[0035] Shoes are an indispensable daily necessity in people's lives. With the continuous improvement of living standards, people's demands for shoe comfort are becoming increasingly higher. Due to the varying shapes of human heels, the fit between the heel and the shoe heel varies from person to person. Some people experience foot rubbing from wearing shoes, while others experience foot slippage from the shoes. To address this issue, embodiments of the present application provide a shoe heel cover 100 (shown in FIG. 1 ) and a shoe 1000 (shown in FIG. 8 ).

[0036] Referring to Figures 1 to 3, the shoe rear cover 100 of the embodiment of the present application includes a wrapping member 10 and a support member 30. The support member 30 includes a first side 31 and a second side 33 opposite to each other. The wrapping member 10 protrudes from the first side 31 of the support member 30 toward the second side 33 away from the support member 30. The wrapping member 10 includes at least two protrusions 11, and the at least two protrusions 11 are arranged in sequence in the height direction X of the shoe rear cover 100.

[0037] Specifically, referring to Figure 8 , the heel cover 100 is connected to the upper 300 and installed at the heel of the shoe 1000. The heel cover 100 is used to increase the rigidity of the heel and also provides support and shaping for the heel, thereby enhancing the aesthetics of the shoe 1000. The installation of the heel cover 100 enhances the overall support and stability of the shoe 1000, preventing the foot from shaking and twisting during walking. The connection between the heel cover 100 and the upper 300 is not limited to sewing or pressing, so as to ensure a secure connection between the heel cover 100 and the upper 300.

[0038] The support member 30 is used to support and shape the shoe heel 100 so that the shape is more three-dimensional, thereby improving the overall aesthetics of the shoe 1000. The support member 30 is a structure with a certain hardness. When the user wears the shoe, the support member 30 can provide good protection for the user's heel. In one embodiment, the material of the support member 30 can be thermoplastic polyurethane (TPU), EVA solid sponge (ESS), acrylonitrile-butadiene-styrene (ABS), thermosetting polyurethane (PU), or sea brittle material. In this case, the support member 30 has a high hardness and a light weight.

[0039] In other embodiments, the support member can also be formed by the upper at the heel. In this case, the upper (support member) at the heel is relatively hard, and the support member can provide better support for the heel cover while also effectively shaping the shoe. When the support member is formed by the upper at the heel, the heel cover is connected to the support member, thereby providing better support for the user's heel.

[0040] Referring to Figures 1 to 3 , when a user is wearing shoes, the first side 31 of the support member 30 is closer to the user's heel than the second side 33 of the support member 30. The heel is divided into an upper portion and a lower portion in terms of height. Friction between the upper portion of the heel and the top of the shoe's heel can easily cause foot rubbing. Heels typically have a curvature, and if the curvature of the lower portion is smaller, the heel can easily separate from the shoe's heel, causing the foot to fall off. The wrapping member 10 is a structure that supports and wraps the upper and lower portions of the heel. When the user is wearing shoes, the wrapping member 10 fits against the upper portion of the heel, preventing friction between the upper portion and the shoe's heel, which can cause foot rubbing. The wrapping member 10 also fits against the lower portion of the heel, preventing the lower portion of the heel from separating from the shoe, which can cause the foot to fall off. The material of the wrapping member 10 can be, but is not limited to, foam, latex, or PU. The wrapping member 10 is a soft and elastic structure. Since the wrapping piece 10 has a certain elasticity, when the user wears shoes, the wrapping piece 10 is squeezed and tends to rebound (i.e., restore its original shape), so that the wrapping piece 10 can fit tightly against the heel to protect the user's heel and avoid problems such as foot friction and foot falling.

[0041] Protrusion 11 is a soft and elastic structure used to support the user's heel. In the height direction X of the shoe cover 100, the taller protrusion 11 is designed to fit against the upper part of the heel to prevent direct contact and friction between the upper part of the heel and the shoe back, which could cause foot rubbing. The shorter protrusion 11 supports the lower part of the heel, ensuring a more stable fit and preventing the foot from falling off.

