Description

Technical Field

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

[0002] Athletic shoes typically consist of an upper, insole, midsole, and outsole. The insole supports the foot, the midsole provides primary cushioning and support, and the outsole handles friction with the ground. Spikes are often used in many sports to improve traction; for example, in tennis, the friction provided by spikes prevents athletes from slipping during short, rapid movements. However, metal spikes are rigid, which can feel uncomfortable during normal walking and negatively impact the wearing experience. Summary of the Invention

[0003] After repeated research, the applicant discovered that in many sports, such as tennis and badminton, athletes need to use rapid, short-range movements to quickly change positions. These rapid movements require athletes to generate a burst of power in their legs that far exceeds that of normal walking. This burst of power, if the shoe sole lacks sufficient grip, can cause athletes to slip. Therefore, athletes need to wear spiked shoes to avoid slipping. However, because the metal spikes are rigid and always directly contact the ground, they also create an unusual feeling during normal walking, affecting the athlete's wearing experience.

[0004] Therefore, the purpose of this application is to provide a sole and a shoe that not only does not cause obvious discomfort when the wearer walks normally, but also provides higher grip when the wearer steps on it with force than when walking normally.

[0005] Solution 1 relates to a shoe sole, wherein it is provided with an outsole and an anti-slip unit. The outsole is provided with a perforation, and the anti-slip unit is provided with a deformation part and a displacement part. The deformation part is annular and located at the perforation, and is adapted to abut against the ground or the outsole. The deformation part also extends along its axial direction away from the ground and converges radially inward. The displacement part is located inside the deformation part and connected to the deformation part. Its end facing the ground is provided with a top abutment part adapted to abut against the ground. When the displacement part is subjected to a first force, it is adapted to move along the axial direction of the deformation part towards the ground so that the top abutment part is exposed on the outsole and the deformation part is elastically deformed. The deformation part is also adapted to recover its deformation and drive the displacement part to move along the axial direction of the deformation part away from the ground so that the top abutment part is not exposed on the outsole. The first force includes at least a component force along the axial direction of the deformation part towards the ground.

[0006] In this technical solution, the outsole has a through hole, and the anti-slip unit has a deformation part and a displacement part. The deformation part is annular and located at the through hole. It also extends along its axial direction away from the ground and converges radially inward. The displacement part is located inside the deformation part, and its end facing the ground has a support part suitable for abutting against the ground. Therefore, when the displacement part is subjected to a first force including the component force along the axial direction of the deformation part towards the ground, the displacement part will be pushed to move along the axial direction of the deformation part towards the ground, so that the support part can pass through the opening formed by the annular deformation part and be exposed on the outsole, thereby abutting against the ground to provide grip. In this process, since the displacement part is connected to the deformation part and the deformation part abuts against the ground or the outsole, the position of the deformation part connected to the displacement part will be driven by the displacement part, so that the deformation part undergoes elastic deformation to store energy. Therefore, the deformation part can also recover elastic deformation to release energy, thereby driving the displacement part to move along the axial direction of the deformation part away from the ground and preventing the support part from being exposed on the outsole. By adjusting the elasticity of the deformation section (e.g., by selecting different materials, as is well known to those skilled in the art), the force applied to the displacement section by the wearer during normal walking is less than the first force. In this case, the deformation section deforms, but the top part cannot protrude from the outsole and thus cannot press against the ground. Therefore, the wearer will not feel any obvious discomfort during normal walking. However, when the wearer exerts force, this force far exceeds the force during normal walking. The force applied to the displacement section is greater than or equal to the first force, which can push the top part out of the outsole and press against the ground to provide grip. The greater the force applied by the wearer, the greater the force of the top part on the ground, and the stronger the grip. Therefore, the wearer can provide higher grip when stepping hard than during normal walking. When the force applied to the displacement section is less than the first force, the deformation section can recover its deformation and drive the top part so that the top part does not protrude from the outsole.

[0007] Scheme 2 is based on Scheme 1, wherein the displacement part is conical and extends along the axial direction of the deformation part, with the top of the cone facing the ground and forming a top abutment part, and the angle between the conical surface of the displacement part and the axial direction of the deformation part is smaller than the angle between the deformation part and the axial direction of the deformation part.

