Description

Technical Field

[0001] This utility model relates to the field of footwear, specifically to a shoe sole and a shoe. Background Technology

[0002] During footwork, the sole of a shoe needs to flex and straighten with each step. However, traditional soles, especially thicker ones, have high flexural stiffness due to their high material hardness (such as high-density EVA and PU) and high bending rigidity. This results in greater flexural resistance, requiring the shoe to overcome greater material stress during bending, increasing muscle compensation (Achilles tendon tension increases by 15%-20%), which can easily lead to calf fatigue and poor comfort. Furthermore, traditional soles cannot meet the different needs of heel strike stability, midfoot support transition, and forefoot push-off flexibility. Long-term wear may lead to abnormal joint pressure, and the heavier soles increase energy consumption during exercise. Utility Model Content

[0043] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] The following is for reference. Figures 1-5 Describes a shoe sole and shoe according to an embodiment of the present utility model.

[0045] like Figures 1-5 As shown, the sole of this embodiment of the invention includes a sole body 1.

[0046] The sole body 1 includes components along the length direction of the sole body 1 (e.g., Figure 1 and Figure 2 The forefoot portion 11, midfoot portion 12, and heel portion 13 are arranged sequentially from right to left (as shown). When the sole is worn, the forefoot portion 11, midfoot portion 12, and heel portion 13 correspond one-to-one with the forefoot, midfoot, and heel of the foot. In other words, the forefoot portion 11 is located under the forefoot, the midfoot portion 12 is located under the midfoot, and the heel portion 13 is located under the heel.

[0047] The bottom surface of the sole body 1 is provided along the width direction of the sole body 1 (e.g., Figure 1 As shown, grooves 2 extend in the vertical direction and are spaced apart along the length of the sole body 1. Figure 1 As shown, the groove 2 is provided on the bottom surface of the sole body 1; in other words, the groove 2 is provided on the contact surface of the sole body 1. The groove 2 extends along the width direction of the sole body 1, preferably but not limited to penetrating the sole body 1. In this embodiment, the groove 2 is provided penetrating the sole body 1 along the width direction to further reduce the resistance of the sole body 1 when bending at this point. The groove 2 is preferably, but not limited to, multiple grooves, which are arranged at intervals in the left-right direction.

[0048] At least a portion of the groove 2 has a groove depth that is at least one-third of the thickness of the sole body 1 where the groove 2 is located, and is provided in at least one of the forefoot portion 11, the midfoot portion 12, and the heel portion 13. For example... Figure 2 As shown, the groove depth of groove 2 is along the thickness direction of the sole body 1 (e.g., Figure 2 The groove 2, as shown in the vertical direction, has a constant depth along the width of the sole body 1. The depth of all or part of the groove 2 is at least one-third of the thickness H of the sole body 1 where the groove 2 is located. This groove 2 is deeper than grooves in related technologies, making it easier for the sole body 1 to flex and achieve a greater degree of flex at the location of the groove 2. This deeper groove 2, compared to related technologies, is located in at least one of the forefoot portion 11, midfoot portion 12, and heel portion 13. In other words, the groove 2, with a depth of at least one-third of the thickness of the sole body 1 where the groove 2 is located, is located in one, two, or all three of the forefoot portion 11, midfoot portion 12, and heel portion 13. This allows the sole to flex to different degrees according to the foot movement posture during the three phases: heel strike, midfoot support, and forefoot push-off.

[0049] In this embodiment of the invention, at least one of the forefoot portion 11, midfoot portion 12, and heel portion 13 is provided with a groove 2 whose depth is at least one-third of the thickness of the sole body 1 where the groove 2 is provided. This makes it easier for the sole body 1 to bend at the location where the groove 2 is provided and allows for a greater degree of bending. As a result, the sole can bend to different degrees according to the posture of the foot movement during the three stages of heel strike, midfoot support, and forefoot push-off.

[0050] In some embodiments, the grooves 2 are provided as a plurality of grooves 2, including a first groove 21 located in the forefoot portion 11, a second groove 22 located in the midfoot portion 12, and a third groove 23 located in the heel portion 13. The groove depth of at least one of the first groove 21, the second groove 22 and the third groove 23 is at least one-third of the thickness of the sole body 1 where the grooves 2 are provided.

[0051] like Figure 2 As shown, the first groove 21, the second groove 22 and the third groove 23 can be configured such that the groove depth of one of them is at least one-third of the thickness of the sole body 1 where the groove 2 is located, and the groove depth of the groove 2 is greater than the groove depth of the other two of the first groove 21, the second groove 22 and the third groove 23.

