First Embodiment

[0043] As shown in FIG. 1 to FIG. 5, the upper includes a first upper 1 and a second upper 2. At least one pin buckle 3 is provided at the first upper 1, and at least one woven strap 4 is provided at the second upper 2. The distance between the first upper 1 and the second upper 2 is adjusted by inserting the pin 32 into a different woven perforation 41, and thus the tightness of the upper is adjusted. The bottom of the first upper 1 is fixed to the left side of the sole 5, and the bottom of the second upper 2 is fixed to the right side of the sole 5. The first upper 1 and the second upper 2 are elastic. Optionally, the second upper 2 and the woven strap 4 are integral, that is, the second upper 2 is also a woven structure, and multiple woven perforations 41 are formed in the second upper 2.

[0044] Since the second upper 2 has the woven perforations 41, the second upper 2 would not completely block the air circulation; thus, the shoe has better permeability, and is not easy to make the user feel stuffy. Furthermore, since the second upper 2 and the at least one woven strap 4 are integrally formed, the problem of fixed connection between different materials is avoided, and the strength of the shoe is effectively improved. The at least one woven strap 4 extends from the second upper 2 to being above the first upper 1, and is connected with the at least one pin buckle 3 arranged on the first upper 1.

[0045] It should be noted that, in some implementations, the second upper 2 may not be woven, but may be made of materials such as leather and polyurethane (PU), as long as the at least one woven strap 4 is provided on the second upper 2. Optionally, the first upper 1 is also woven, and multiple woven perforations are formed therein.

[0046] As an example, the adjustable structure includes two woven straps 4, and the two woven straps 4 are distributed in a longitudinal direction. It should be noted that, in some implementations, the adjustable structure may include multiple woven straps 4, and it is not limited to two. Accordingly, there are two pin buckles 3. Each pin buckle 3 cooperates with one woven strap 4 in the way mentioned above. The first upper 1 is detachably connected with the woven straps 4 through the respective pin buckles 3.

[0047] The shoe in the above embodiment is provided with multiple woven straps distributed in the longitudinal direction, so that the user can adjust the width of the upper at different positions as required, to adapt to different foot shapes. In addition, the integral woven structure of the second upper and the woven strap is conductive to providing a more breathable upper, which offer a more comfortable user experience.

[0048] For ease of understanding, as shown in FIG. 1, a first direction A and a second direction B are marked, the first direction A is from the back to the front, and the second direction B is from right to left.

[0049] It should be noted that, in some implementations, the structure of the pin buckle 3 is as shown in FIG. 6a. The pin buckle 3 includes a buckle 31 and a pin 32. The buckle 31 is of an annular structure. One end of the pin 32 is rotatably connected to the buckle 31, and the other end of the pin 32 is used to pass through the woven perforation 41. The buckle 31 is fixed on the upper. The buckle 31 includes a first rib 311, a second rib 312, a third rib 313, a fourth rib 314 and a fifth rib 315. The first rib 311, the second rib 312, the third rib 313 and the fourth rib 314 define a ring. The fifth rib 315 is located below the first rib 311, and a gap channel G is defined between the fifth rib 315 and the first rib 311 for the woven strap 4 to pass therethrough. The pin 32 is rotatably connected to the fifth rib 315. In some other implementations, as shown in FIG. 6b, the pin buckle 3 includes a buckle 31 and a pin 32. The buckle 31 includes a first rib 311, a second rib 312, a third rib 313, a fourth rib 314 and a sixth rib 316. The first rib 311, the second rib 312, the third rib 313 and the fourth rib 314 define a ring. One end of the sixth rib 316 is connected to the third rib 313, and the other end of the sixth rib 316 is connected to the fourth rib 314. The pin 32 is rotatably connected to the first rib 311 or the sixth rib 316 of the buckle. It should be noted that the shape of the pin buckle 3 is not limited thereto, and it may be adjusted as required.

[0050] When the user needs to adjust the width of the upper, the pin 32 may be released from the woven perforation 41 of the woven strap 4. Then, the position of the woven strap 4 is adjusted so that the pin 32 is positioned at an appropriate woven perforation. After this adjustment, the woven strap 4 is inserted into the buckle 31, and the pin 32 passes through a woven perforation 41 to establish a connection between the pin 32 and the woven strap 4.

