Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a pair of elastically opened and closed shoes that are easy to put on and take off. Background Art

[0002] As children grow and develop, their foot shape, foot structure and shoe-wearing and shoe-taking habits are significantly different from those of adults. Children's foot shapes vary, with different instep heights, arch shapes and calcaneal development levels, and they are constantly changing. Therefore, shoes designed for children need to pay special attention to the convenience and comfort of putting on and taking off to reduce children's adaptation to shoes. At present, the solutions for putting on and taking off shoes on the market are relatively mature, such as Velcro, adjustable elastic straps, shoelaces, turn buckles and one-step shoes. However, when these solutions are applied to children's shoes, there are many problems. For example, although Velcro is convenient, its length may not be enough for children with fat feet, resulting in the exposure of the burr surface, and it is easy to get dusty after long-term use, which reduces the stickiness. The one-step design may also be too tight or too loose for children with fat feet or high insteps. Adjustable elastic straps may lose their elasticity after long-term use. Although the turn-lock system is suitable for older children, it may not be able to be used independently by infants and children due to the difficulty in operation. In order to solve these problems, various movable elements are used in the existing easy-on and easy-off solution technologies or products on the market. These movable elements are attached to the sole part or other parts of the shoe and allow a part of the shoe to move under pressure so that the user's foot can quickly enter the shoe. However, these existing easy-on and easy-off solutions are mainly designed for adult shoes. Children of different ages have significant differences in the way they put on and take off shoes compared to adults. Therefore, easy-on and easy-off solutions for children's shoes need to be more in line with the actual needs of children. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background technology and provide an elastic opening and closing easy-to-put-on and take-off shoe, which is easy to open and has excellent recovery performance, thereby ensuring the convenience and comfort of the shoe during the putting-on and taking-off process.

[0004] To achieve the above objectives, each embodiment of the present invention adopts the following technical solutions but is not limited to the following solutions:

[0005] The first technical scheme relates to an elastic opening and closing easy-to-put-on-and-off shoe, comprising a shoe body; the shoe body comprises a sole, an upper and an elastic member; the upper comprises a forefoot portion, a heel portion and a connecting portion, all of which are connected to the sole, the connecting portion is close to the sole and connects the forefoot portion and the lower end portion of the heel portion close to the sole, and the forefoot portion and the upper end portion of the heel portion away from the sole are separated from each other; the heel portion is suitable for switching between a first state and a second state under the action of an external force, when the heel portion is in the first state, it is close to the forefoot portion and cooperates with the forefoot portion to form a complete shoe opening, when the heel portion is in the second state, it is away from the forefoot portion and opens the shoe opening; the elastic member connects the forefoot portion, the heel portion and the connecting portion, the elastic member is suitable for unfolding under the action of an external force so that the heel portion enters the second state, and once the external force is lost, the elastic member rebounds and resets to return the heel portion to the first state.

[0006] The second technical solution is based on the first technical solution, wherein the elastic member includes a first elastic portion, a second elastic portion and an elastic bottom, the first elastic portion is connected to the heel portion, the second elastic portion is connected to the forefoot portion, and the elastic bottom is connected to the connecting portion; the first elastic portion is suitable for expanding under the action of an external force away from the forefoot portion, and the first elastic portion is away from the second elastic portion with the elastic bottom as a fulcrum so that the heel portion is in a second state; the first elastic portion rebounds and recovers when the external force away from the forefoot portion is lost, and the first elastic portion approaches the second elastic portion so that the heel portion returns to the first state.

[0007] The third technical solution is based on the second technical solution, wherein the elastic member is a U-shaped structure, the first elastic part and the second elastic part are the two sides of the U-shaped structure, and the elastic bottom is the bottom of the U-shaped structure; when there is no external force on the elastic member, the opening of the U-shaped structure is closed, and the first elastic part is close to the second elastic part; when an external force is applied to the elastic member, the opening of the U-shaped structure is expanded, and the first elastic part is away from the second elastic part.

[0008] The fourth technical solution is based on the third technical solution, wherein the elastic member is arranged at the forefoot, heel and connecting portion in an inclined manner, and the opening direction of the U-shaped structure forms an angle with the extension direction of the sole and extends obliquely upward.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the length of the first elastic part is greater than the length of the second elastic part.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the number of the elastic members is two, and the two elastic members are respectively arranged on both sides of the shoe upper.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the elastic member is made of a highly elastic material.