[0052] The first groove 21, the second groove 22, and the third groove 23 can also be configured such that the groove depth of two of them is at least one-third of the thickness of the corresponding groove 2 in the sole body 1, and the groove depth of the two grooves 2 is greater than the groove depth of the remaining one of the first groove 21, the second groove 22, and the third groove 23.

[0053] The groove depths of the first groove 21, the second groove 22, and the third groove 23 can all be set to be at least one-third of the thickness of the corresponding groove 2 on the sole body 1. Alternatively, one or both of the groove depths can be set to be at least one-third of the thickness of the corresponding groove 2 on the sole body 1. In other words, one or both of the groove depths are less than one-third of the thickness of the corresponding groove 2 on the sole body 1.

[0054] Thus, the groove depths of the first groove 21, the second groove 22, and the third groove 23 are different, allowing the forefoot 11, midfoot 12, and heel 13 to produce different degrees of flexion, so that the sole can produce different degrees of flexion according to the posture of the foot movement during the three stages of heel strike, midfoot support, and forefoot push-off.

[0055] In some embodiments, the groove depth of the first groove 21 is at least one-third of the thickness of the sole body 1 where the first groove 21 is provided, the groove depth of the third groove 23 is at least one-third of the thickness of the sole body 1 where the third groove 23 is provided, and the groove depth of the second groove 22 is less than the groove depths of the first groove 21 and the third groove 23.

[0056] like Figure 2 As shown, the groove depth of the first groove 21 of the forefoot portion 11 is h1, the groove depth of the second groove 22 of the midfoot portion 12 is h2, and the groove depth of the third groove 23 of the heel portion 13 is h3.

[0057] The groove depth h1 of the first groove 21 is at least one-third of the thickness H of the sole body 1 where the first groove 21 is located. The groove depth h3 of the third groove 23 is at least one-third of the thickness H of the sole body 1 where the third groove 23 is located. The groove depth h2 of the second groove 22 can be at least one-third of the thickness H of the sole body 1 where the second groove 22 is located, or it can be less than one-third of the thickness H of the sole body 1 where the second groove 22 is located. However, the groove depth h2 of the second groove 22 is less than the groove depth h1 of the first groove 21 and the groove depth h3 of the third groove 23.

[0058] When the sole is worn and moves with the foot, the first groove 21, the second groove 22 and the third groove 23 enable the forefoot 11, the midfoot 12 and the heel 13 to perform different degrees of flexion and extension movements during walking.

[0059] Specifically, the first groove 21 makes the forefoot part 11 easier to bend during foot movement, reducing the bending resistance when the forefoot pushes off, thereby promoting normal dorsiflexion of the metatarsophalangeal joint, improving push-off efficiency, reducing fatigue in the lower leg, providing stable support, reducing exercise energy consumption, and making the foot feel more comfortable.

[0060] The second groove 22 enhances the torsional resistance of the sole body 1, preventing the sole body 1 from collapsing during foot movement, and provides stable support for the arch of the foot in the midfoot 12 during foot movement, maintaining gait balance. It also has the functions of drainage, anti-slip and expelling foreign objects, improving the feel of the foot.

[0061] The third groove 23 enables the heel portion 13 to cushion the impact of the ground when the heel strikes the ground during foot movement, reducing the load on the Achilles tendon and knee joint, and providing stable support.

[0062] The first groove 21, the second groove 22 and the third groove 23 give the sole high flexibility and comfort, and reduce the risk of sports injuries.

[0063] In some embodiments, the groove depth h1 of the first groove 21 is 40% to 60% of the thickness H of the sole body 1 where the first groove 21 is provided, such as 40%, 45%, 50%, 55%, 60%, etc., preferably 45%. Figure 2 As shown. This allows the forefoot portion 11 to bend easily during foot movement, reducing flexion resistance during forefoot extension, promoting normal dorsiflexion of the metatarsophalangeal joint, improving extension efficiency, reducing fatigue in the lower leg, providing stable support, reducing energy consumption during exercise, and making the foot feel more comfortable.

[0064] In some embodiments, the groove depth h2 of the second groove 22 is 0% to 40% of the thickness H of the sole body 1 where the second groove 22 is provided, for example, 0%, 10%, 20%, 30%, 40%, etc., preferably 25%. Figure 2 As shown. It should be noted that when the groove depth h2 of the second groove 22 is 0% of the thickness H of the sole body 1 where the second groove 22 is provided, the groove depth h2 of the second groove 22 is 0mm. This improves the torsional resistance of the sole body 1, prevents the sole body 1 from collapsing during foot movement, and provides stable support for the arch of the foot in the midfoot 12 during foot movement, maintaining gait balance. It also has the functions of drainage, anti-slip, and foreign object removal, improving the feel of the foot.

