Some people experience blisters when wearing shoes, while others find their shoes slip off easily. Utility Model Content

[0004] This application provides a shoe heel cover and a shoe, which at least solves the problems of rubbing and slipping off the feet when wearing shoes.

[0005] The heel counter of this application includes a support member and a wrapping member. The support member includes a first side and a second side facing away from each other. The wrapping member protrudes from the first side away from the second side. The wrapping member includes a first protrusion and a second protrusion. The first protrusion and the second protrusion are arranged sequentially in the height direction of the heel counter. The height of the wrapping member is the sum of the height of the first protrusion and the height of the second protrusion. The two ends of the first protrusion and the second protrusion are connected so that the surface of the wrapping member facing away from the support member forms a continuous curved surface with its ends connected in the height direction of the heel counter. A groove is provided between the first protrusion and the second protrusion.

[0006] In some embodiments, the first protrusion and the second protrusion surround and together enclose the groove.

[0007] In some embodiments, the length direction of the heel counter is perpendicular to the height direction of the heel counter; the dimension of the groove in the length direction of the heel counter is smaller than the dimension of the first protrusion in the length direction of the heel counter.

[0008] In some embodiments, the length direction of the heel counter is perpendicular to the height direction of the heel counter; the dimension of the groove in the length direction of the heel counter is smaller than the dimension of the second protrusion in the length direction of the heel counter.

[0009] In some embodiments, in the height direction of the heel counter, the first protrusion is higher than the second protrusion; the dimension of the first protrusion in the length direction of the heel counter is smaller than the dimension of the second protrusion in the length direction of the heel counter, and the length direction of the heel counter is perpendicular to the height direction of the heel counter.

[0010] In some embodiments, the heel cover further includes a mesh fabric that wraps around the support and the cover.

[0011] In some embodiments, the maximum height of the second protrusion protruding from the first side is greater than the maximum height of the first protrusion protruding from the first side.

[0012] In some embodiments, the first protrusion includes a first body portion and a first protrusion portion, the first protrusion portion being at least located at one free end of the first protrusion portion, and the height of the first protrusion portion protruding from the first side being greater than the height of the first body portion protruding from the first side; the second protrusion includes a second body portion and a second protrusion portion, the second protrusion portion being at least located at one free end of the second protrusion portion, and the height of the second protrusion portion protruding from the first side being greater than the height of the second body portion protruding from the first side.

[0013] In some embodiments, in the length direction of the heel cover in the unfolded state, the length of the first protrusion is [10%, 15%] of the length of the first protrusion, and the length of the second protrusion is [10%, 15%] of the length of the second protrusion.

[0014] In some embodiments, the heel counter includes a first side and a second side, with the first protrusion and the second protrusion both located on the first side of the heel counter; the heel counter also includes a textured structure disposed in a textured area, the textured area being the region on the first side of the heel counter that does not include the first protrusion and the second protrusion, and the textured structure and the first protrusion being located on opposite sides of the second protrusion, respectively.

[0015] The shoes according to the embodiments of this application include the heel cover and upper as described in any of the above embodiments, wherein the heel cover is connected to the upper.

[0016] In the heel counter of this application, the support member protrudes from a first side of the support member toward a second side away from the support member, and includes at least two protrusions. In the height direction of the heel counter, the higher portion of the protrusion fits against the upper part of the heel, preventing friction between the upper part of the heel and the heel of the shoe, thus avoiding blisters. The lower portion of the protrusion supports the lower part of the user's heel, thereby preventing the shoe from slipping off. By providing at least two protrusions, the heel counter of this application can simultaneously solve the problems of blisters and slipping off.

[0035] Shoes are an indispensable daily necessity. As living standards continue to improve, people's demands for shoe comfort are increasing. Because the shape of the human heel varies, the fit between the heel and the shoe heel differs from person to person. Some people experience blisters when wearing shoes, while others find their shoes slip off. To address this issue, this application provides a shoe heel cover 100 (… Figure 1 (as shown) and shoes 1000 ( Figure 8 (As shown).