[0008] In this technical solution, the displacement part is conical and extends along the axial direction of the deformation part. Its cone apex faces the ground and forms a top abutment. The cone apex structure is more conducive to providing grip when abutting the ground, while the conical shape itself has high structural stability, which can, to some extent, prevent deformation when abutting the ground. Furthermore, the angle between the conical surface of the displacement part and the axial direction of the deformation part is smaller than the angle between the two axial directions of the deformation part. This allows the deformation part to deform more easily than the displacement part when the force is applied, which is beneficial for moving the displacement part. Simultaneously, it helps prevent deformation of the displacement part, thus avoiding affecting the gripping performance of the top abutment when it contacts the ground.

[0009] Option 3 is based on Option 1, and it also includes a midsole located on the side of the outsole away from the ground. The midsole has a body, a transmission structure, and an anti-slip unit. The connection between the displacement part and the deformation part forms a force-bearing part. The transmission structure and the anti-slip unit are embedded in the body. The transmission structure is located on the side of the anti-slip unit away from the ground. It has an annular expansion part that connects to the force-bearing part. It also extends along the axial direction of the deformation part away from the ground and expands outward along the radial direction of the deformation part.

[0010] In this technical solution, the connection between the displacement part and the deformation part forms a force-bearing part. Applying force to this point can push the displacement part to move. Furthermore, the force-bearing part is located at the position furthest from the outsole within the anti-slip unit, facilitating the application of force. The midsole comprises a body, a transmission structure, and an anti-slip unit. The transmission structure and the anti-slip unit are embedded within the body. The transmission structure is located on the side of the anti-slip unit facing away from the ground and has a ring-shaped expansion part. This expansion part connects to the force-bearing part and extends axially along the deformation part facing away from the ground while expanding radially outwards. Therefore, when a thicker midsole is needed to improve cushioning performance, compared to directly increasing the anti-slip unit to thicken the midsole without a transmission structure (which would increase the displacement part due to the increased anti-slip unit size, causing displacement of the top contact part upon contact with the ground), this solution offers a significant advantage. The previous solutions either involve easily deformable sections, hindering the contact between the upper part and the ground to provide grip, or simply thickening the midsole without a transmission structure or changing the size of the anti-slip unit (which makes it difficult for the body's trotting force to be effectively transmitted to the bearing part, thus hindering the movement of the displacement part). This technical solution thickens the midsole without changing the size of the anti-slip unit, and the transmission structure is embedded within the body. Therefore, when the body is subjected to trotting force towards the ground, it compresses the expansion part, allowing the force to be accurately transmitted to the bearing part without being excessively lost due to cushioning by the body. Furthermore, because the expansion part is annular and embedded with the body both inside and outside, it does not significantly affect the wearer's foot feel. In addition, since the point of force applied when the body steps on the midsole is not always aligned with the bearing part, the expansion part, being approximately a funnel structure, allows the applied force to be effectively transmitted to the bearing part even if it does not correspond to the bearing part but is within the expansion part, thus propelling the displacement part.

[0011] Option 4 is based on Option 3, in which the elasticity of the transfer structure material is greater than that of the body material.

[0012] In this technical solution, by making the elasticity of the transmission structure material greater than that of the body material, the midsole can maintain a certain degree of softness and cushioning performance while the applied force can be effectively transmitted to the force-bearing part so as to drive the displacement part to move.

[0013] Scheme 5 is based on Scheme 3, wherein the angle between the axial directions of the expansion section and the deformation section is smaller than the angle between the axial directions of the deformation section and the deformation section.

[0014] In this technical solution, the angle between the expansion part and the deformation part along the axis is smaller than the angle between the deformation part and the deformation part along the axis. This is beneficial because when force is applied to the midsole, the deformation part deforms first, reducing the situation where the expansion part continues to expand outward under the action of force, thus making it difficult for the force to be effectively transmitted to the force-bearing part.

[0015] Scheme 6 is based on Scheme 3. In this scheme, the transmission structure is further provided with a first cone and a second cone extending along the axial direction of the deformation part. The cone apexes of the first cone and the second cone are opposite to each other along the axial direction of the deformation part and connected to each other. The cone bottom of the first cone is connected to the force-bearing part. The expansion part surrounds the first cone and the second cone, and its two ends along the axial direction of the deformation part are respectively connected to the cone bottoms of the first cone and the second cone.