[0042] The number of protrusions 11 can be, but is not limited to, two, three, four, or more. When there are two protrusions 11, in the height direction X of the shoe back cover 100, the higher protrusion 11 is used to fit the upper part of the heel, and the lower protrusion 11 is used to support the lower part of the heel. When there are three protrusions 11, in one example, the two higher protrusions 11 are used to fit the upper part of the heel, and the lower protrusion 11 is used to support the lower part of the heel. In another example, the higher protrusion 11 is used to fit the upper part of the heel, and the lower two protrusions 11 are used to support the lower part of the heel. When there are four protrusions 11, the two higher protrusions 11 are used to fit the upper part of the heel, and the lower two protrusions 11 are used to support the lower part of the heel.

[0043] In the shoe rear cover 100 of the embodiment of the present application, the wrapping member 10 protrudes from the first side 31 of the support member 30 toward the second side 33 away from the support member 30, and includes at least two protrusions 11. In the height direction X of the shoe rear cover 100, the protrusions 11 of the higher part fit the upper part of the heel, preventing the upper part of the heel from rubbing against the heel of the shoe, thereby preventing the problem of foot rubbing. The protrusions 11 of the lower part are used to support the lower part of the user's heel, thereby preventing the problem of foot falling off. The shoe rear cover 100 of the present application can solve the problems of foot rubbing and foot falling off at the same time by providing at least two protrusions 11.

[0044] The shoe rear cover 100 will be further described below with reference to the accompanying drawings.

[0045] Referring to Figures 1 and 2 , in certain embodiments, the shoe cover 100 further includes a mesh 50 that wraps around the support member 30 and the wrapping member 10. The mesh 50 is used to wrap around the support member 30 and the wrapping member 10, thereby forming a complete shoe cover 100 and enhancing the overall aesthetics of the shoe cover 100. The shoe cover 100 includes a first side 101 and a second side 103, opposite each other. The first side 101 of the shoe cover 100 is closer to the user's heel than the second side 103. The protrusion 11 is located on the first side 101 of the shoe cover 100. The mesh 50 located on the first side 101 of the shoe cover 100 is designed to directly contact the heel. The mesh 50 can be made of genuine leather or synthetic materials, including, but not limited to, polyester, nylon, or artificial leather. Genuine leather provides greater comfort, breathability, and wear resistance. When the mesh 50 is made of a synthetic material, it is relatively lightweight and inexpensive. In one embodiment, during assembly of the shoe rear cover 100, the wrapping member 10 is first placed on the first side 31 of the support member 30, and then the mesh 50 fully wraps the support member 30 and the wrapping member 10. In another embodiment, during assembly of the shoe rear cover 100, the wrapping member 10 is first placed on the first side 31 of the support member 30, and then the mesh 50 wraps the wrapping member 10 from both the first side 31 of the support member 30 and the first side 31 of the support member 30. The method by which the mesh 50 wraps the support member 30 and the wrapping member 10 is not limited to lamination or sewing.

[0046] Please refer to Figures 1 and 3. In some embodiments, the wrapping member 10 includes a first protrusion 13 and a second protrusion 15. In the height direction X of the shoe rear cover 100, the first protrusion 13 and the second protrusion 15 are arranged in sequence, and the position of the first protrusion 13 is higher than that of the second protrusion 15.

[0047] Specifically, in the height direction X of the shoe rear cover 100, the first protrusion 13 is located near the top of the shoe rear cover 100. When the user wears shoes, the first protrusion 13 corresponds to the top of the heel. The first protrusion 13 is designed to fit the top of the heel, preventing friction between the top of the heel and the top of the shoe heel, which could cause foot rubbing. Furthermore, because the first protrusion 13 is soft and elastic, the user's wearing experience is more comfortable. The number of first protrusions 13 can be, but is not limited to, one, two, three, or more. If there is only one first protrusion 13, the processing of the shoe rear cover 100 is more convenient. If there are multiple first protrusions 13, the multiple first protrusions 13 are arranged in sequence in the height direction of the shoe rear cover 100, and the multiple first protrusions 13 may or may not be spaced apart.