[0036] Please see Figures 1 to 3 The shoe heel cover 100 of this application includes a wrapping member 10 and a support member 30. The wrapping member 10 protrudes from the first side 31 of the support member toward the second side 33 away from the support member. The wrapping member 10 includes at least two protrusions 11, which are arranged sequentially in the height direction X of the shoe heel cover 100.

[0037] Specifically, please combine Figure 8 The heel counter 100 is connected to the upper 300 and installed at the heel of the shoe 1000. The heel counter 100 enhances the rigidity of the heel and also provides support and shaping to improve the aesthetics of the shoe 1000. The heel counter 100 improves the overall support and stability of the shoe 1000, preventing foot wobbling and twisting during walking. The connection method between the heel counter 100 and the upper 300 is not limited to stitching or pressing, but ensures a secure connection between the heel counter 100 and the upper 300.

[0038] The support component 30 serves to provide support and shaping, making the heel counter 100 more three-dimensional and improving the overall aesthetics of the shoe 1000. Furthermore, the support component 30 has a certain degree of rigidity, providing good protection for the user's heel when wearing the shoe. In one embodiment, the support component 30 can be made of thermoplastic polyurethane (TPU), EVA solid sponge (ESS), acrylonitrile-butadine-styrene copolymer (ABS), thermosetting polyurethane (PU), or other materials. In this case, the support component 30 has high rigidity and is lightweight.

[0039] In other embodiments, the support member can also be formed from the upper located at the heel of the shoe. In this case, the upper (support member) at the heel is relatively stiff, and the support member can provide better support for the heel counter and also provide better shaping for the shoe. When the support member is formed from the upper at the heel, the heel counter is connected to the support member, thereby providing better support for the user's heel.

[0040] Please see Figures 1 to 3 When the user is wearing the shoe, the first side 31 of the support member is closer to the user's heel than the second side 33 of the support member. The heel is divided into an upper and a lower part along its height. Friction between the upper part of the heel and the top of the shoe heel can easily cause blisters. Since the heel is usually curved, if the lower part of the heel has a smaller curve, the heel can easily separate from the shoe heel, causing the foot to slip off. The wrapper 10 is a structure used to support and wrap the upper and lower parts of the heel. During the user's wearing of the shoe, the wrapper 10 fits snugly against the upper part of the heel, thus preventing blisters caused by friction between the upper part of the heel and the shoe heel. The wrapper 10 also fits snugly against the lower part of the heel, thus preventing the lower part of the heel from separating from the shoe and causing the foot to slip off. The material of the wrapper 10 can be, but is not limited to, foam, latex, or PU. The wrapper 10 is a soft and elastic structure. Because the wrapping component 10 has a certain degree of elasticity, when the user wears the shoes, the wrapping component 10 is compressed and tends to rebound (i.e., return to its initial shape). As a result, the wrapping component 10 can fit tightly to the heel to protect the user's heel and avoid problems such as blisters and slippage.

[0041] The protrusion 11 is a structure designed to support the user's heel; it is soft and elastic. Along the height X direction of the heel counter 100, the higher protrusion 11 conforms to the upper part of the heel to prevent direct contact and friction between the upper part of the heel and the heel counter, thus avoiding blisters. The lower protrusion 11 supports the lower part of the heel, making the shoe more stable and preventing the foot from slipping 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 heel counter 100, the taller protrusion 11 conforms to the upper part of the heel, and the shorter protrusion 11 supports the lower part of the heel. When there are three protrusions 11, in one example, the two taller protrusions 11 conform to the upper part of the heel, and the shorter protrusion 11 supports the lower part of the heel. In another example, the taller protrusion 11 conforms to the upper part of the heel, and the other two shorter protrusions 11 support the lower part of the heel. When there are four protrusions 11, the two taller protrusions 11 conform to the upper part of the heel, and the other two shorter protrusions 11 support the lower part of the heel.