Second Embodiment

[0051] The adjustable structure further includes a first connecting strap 42. One end of the first connecting strap 42 is fixed to one of the left side and the right side of the sole 5, and one end of the woven strap 4 is fixed to the other of the left side and the right side of the sole 5. The pin buckle 3 is arranged on the first connecting strap 42. When the woven strap 4 is passed through the buckle 31, the pin 32 can pass through a woven perforation 41 of the woven strap 4 to prevent the woven strap 4 from being separated from the buckle 31. The pin 32 may be inserted into a different woven perforation 41, so as to adjust the connection position at which the first connecting strap 42 is connected with the woven strap 4, and thus adjust the tightness of the upper.

[0052] As shown in FIG. 7 to FIG. 11, the upper includes a first upper 1 and a second upper 2. The adjustable structure includes a first connecting strap 42, a first woven strap 43 and the pin buckle 3. The first connecting strap 42 and the first woven strap 43, under cooperation of the sole 5, wrap the first upper 1 and the second upper 2. One end of the first connecting strap 42 is fixed to the left side of the sole 5, and one end of the first woven strap 43 is fixed to the right side of the sole 5. The pin buckle 3 is arranged on the first connecting strap 42. A gap is defined between the second rib 312 and the first connecting strap 42 for the first woven strap 43 to pass through. When the first woven strap 43 is passed through the buckle 31, the pin 32 can pass through a woven perforation 41 of the first woven strap 43 to prevent the first woven strap 43 from being separated from the buckle 31. The pin 32 may be inserted into a different woven perforation 41, so as to adjust a connection position at which the first connecting strap 42 is connected with the first woven strap 43, and thus tighten or loosen the first upper 1 and the second upper 2. The bottom of the first upper 1 is fixed to the left side of the sole 5, and the bottom of the second upper 2 is fixed to the right side of the sole 5. The first upper 1 and the second upper 2 are elastic.

[0053] Optionally, the first connecting strap 42 is a woven strap, and it has woven perforations 41.

[0054] The above arrangement has advantages as follows. The materials of the first upper 1 and the second upper 2 can be adjusted as required. For example, if the shoe is expected to be more ventilated, the first upper 1 and the second upper 2 may be in a woven structure with the woven perforations 41, so that it is more ventilated. If it is desired to set a pattern(s) on the first upper 1 and the second upper 2 to make the shoe more beautiful, the first upper 1 and the second upper 2 may use cloth or PU and other materials (in some embodiments, an elastic sheet may be optionally provided in the interior) to facilitate spraying of patterns on the first upper 1 and the second upper 2.

[0055] Optionally, the first upper 1 and the second upper 2 are partially overlapped to define an arch for the user's foot to pass therethrough.

[0056] When the user desires to adjust the width of the upper, it may first release the pin 32 from the woven perforation 41 so that the first connecting strap 42 and the first woven strap 43 can be detached from each other. Next, the first woven strap 43 is passed through the buckle 31 to adjust the degree of tightening or loosening between the first upper 1 and the second upper 2. After the ideal position is reached, the pin 32 can pass through a woven perforation 41 of the first woven strap 43 to fix the relative position of the first connecting strap 42 and the first woven strap 43, thereby locking the degree of closure between the first upper 1 and the second upper 2 to provide a relatively fixed upper.

[0057] Optionally, as shown in FIG. 12 and FIG. 13, the shoe may also be provided with an arched upper in front of the first upper 1 and the second upper 2, for the user's foot to pass therethrough.

Optionally, the fourth upper strap 69 and the fifth upper strap 70 are elastic.

[0068] Since the upper is composed of the upper straps, and the woven strap has woven perforations for ventilation, the ventilation performance of the entire upper is greatly enhanced.

Fifth Embodiment

[0069] As shown in FIG. 21 to FIG. 25, the upper includes a first front upper 81 and a rear upper strap 82. The rear upper strap means a strap located at the rear upper, which may be for example a heel strap. The rear upper strap 82 is located behind the first front upper 81. A fourth woven strap 83 is further included. The rear upper strap 82 is provided with the pin buckle 3, and the fourth woven strap 83 is detachably connected to the rear upper strap 82 via the pin buckle 3 to adjust the tightness of the upper.