[0016] In this technical solution, the transmission structure also includes a first cone and a second cone extending axially along the deformable portion. The first and second cones are opposite to and connected to each other along the axial direction of the deformable portion. The bottom of the first cone is connected to the force-bearing portion, and the expansion portion surrounds the first and second cones. Its two ends along the axial direction of the deformable portion are respectively connected to the bottoms of the first and second cones. Therefore, the force applied to the middle bottom can be transmitted not only through the expansion portion but also through the first and second cones to the force-bearing portion. Furthermore, since the first and second cones are also connected to the expansion portion, it helps to reduce the situation where the expansion portion continues to expand outward under stress, thus reducing the dispersion of force.

[0017] Scheme 7 is based on Scheme 6, wherein the first cone and the displacement part are both hollow structures, and the first cone and the displacement part enclose each other to form an accommodating space.

[0018] In this technical solution, both the first cone and the displacement part are hollow structures. The cone bottoms of the first cone and the displacement part enclose each other to form an accommodating space. Therefore, the main body can be filled into the accommodating space to provide a certain buffer when the top part hits the ground, so as to avoid excessive foot discomfort.

[0019] Option 8 is based on Option 6, and it also includes an insole. The insole is located on the side of the midsole that is away from the ground and covers the body and transmission structure. The second cone is a hollow structure, and the insole abuts against the second cone and the expansion section.

[0020] In this technical solution, by adding an insole, which is located on the side of the midsole away from the ground and covers the body and transmission structure, the second cone is a hollow structure. The insole abuts against the second cone and the expansion part, so the body can be filled into the second cone, and the human foot will not directly contact the transmission structure, which helps to reduce the wearer's sense of discomfort.

[0021] Option 9 is based on Option 1, in which the outsole is also provided with several anti-slip protrusions. The anti-slip protrusions protrude towards the ground side. When the deformable part is not deformed, the top abutment part is located between the end and the bottom of the anti-slip protrusion along the axial direction of the deformable part.

[0022] In this technical solution, the outsole is also provided with several anti-slip protrusions, which can provide a certain grip even when the top abutment is not exposed on the outsole. When the deformable part is not deformed, the top abutment is located between the end and bottom of the anti-slip protrusion along the axial direction of the deformable part, so that the top abutment only needs to move a small distance to expose the outsole and abut against the ground.

[0023] Option 10 relates to a shoe, which includes an upper and a sole as described in any of Options 1 to 9. Attached Figure Description

Detailed Implementation

[0030] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and accompanying drawings of this application is for the purpose of distinguishing different objects, not for describing a specific order.

[0031] Unless otherwise specified, in the claims and description, the terms "comprising," "having," and variations thereof mean "including but not limited to."

[0032] In the claims and description, unless otherwise specified, the term "have" means that a technical feature that follows is part of a technical feature that precedes it.

[0033] Unless otherwise specified, the terms “fixed connection” or “relatively fixed” in the claims and description shall be interpreted broadly to mean any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, fixed connection by fasteners, integral connection, direct fixed connection or indirect fixed connection.

[0034] Unless otherwise specified, in the claims and description, the terms “upper,” “lower,” “front,” “rear,” “left,” “right,” etc., indicate directions or positional relationships based on the directions explicitly shown in the drawings.

[0035] Unless otherwise specified in the claims and description, the terms "vertical direction," "front-back direction," and "left-right direction" essentially refer to the fact that these directions are relatively perpendicular to each other; that is, the vertical direction is perpendicular to the front-back direction, the vertical direction is perpendicular to the left-right direction, and the front-back direction is perpendicular to the left-right direction. In this embodiment, "upper" refers to the direction the ground faces when the sole is in contact with the ground, and vice versa. When the top abutment 3221 is directly facing the ground, the vertical direction is parallel to the axial direction of the deformable part 321. The following embodiments are described with the vertical direction parallel to the axial direction of the deformable part 321.