[0012] The eighth technical solution is based on the first technical solution, wherein the elastic member is connected to the forefoot portion, the heel portion and the connecting portion by sewing, bonding or clamping and fixedly installed on the upper.

[0013] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:

[0014] In the first technical solution and related embodiments, the elastic opening and closing easy-to-wear-on and -off shoe design realizes the easy-to-wear-on and -off function of the shoe through the elastic member, while ensuring the comfort and stability of the shoe. The elastic member is connected between the forefoot and the heel of the shoe, realizing a two-part separation design. This design gives the forefoot and the heel elastic characteristics. When the wearer is ready to put on the shoe, the elastic member can be easily unfolded, so that the shoe opening is enlarged, making it easier for the wearer to put his foot into the shoe. Once the wearer's foot is inserted into the shoe, the elastic member will quickly return to the original position. Its elasticity and resilience help the shoe to fit the wearer's foot curve closely, provide necessary support, and reduce the shaking of the foot when walking or running and jumping, thereby ensuring the stability of the shoe in various actions. When the wearer is ready to take off the shoe, the elastic member is unfolded again to facilitate the foot to be taken out of the shoe. Subsequently, the elastic member will automatically return to the tightened state, shrinking the shoe opening and returning to its original position. The entire elastic opening and closing process of the shoe opening simplifies the process of putting on and taking off the shoe. This design enables the shoe to adapt to the changes in the wearer's foot shape during the wearing and taking off process, avoiding the squeezing or discomfort that may occur in traditional shoes. This design is simple and efficient, avoiding the use of complex movable elements, making the shoes both practical and fashionable. The use of elastic parts also helps to cushion the impact on the feet when walking or exercising, reducing fatigue and discomfort. Although the upper ends of the forefoot and heel are separated, the connecting part near the sole connects the lower ends of the forefoot and heel, and their connection with the elastic parts ensures the stability and support of the shoes when worn. At the same time, this separation design also brings unique lines and layers to the shoes, combined with the decorative design of the elastic parts, it can create a shoe that is both comfortable and fashionable.

[0015] In the second technical solution and related embodiments, the elastic member includes a first elastic portion, a second elastic portion and an elastic bottom. This structure allows the heel of the shoe to be easily opened when an external force is applied, thereby forming a shoe opening with a larger opening, greatly improving the convenience of wearing and taking off. The elastic member's rebound recovery performance allows the shoe to automatically return to its original state after the external force is lost, that is, the heel and forefoot cooperate to form a complete shoe opening. This feature not only ensures the structural stability of the shoe, but also ensures the comfort and safety of the shoe when worn. By using the elastic bottom as a fulcrum, the first elastic portion can be away from the second elastic portion when an external force is applied, thereby opening the heel and making the opening and closing action of the shoe smoother.

[0016] In the third technical solution and related embodiments, the design of the U-shaped structure enables the elastic member to have excellent structural stability. This structure can effectively disperse external forces, such as the force generated by the wearer when putting on and taking off shoes or walking, thereby ensuring that the elastic member can maintain its shape and function for a long time. The U-shaped structure usually has good elastic properties. This allows the elastic member to be easily unfolded when subjected to external force, making it convenient for the wearer to put on and take off shoes; and after the external force disappears, the elastic member can quickly return to its original state to maintain the stability of the shoe. Due to the characteristics of the U-shaped structure, the elastic member can adapt to changes in different foot shapes and foot structures. Whether it is a wearer with fat feet or a high instep, this structure can adapt to a certain extent and provide a comfortable wearing experience. At the same time, the U-shaped structure is relatively simple and easy to manufacture and process.

[0017] In the fourth technical solution and related embodiments, due to the upward tilt design of the opening of the elastic member, when the wearer tries to put on the shoes, the foot can more easily enter the shoe along this tilt direction. Similarly, when taking off the shoes, the foot can also be easily moved out along this direction. The tilted design helps to reduce the friction between the foot and the upper, especially in the process of putting on and taking off the shoes, which can further increase the convenience of putting on and taking off. Due to the tilted design, the pressure points of the elastic member on the upper are more evenly distributed, which helps to reduce the discomfort or pressure that the wearer may feel when putting on and taking off the shoes. This tilted design takes into account ergonomics and the anatomical structure of the foot, so that the shoes can fit the curve of the foot when worn, providing excellent comfort and support. At the same time, this tilted design not only takes into account practicality, but also takes into account aesthetics. The tilted design of the streamlined U-shaped structure makes the shoe look more fashionable and beautiful as a whole, meeting the aesthetic needs of modern people.

