lower shoe plate 22. The front cross-section of the first protrusion 32 is larger than the rear cross-section, so that each protrusion and groove form an inverted buckle structure, which improves the connection strength between the shoe plates and between the shoe plates and the bladder 31, prevents the shoe plates from separating from the bladder 31 during use, and can be disassembled and used repeatedly. The first protrusion 32, the second protrusion 211 and the third protrusion 221 have the same structure.

[0039] The use process of the adjustable height-increasing shoe sole is as follows:

[0040] According to the use requirements, select whether to install the adjustable foot pad 3. When not using the height-increasing function, directly press the upper shoe plate 21 and the lower shoe plate 22 so that the second protrusion 211 and the third protrusion 221 are respectively buckled with the second groove 212 and the third groove 222; when using the height-increasing function, adjust the height according to the use needs, fill an appropriate amount of gas into the bladder 31 of the adjustable foot pad 3, so that the bladder 31 expands to a certain thickness, and after sealing the bladder 31, insert it between the upper shoe plate 21 and the lower shoe plate 22, so that the protrusions and grooves on the outer wall of the bladder 31 are respectively buckled with the protrusions and grooves on the upper shoe plate 21 and the lower shoe plate 22.