[0036] Unless otherwise specified in the claims and description, the terms "top abutment portion 3221 exposed on outsole 100" and "top abutment portion 3221 not exposed on outsole 100" should take into account whether the outsole 100 around the top abutment portion 3221 is flat. The function of the top abutment portion 3221 in this application is to abut against the ground to improve the grip of the sole. Therefore, "exposed on outsole 100" and "not exposed on outsole 100" should essentially be judged based on whether the top abutment portion 3221 can abut against the ground. When the top abutment portion 3221 is exposed on outsole 100, it is suitable for directly contacting the ground to generate action and reaction forces, thereby improving grip. When the top abutment portion 3221 is not exposed on outsole 100, no action or reaction forces are generated between the top abutment portion 3221 and the ground.

[0037] Unless otherwise specified in the claims and description, the term "hollow structure" means that the structure of a component itself is hollow, without limiting whether its interior is filled with material.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example See Figure 1 , Figure 1 The sole of the shoe in this embodiment is shown, such as Figure 3 As shown, Figure 3This is one of the structural diagrams of the transmission structure 330 and the anti-slip unit 320 in this embodiment. The sole is provided with an insole 200, a midsole 300 and an outsole 100, with the midsole 300 located between the insole 200 and the outsole 100.

[0040] like Figure 3 As shown, the outsole 100 has through holes 120 and several anti-slip protrusions 110. The through holes 120 allow the top abutment portion 3221 (described later) to pass through and protrude from the outsole 100. The number of through holes 120 corresponds to the number of anti-slip units 320 (described later). The anti-slip protrusions 110 are spaced apart on the outsole 100 and protrude towards the ground. The outsole 100 can be made of rubber material.

[0041] like Figure 3 As shown, the insole 200 is located on the side of the midsole 300 facing away from the ground, i.e., above the midsole 300, and is suitable for shielding the body 310 and the transmission structure 330 described later. In this embodiment, the insole 200 and the midsole 300 are made of different materials. In other embodiments, the insole 200 may be made of the same material as the midsole 300. In other embodiments, the insole 200 may be omitted, and the top of the midsole 300 may be slightly thickened to cover the transmission structure 330 and the anti-slip unit 320.

[0042] like Figure 2 and 3 As shown, Figure 2This is a perspective view of the anti-slip unit 320 and the transmission structure 330 in this embodiment. The midsole 300, located on the side of the outsole 100 facing away from the ground, includes a body 310, the anti-slip unit 320, and the transmission structure 330. The body 310 is the main filling material within the midsole 300, providing cushioning performance. The transmission structure 330 and the anti-slip unit 320 are both embedded within the body 310. The anti-slip unit 320 includes a deformation portion 321 and a displacement portion 322. The deformation portion 321 is annular and located above the through hole 120, suitable for contacting the ground or the outsole 100. In this embodiment, the lower end of the deformation portion 321 abuts against the outsole 100 around the through hole 120. The deformation portion 321 also extends axially on the side facing away from the ground and converges radially inward. The displacement part 322 is located inside the deformation part 321, and its upper end is connected to the upper end of the deformation part 321. The connection between the displacement part 322 and the deformation part 321 forms a force-bearing part 323. In this embodiment, the displacement part 322 has a conical hollow structure and extends along the axial direction of the deformation part 321. Its cone apex faces the ground, and its end facing the ground, i.e., the cone apex, is provided with a top abutting part 3221 suitable for abutting the ground. The angle between the cone surface of the displacement part 322 and the axial direction of the deformation part 321 is smaller than the angle between the deformation part 321 and the axial direction of the deformation part 321. The side cross-sectional view of the anti-slip unit 320 is approximately an "M" shape. When the deformation part 321 is not deformed, the top abutting part 3221 is located between the end and the bottom of the anti-slip protrusion 110 along the axial direction of the deformation part 321. The thickness of the deformable portion 321 is less than the thickness of the displacement portion 322, so that the deformable portion 321 can deform easily, and the displacement portion 322 is not easily deformed when the abutting portion 3221 abuts the ground. The transmission structure 330 is located on the side of the anti-slip unit 320 away from the ground. It is provided with an expansion portion 331, a first cone portion 332 and a second cone portion 333. The expansion portion 331 is annular, and its lower end is connected to the force-bearing portion 323. It also extends along the axial direction of the deformable portion 321 away from the ground and expands radially outward along the deformable portion 321. The angle between the expansion portion 331 and the axial direction of the deformable portion 321 is less than the angle between the axial direction of the deformable portion 321 and the axial direction of the deformable portion 321. Both the first cone portion 332 and the second cone portion 333 extend axially along the deformation portion 321 and are hollow structures. The cone apexes of the first cone portion 332 and the second cone portion 333 are opposite to each other along the axial direction of the deformation portion 321 and connected to each other. The cone bottom of the first cone portion 332 is connected to the force-bearing portion 323 and surrounds the displacement portion 322 to form an accommodating space 334. The expansion portion 331 surrounds the first cone portion 332 and the second cone portion 333, and its two ends (i.e., the upper and lower ends) along the axial direction of the deformation portion 321 are respectively connected to the cone bottoms of the first cone portion 332 and the second cone portion 333. The cone bottom of the second cone portion 333 and the upper end of the expansion portion 331 also abut against the inner bottom 200. In this embodiment, the body 310 fills the accommodating space 334, the interior of the second cone portion 333, and the gap formed by the surrounding portion and the first cone portion 332 and the second cone portion 333.