[0018] In the fifth technical solution and related embodiments, since the first elastic part is connected to the heel portion and has a long length, it can provide a stronger support force when the wearer wears the shoes, ensuring the stability of the shoes, especially in the heel portion. Although the first elastic part is long, since it is designed near the heel portion, when the wearer tries to wear the shoes, the foot can enter the shoe more easily. At the same time, when it is necessary to take off the shoes, since the length of the first elastic part is large, it can provide more elastic deformation stretching space to a certain extent, making the shoe-taking process smoother. By adjusting the length difference between the first elastic part and the second elastic part, this design can better adapt to wearers with different foot types. For example, for wearers with higher insteps, the longer first elastic part can provide better adaptability and comfort. Since the first elastic part is close to the heel portion of the shoe and has a long length, it is more evenly distributed in the shoe, which helps to reduce the pressure or discomfort that the wearer may feel when wearing shoes.

[0019] In the sixth technical solution and related embodiments, the elastic opening and closing easy-to-put-on-and-off shoes realize the support and adjustment functions on both sides of the shoes by arranging an elastic member on each side of the upper. The two elastic members are respectively located on the left and right sides of the upper, providing bilateral support for the shoes. This design ensures that the shoes can firmly fit the wearer's foot shape when worn, especially on both sides of the foot, providing additional support and stability. By arranging elastic members on both sides, the pressure on the side of the shoe can be more evenly distributed. This helps to reduce the discomfort caused by excessive local pressure and improve the comfort of the shoes. There are differences in the foot shapes of different wearers, especially in the width of the feet. The design of the bilateral elastic members can adapt to the foot shapes of different widths and provide a more personalized wearing experience. When the wearer walks or performs other activities, the bilateral elastic members can work together to effectively resist external impact and twisting force, maintain the stability of the shoes, and protect the safety of the wearer's feet.

[0020] In the seventh technical solution and related embodiments, the elastic member made of high elastic material has excellent elasticity and resilience. This means that the elastic member can easily stretch when subjected to external force, and then quickly return to its original state, ensuring that the shoe always fits the wearer's foot closely. High elastic materials generally have excellent durability and fatigue resistance. Even if the elastic member is used for a long time or is frequently subjected to external force, it can maintain its original elasticity and function, thereby extending the service life of the shoe.

[0021] In the eighth technical solution and related embodiments, the elastic opening and closing easy-to-put-on-and-take-off shoes connect the elastic member to the shoe upper by sewing, gluing or snapping, and are not easy to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figures 1 to 3 ,like Figure 1 and Figure 2 As shown, an elastic opening and closing easy-to-put-on-and-take-off shoe comprises a shoe body 1.

[0034] The shoe body 1 comprises a sole 2, an upper 3 and an elastic member 4.

[0035] The sole 2 is a conventional structure that is in direct contact with the ground. Its structure generally includes an outer sole, a midsole, and a heel. The outer sole mainly plays the role of anti-skid, wear-resistant and foot protection, and needs to have good physical and chemical properties. The midsole mainly plays the role of buffering and supporting, reducing the impact on the foot. The heel provides additional support and stability, especially when walking or running.

[0036] The upper 3 is the outer part of the shoe, and its main function is to wrap the foot, and is located above the sole 2. It is usually made of a variety of fabrics, such as cloth, synthetic materials, etc. The upper 3 is connected to the sole 2 through a certain process and structure to ensure the stability and comfort of the shoe.

[0037] The upper 3 includes a forefoot portion 5, a heel portion 6 and a connecting portion 7, all of which are connected to the sole 2. The connecting portion 7 is close to the sole 2 and connects the forefoot portion 5 and the heel portion 6 close to the lower end of the sole 2. The forefoot portion 5 and the heel portion 6 are separated from each other away from the upper end of the sole 2.