[0065] In some embodiments, the groove depth of the third groove 23 is 30% to 50% of the thickness of the sole body 1 where the third groove 23 is provided, such as 30%, 35%, 40%, 45%, 50%, etc., preferably 40%. Figure 2 As shown. This is so that the heel portion 13 can cushion the impact of the heel striking the ground during foot movement, reduce the load on the Achilles tendon and knee joint, and provide stable support.

[0066] It should be noted that the thickness H of the sole body 1 is preferably, but not limited to, increasing from right to left.

[0067] In some embodiments, the ratio of the maximum groove width to the groove depth of the first groove 21 is 1:2.0 to 1:4.0.

[0068] like Figure 2 As shown, the ratio of the maximum groove width w1 to the groove depth h1 of the first groove 21 is 1:2.0 to 1:4.0, for example 1:2.0, 1:2.3, 1:2.6, 1:2.8, 1:3.0, 1:3.3, 1:3.6, 1:3.8, 1:4.0, preferably 1:2.65.

[0069] In some embodiments, the ratio of the maximum width to the depth of the second groove 22 is 1:0.7 to 1:1.

[0070] like Figure 2As shown, the ratio of the maximum groove width w2 to the groove depth h2 of the second groove 22 is 1:0.7 to 1:1, for example, 1:0.7, 1:0.8, 1:0.9, 1:1, preferably 1:0.8. It should be noted that when the ratio of the maximum groove width w2 to the groove depth h2 of the second groove 22 is 1:1, the groove width w2 and the groove depth h2 are equal, and the groove width w2 and the groove depth h2 ≥ 0 mm.

[0071] In some embodiments, the ratio of the maximum width to the depth of the third groove 23 is 1:2.0 to 1:4.0.

[0072] like Figure 2 As shown, the ratio of the maximum groove width w3 to the groove depth h3 of the third groove 23 is 1:2.0 to 1:4.0, for example 1:2.0, 1:2.3, 1:2.6, 1:2.8, 1:3.0, 1:3.3, 1:3.6, 1:3.8, 1:4.0, preferably 1:2.65.

[0073] Therefore, the groove depth h2 of the second groove 22 is less than the groove depth h1 of the first groove 21 and the groove depth h3 of the third groove 23. Meanwhile, as... Figure 2 As shown, the cross-sectional shape of the second groove 22 is shallower and wider than that of the first groove 21 and the third groove 23, which further provides stable support for the arch of the foot and prevents the sole body 1 from collapsing.

[0074] In other embodiments, the groove depth h2 of the second groove 22 may also be equal to the groove depth h1 of the first groove 21 and the groove depth h3 of the third groove 23. It is not limited to this, as long as the groove depth of at least one of the first groove 21, the second groove 22 and the third groove 23 is at least one-third of the thickness of the sole body 1.

[0075] In some embodiments, the groove widths of the first groove 21, the second groove 22, and the third groove 23 increase in the direction toward the bottom surface of the sole body 1, and the positions where the first groove 21, the second groove 22, and the third groove 23 have the maximum groove width are all located on the bottom surface of the sole body 1.

[0076] like Figure 2 As shown, the widths of the first groove 21, the second groove 22, and the third groove 23 all increase from top to bottom. Therefore, the positions where the first groove 21, the second groove 22, and the third groove 23 have the maximum groove width are all located on the bottom surface of the sole body 1. In other words, the maximum groove widths of the first groove 21, the second groove 22, and the third groove 23 are formed on the bottom surface of the sole body 1.

[0077] It is understood that, in some other embodiments, the positions where the first groove 21, the second groove 22, and the third groove 23 have the maximum groove width can be located at the middle in the vertical direction, and in still other embodiments, the groove widths of the first groove 21, the second groove 22, and the third groove 23 can be constant in the vertical direction.

[0078] In some embodiments, the second groove 22 extends from the bottom surface of the sole body 1 toward the top surface of the sole body 1 and is inclined toward the forefoot portion 11.

[0079] like Figure 2 As shown, the second groove 22 extends from bottom to top and is inclined from left to right. Specifically, the center line L2 of the second groove 22 extends from bottom to top and is inclined from left to right.

