Description
TECHNICAL FIELD
[0001] The present application relates to the field of shoes, in particular to a shoe sole and a shoe. BACKGROUND
[0002] As an indispensable wearing accessory in human daily life, the core function of a shoe is to provide necessary protection for human feet and also to add decorative and fashionable sense of personal style. However, in real life, the shape of each person's feet is unique, even if the length of the feet is the same, the width of the feet will also be different. If a shoe with appropriate width is found, the length of the feet will not be appropriate, which results in lower comfort of the shoe for some people. CONTENT OF THE UTILITY MODEL
[0003] The purpose of the present application is to provide a shoe sole and a shoe which can stretch in the width direction.
[0004] In order to achieve the above purpose, the following technical solutions are adopted:
[0005] The first technical solution relates to a shoe sole, which is provided with a first groove, the first groove extends in the front-rear direction and is at least open to the bottom surface of the shoe sole.
[0006] The second technical solution is based on the first technical solution, wherein the shoe sole is further provided with a second groove, the second groove extends in the left-right direction and is at least open to the bottom surface of the shoe sole.
[0007] The third technical solution is based on the second technical solution, wherein the number of the first grooves is at least two, the at least two first grooves are arranged in the left-right direction, and the second groove is arranged between the at least two first grooves arranged in the left-right direction.
[0008] The fourth technical solution is based on the third technical solution, wherein the number of the second grooves is at least two, the at least two second grooves are arranged in the front-rear direction, and the first groove is arranged between the at least two second grooves arranged in the front-rear direction.
[0009] The fifth technical solution is based on the fourth technical solution, wherein each first groove and each second groove is located at the part of the shoe sole corresponding to the foot sole.
[0010] The sixth technical solution is based on the fifth technical solution, wherein the second groove is provided with a groove wall in the front-rear direction, an included angle is formed between the groove wall and the surface of the shoe sole, and the included angle is an obtuse angle.
[0011] The seventh technical solution is based on the sixth technical solution, wherein the angle of the included angle is larger closer to the left and right sides of the shoe.
[0012] The eighth technical solution relates to a shoe, which comprises a shoe upper and any one of the shoe soles according to the first technical solution to the sixth technical solution.
[0013] The ninth technical solution is based on the eighth technical solution, wherein the vamp material is a knitted fabric.
[0014] The tenth technical solution is based on the ninth technical solution, wherein the sole material is an EVA material.
[0015] Compared with the prior art, the above-mentioned solutions have the following beneficial effects:
[0016] In the first technical solution, the first slot is arranged on the sole and extends in the front-rear direction. When the width of the sole needs to be adjusted, the arrangement of the first slot makes the sole more likely to deform in the left-right direction. Compared with the sole without the first slot, the arrangement of the first slot is beneficial to adjusting the width of the sole and enables the sole to stretch and contract in the width direction.
[0017] In the second technical solution, the second slot is arranged on the sole and extends in the left-right direction. When the length of the sole needs to be adjusted, the arrangement of the second slot makes the sole more likely to deform in the front-rear direction. Compared with the sole without the second slot, the arrangement of the second slot is beneficial to adjusting the length of the sole.
[0018] In the third technical solution, the number of the first slots is at least two, and the at least two first slots are arranged in the left-right direction. The more the number of the first slots in the left-right direction of the sole, the greater the width that the first slots can deform. The third technical solution is beneficial to increasing the width that the shoe can adjust.
[0019] In the third technical solution, the second slot is arranged between the at least two first slots arranged in the left-right direction, so that the second slot is sandwiched between the first slots. Due to the reduction of the area of the sole between the two first slots, the third technical solution is beneficial to making the sole more likely to deform in the left-right direction, and also makes the sole more likely to deform in the front-rear direction between the two first slots.
[0020] In the fourth technical solution, the number of the second slots is at least two, and the at least two second slots are arranged in the front-rear direction. The more the number of the second slots in the length direction of the sole, the greater the length that the second slots can deform. The fourth technical solution is beneficial to increasing the length that the shoe can adjust.