[0043] In terms of manufacturing, the sole in this embodiment is formed using FDM 3D printing. The outsole 100 uses rubber material, while the body 310, anti-slip unit 320, and transmission structure 330 all use elastic materials, but with different emphases. The body 310 uses a relatively soft elastic material to provide cushioning, while the transmission structure 330 uses a highly elastic material with greater elasticity than the body 310 to ensure force transmission. The anti-slip unit 320, because the deformation part 321 needs elastic deformation and the abutment part 3221 needs to abut the ground to provide grip, uses a highly tough elastic material to reduce the occurrence of breakage. The elasticity of the deformation part 321 material can also be greater than that of the outsole 100 material. Given the material selection emphasis disclosed in this application, those skilled in the art can choose the specific materials to use according to the actual situation. For example, lattice materials can be used, and different physical properties can be exhibited by controlling the density of the lattice material.

[0044] In this embodiment, the anti-slip action process of the shoe sole is as follows: like Figure 3 As shown, when the sole is not under stress, the deformation part 321 does not deform, and the top abutment part 3221 is located between the end and the bottom of the anti-slip protrusion 110 along the axial direction of the deformation part 321.

[0045] When the wearer walks normally, the force applied to the sole of the shoe is small, and the force transmitted to the force-bearing part 323 is also small. It is less than the first force that can push out the top part 3221, and cannot push the displacement part 322 to move so that the top part 3221 is exposed on the outsole 100 to press against the ground. In this case, the wearer will not feel any obvious discomfort.

[0046] like Figure 4 As shown, when the wearer exercises, the force generated by their legs far exceeds that of normal walking. This force includes at least a downward component (i.e., a component along the axial direction of the deformation portion 321 towards the ground). After the insole 200 is subjected to force, because the insole 200 abuts against the transmission structure 330, the force can be transmitted to the force-bearing portion 323 through the transmission structure 330. When the displacement portion 322 is subjected to the first force, it is adapted to move along the axial direction of the deformation portion 321 towards the ground so that the top abutment portion 3221 is exposed on the outsole 100 and the deformation portion 321 is elastically deformed. Therefore, the top abutment portion 3221 can abut against the ground to provide grip. Furthermore, the greater the force of the wearer's stomping, the greater the force of the top abutment portion 3221 against the ground, and the greater the grip provided.

[0047] After the force applied to the inner bottom 200 decreases or disappears, the deformation part 321 is also adapted to restore its deformation and drive the displacement part 322 to move away from the ground along the axial direction of the deformation part 321 and prevent the top part 3221 from being exposed on the outer bottom 100.

[0048] The first force can be matched with the axial displacement stroke of the displacement part 322 by adjusting the axial length, radial dimension, thickness, material, etc. of the deformation part 321 and / or the transmission structure 330. Those skilled in the art can make their own adjustments based on all the structures disclosed in this application, without any inventive effort.