[0080] The ratio of the width w2 to the depth h2 of the second groove 22 is set to 1:0.7 to 1:1.0. Simultaneously, the deformation of the second groove 22 during foot movement provides a propulsive effect, enhancing foot feel.

[0081] The first groove 21 and the third groove 23 are preferably, but not limited to, extending vertically in the up-down direction.

[0082] In some embodiments, the angle between the centerline of the second groove 22 and the plane supporting the sole body 1 is β2, and the angle β2 is 45° to 90°.

[0083] like Figure 2 As shown, the angle between the center line L1 of the first groove 21 and the plane G supporting the sole body 1 is β1, the angle between the center line L2 of the second groove 22 and the plane G supporting the sole body 1 is β2, and the angle between the center line L1 of the third groove 23 and the plane G supporting the sole body 1 is β3. β1 and β3 are preferably, but not limited to, 90°, and β2 is 45° to 90°, such as 45°, 50°, 60°, 70°, 80°, 90°, etc., preferably 70° to 80°, such as 70°, 75°, 80°, etc., more preferably 75°.

[0084] In some embodiments, the groove 2 includes a first side 24 and a second side 25, the first side 24 and the second side 25 are disposed opposite to each other along the direction from the heel portion 13 to the forefoot portion 11, and the inclination angle of the second side 25 of the second groove 22 is greater than the inclination angle of the first side 24.

[0085] like Figure 2 As shown, the groove 2 includes a first side 24 and a second side 25 arranged opposite to each other in the left-right direction, with the first side 24 located to the left of the second side 25.

[0086] The first side 24 of the second groove 22 extends from bottom to top and is inclined to the right.

[0087] The second side 25 of the second groove 22 can be configured to extend vertically in the up-down direction, or extend from bottom to top and tilt to the left, or extend from bottom to top and tilt to the right, preferably extending from bottom to top and tilting to the right.

[0088] The angle between the second side 25 of the second groove 22 and the plane G supporting the sole body 1 is γ2, and the angle between the first side 24 of the second groove 22 and the plane G supporting the sole body 1 is γ1, where γ2 > γ1. The plane G supporting the sole body 1 is preferably, but not limited to, the ground.

[0089] The first side 24 of the second groove 22 is tilted to the right to a greater degree than the second side 25 of the second groove 22, which is conducive to the discharge of foreign objects in the second groove 22.

[0090] In some embodiments, the groove 2 includes a first side surface 24, a second side surface 25, and an arc surface 26. The first side surface 24 and the second side surface 25 are arranged at intervals along the length direction of the sole body 1. The arc surface 26 connects the first side surface 24 and the second side surface 25 so that the first side surface 24 and the second side surface 25 are smoothly transitioned. The tangent of the end of the arc surface 26 that connects to the first side surface 24 has an angle α with the tangent of the other end of the arc surface 26 that connects to the second side surface 25.

[0091] like Figure 2 and Figure 3 As shown, the groove 2 also includes an arc surface 26. The first side surface 24 and the second side surface 25 are arranged at intervals in the left and right direction and are positioned opposite each other. The arc surface 26 connects the top of the first side surface 24 and the top of the second side surface 25 so that the first side surface 24 and the second side surface 25 can be smoothly transitioned, thereby dispersing the stress during the bending process and preventing tearing at the groove 2 on the sole body 1.

[0092] The left end of the arc surface 26 connects to the first side surface 24, and the tangent at the left end of the arc surface 26 is L4. The right end of the arc surface 26 connects to the second side surface 25, and the tangent at the right end of the arc surface 26 is L5. There is an angle α between L4 and L5. The angle α is preferably, but not limited to, set to 0° to 45°, such as 0°, 10°, 20°, 30°, 35°, 45°, etc. It should be noted that when the angle α is 0°, L4 and L5 are parallel.

[0093] If the angle α of groove 2 is too large, the groove width of groove 2 will be too large, reducing the bending ability and support of the sole body 1, and making it prone to cracking. If the angle α of groove 2 is too small, the groove width of groove 2 will be too small or even closed, reducing the bending ability of the sole body 1.

[0094] In some embodiments, the angle α of the first groove 21 is 0° to 20°, such as 0°, 5°, 10°, 15°, 20°, etc., preferably 12°. This allows the forefoot portion 11 to bend easily during foot movement and provides stable support.

[0095] In some embodiments, the angle α of the second groove 22 is 0° to 35°, for example, 0°, 5°, 10°, 18°, 20°, 25°, 30°, 35°, etc., so that the midfoot portion 12 provides stable support to the arch of the foot during foot movement and can expel foreign objects that enter the second groove 22.
