[0025] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model and cannot be understood as limiting the utility model. The specific technology or condition not noted in the embodiments is carried out according to the technology or condition described in the literature in the field or according to the product manual.

[0026] The utility model is further described in combination with the drawings and specific embodiments.

[0027] Embodiment 1:

[0028] For the convenience of understanding, Figure 1 The schematic view of the shoe and the human foot wearing into the shoe is shown, and the human foot 4 includes the instep 41, and the thickness and width of the foot at the position of the instep 41 are different for different people, even if the same length and size of shoes are worn, it is very likely that the foot is squeezed or loose at the position of the instep 41, and similarly, there is a similar problem at the position of the heel 42. The shoe 100 includes the upper 1 and the sole 2, wherein the upper 1 further includes the inner layer 5 and the outer layer 6, and the shoe 100 only shows one type, specifically a shoe with a tongue, and the shoelace of the shoe is not shown in the figure, and the shoe 100 can have a shoelace or not have a shoelace, and it can be understood that other types of shoes can also be applied in the embodiment. For the convenience of description, the position of the shoe 100 in the static use state is described as the described position.

[0029] As Figure 2 shown, the skeleton with thermoplasticity is embedded in the upper 1, and the skeleton includes the first skeleton 31 and the second skeleton 32, and the first skeleton 31 and the second skeleton 32 are both in sheet structure and are embedded between the inner layer 5 and the outer layer 6 of the upper 1. Among them, the first skeleton 31 is correspondingly arranged at the position of the instep 41, that is, the left and right side positions of the upper 1, and the second skeleton 32 is correspondingly arranged at the position corresponding to the heel 42, that is, the rear end position of the upper 1. The first skeleton 31 and the second skeleton 32 both extend in the height direction of the shoe 100 to support the upper 1, and the bottom ends of the first skeleton 31 and the second skeleton 32 are fixedly connected with the bottom of the upper. The height direction of the shoe 100 is further explained in the embodiment as the extension direction from the bottom of the upper 1 to the top of the upper 1, and the first skeleton 31 and the second skeleton 32 as the hard structure embedded in the soft upper 1 can support the bending structure of the upper 1 itself, that is, the deformation of the first skeleton 31 and the second skeleton 32 can also cause the deformation of the upper 1.

[0030] See Figure 2 and Figure 3 The first frame 31 is positioned on the instep 41 of the foot 4 and extends partially around the instep 41. The direction around the instep 41 is as follows: Figure 1 As shown in the Z0-Z1 direction, the first frame 31 can provide almost complete support for the parts of the upper 1 corresponding to the instep 41 on both sides. In this embodiment, the upper 1 also includes a U-shaped tongue groove 36 at the upper end for accommodating the tongue 37. The first frame 31 includes a left first frame 311 located on the left side of the tongue groove 36 and a right first frame 312 located on the right side of the tongue groove 36. The upper ends of the left first frame 311 and the right first frame 312 are fixedly connected to the width edge 33 of the tongue groove 36. During manufacturing, the inner layer 5 and the outer layer 6 are stacked to form the upper 1 (there may be other layers between the inner layer 5 and the outer layer 6, depending on the shoe). Depending on the manufacturing process of the shoe, the inner layer 5 and the outer layer 6 are connected at the width edge 33 of the tongue groove 36, for example, by sewing. At this time, the left first skeleton 311 and the right first skeleton 312 inserted between the inner layer 5 and the outer layer 6 can also be fixed to the width edge 33 of the tongue groove 36 by means of the connection process of the inner layer 5 and the outer layer 6. For example, the left first skeleton 311 and the right first skeleton 312 are also sewn to the width edge 33 of the tongue groove 36, thereby ensuring that the first skeleton 31 will not easily shift.

[0031] Both the left first frame 311 and the right first frame 312 include a first extension 313 and a second extension 314 extending downward from the first extension 313. The first extension 313 is fixedly connected to the width edge 33 of the tongue groove 36, and the second extension 314 is fixedly connected to the bottom 34 of the upper. The first extension 31 extends along the width edge 33 and connects to it, making the connection between the first frame 31 and the width edge 33 more stable. The second extension 314 extends downward around the instep 41 to support the upper 1 in the height direction. At the same time, the second extension 314 is connected to the bottom 34 of the upper, further ensuring that the first frame 31 will not easily shift. In this embodiment, the second extension 314 is a strip structure with multiple extensions spaced apart along the length of the shoe. This saves material. In other embodiments, the second extension 314 can also be a single sheet structure.

[0032] The second skeleton 32 is embedded into the upper 1 through a manufacturing method similar to that of the first skeleton 31, which will not be described in detail here.

[0033] The framework in this embodiment is made of low-temperature thermoplastic material, such as polyisoprene (gutta-percha), which has good hardness and rigidity after cooling. In particular, the framework with thermoplasticity can be deformed by heating, such as heating and softening the framework by blowing hot air, hot water soaking, etc. After the customer purchases the shoes, the framework is heated and softened, and then the foot is inserted into the inside of the shoes, and the shoes are stretched or compressed to the appropriate shape, so as to change the degree of tightening and opening of the upper 1, so that the shoes 100 are more suitable for the foot, and finally wait for the framework to cool and set to obtain shoes suitable for different foot types.