[0070] As an example, the front end of the fourth woven strap 83 is connected to the first front upper 81, and the rear end of the fourth woven strap 83 cooperates with the pin buckle 3 located on the rear upper strap 82. As an example, the rear upper strap 82 and the fourth woven strap 83 are respectively connected to the left side and the right side of the first front upper 81, and the rear upper strap 82 and the fourth woven strap 83 are connected through the pin buckle 3. The connected rear upper strap 82 and the fourth woven strap 83 surround the left side, the right side and the back side of the heel, and then the width of the upper at the heel position can be adjusted by the rear upper strap 82 and the fourth woven strap 83, so as to adapt to different foot shapes.

[0071] It should be noted that, one end of the rear upper strap 82 is connected to one of the left side and the right side of the first front upper 81, and the other end of the rear upper strap 82 is passed through the sixth rib 316 of the pin buckle 3 and then folded back to define a ring for the sixth rib 316 to pass therethrough.

The bottom end of the second connecting strap 84 is fixed to one of the left side and the right side of the sole 5, and the bottom end of the fifth woven strap 85 is fixed to the other of the left side and the right side of the sole 5. The first front upper 81 is configured to cover at least a part of the instep, and the second connecting strap and the fifth woven strap are arranged on the first front upper 81. The pin buckle 3 is arranged on the second connecting strap 84. When the fifth woven strap 85 is passed through the buckle 31 arranged on the second connecting strap 84, the pin 32 of the pin buckle 3 arranged on the second connecting strap 84 can pass through a woven perforation 41 of the fifth woven strap 85 to prevent the fifth woven strap 85 from being separated from the buckle 31 of the second connecting strap 84. The pin 32 may be inserted into a different woven perforation 41 to change a connection position at which the second connecting strap 84 is connected with the fifth woven strap 85, so as to change the tightness of the first front upper 81. After the second connecting strap 84 and the fifth woven strap 85 are connected, they wrap the first front upper 81. When the user desires to shrink the first front upper 81, the second connecting strap 84 and the fifth woven strap 85 may be tightened to tighten the first front upper 81. When the user wishes to expand the first front upper 81, the user may loosen the second connecting strap 84 and the fifth woven strap 85, so that the first front upper 81 can expand under the action of an external force.

[0074] Optionally, the second connecting strap 84 is a woven strap having woven perforations 41.

Seventh Embodiments

[0075] As shown in FIG. 29, the upper includes a first heel strap 91, a second heel strap 92 and a third upper 93. A heel strap means a strap located at a rear side of a side. The bottom end of the first heel strap 91 is fixed to one of the left side and the right side of the sole 5, and the bottom end of the second heel strap 92 is fixed to the other of the left side and the right side of the sole 5. The third upper 93 is located in front of the first heel strap 91 and the second heel strap 92.

Eighth Embodiment

[0076] The fourth upper 102 is part or all of the upper of the shoe. As shown in FIG. 30 and FIG. 31, the fourth upper 102 is a partial upper such as an ankle strap of a sandal or a heel strap, and the adjustable structure further includes a fourth connecting strap 101. One end of the fourth connecting strap 101 is fixed to one of the left side and the right side of the fourth upper 102, and one end of the woven strap 4 is fixed to the other of the left side and the right side of the fourth upper 102. The pin buckle 3 is arranged on the fourth connecting strap 101. When the woven strap 4 is passed through the buckle 31, the pin 32 can pass through a woven perforation of the woven strap 4 to prevent the woven strap 4 from being separated from the buckle 31. The pin 32 may be inserted into a different woven perforation 41 to adjust the connection position at which the fourth connecting strap 101 is connected with the woven strap 4, so as to adjust the tightness of the fourth upper 102. Of course, in some optional implementations, the design of the upper may be adjusted as shown in FIG. 32 and FIG. 33, in which the woven strap 4 also serves as a part of the upper to wrap around the user's foot. In another embodiment of the present disclosure, as shown in FIG. 32 and FIG. 33, the fourth upper 102 may be a whole shoe upper. In this case, one end of the fourth connecting strap 101 is fixed to one of the left and right sides of the fourth upper 102, and the pin buckle 3 is arranged on one end of the fourth connecting strap 101 away from the fourth upper 102. The woven strap 4 is arranged opposite the fourth connecting strap 101. One end of the woven strap 4 is fixed to the fourth upper 102 at a position including, but is not limited to, a side of the fourth upper 102 or an edge of a topline defined by the fourth upper 102. When the woven strap 4 is passed through the buckle 31, the pin 32 can pass through the woven perforation of the woven strap 4 to prevent the woven strap 4 from being separated from the buckle 31. The tightness of the fourth upper 102 is adjusted by inserting the pin 32 into different woven perforations 41 to adjust the connection position between the fourth connecting strap 102 and the woven strap 4.