[0048] Compared to the first protrusion 13, the second protrusion 15 is further away from the top of the shoe cover 100. When the user is wearing shoes, the second protrusion 15 corresponds to the lower part of the user's heel. The second protrusion 15 is used to support and hold the lower part of the heel, making the user's shoes more stable and preventing the shoes from falling. Furthermore, because the second protrusion 15 is soft and elastic, the user's shoes are more comfortable to wear. The number of second protrusions 15 can be, but is not limited to, one, two, three, or more. If there is only one second protrusion 15, the processing of the shoe cover 100 is more convenient. If there are multiple second protrusions 15, the multiple second protrusions 15 are arranged in sequence in the height direction X of the shoe cover 100, and the multiple second protrusions 15 may or may not be spaced apart. The number of first protrusions 13 and the number of second protrusions 15 can be the same or different.

[0049] Referring to FIG. 3 , in some embodiments, in the height direction X of the rear shoe cover 100 , the height Z1 of the wrapping member 10 is 1 / 2 of the height Z2 of the rear shoe cover 100 .

[0050] In the height direction X of the shoe rear cover 100, the wrapping member 10 is close to the top of the shoe rear cover 100. When the height Z1 of the wrapping member 10 is less than 1 / 2 of the height Z2 of the shoe rear cover 100, the wrapping member 10 cannot correspond to the position of the lower part of the heel, so the support effect of the wrapping member 10 on the lower part of the heel is poor, and the user is likely to fall off the shoe when wearing the shoe. When the height Z1 of the wrapping member 10 is greater than 1 / 2 of the height Z2 of the shoe rear cover 100, the wrapping member 10 will extend downward to the position below the lower part of the heel, and the user will feel that the position below the lower part of the heel is too crowded when wearing the shoe, and the user will feel less comfortable wearing the shoe. When the height Z1 of the wrapping member 10 is 1 / 2 of the height Z2 of the shoe rear cover 100, when the user wears the shoe, the wrapping member 10 can correspond to the upper and lower parts of the heel at the same time, thereby better avoiding the problem of rubbing the foot and falling off the shoe when wearing the shoe.

[0051] In the height direction X of the heel cover 100, the height Z1 of the wrapping member 10 is the sum of the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15. When the wrapping member 10 is close to the top of the heel cover 100 and the height Z1 of the wrapping member 10 is half the height Z2 of the heel cover 100, the first protrusion 13 can correspond to the position of the ankle, and the second protrusion 15 can correspond to the position of the heel, thereby effectively preventing the upper part of the heel from rubbing and the lower part of the heel from falling off.

[0052] In the height direction X of the shoe back cover 100, the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 can be the same. The height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 can also be different. In one example, the height Z11 of the first protrusion 13 is greater than the height Z12 of the second protrusion 15. In this case, the contact area between the first protrusion 13 and the upper part of the heel is larger, and the first protrusion 13 can better protect the upper part of the user's heel from being rubbed by the heel of the shoe. In another example, the height Z12 of the second protrusion 15 is greater than the height Z11 of the first protrusion 13. In this case, the contact area between the second protrusion 15 and the heel is larger, and the second protrusion 15 provides better support for the lower part of the user's heel. In the present application, the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 are the same.

[0053] Referring to Figure 3 , in some embodiments, a groove 17 is provided between the first protrusion 13 and the second protrusion 15. In this case, when the user is wearing shoes, the contact area between the wrapping member 10 and the heel is relatively small. The groove 17 allows for ventilation between the wrapping member 10 and the heel, preventing the heel from being completely in contact with the wrapping member 10, which could cause stuffiness and provide a more comfortable fit.

[0054] In other embodiments, when there are multiple first protrusions 13, grooves 17 may be provided between the multiple first protrusions 13. When there are multiple second protrusions 15, grooves 17 may also be provided between the multiple second protrusions 15. In this case, the area of ​​contact between the wrapping member 10 and the heel is smaller, and the multiple grooves 17 allow for greater ventilation between the wrapping member 10 and the heel, making the wearer more comfortable.

[0055] 2 and 3 , in some embodiments, a maximum height H2 of the second protrusion 15 protruding from the first side 31 of the support member 30 is greater than a maximum height H1 of the first protrusion 13 protruding from the first side 31 of the support member 30 .