[0021] In the fourth technical solution, the first slot is arranged between the at least two second slots arranged in the front-rear direction, and the first slot is arranged between the at least two first slots arranged in the left-right direction, so that at least two adjacent second slots in the front-rear direction and at least two adjacent first slots in the left-right direction together form a quadrilateral. The left-right and front-rear stretching of the sole is due to the unstable characteristics of the quadrilateral, which is beneficial to making the sole more likely to deform.
[0022] In the fifth technical solution, the arrangement of the first slot and the second slot can increase the deformation ability of the sole. The arrangement of the first slot and the second slot at the instep can increase the flexibility of the sole at the instep, which is in line with ergonomics.
[0023] In the sixth technical solution, an included angle is formed between the groove wall and the surface of the sole, and the included angle is obtuse. Since the first groove and the second groove are both open to the sole, it is easy for sand or other small objects to enter. If an obtuse angle is formed between the groove wall and the surface of the sole, compared with a right angle formed between the groove wall and the surface of the sole, it is beneficial to reduce the entry of sand or other small objects into the shoe and match the human forefoot bending characteristics, and it is beneficial to increase the flexibility of the sole at the foot.
[0024] In the seventh technical solution, the angle of the included angle is larger closer to the left and right side edges of the shoe. When the foot is bent, the bottom of the foot usually needs to be powered to drive the bending. The larger the included angle of the side edge of the foot, the more convenient the foot bending is, and the flexibility of the sole is increased.
[0025] In the ninth technical solution, the upper material is a knitted fabric. The knitted fabric itself has high elasticity, and is more easy to stretch the shoe in cooperation with the sole. BRIEF DESCRIPTION OF DRAWINGS

[0043] Example
[0044] Figure 1 The shoe 1 in this embodiment is shown, as follows: Figure 1 As shown, shoe 1 includes sole 2 and upper 3, with sole 2 and upper 3 fixedly connected. Figure 2 The sole 2 in this embodiment is shown, as follows: Figure 2 As shown, the sole 2 has several first grooves 4 and several second grooves 5, and the sole 2 includes a quadrilateral 6. The first grooves 4 extend in the front-to-back direction and open onto the bottom surface of the sole 2, while the second grooves 5 extend in the left-to-right direction and open onto the bottom surface of the sole 2. Some of the second grooves 5 also open onto the sides of the sole 2. Both the first grooves 4 and the second grooves 5 are located on the parts of the sole 2 corresponding to the ball of the foot. Figure 2As shown, the first groove 4 is arranged at horizontal intervals and at front-to-back intervals in the vertical direction. A second groove 5 is provided between two adjacent horizontally arranged first grooves 4, and between two adjacent front-to-back arranged first grooves 4. A second groove 5 is provided between the first groove 4 near the side of the shoe 1 and the side of the shoe 1, with part of the second groove 5 opening onto the side of the shoe 1. (See diagram) Figure 2 As shown, quadrilateral 6 is a solid area enclosed by two adjacent first grooves 4 along the left-right direction and two adjacent second grooves 5 along the front-back direction. This enclosement does not mean that the two first grooves 4 and the two second grooves 5 are connected to each other. The four sides of quadrilateral 6 are not closed.
[0045] Figure 3 The groove wall 7 in this embodiment is shown, as follows: Figure 3 As shown, the second groove 5 is provided with a groove wall 7, which is set in the front-back direction of the second groove 5. The groove wall 7 forms an angle 8 with the surface of the sole 2. The angle 8 is an obtuse angle, which means that the second groove 5 is tilted forward, which can better match the bending characteristics of the forefoot and conforms to ergonomics. Figure 4 and Figure 5 This embodiment shows the groove wall 7 located in the center and near the side of the sole 2. Figure 4 The included angle of 8 degrees is 127°. Figure 5 The included angle 8 is 130°. It can be seen that the included angle 8 is larger the closer it is to the side of the shoe 1. In other embodiments, the included angle 8 can also be of other degrees. Figure 6 The widened sole 2 in this embodiment is shown. Figure 7 The elongated sole 2 in this embodiment is shown, as follows: Figure 6 and Figure 7 As shown, when the sole 2 is widened, the width of the first groove 4 is widened, the quadrilateral 6 is deformed and widened laterally at the same time, and when the sole 2 is elongated, the width of the second groove 5 is widened, the quadrilateral 6 is deformed and elongated longitudinally at the same time.