[0049] This embodiment also provides a shoe, which includes an upper and a sole as described in this embodiment, with the upper fixed to the sole.

[0050] In this embodiment, the outsole 100 is provided with a through hole 120, and the anti-slip unit 320 is provided with a deformation part 321 and a displacement part 322. The deformation part 321 is annular and located at the through hole 120. It also extends along its axial direction away from the ground and converges radially inward. The displacement part 322 is located inside the deformation part 321. Its end facing the ground is provided with a top abutting part 3221 suitable for abutting the ground. Therefore, when the displacement part 322 is subjected to a first force including the component force along the axial direction of the deformation part 321 towards the ground, the displacement part 322 will be pushed to move along the axial direction of the deformation part 321 towards the ground, so that the top abutting part 3221 can pass through the opening formed by the annular deformation part 321 and be exposed on the outsole 100, thereby abutting the ground to provide grip. Furthermore, during this process, since the displacement part 322 is connected to the deformation part 321, and the deformation part 321 abuts against the ground or the outsole 100, the position of the deformation part 321 connected to the displacement part 322 will be driven by the displacement part 322, causing the deformation part 321 to undergo elastic deformation and thus store energy. Therefore, the deformation part 321 can also recover its elastic deformation and release energy, thereby driving the displacement part 322 to move along the axial direction of the deformation part 321 away from the ground and preventing the top abutment part 3221 from protruding from the outsole 100. By adjusting the elasticity of the deformation part 321 (for example, by selecting different materials, which is well known to those skilled in the art), the force applied to the displacement part 322 by the wearer during normal walking is less than the first force. In this case, the deformation part 321 deforms, but the top abutment part 3221 cannot protrude from the outsole 100 and thus cannot abut against the ground. Therefore, the wearer will not feel any obvious abnormality during normal walking. When the wearer exerts force during movement, this force far exceeds that of normal walking. The force applied to the displacement part 322 is greater than or equal to the first force, which pushes the top abutment part 3221 out of the outsole 100 to abut against the ground and provide grip. The greater the force applied by the wearer, the greater the force exerted by the top abutment part 3221 on the ground, and the stronger the grip. Therefore, the wearer can provide higher grip when stepping on the ground than during normal walking. When the force applied to the displacement part 322 is less than the first force, the deformation part 321 can recover its deformation and drive the top abutment part 3221 so that the top abutment part 3221 does not protrude from the outsole 100.

[0051] In this embodiment, the displacement part 322 is conical and extends axially along the deformation part 321. Its cone apex faces the ground and forms a top abutment part 3221. The cone apex structure is more conducive to providing grip when abutting the ground, while the conical shape itself has high structural stability and can avoid deformation when abutting the ground to a certain extent. The angle between the conical surface of the displacement part 322 and the axial direction of the deformation part 321 is smaller than the angle between the deformation part 321 and its axial direction. This makes it easier for the deformation part 321 to deform than the displacement part 322 when the force-bearing part 323 is subjected to force, which is beneficial for moving the displacement part 322. At the same time, it helps to prevent the displacement part 322 from deforming and affecting the grip performance of the top abutment part 3221 when it abuts the ground.