[0056] Specifically, as can be seen from the cross-sectional view shown in FIG2 , the first protrusion 13 is an arc-shaped protrusion protruding from the first side 31 of the support member 30. The maximum height H1 of the first protrusion 13 protruding from the first side 31 of the support member 30 refers to the distance between the most protruding point of the surface of the first protrusion 13 relative to the first side 31 of the support member 30 and the first side 31 of the support member 30. When the first protrusion 13 is an arc-shaped protrusion protruding from the first side 31 of the support member 30, the first protrusion 13 can better fit the shape of the foot, making the user more comfortable to wear. The second protrusion 15 is also an arc-shaped protrusion protruding from the first side 31 of the support member 30. The maximum height H2 of the second protrusion 15 protruding from the first side 31 of the support member 30 refers to the distance between the most protruding point of the surface of the second protrusion 15 relative to the first side 31 of the support member 30 and the first side 31 of the support member 30. In the case where the second protrusion 15 is an arc-shaped protrusion protruding from the first side 31 of the supporting member 30, the second protrusion 15 can better fit the shape of the foot, and the user is more comfortable wearing it.

[0057] Because the heel has a curvature, when a user wears shoes, the lower portion of the heel will be further away from the heel than the upper portion of the heel. In other words, the gap between the lower portion of the heel and the heel will be larger than the gap between the upper portion of the heel and the heel. If the maximum height H2 of the second protrusion 15 protruding from the first side 31 of the support member 30 is less than the maximum height H1 of the first protrusion 13 protruding from the first side 31 of the support member 30, when the user wears shoes, after the first protrusion 13 is in contact with the upper portion of the heel, a gap will exist between the lower portion of the heel and the second protrusion 15, and the second protrusion 15 will be unable to support the lower portion of the heel. In this case, the wrapping member 10 will provide poor support for the lower portion of the user's heel. When the maximum height H2 of the second protrusion 15 protruding from the first side 31 of the support member 30 is greater than the maximum height H1 of the first protrusion 13 protruding from the first side 31 of the support member 30, when the user wears the shoe, the first protrusion 13 fits against the upper part of the heel while the second protrusion 15 can also support the lower part of the user's heel. In this case, the wrapping member 10 provides better support for the user's heel.

[0058] Referring to Figures 2, 4, and 5, in certain embodiments, the first protrusion 13 includes a first body portion 131 and a first protruding portion 133. The first protruding portion 133 is disposed at least at one free end of the first protrusion 13. A height H12 of the first protruding portion 133 protruding from the first side 31 of the support member 30 is greater than a height H11 of the first body portion 131 protruding from the first side 31 of the support member 30. The second protrusion 15 includes a second body portion 151 and a second protruding portion 153. The second protruding portion 153 is disposed at least at one free end of the second protrusion 15. A height H22 of the second protruding portion 153 protruding from the first side 31 of the support member 30 is greater than a height H21 of the second body portion 151 protruding from the first side 31 of the support member 30.

[0059] Referring to Figure 8 , after the heel cover 100 is connected to the upper 300, the heel cover 100 has a curved structure that can wrap around the foot. Thus, the first protrusion 13 has a curved structure that can wrap around the heel, and the second protrusion 15 also has a curved structure that can wrap around the ankle. The curved first and second protrusions 13, 15 support and wrap the user's heel, providing greater comfort.

[0060] Referring to Figures 2 and 4 , the first protrusion 133 is used to support the side of the upper heel, preventing the side of the upper heel from directly rubbing against the upper 300 and causing foot rubbing. When a user wears the shoes, due to the different foot shapes of each person, there may be a certain gap between the side of the upper heel and the upper 300. If the height H12 of the first protrusion 133 protruding from the first side 31 of the support member 30 is less than or equal to the height H11 of the first body 131 protruding from the first side 31 of the support member 30, there may be a gap between the side of the upper heel and the first protrusion 133, making it difficult for the first protrusion 133 to fit the side of the upper heel, and the first protrusion 133's support and wrapping of the upper heel are poor. When the height H12 of the first protrusion 133 protruding from the first side 31 of the support member 30 is greater than the height H11 of the first main body 131 protruding from the first side 31 of the support member 30, the first protrusion 133 can fill the gap between the upper side of the heel and the upper 300, so that the first protrusion 13 has better wrapping and support for the upper side of the heel, and the user can wear the shoes more stably, which can avoid the problem of falling off.