[0046] The sole 2 is made of EVA material, which is lightweight, making walking in the shoe 1 easier. The upper 3 is made of knitted fabric. In this embodiment, the upper 3 is a one-piece knitted upper, making it lighter, more elastic, and easier to put on and take off. It also reduces the risk of wear and tear due to poor fit by minimizing stitching. In this embodiment, the sole 2 and upper 3 are glued together, but the glue does not completely seal the opening at the second groove 5 on the side of the sole 2, ensuring that the second groove 5 can stretch and contract. In this embodiment, each first groove 4 and each second groove 5 is achieved through discontinuous longitudinal and transverse cutting and hot-cutting processes along the forefoot flexion area of the sole 2. After wearing this product, the user can adapt and adjust the shoe 1 according to their foot shape. The instability of the quadrilateral 6 facilitates adjustment of the shoe 1's length and width.
[0047] In this embodiment, the first groove 4 is provided on the sole 2 and extends in the front-to-back direction. When it is necessary to adjust the width of the sole 2, the provision of the first groove 4 makes it easier for the sole 2 to deform in the left-to-right direction. Compared with the sole 2 without the first groove 4, it is beneficial to adjust the width of the sole 2 and enables the sole 2 to stretch and contract in the width direction.
[0048] In this embodiment, the second groove 5 is provided on the sole 2 and extends in the left and right direction. When it is necessary to adjust the length of the sole 2, the provision of the second groove 5 makes it easier for the sole 2 to deform in the front and back direction. Compared with the sole 2 without the second groove 5, it is beneficial to adjust the length of the sole 2.
[0049] In this embodiment, the number of first grooves 4 is at least two and at least two first grooves 4 are arranged in the left and right direction. The more first grooves 4 there are in the left and right direction of the sole 2, the greater the width that can be deformed, which is beneficial to increasing the width that the shoe 1 can adjust.
[0050] In this embodiment, a second groove 5 is provided between at least two first grooves 4 arranged in the left-right direction, so that the second groove 5 is sandwiched between the first grooves 4. Since the area of the sole 2 between the two first grooves 4 is reduced, it is easier for the sole 2 to deform in the left-right direction, and it is also easier for the sole 2 to deform in the front-back direction between the two first grooves 4.
[0051] In this embodiment, the number of second grooves 5 is at least two and at least two second grooves 5 are arranged in the front-back direction. The more first grooves 4 there are in the length direction of the sole 2, the greater the length that can be deformed, which is beneficial to increasing the adjustable length of the shoe 1.
[0052] In this embodiment, at least two second grooves 5 arranged in the front-back direction are spaced apart by a first groove 4, and at least two first grooves 4 arranged in the left-right direction are spaced apart by a first groove 4, so that at least two adjacent second grooves 5 in the front-back direction and two adjacent first grooves 4 in the left-right direction together form a quadrilateral 6. When the sole 2 is stretched left-right and front-back, due to the unstable nature of the quadrilateral 6, the sole 2 is more likely to deform.
[0053] In this embodiment, the first groove 4 and the second groove 5 can increase the deformation capability of the sole 2. The first groove 4 and the second groove 5 at the foot can increase the flexibility of the sole 2 at the foot, which is in line with ergonomics.
[0054] In this embodiment, an angle 8 is formed between the groove wall 7 and the surface of the sole 2. The angle 8 is an obtuse angle. Since both the first groove 4 and the second groove 5 open into the sole 2, it is easy for mud or other small objects to enter. If an obtuse angle is formed between the groove wall 7 and the surface of the sole 2, compared to a right angle, it is beneficial to reduce the entry of mud or other small objects into the shoe 1 and matches the bending characteristics of the forefoot, which is beneficial to increase the flexibility of the sole 2 at the foot.
[0055] In this embodiment, the angle 8 closer to the left and right sides of the shoe 1 is larger. When the foot bends, the bottom of the foot usually needs to exert force to drive the bend. The larger the angle 8 of the foot side, the easier it is to bend the foot, thus increasing the flexibility of the sole 2.
[0056] In this embodiment, the upper 3 is made of knitted fabric, which has high elasticity and, when combined with the sole 2, makes it easier to stretch the shoe 1.
[0057] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