[0043] In the heel counter 100 of this embodiment, the wrapping member 10 protrudes from the first side 31 of the support member toward the second side 33 away from the support member, and includes at least two protrusions 11. In the height direction X of the heel counter 100, the higher portion of the protrusion 11 fits against the upper part of the heel, preventing friction between the upper part of the heel and the heel of the shoe, thus avoiding blisters. The lower portion of the protrusion 11 supports the lower part of the user's heel, thereby preventing the foot from slipping off. The heel counter 100 of this application, by providing at least two protrusions 11, can simultaneously solve the problems of blisters and slipping off.

[0044] The following description, in conjunction with the attached diagram, further explains the heel counter 100.

[0045] Please see Figure 1 and Figure 2In some embodiments, the heel counter 100 further includes a mesh fabric 50, which wraps around the support member 30 and the wrapping member 10. The mesh fabric 50 is a structure used to wrap the support member 30 and the wrapping member 10 to form a complete heel counter 100 and improve the overall aesthetics of the heel counter 100. The heel counter 100 includes a first side 101 and a second side 103 facing away from each other. The first side 101 is closer to the user's heel than the second side 103, and a protrusion 11 is located on the first side 101. The mesh fabric 50 located on the first side 101 is designed to directly conform to the heel. The material of the mesh fabric 50 can be genuine leather or synthetic materials, including, but not limited to, polyester fiber, nylon, or artificial leather. When the material of the mesh fabric 50 is genuine leather, the mesh fabric 50 is more comfortable and breathable, and also has better abrasion resistance. When the mesh fabric 50 is made of synthetic material, it is lightweight and cost-effective. In one embodiment, during the assembly of the heel cover 100, the wrapping component 10 is first placed on the first side 31 of the support component, and then the mesh fabric 50 completely wraps around the support component 30 and the wrapping component 10. In another embodiment, during the assembly of the heel cover 100, the wrapping component 10 is first placed on the first side 31 of the support component, and then the mesh fabric 50 wraps around the wrapping component 10 from both the first side 31 of the support component and the first side 31 of the support component. The method by which the mesh fabric 50 wraps around the support component 30 and the wrapping component 10 is not limited to pressing or sewing.

[0046] Please see Figure 1 and Figure 3 In some embodiments, the package 10 includes a first protrusion 13 and a second protrusion 15. In the height direction X of the shoe 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 the position of the second protrusion 15.

[0047] Specifically, in the height direction X of the heel counter 100, the first protrusion 13 is located near the top of the heel counter 100. When the user wears the shoe, the first protrusion 13 corresponds to the upper part of the heel, and is used to fit against the upper part of the heel, avoiding friction between the upper part of the heel and the top of the shoe heel, thus preventing blisters. Furthermore, because the first protrusion 13 is a soft and elastic structure, it makes the user's wearing experience more comfortable. The number of first protrusions 13 can be, but is not limited to, one, two, three, or more. With only one first protrusion 13, the processing of the heel counter 100 is relatively convenient. With multiple first protrusions 13, the multiple first protrusions 13 are arranged sequentially in the height direction of the heel counter 100, and the multiple first protrusions 13 can be spaced apart or not.

[0048] The second protrusion 15 is further away from the top of the heel counter 100 than the first protrusion 13. When the user is wearing the shoe, the second protrusion 15 corresponds to the lower part of the user's heel, supporting and holding the lower part of the heel, thus making the shoe more stable and preventing the foot from slipping off. Furthermore, because the second protrusion 15 has a soft and elastic structure, it is more comfortable for the user. The number of second protrusions 15 can be, but is not limited to, one, two, three, or more. With only one second protrusion 15, the processing of the heel counter 100 is more convenient. With multiple second protrusions 15, the multiple second protrusions 15 are arranged sequentially in the height direction X of the heel counter 100, and the multiple second protrusions 15 can be spaced apart or not. The number of first protrusions 13 and the number of second protrusions 15 can be the same or different.

