[0002] At present, there is a kind of height increasing shoe on the market, which realizes the height increasing purpose by replacing different thickness insoles. For the wearer who has the height increasing demand, it is often expected that the greater the insole thickness is, the better, to achieve more significant height increasing effect.

[0003] However, in the actual use process, it is found that when the insole thickness is larger, especially the insole heel part as the thickest part, the part will generate larger compression force on the back of the shoe due to the outward deformation when wearing. This continuous compression is easy to cause the deformation problem of the back of the shoe, not only affects the overall appearance of the shoe, but also may reduce the service life of the shoe, and also affects the comfort and stability of wearing to some extent.

[0027] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] The following references are made Figures 1-5 The utility model is explained as follows:

[0029] Embodiment: a shoe with height-increasing function, comprising sole 1 and upper 2, the upper 2 is made of fabric, and the shoe is provided with height-increasing insole 3.

[0030] The rear end of the sole 1 extends upward to form wrapping part 4 wrapping the rear upper 2, and the thickness of the wrapping part 4 gradually increases from top to bottom, which can form a gradient support structure in the vertical direction. When the heel of the height-increasing insole 3 exerts pressure on the rear upper, the lower part of the wrapping part 4 with thicker structure can provide stronger support, and the transition design gradually thinning upwards can conform to the stress distribution of the rear upper, avoiding local stress concentration.

[0031] The width of the wrapping part 4 gradually increases from top to bottom. The support stability of the wrapping part 4 is enhanced from the horizontal dimension. The wider lower part forms a more stable connection basis with the rear end of the sole 1, and the narrowing width change upwards matches the contour of the rear upper, which can closely fit the outside of the rear upper and form horizontal support tension through the gradual change of width. This structure makes the wrapping part 4, when subjected to the pressure of the insole heel, can evenly disperse the pressure to different parts of the rear upper through the gradient change of its width and thickness, thereby effectively offsetting the deformation force of the insole on the rear upper.

[0032] When the wearer uses a thick insole, the pressure of the insole on the back of the heel of the shoe will first act on the upper part of the wrapping part 4. Since the upper part of the wrapping part 4 is thin and narrow in width, it has a certain elastic buffer space and can preliminarily absorb part of the pressure; as the pressure is transmitted downward, the wrapping part 4 gradually thickens and widens, and its rigid support capacity gradually increases, which can further disperse the pressure transmitted by the upper part to the connecting area of the entire wrapping part and the sole, and then transmit the force to the ground through the overall structure of the sole, so as to avoid the deformation of the back of the shoe caused by the concentrated pressure of the back of the shoe.

[0033] The wrapping part 4 is provided with a connecting part 5 penetrating the back of the shoe 2 and forming a detachable connection with the insole 3. The connecting part 5 is integrally arranged with the sole 1. The connecting part 5 is T-shaped, and the insole 3 is provided with a T-shaped connecting groove 6 penetrating the lower side and the rear side of the insole 3. The connecting part 5 is connected with the connecting groove 6 correspondingly.

[0034] The connecting part 5 is provided with three connecting parts respectively located at the rear side, left side and right side of the shoe 2, forming a three-dimensional fixed frame. When the connecting part 5 is inserted into the T-shaped connecting groove 6 of the insole, the rear end of the insole and the wrapping part 4 are rigidly connected through the connecting part 5, so that the back of the shoe is clamped between the rear end of the insole and the wrapping part 4.

[0035] The rear connecting part 5 directly bears the longitudinal pressure of the insole on the back of the heel, and the T-shaped structure is embedded in the connecting groove 6 of the rear side of the insole, forming longitudinal limiting; the left and right connecting parts 5 generate transverse restraining force on the two sides of the back of the shoe through the transversely extending structure. When the insole exerts a force to the back of the shoe due to the thickness, the clamping force formed by the three connecting parts 5 can generate a counteracting force in the longitudinal and transverse directions, so as to balance the force and offset the deformation force of the insole on the back of the shoe.

[0036] The distributed arrangement of the three connecting parts 5 makes the clamping force uniformly distributed on different parts of the back of the shoe. The rear connecting part 5 mainly bears the pressure of the heel area, and the left and right connecting parts 5 provide support to the edges of the back of the shoe. This multi-point fixing method can convert the concentrated pressure of the insole on the back of the shoe into dispersed clamping force, and then transmit the force to the entire sole structure through the cooperation of the wrapping part 4 and the insole, so as to avoid the deformation of the back of the shoe caused by excessive local stress.

[0037] The center of the rear end of the insole 3 is provided with a deformation groove 7 penetrating the upper and lower sides thereof. The deformation groove 7 guides the deformation direction of the insole, thereby reducing the extrusion on the back of the shoe.

[0038] The deformation groove 7 is a tapered structure with a small upper side and a large lower side.

[0039] When the insole is subjected to vertical pressure load, the material will have a tendency to expand in all directions. The traditional thick insole lacks deformation guiding structure, and the backward expansion deformation will directly act on the back upper, causing the back upper to be compressed and deformed.

[0040] When the upper part of the insole is subjected to pressure, the material will have a tendency to expand in all directions. The traditional thick insole lacks deformation guiding structure, and the backward expansion deformation will directly act on the back upper, causing the back upper to be compressed and deformed.

[0041] The rear end of the height-increasing insole 3 is provided with a split seam 8 penetrating through the upper and lower sides thereof, the split seam 8 being U-shaped and open forward, and the split seam 8 being arranged in a spaced manner with the edge of the height-increasing insole 3. The deformation transmission path of the insole is controlled, thereby reducing the extrusion on the back upper. When the insole is subjected to vertical pressure, the split seam 8 divides the rear end material into an inner side region and an outer side region. Due to the presence of the split seam 8, the deformation of the inner side region is difficult to be directly transmitted to the outer side region through material continuity - the deformation of the inner side material caused by pressure will be partially released into the U-shaped groove, and the deformation energy is limited within the inner side of the split seam; and the deformation of the outer side region needs to be transmitted inward through elastic deformation of the material due to the separation of the split seam, and the transmission process will consume part of the deformation energy, thereby reducing the extrusion on the outer side back upper.

[0042] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