[0061] In one embodiment, the first protrusion 13 is provided with a first protrusion 133. In this case, the first protrusion 133 can be provided at any one of the two free ends of the first protrusion 13. In this case, the provision of the first protrusion 13 can save foam material. In another embodiment, the first protrusion 13 is provided with two first protrusions 133. The two first protrusions 133 are respectively provided at the two free ends of the first protrusion 13. In this case, the first protrusion 13 can prevent the upper 300 from rubbing against the side position of the upper part of the heel, and the first protrusion 13 has a better wrapping property for the upper part of the heel, and the user can wear the shoes more stably and comfortably. The first protrusion 13 of the present application includes two first protrusions 133.

[0062] 2 and 5 , the second protrusion 153 is used to support the side of the lower heel and fill the gap between the side of the lower heel and the upper 300, thereby providing a more stable fit for the user and preventing the user from falling off the shoe. If the height H12 of the second protrusion 153 protruding from the first side 31 of the support member 30 is less than or equal to the height H11 of the second body 151 protruding from the first side 31 of the support member 30, the second protrusion 153 may not fill the gap between the side of the lower heel and the upper 300 when the user wears the shoe, resulting in poor support and support for the side of the lower heel by the second protrusion 153. When the height H22 of the second protrusion 153 from the first side 31 of the support member 30 is greater than the height H21 of the second body 151 from the first side 31 of the support member 30, the second protrusion 153 can fill the gap between the side portion of the lower portion of the heel and the shoe upper 300, thereby making the shoe more secure for the user and preventing the user from falling off. In this case, the second protrusion 153 can better wrap around and support the side portion of the lower portion of the heel.

[0063] In one embodiment, the second protrusion 15 is provided with a second protrusion 153. In this case, the second protrusion 153 can be provided at any one of the two free ends of the second protrusion 15. In this case, the provision of the second protrusion 15 can save foam material. In another embodiment, the second protrusion 15 is provided with two second protrusions 153. The two second protrusions 153 are respectively provided at the two free ends of the second protrusion 15. In this case, the second protrusion 15 provides better support and wrapping for the heel, and the user can wear the shoes more stably, which can avoid the problem of falling off the feet, and the user is more comfortable wearing. The second protrusion 15 of the present application includes two second protrusions 153.

[0064] 2 and 6 , in some embodiments, the height H22 of the second protrusion 153 from the first side 31 of the support member 30 is greater than the height H12 of the first protrusion 133 from the first side 31 of the support member 30. In this case, the second protrusion 153 provides better support for the lower portion of the heel and completely fills the gap between the side of the lower portion of the heel and the shoe upper 300, ensuring a more secure fit and preventing the shoe from falling off.

[0065] Referring to FIG. 7 , in some embodiments, in the length direction Y when the shoe rear cover 100 is in the expanded state, the length L11 of the first protrusion 133 is [10%, 15%] of the length L1 of the first protrusion 13 , and the length L21 of the second protrusion 153 is [10%, 15%] of the length L2 of the second protrusion 15 .

[0066] Specifically, the length of one first protrusion 133 is [10%, 15%] of the length L1 of the first protrusion 13 , and the length L21 of one second protrusion 153 is [10%, 15%] of the length L2 of the second protrusion 15 .

[0067] If the length L11 of the first protrusion 133 is less than 10% of the length L1 of the first protrusion, the contact area between the first protrusion 133 and the lateral portion of the upper portion of the heel is small, and the first protrusion 133 cannot fill the gap between the lateral portion of the upper portion of the heel and the shoe upper 300 (shown in FIG. 7 ). Consequently, the first protrusion 133 provides poor support and wrapping for the upper portion of the heel. If the length L11 of the first protrusion 133 is greater than 15% of the length L1 of the first protrusion, the first protrusion 133 extends from the lateral portion of the upper portion of the heel to the upper portion of the heel. The first protrusion 133 extending to the upper portion of the heel will cause the upper portion of the heel to be too crowded when the shoe is worn, resulting in poor wearing comfort. When the length L11 of the first protrusion 133 is [10%, 15%] of the length L1 of the first protrusion 13, the first protrusion 133 can fill the gap between the side of the upper portion of the heel and the shoe upper 300, and the first protrusion 133 provides good support and wrapping for the upper portion of the heel. Furthermore, the first protrusion 133 does not extend from the side of the upper portion of the heel to the upper portion of the heel.