[0038] Specifically, the forefoot portion 5 includes the rest of the entire upper 3 except the heel portion 6 and the connecting portion 7, and its range corresponds to the position from the toes to the instep of the foot. The lower edge of the forefoot portion 5 is compounded on the sole 2. The heel portion 6 corresponds to the heel of the foot, and it can cover the positions on both sides of the heel of the foot; the lower edge of the heel portion 6 is also compounded on the sole 2. The connecting portion 7 is close to the sole 2 and connected to the lower ends of the forefoot portion 5 and the heel portion 6. The forefoot portion 5 and the heel portion 6 are connected by the connecting portion 7 near the lower end of the sole 2 and are separated from each other away from the upper end of the sole 2, so as to ensure that the heel portion 6 will not completely separate from the forefoot portion 5 and still have a supporting effect on the foot.

[0039] The heel portion 6 is adapted to switch between the first state and the second state under the action of an external force. Figure 1 As shown, when the heel portion 6 is in the first state, it is close to the forefoot portion 5 and cooperates with the forefoot portion 5 to form a complete shoe opening 11, as shown in FIG. Figure 2 As shown, when the heel portion 6 is in the second state, it is away from the forefoot portion 5 and the shoe opening 11 is opened. Specifically, in the normal state, the heel portion 6 cooperates with the forefoot portion 5 to form the shoe opening 11. Based on the characteristics of the material of the upper 3, it has good deformation characteristics. When the upper end of the heel portion 6 is subjected to an external force away from the forefoot portion 5, it folds backward and deforms, and the shoe opening 11 opens, making it easier for the wearer's foot to enter the inner cavity of the shoe. It should be noted that when the heel portion 6 switches from the first state to the second state, the lower end of the heel portion 6 and the connecting portion 7 do not change, and the deformation of the upper end of the heel portion 6 is achieved based on its own material characteristics.

[0040] Elastic member 4, such as Figures 1 to 3 As shown, the elastic member 4 includes a first elastic portion 8, a second elastic portion 9 and an elastic bottom 10. The first elastic portion 8 is connected to the heel portion 6, the second elastic portion 9 is connected to the forefoot portion 5, and the elastic bottom 10 is connected to the connecting portion 7. Specifically, the connection between the elastic member 4 and the forefoot portion 5, the heel portion 6 and the connecting portion 7 is fixedly installed on the upper 3 by sewing, bonding or clamping, and is not easy to fall off. In this embodiment, the elastic member 4 is a U-shaped structure, the first elastic portion 8 and the second elastic portion 9 are the two sides of the U-shaped structure, and the elastic bottom 10 is the bottom of the U-shaped structure. When there is no external force on the elastic member 4, the opening of the U-shaped structure is closed, and the first elastic portion 8 is close to the second elastic portion 9; when the elastic member 4 is under the action of an external force, the opening of the U-shaped structure is opened, and the first elastic portion 8 is away from the second elastic portion 9. In this embodiment, the elastic member 4 is arranged at the forefoot portion 5, the heel portion 6 and the connecting portion 7 in an inclined manner, and the opening direction of the U-shaped structure forms an angle with the extension direction of the sole 2 and extends obliquely upward. The length of the first elastic portion 8 is greater than the length of the second elastic portion 9. The length of the second elastic part 9 is about half of the length of the first elastic part 8. After the longer first elastic part 8 is elastically deformed, the stretching distance is relatively large, which can make the opening of the shoe opening 11 larger, making it easier for the wearer's foot to enter the inner cavity of the shoe. Since the second elastic part 9 is connected to the forefoot part 5, the elastic deformation distance is relatively small, and the forefoot part 5 has almost no change during the process of increasing the opening of the shoe opening 11. At the same time, the end of the second elastic part 9 is in an arc shape and bends toward the first elastic part 8, so that the first elastic part 8 does not need to rebound to the state where the first elastic part 8 and the second elastic part 9 are completely closed. When the end of the second elastic part 9 is attached to the first elastic part 8, the part of the second elastic part 9 close to the elastic bottom 10 is still separated from the first elastic part 8, which can reduce the rebound distance of the first elastic part 8.

[0041] There are two elastic members 4, and the two elastic members 4 are respectively arranged on both sides of the upper. The elastic member 4 is made of a highly elastic material. The selection of highly elastic materials needs to have excellent elasticity and resilience. This means that the elastic member 4 can easily stretch when subjected to external force, and then quickly return to its original state, ensuring that the shoe always fits the wearer's foot shape closely. Highly elastic materials usually have excellent durability and fatigue resistance. Even after long-term use or frequent external force, the elastic member 4 can maintain its original elasticity and function, thereby extending the service life of the shoe. Specifically, the highly elastic material can be selected from materials with good elastic properties such as polyurethane (PU), natural rubber or thermoplastic elastomer (TPE).