[0049] Please see Figure 3 In some embodiments, in the height direction X of the heel cover 100, the height Z1 of the wrapping piece 10 is half the height Z2 of the heel cover 100.

[0050] In the shoe's heel counter 100, along the height direction X, the support piece 10 is located near the top of the heel counter 100. When the height Z1 of the support piece 10 is less than half the height Z2 of the heel counter 100, the support piece 10 cannot properly support the lower part of the heel, resulting in poor support and the shoe easily slipping off the foot. When the height Z1 of the support piece 10 is greater than half the height Z2 of the heel counter 100, the support piece 10 extends downwards below the lower part of the heel, causing the area below the heel to feel cramped and resulting in poor comfort. When the height Z1 of the support piece 10 is half the height Z2 of the heel counter 100, the support piece 10 can simultaneously support both the upper and lower parts of the heel, effectively preventing chafing and slipping off the foot.

[0051] In the height direction X of the heel counter 100, the height Z1 of the wrapping piece 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 piece 10 is close to the top of the heel counter 100, and the height Z1 of the wrapping piece 10 is half the height Z2 of the heel counter 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 avoiding the problem of rubbing against the upper part of the heel and the problem of the lower part of the heel slipping off.

[0052] In the height direction X of the heel counter 100, the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 can be the same. Alternatively, the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 can 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 friction by the heel counter. 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 this application, the height Z11 of the first protrusion 13 and the height Z12 of the second protrusion 15 are the same.

[0053] Please see 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 wrapper 10 and the heel is relatively small. The groove 17 allows for ventilation between the wrapper 10 and the heel, preventing the heel from being completely pressed against the wrapper 10 and causing stuffiness, thus making the shoes more comfortable for the user.

[0054] In other embodiments, when there are multiple first protrusions 13, grooves 17 may also 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 where the wrapper 10 fits against the heel is smaller, and the multiple grooves 17 can make the wrapper 10 more breathable between the wrapper 10 and the heel, making the user's wearing more comfortable.

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

[0056] Specifically, from Figure 2As shown in the cross-sectional view, the first protrusion 13 is an arc-shaped protrusion extending from the first side 31 of the support member. The maximum height H1 of the first protrusion 13 extending from the first side 31 of the support member 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 and the first side 31 of the support member. With the first protrusion 13 being an arc-shaped protrusion extending from the first side 31 of the support member, the first protrusion 13 can better conform to the shape of the foot, making the user's wearing experience more comfortable. The second protrusion 15 is also an arc-shaped protrusion extending from the first side 31 of the support member. The maximum height H2 of the second protrusion 15 extending from the first side 31 of the support member 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 and the first side 31 of the support member. With the second protrusion 15 being an arc-shaped protrusion extending from the first side 31 of the support member, the second protrusion 15 can better conform to the shape of the foot, making the user's wearing experience more comfortable.

[0057] Because the heel has a curve, when a user wears shoes, the lower part of the heel is further away from the heel than the upper part. In other words, the gap between the lower part of the heel and the heel is greater than the gap between the upper part 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 is less than the maximum height H1 of the first protrusion 13 protruding from the first side 31 of the support member, when the user wears shoes, after the first protrusion 13 fits against the upper part of the heel, there will be a gap between the lower part of the heel and the second protrusion 15, so the second protrusion 15 cannot support the lower part of the heel. In this case, the support effect of the wrapping member 10 on the lower part of the user's heel is poor. When the maximum height H2 of the second protrusion 15 protruding from the first side 31 of the self-supporting member is greater than the maximum height H1 of the first protrusion 13 protruding from the first side 31 of the self-supporting member, when the user is wearing shoes, the first protrusion 13 fits against the upper part of the heel, while the second protrusion 15 also supports the lower part of the user's heel. At this time, the support effect of the wrapping member 10 on the user's heel is better.