[0034] In this embodiment, the left first framework 311 and the right first framework 312 are disconnected, and are inserted into the left side and the right side of the upper 1 respectively during manufacturing, as shown in Figure 4 and Figure 5 A variant of this embodiment is shown, in which the left first framework 311' and the right first framework 312' are fixedly connected as a whole by the connecting part 35 at the front end of the tongue groove 36, and during manufacturing, only one whole first framework needs to be inserted between the inner layer 5 and the outer layer 6 of the upper 1 from the front end of the tongue groove 36, although the structure of the first framework is more complex, but it is more convenient during manufacturing. At the same time, the integrally connected first framework is less likely to shift.

[0035] It can be predicted that the specific shape of the framework is not limited, and for the first framework 31, as long as it has a part arranged at a position corresponding to the instep of the human foot and extends in a direction around the instep of the human foot, and for the second framework 32, as long as it has a part arranged at a position corresponding to the heel of the human foot. The first framework 31 and the second framework 32 can both be frameworks with a tortuous shape, or can be frameworks with wrinkles to obtain a larger expansion area, as long as the framework can change the degree of tightening or opening of the upper 1 by the thermoplastic deformation of the framework.

[0036] Embodiment 2:

[0037] Referring to Figure 6As shown, the shoe in the embodiment includes a sole 12 and an upper 11, and the upper 11 is divided into an inner layer and an outer layer. The shoe in the embodiment is a shoe without a tongue, and more specifically, the upper 11 completely covers the instep of a human foot. A first skeleton 130 with thermoplasticity in the form of a sheet is embedded between the inner layer and the outer layer of the upper 11, and the first skeleton 130 includes a plurality of first skeleton monomers 13 arranged at intervals in the length direction of the shoe to form the first skeleton 130. The first skeleton monomers 13 extend in the direction around the instep of the human foot and continuously extend from the left end of the upper bottom 16 to the right end of the upper bottom 16, and the left and right two bottom ends 14 of the first skeleton monomers 13 are fixedly connected to the left and right ends of the upper bottom 16, respectively, which can be stitching or adhesion. The design of the first skeleton monomers 13 extending in the direction around the instep of the human foot and continuously extending from the left end of the upper bottom 16 to the right end of the upper bottom 16 can completely cover the instep of the human foot, and has higher fit. The number of the first skeleton monomers 13 is not fixed, and only one first skeleton monomer 13 can be arranged, as long as the first skeleton 130 can cover the instep of the human foot and can change the degree of tightening or opening of the upper 11 to fit the size of the human foot.

[0038] To solve the problem that the first skeleton monomers 13 embedded between the inner layer and the outer layer of the upper 11 slide during the wearer's travel, the first skeleton monomers 13 are inserted into the embedded channels 15 between the inner layer and the outer layer of the upper 11, which can limit the first skeleton monomers 13. The embedded channels 15 can be formed in advance during the molding of the upper 11, for example, after the inner layer and the outer layer of the upper 11 are laminated, a plurality of embedded channels 15 are formed by arranging a plurality of parallel stitching lines, and then the first skeleton monomers 13 are inserted into the embedded channels 15, and the two ends of the first skeleton monomers 13 are connected to the left and right ends of the upper bottom 16. The skeleton in the embodiment is completely embedded between the inner layer and the outer layer of the upper, which can better hide the skeleton and make the upper more beautiful.

[0039] Embodiment 3:

[0040] Referring to Figure 7As shown, in the embodiment, a first skeleton with thermoplastic sheet shape is embedded between the inner layer 21 and the outer layer 22 of the vamp, a plurality of sockets 28 are formed between the inner layer 21 and the outer layer 22, the sockets 28 are arranged on the left part of the vamp and the right part of the vamp, a plurality of first skeleton monomers 23 are inserted into the sockets 28, the plurality of first skeleton monomers 23 are arranged at intervals in the length direction of the vamp, the plurality of first skeleton monomers 23 on the left part of the vamp form a left first skeleton, and the plurality of first skeleton monomers 23 on the right part of the vamp form a right first skeleton. The lower end 26 of the first skeleton monomer 23 is fixedly connected with the lower part 25 of the vamp, and the upper end of the first skeleton monomer 23 is provided with a perforation 27 through which the shoelace 24 passes, that is, the first skeleton monomer 23 also simultaneously forms a connecting part of the shoelace 24.

[0041] The way of arranging the pocket-shaped sockets 28 on the vamp makes the first skeleton easier to install.

[0042] In the modified example, the upper ends of the first skeleton monomers 23 on the same side can be integrally connected.

[0043] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as the limitation of the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments in the range of the utility model without departing from the principles and purposes of the utility model.