[0068] If the length L21 of the second protrusion 153 is less than 10% of the second protrusion length L2, the contact area between the second protrusion 153 and the lateral portion of the lower portion of the heel is small, and the second protrusion 153 cannot fill the gap between the lateral portion of the lower portion of the heel and the upper 300. As a result, the second protrusion 153 provides poor support and wrapping for the lower portion of the heel. If the length L21 of the second protrusion 153 is greater than 15% of the second protrusion length L2, the second protrusion 153 extends from the lateral portion of the lower portion of the heel to the lower portion of the heel. The second protrusion 153 extending to the lower portion of the heel will make the lower portion of the heel too crowded, resulting in poor wear comfort for the user. When the length L21 of the second protrusion 153 is [10%, 15%] of the length L2 of the second protrusion 15, the second protrusion 153 can fill the gap between the side of the lower portion of the heel and the shoe upper 300, and the second protrusion 153 provides good support and wrapping for the lower portion of the heel. Furthermore, the second protrusion 153 does not extend from the side of the lower portion of the heel to the lower portion of the heel.

[0069] Referring to Figures 1 and 3, in some embodiments, the rear shoe cover 100 further includes a textured structure 191. The textured structure 191 is disposed on the first side 101 of the rear shoe cover 100. In the height direction X of the rear shoe cover 100, the textured structure 191 is disposed in the textured area 19. The textured area 19 is the area of ​​the first side 101 of the rear shoe cover 100 that does not include the protrusion 11. The textured structure 191 and the first protrusion 13 are respectively located on opposite sides of the second protrusion 15.

[0070] In the height direction X of the shoe cover 100, the textured area 19 is located below the second protrusion 15. When the user is wearing shoes, the textured area 19 corresponds to the bottom of the heel (below the lower part of the heel). A textured structure 191 is provided in the textured area 19 and can be evenly or unevenly distributed throughout the textured area 19. The textured structure 191 is used to increase the friction between the shoe cover 100 and the bottom of the heel, thereby further ensuring a more stable fit and preventing the user from slipping off the shoe. The textured structure 191 is a wavy strip-shaped structure. In one embodiment, the textured structure 191 slightly convexly extends from the first side 101 of the shoe cover 100 toward the second side 103 of the shoe cover 100. In this case, the surface of the shoe cover 100 below the second protrusion 15 has an uneven structure, which increases friction with the heel and further prevents the user from slipping off the shoe. In another embodiment, the texture structure 191 is slightly raised and recessed from the first side 101 of the heel cover 100 toward the second side 103 of the heel cover 100, so that the surface of the heel cover 100 below the second protrusion 15 forms an uneven structure, thereby increasing friction with the heel to further prevent the problem of falling off.

[0071] Please refer to FIG. 8 . The shoe 1000 according to the embodiment of the present application includes the shoe rear cover 100 and the shoe upper 300 according to any of the above embodiments. The shoe rear cover 100 is connected to the shoe upper 300 .

[0072] In the shoe rear cover 100 of the embodiment of the present application, the wrapping member 10 protrudes from the first side 31 of the support member 30 toward the second side 33 away from the support member 30, and includes at least two protrusions 11. In the height direction X of the shoe rear cover 100, the protrusions 11 of the higher part fit the upper part of the heel, preventing the upper part of the heel from rubbing against the heel of the shoe, thereby preventing the problem of foot rubbing. The protrusions 11 of the lower part are used to support the lower part of the user's heel, thereby preventing the problem of foot falling off. The shoe rear cover 100 of the present application can solve the problems of foot rubbing and foot falling off at the same time by providing at least two protrusions 11.