[0058] Please see Figure 2 , Figure 4 and Figure 5 In some embodiments, the first protrusion 13 includes a first body portion 131 and a first protrusion 133. The first protrusion 133 is at least located at one free end of the first protrusion 13, and the height H12 of the first protrusion 133 protruding from the first side 31 of the support member is greater than the height H11 of the first body portion 131 protruding from the first side 31 of the support member. The second protrusion 15 includes a second body portion 151 and a second protrusion 153. The second protrusion 153 is at least located at one free end of the second protrusion 15, and the height H22 of the second protrusion 153 protruding from the first side 31 of the support member is greater than the height H21 of the second body portion 151 protruding from the first side 31 of the support member.

[0059] In this regard, please combine Figure 8 After the heel counter 100 is connected to the upper 300, the heel counter 100 is a curved structure that can wrap around the foot. Thus, the first protrusion 13 is a curved structure that can wrap around the heel, and the second protrusion 15 is also a curved structure that can wrap around the ankle. The curved first protrusion 13 and the second protrusion 15 can support and wrap around the user's heel, making the user more comfortable to wear.

[0060] Please see Figure 2 and Figure 4 The first protrusion 133 supports the upper side of the heel, preventing direct friction between the upper side of the heel and the shoe upper 300, thus avoiding blisters. When a user wears the shoe, due to differences in foot shape, there will be a gap between the upper side of the heel and the shoe upper 300. If the height H12 of the first protrusion 133 from the first side 31 of the support member is less than or equal to the height H11 of the first body part 131 from the first side 31 of the support member, there may be a gap between the upper side of the heel and the first protrusion 133. This makes it difficult for the first protrusion 133 to fit snugly against the upper side of the heel, resulting in poor support and wrapping for the upper part of the heel. When the height H12 of the first protrusion 133 protruding from the first side 31 of the self-supporting member is greater than the height H11 of the first body part 131 protruding from the first side 31 of the self-supporting member, the first protrusion 133 can fill the gap between the upper side position of the heel and the shoe upper 300, so that the first protrusion 13 has good wrapping and support for the upper side position of the heel, and the user's shoes are more stable, which can avoid the problem of the foot falling off.

[0061] In one embodiment, the first protrusion 13 has a first protrusion 133. In this case, the first protrusion 133 can be located at either of the two free ends of the first protrusion 13. This arrangement of the first protrusion 13 saves foam material. In another embodiment, the first protrusion 13 has two first protrusions 133. The two first protrusions 133 are respectively located at the two free ends of the first protrusion 13. In this case, the first protrusion 13 can prevent the shoe upper 300 from rubbing against the upper side of the heel, and the first protrusion 13 provides better support for the upper part of the heel, making the shoe more stable and comfortable for the user. The first protrusion 13 of this application includes two first protrusions 133.

[0062] Please see Figure 2 and Figure 5The second protrusion 153 supports the lower side of the heel, filling the gap between the lower side of the heel and the upper 300, thus making the shoe more stable and preventing the foot from slipping off. When the height H12 of the second protrusion 153 protruding from the first side 31 of the support member is less than or equal to the height H11 of the second body part 151 protruding from the first side 31 of the support member, the second protrusion 153 may not be able to fill the gap between the lower side of the heel and the upper 300 when the user is wearing the shoe, resulting in poor support and fit for the lower side of the heel. When the height H22 of the second protrusion 153 protruding from the first side 31 of the support member is greater than the height H21 of the second body part 151 protruding from the first side 31 of the support member, the second protrusion 153 can fill the gap between the lower side of the heel and the upper 300, thus making the shoe more stable and preventing the foot from slipping off. At this point, the second protrusion 153 provides better wrapping and support to the lower side of the heel.

[0063] In one embodiment, the second protrusion 15 has a second protrusion 153. In this case, the second protrusion 153 can be located at either of the two free ends of the second protrusion 15. This arrangement of the second protrusion 15 saves foam material. In another embodiment, the second protrusion 15 has two second protrusions 153. The two second protrusions 153 are respectively located 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, making the shoe more stable for the user, preventing the foot from slipping off, and increasing user comfort. The second protrusion 15 of this application includes two second protrusions 153.