[0077] In each of the above embodiments, the perforation size of the woven strap 4 is 0.5-3 mm. A spacing between the perforations is 0.5-1 mm. The woven structure of the woven strap is woven from braided strips or braided wires which have sufficient strength by themselves. The braided strips or braided wires may be made of cotton, linen, yarn, nylon, polyester, spandex, or the like. It should be noted that each of the first woven strap 43, the second woven strap 65, the third woven strap 66, the fourth woven strap 83, the fifth woven strap 85, the sixth woven strap 94 and the seventh woven strap 96 is the woven strap 4 having the woven perforations 41 thereon. It should also be noted that the woven strap 4 may have a first woven area 44 and a second woven area 45, and the first woven area 44 and the second woven area 45 are different from each other. The two woven areas are different from each other in one or more of the material, the size of the woven perforations, the pattern and the spacing between woven perforations, as shown in FIG. 34 to FIG. 38. For example, the woven perforations 41 of the first woven area 44 are larger than the woven perforations 41 of the second woven area 45 in size, the spacing between the woven perforations (41) of the first woven area (44) is large, and the spacing between the woven perforations (41) of the second woven area (45) is relatively small. The large woven perforations 41 in the first woven area 44 are used to connect with the pin buckle 3, and because the woven perforations 41 are distributed in a net form, not only good ventilation effect can be maintained, but also multiple different positions are provided for the pin 3 to pass therethrough, so as to achieve accurate adjustment of the tightness of the upper. The small woven perforations in the second woven area 45 are mainly used to maintain the structural strength of the woven strap 4. Through the above arrangement, the woven strap 4 can not only ensure good ventilation effect and adaptability to human feet, but also ensure the structural strength of the woven strap 4, and the woven strap 4 is not easily broken after being passed by the pin 3 many times. Alternatively, the spacing between the woven perforations 41 of the first woven area 44 is larger, and the spacing between the woven perforations 41 of the second woven area 45 is relatively smaller; as such, different patterns or styles are defined on the woven strap to present a more beautiful effect. The woven perforations 41 having large spacing in the first woven area 44 are used to connect with the pin buckle 3, and because the woven perforations 41 are distributed in a net form, good ventilation effect can be maintained. The woven perforations having small spacing in the second woven area 45 are mainly used to maintain the structural strength of the woven strap 4. Through the above arrangement, the woven strap 4 can not only ensure good ventilation effect and adaptability to human feet, but also ensure the structural strength of the woven strap 4.

[0078] Furthermore, in some embodiments, as shown in FIG. 38, the woven strap 4 may be extended to serve as a portion of the front upper (which may serve as the upper in some embodiments), to create a more unique visual effect. The woven strap 4 may be connected to the upper by bonding or sewing.

[0079] In particular, the structure in which the woven strap and the pin buckle cooperate is applied to the footwear, so that the shoe disclosed in the present disclosed can be adjusted even for a foot with a deviation of 1-2 sizes. It adapts to different foot shapes and brings the users a more comfortable experience, which is an effect that is difficult to achieve with other products or designs. Secondly, the structure of the woven strap is more ventilated than the existing uppers, which helps to offer the customers a cooler experience. In addition, the existing connecting straps are mostly made of leather or polyurethane, and the holes on such connecting straps may become larger after multiple insertions. The woven strap disclosed in the present disclosure is woven from braided strips or braided wires which have certain toughness and elasticity, so that the woven perforations can remain in their original shape after being inserted with a pin many times, ensuring that the shoe still maintains its original beauty after long-term use. The braided wires may be made from polyethylene terephthalate (PET). The braided wires may be obtained by recycling plastic bottles, and then crushing, washing, melting and spinning the recycled plastic bottles. The above method is also used to produce the braided strips, which reduces landfill and pollution and can reduce the impact on the environment. In addition, the production process of recycled polyester fiber (that is, the polyethylene terephthalate obtained from recycled materials) can also reduce energy consumption and carbon emissions.

[0080] Obviously, the above embodiments of the present disclosure are merely examples for clearly illustrating the present disclosure, and are not intended to limit the implementations of the present disclosure. For those of ordinary skills in the art, other different variations or modifications can be made based on the above description. It is not necessary and impossible to list all implementations exhaustively here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this disclosure should all fall into in the protection scope of the claims of the disclosure.