[0042] The elastic member 4 connects the forefoot portion 5, the heel portion 6 and the connecting portion 7. The elastic member 4 is adapted to be expanded under the action of an external force so that the heel portion 6 enters the second state. Once the external force is lost, the elastic member 4 rebounds and resets to return the heel portion 6 to the first state. Specifically, the first elastic portion 8 is adapted to be expanded under the action of an external force away from the forefoot portion 5. The first elastic portion 8 is away from the second elastic portion 9 with the elastic bottom 10 as a fulcrum so that the heel portion 6 is in the second state. When the external force away from the forefoot portion 5 is lost, the first elastic portion 8 rebounds and recovers, and the first elastic portion 8 approaches the second elastic portion 9 to return the heel portion 6 to the first state. Figure 3 As shown, an external force away from the second elastic part 9 is applied to the top position of the first elastic member 4, the first elastic part 8 elastically deforms away from the second elastic part 9, the opening of the U-shaped structure of the elastic member 4 opens, and the heel portion 6 is folded away from the forefoot portion 5 at this time, and the heel portion 6 switches to the second state, and the wearer's foot can easily enter the inner cavity of the shoe from the opened shoe mouth 11; when the shoe is put on, the first elastic part 8 elastically recovers and wraps the wearer's foot, giving the wearer enough support to walk; when the shoe needs to be taken off, the wearer's foot applies a force away from the forefoot portion 5 to the first elastic part 8, the first elastic part 8 elastically deforms, the opening of the U-shaped structure of the elastic member 4 opens, and the wearer's foot can easily detach from the shoe from the inner cavity of the shoe; at this time, the first elastic part 8 elastically recovers and approaches the second elastic part 9, the heel portion 6 approaches the forefoot portion 5, and the heel portion 6 returns to the first state.

[0043] In this embodiment, the elastic member 4 includes a first elastic portion 8, a second elastic portion 9 and an elastic bottom 10. This structure allows the shoe to easily open the heel portion 6 when subjected to an external force, thereby forming a shoe opening 11 with a larger opening, greatly improving the convenience of wearing and taking off. The elastic member 4 has a rebound recovery performance that allows the shoe to automatically return to its original state after the external force is lost, that is, the heel portion 6 cooperates with the forefoot portion 5 to form a complete shoe opening 11. This feature not only ensures the structural stability of the shoe, but also ensures the comfort and safety of the shoe when worn. By using the elastic bottom 10 as a fulcrum, the first elastic portion 8 can be away from the second elastic portion 9 when subjected to an external force, thereby opening the heel portion 6 and making the opening and closing action of the shoe smoother.

[0044] In this embodiment, the design of the U-shaped structure enables the elastic member 4 to have excellent structural stability. This structure can effectively disperse external forces, such as the force generated by the wearer when putting on and taking off shoes or walking, thereby ensuring that the elastic member 4 can maintain its shape and function for a long time. The U-shaped structure usually has good elastic properties. This allows the elastic member 4 to be easily unfolded when subjected to external forces, making it convenient for the wearer to put on and take off shoes; and after the external force disappears, the elastic member 4 can quickly return to its original state to maintain the stability of the shoes. Due to the characteristics of the U-shaped structure, the elastic member 4 can adapt to changes in different foot shapes and foot structures. Whether it is a wearer with fat feet or a high instep, this structure can adapt to a certain extent and provide a comfortable wearing experience. At the same time, the U-shaped structure is relatively simple and easy to manufacture and process.

[0045] In this embodiment, due to the upward tilt design of the opening of the elastic member 4, when the wearer tries to put on the shoes, the foot can more easily enter the shoes along this tilt direction. Similarly, when taking off the shoes, the foot can also be easily moved out along this direction. The tilted design helps to reduce the friction between the foot and the upper, especially in the process of putting on and taking off the shoes, which can further increase the convenience of putting on and taking off. Due to the tilted design, the pressure points of the elastic member 4 on the upper are more evenly distributed, which helps to reduce the discomfort or pressure that the wearer may feel when putting on and taking off the shoes. This tilted design takes into account ergonomics and the anatomical structure of the foot, so that the shoes can fit the curve of the foot when worn, providing excellent comfort and support. At the same time, this tilted design not only takes practicality into consideration, but also takes into account aesthetics. The tilted design of the streamlined U-shaped structure makes the shoes look more fashionable and beautiful as a whole, meeting the aesthetic needs of modern people.