[0064] Please see Figure 2 and Figure 6 In some embodiments, the height H22 of the second protrusion 153 protruding from the first side 31 of the support member is greater than the height H12 of the first protrusion 133 protruding from the first side 31 of the support member. In this case, the second protrusion 153 provides better support for the lower part of the heel, and the second protrusion 153 can completely fill the gap between the lower side of the heel and the upper 300, so that the user can wear the shoe more stably and will not experience the problem of the foot slipping off.

[0065] Please see Figure 7 In some embodiments, in the length direction Y of the shoe back cover 100 in the unfolded state, the length L11 of the first protrusion 133 is [10% or 15%] of the length L1 of the first protrusion 13, and the length L21 of the second protrusion 153 is [10% or 15%] of the length L2 of the second protrusion 15.

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

[0067] When 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 upper side of the heel is small, and the first protrusion 133 cannot fill the upper side of the heel and the shoe upper 300. Figure 7 The gap between the first protrusion 133 and the upper part of the shoe (as shown) results in poor support and wrapping of the upper part of the heel. When 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 side of the upper part of the heel to the upper part of the heel. This extension of the first protrusion 133 to the upper part of the heel makes the upper part of the heel too crowded when wearing the shoe, resulting in poor user 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 part of the heel and the upper part of the shoe 300, providing good support and wrapping of the upper part of the heel. Furthermore, the first protrusion 133 does not extend from the side of the upper part of the heel to the upper part of the heel.

[0068] When the length L21 of the second protrusion 153 is less than 10% of the length L2 of the second protrusion, the contact area between the second protrusion 153 and the side of the lower part of the heel is small. The second protrusion 153 cannot fill the gap between the side of the lower part of the heel and the upper 300, resulting in poor support and fit for the lower part of the heel. When the length L21 of the second protrusion 153 is greater than 15% of the length L2 of the second protrusion, the second protrusion 153 extends from the side of the lower part of the heel to the lower part of the heel. This extension makes the lower part of the heel too crowded, resulting in poor 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 lower side of the heel and the upper 300, and the second protrusion 153 provides good support and wrapping for the lower part of the heel. Furthermore, the second protrusion 153 does not extend from the lower side of the heel to the lower part of the heel.

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

[0070] In this design, a textured area 19 is located below the second protrusion 15 along the height direction X of the heel counter 100. When the user is wearing the shoe, 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 the textured structure 191 can be evenly or non-evenly distributed in the textured area 19. The textured structure 191 increases the friction between the heel counter 100 and the bottom of the heel, thereby further ensuring a more stable fit and preventing the shoe from slipping off. The textured structure 191 is a wavy stripe structure. In one embodiment, the textured structure 191 slightly protrudes from the first side 101 of the heel counter towards the second side 103, away from the heel counter. In this case, the surface of the heel counter 100 below the second protrusion 15 has an uneven structure, which increases friction with the heel and further prevents the shoe from slipping off. In another embodiment, the textured structure 191 is slightly raised and recessed from the first side 101 of the heel cover toward the second side 103 of the heel cover, 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 foot from slipping off.

[0071] Please see Figure 8 The shoe 1000 of this application includes the heel cover 100 and the upper 300 of any of the above embodiments, and the heel cover 100 is connected to the upper 300.

[0072] In the heel counter 100 of this embodiment, the wrapping member 10 protrudes from the first side 31 of the support member toward the second side 33 away from the support member, and includes at least two protrusions 11. In the height direction X of the heel counter 100, the higher portion of the protrusion 11 fits against the upper part of the heel, preventing friction between the upper part of the heel and the heel of the shoe, thus avoiding blisters. The lower portion of the protrusion 11 supports the lower part of the user's heel, thereby preventing the foot from slipping off. The heel counter 100 of this application, by providing at least two protrusions 11, can simultaneously solve the problems of blisters and slipping off.