[0052] In this embodiment, a force-receiving part 323 is formed at the connection between the displacement part 322 and the deformation part 321. Applying force to this part can push the displacement part 322 to move. The force-receiving part 323 is located at the position furthest from the outer sole 100 in the anti-slip unit 320, which makes it easy to apply force to it. The midsole 300 includes a body 310, a transmission structure 330, and an anti-slip unit 320. The transmission structure 330 and the anti-slip unit 320 are embedded within the body 310. The transmission structure 330 is located on the side of the anti-slip unit 320 away from the ground and has an annular expansion portion 331. The expansion portion 331 is connected to the force-bearing portion 323 and extends axially along the deformation portion 321 away from the ground and expands radially outward along the deformation portion 321. Therefore, when it is necessary to thicken the midsole 300 to improve cushioning performance, compared to the solution of directly increasing the anti-slip unit 320 to thicken the midsole 300 without setting the transmission structure 330 (this solution will cause the displacement portion 322 to increase due to the increase of the anti-slip unit 320, making the top abutment portion 3221 more effective at abutting the ground), the transmission structure 330 is more effective in improving the cushioning performance of the midsole 300. When the shoe touches the ground, the displacement part 322 is prone to deformation, which is not conducive to the top part 3221 pressing against the ground to provide grip. Alternatively, there is a solution that does not set the transmission structure 330 and directly thickens the midsole 300 without changing the size of the anti-slip unit 320 (in this solution, the human body's stepping force is difficult to be effectively transmitted to the force receiving part 323, thus making it difficult to move the displacement part 322). In this embodiment, the sole can thicken the midsole 300 without changing the size of the anti-slip unit 320, and the transmission structure 330 is embedded in the body 310. Therefore, when the body 310 is subjected to stepping force on the side facing the ground, the body 310 will squeeze the expansion part 331, so that the force can be accurately transmitted to the force receiving part 323 without being excessively lost due to shock absorption by the body 310. Furthermore, since the expansion part 331 is annular and the body 310 is embedded inside and outside it, it will not have too much impact on the wearer's foot feel. Furthermore, since the force applied when the human body steps on the midsole 300 does not always correspond to the force-bearing part 323, but since the expansion part 331 is approximately a funnel structure, even if the applied force does not correspond to the force-bearing part 323 but corresponds to the expansion part 331, it can still be effectively transmitted to the force-bearing part 323 so as to drive the displacement part 322 to move.

[0053] In this embodiment, by making the elasticity of the material of the transmission structure 330 greater than that of the material of the body 310, the midsole 300 can maintain its soft and shock-absorbing performance to a certain extent, while the applied force can be effectively transmitted to the force-receiving part 323 so as to push the displacement part 322 to move.

[0054] In this embodiment, the angle between the expansion portion 331 and the deformation portion 321 along the axis is smaller than the angle between the deformation portion 321 and the deformation portion 321 along the axis. This is beneficial because when the midsole 300 is subjected to force, the deformation portion 321 deforms preferentially, reducing the possibility that the expansion portion 331 will continue to expand outward under the action of force, which would make it difficult for the force to be effectively transmitted to the force-bearing portion 323.

[0055] In this embodiment, the transmission structure 330 is further provided with a first cone 332 and a second cone 333 extending axially along the deformation portion 321. The first cone 332 and the second cone 333 are opposite to and connected to each other along the axial direction of the deformation portion 321. The bottom of the first cone 332 is connected to the force-bearing portion 323. The expansion portion 331 surrounds the first cone 332 and the second cone 333, and its two ends along the axial direction of the deformation portion 321 are respectively connected to the bottom of the first cone 332 and the second cone 333. Therefore, the force applied to the middle base 300 can be transmitted not only through the expansion portion 331, but also through the first cone 332 and the second cone 333 to the force-bearing portion 323. Furthermore, since the first cone 332 and the second cone 333 are also connected to the expansion portion 331, it is beneficial to reduce the situation where the expansion portion 331 continues to expand outward when subjected to force, thereby causing the force to be dispersed.

[0056] In this embodiment, both the first cone portion 332 and the displacement portion 322 are hollow structures. The cone bottoms of the first cone portion 332 and the displacement portion 322 enclose each other to form an accommodating space 334. Therefore, the body 310 can be filled into the accommodating space 334 to provide a certain buffer when the top part 3221 hits the ground, so as to avoid excessive foot discomfort.

[0057] In this embodiment, by adding an insole 200, which is located on the side of the midsole 300 away from the ground and covers the body 310 and the transmission structure 330, and the second cone 333 is a hollow structure, the insole 200 abuts against the second cone 333 and the expansion portion 331, so the body 310 can be filled into the second cone 333, and the human foot will not directly contact the transmission structure 330, which helps to reduce the wearer's sense of discomfort.

[0058] In this embodiment, the outsole 100 is also provided with a plurality of anti-slip protrusions 110, which can provide a certain grip even when the top abutment portion 3221 is not exposed on the outsole 100. When the deformable portion 321 is not deformed, the top abutment portion 3221 is located between the end and the bottom of the anti-slip protrusion 110 along the axial direction of the deformable portion 321, so that the top abutment portion 3221 only needs to move a small distance to expose the outsole 100 to abut against the ground.

[0059] 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.