[0046] In the present embodiment, because the first elastic part 8 connects the heel part 6 and the length is long, it can provide stronger support when the wearer wears shoes, ensure the stability of the shoes, particularly at the heel part 6. Although the first elastic part 8 is long, because it is designed near the heel part 6, when the wearer tries to wear shoes, the foot can enter the shoe more easily. Meanwhile, when it is necessary to take off the shoes, because the length of the first elastic part 8 is large, it can provide more elastic deformation stretching space to a certain extent, making the shoe-taking process smoother. By adjusting the length difference of the first elastic part 8 and the second elastic part 9, this design can better adapt to the wearer of different foot types. For example, for the wearer with a higher instep, the longer first elastic part 8 can provide better adaptability and comfort. Because the first elastic part 8 is close to the heel part 6, and the length is long, its distribution in the shoe is more uniform, which helps to reduce the pressure or discomfort that the wearer may feel when wearing shoes.

[0047] In this embodiment, the elastic opening and closing easy-to-put-on and -off shoes realize the support and adjustment functions on both sides of the shoes by arranging an elastic member 4 on both sides of the upper. The two elastic members 4 are respectively located on the left and right sides of the upper, providing the shoes with bilateral support. This design ensures that the shoes can firmly fit the wearer's foot shape when worn, especially on both sides of the foot, providing additional support and stability. By arranging the elastic members 4 on both sides, the pressure on the side of the shoe can be more evenly distributed. This helps to reduce the discomfort caused by excessive local pressure and improve the comfort of the shoes. There are differences in the foot shapes of different wearers, especially in the width of the foot. The design of the bilateral elastic members 4 can adapt to the foot shapes of different widths and provide a more personalized wearing experience. When the wearer walks or performs other activities, the bilateral elastic members 4 can work together to effectively resist external impact and twisting force, maintain the stability of the shoes, and protect the safety of the wearer's feet.

[0048] In this embodiment, the elastic opening and closing easy-to-put-on and -off shoes design realizes the easy-to-put-on and -off function of the shoes through the elastic member 4, while ensuring the comfort and stability of the shoes. The elastic member 4 is connected between the forefoot 5 and the heel 6 of the shoe, realizing the separation design of the two parts. This design gives the elastic characteristics between the forefoot 5 and the heel 6. When the wearer is ready to put on the shoes, the elastic member 4 can be easily unfolded, so that the shoe opening 11 is enlarged, which is convenient for the wearer to put the foot into the shoe. Once the wearer's foot is inserted into the shoe, the elastic member 4 will quickly return to the original position. Its elasticity and resilience help the shoes to fit the wearer's foot curve closely, provide necessary support, reduce the shaking of the foot when walking or running and jumping, thereby ensuring the stability of the shoes in various actions. When the wearer is ready to take off the shoes, the elastic member 4 is unfolded again, which is convenient for the foot to be taken out of the shoes. Subsequently, the elastic member 4 will automatically return to the tightened state, so that the shoe opening 11 is reduced and returned to its original position. The entire elastic opening and closing process of the shoe opening 11 simplifies the process of putting on and taking off the shoes. This design allows the shoe to adapt to the wearer's foot shape during the wearing and taking off process, avoiding the squeezing or discomfort that may occur in traditional shoes. This design is simple and efficient, avoiding the use of complex movable elements, making the shoe both practical and fashionable. The use of the elastic member 4 also helps to cushion the impact on the foot during walking or exercise, reducing fatigue and discomfort. Although the upper ends of the forefoot 5 and the heel 6 are separated, the connecting portion 7 near the sole 2 connects the lower ends of the forefoot 5 and the heel 6, and their connection with the elastic member 4 ensures the stability and support of the shoe when worn. At the same time, this separation design also brings unique lines and layering to the shoes. Combined with the decorative design of the elastic member 4, a comfortable and fashionable shoe can be created.
