Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe structure, and in particular to a cushioning-optimized sports shoe sole. Background Technology
[0002] The sole is a crucial component of athletic shoes, located at the bottom and in direct contact with the ground. Its design and material selection play a key role in the functionality and comfort of athletic shoes, especially considering the needs of different sports such as running, basketball, and soccer. The athletic shoe sole is one of the core components of footwear engineering, with its main functions including cushioning, traction, flexibility, and support. Common materials used in athletic shoe soles include EVA, rubber, and TPU.
[0003] In the field of sports science, the design of athletic shoe soles directly impacts athletes' performance and safety: athletic shoe soles absorb impact, reducing the risk of injury to joints (such as the knees and ankles), especially in high-intensity sports (such as running and basketball); some high-end athletic shoe soles use special materials to achieve energy return, helping athletes move more efficiently; and the design of athletic shoe soles is adjusted according to different sports (such as running, basketball, and tennis) and playing surfaces (such as hard courts, grass, and mud). For example, basketball shoe soles typically have deeper treads to provide better grip, while running shoe soles focus more on lightweight design and cushioning.
[0004] Currently, shoe soles are designed with multiple layers, each with different softness and hardness characteristics. However, this results in a lack of firmness during footsteps, especially in the forefoot and heel areas where heavy pressure is applied. Utility Model Content
[0005] The main purpose of this invention is to provide a cushioning-optimized sports shoe sole, which aims to solve the problem that multi-layered sole structures cannot provide comprehensive cushioning and support in the forefoot and heel areas.
[0006] To achieve the above objectives, this utility model provides a cushioning-optimized athletic shoe sole, comprising:
[0007] insole;
[0008] The midsole is disposed on the lower surface of the insole. The midsole includes an upper midsole, a middle midsole, and a lower midsole, which are stacked in order of increasing hardness. The middle midsole has a first front through hole and a first rear through hole at the forefoot position and the heel position, respectively. The lower midsole has a second front through hole and a second rear through hole corresponding to the first front through hole and the first rear through hole, respectively. The second front through hole is surrounded by the first front through hole in a plane, and the second rear through hole is surrounded by the first rear through hole in a plane.
[0009] The front support includes a rigid upper front piece, a rigid middle front piece, and a soft lower front piece stacked sequentially from top to bottom. The upper front piece is disposed on the lower surface of the upper layer of the midsole. The upper front piece surrounds the first front through hole in a plane. The middle front piece and the lower front piece fill the first front through hole and the second front through hole, respectively.
[0010] The rear support includes a rigid upper rear sheet, a rigid middle rear sheet, and a soft lower rear sheet stacked sequentially from top to bottom. The upper rear sheet is disposed on the lower surface of the upper layer of the midsole. The upper rear sheet surrounds the first rear through hole in a plane. The middle rear sheet and the lower rear sheet fill the first rear through hole and the second rear through hole, respectively.
[0011] Outsole, located on the lower surface of the insole.
[0012] Furthermore, the materials of the front upper piece, the front middle piece, the rear upper piece, and the rear middle piece are the same as those of the lower insole layer, and the materials of the front lower piece and the rear lower piece are the same as those of the upper insole layer.
[0013] Furthermore, the front middle piece and the rear middle piece are connected to the middle layer of the insole, and the front lower piece and the rear lower piece are connected to the lower layer of the insole.
[0014] Furthermore, the front support is a connecting structure in the thickness direction, and the rear support is a connecting structure in the thickness direction.
[0015] Furthermore, the front upper piece and the rear upper piece are connected to the lower surface of the upper layer of the midsole.
[0016] Furthermore, the front middle piece and the front lower piece are connected to each other in the thickness direction, and the rear middle piece and the rear lower piece are connected to each other in the thickness direction.
[0017] Furthermore, the front upper piece, the front middle piece, and the front lower piece are all circular pieces, as are the rear upper piece, the rear middle piece, and the rear lower piece.
[0018] Furthermore, the diameter of the first front through hole is 1.5 to 2.0 times the diameter of the second front through hole, and the diameter of the first rear through hole is 1.5 to 2.0 times the diameter of the second rear through hole.
[0019] Furthermore, the front support and the rear support are connected to the midsole.
[0020] Furthermore, the midsole, the front support, and the rear support are made of the same type of material.
[0021] The cushioning-optimized sports shoe sole provided by this utility model includes a midsole comprising an upper midsole, a middle midsole, and a lower midsole, all with increasing hardness in a stacked manner. The forefoot support comprises a hard upper forefoot piece, a hard middle forefoot piece, and a soft lower forefoot piece stacked from top to bottom. When the forefoot support is compressed, the upper forefoot piece provides relatively hard cushioning based on the middle midsole, the middle forefoot piece provides even harder cushioning based on the lower midsole, and the lower forefoot piece is soft, avoiding a rigid connection with the outsole. When subjected to greater pressure, the lower forefoot piece is compressed, thus creating the hardest cushioning effect, ultimately providing a multi-layered cushioning effect. The rear support also provides different cushioning effects in layers. Attached Figure Description

[0033] Reference Figures 1 to 7 In one embodiment of this utility model, a cushioning-optimized sports shoe sole includes:
[0034] Insole 100;
[0035] The midsole 200 is disposed on the lower surface of the insole 100. The midsole 200 includes an upper midsole layer 210, a middle midsole layer 220, and a lower midsole layer 230, which are stacked in order of increasing hardness. The middle midsole layer 220 is provided with a first front through hole 221 and a first rear through hole 222 at the forefoot and heel positions, respectively. The lower midsole layer 230 is provided with a second front through hole 231 and a second rear through hole 232 corresponding to the first front through hole 221 and the first rear through hole 222, respectively. The second front through hole 231 is surrounded by the first front through hole 221 in a plane, and the second rear through hole 232 is surrounded by the first rear through hole 222 in a plane.
[0036] The front support 300 includes a rigid upper front piece 310, a rigid middle front piece 320, and a soft lower front piece 330 stacked from top to bottom. The upper front piece 310 is disposed on the lower surface of the upper layer 210 of the midsole. The upper front piece 310 surrounds the first front through hole 221 in a plane. The middle front piece 320 and the lower front piece 330 fill the first front through hole 221 and the second front through hole 231, respectively.
[0037] The rear support 400 includes a rigid upper rear sheet 410, a rigid middle rear sheet 420, and a soft lower rear sheet 430 stacked from top to bottom. The upper rear sheet 410 is disposed on the lower surface of the upper layer 210 of the midsole. The upper rear sheet 410 surrounds the first rear through hole 222 in a plane. The middle rear sheet 420 and the lower rear sheet 430 fill the first rear through hole 222 and the second rear through hole 232, respectively.
[0038] Outsole 500 is disposed on the lower surface of the insole 200.
[0039] In existing technology, shoe soles are designed with multiple layers, each with different softness and hardness characteristics; however, this results in a lack of hardness during footsteps, especially in the forefoot and heel areas where the force is greater.
[0040] This utility model provides a cushioned and optimized sports shoe sole, comprising an insole 100, a midsole 200, an outsole 500, a forefoot support 300, and a rearfoot support 400. EVA soles are widely used midsole materials in sports shoes, casual shoes, and other fields. They are lightweight and soft, possessing rubber-like elasticity, and maintain flexibility even below 0°C, making them suitable for cold environments. They have high chemical stability, are ozone-resistant, anti-aging, and non-toxic and environmentally friendly. Higher vinyl acetate content results in better elasticity and transparency, but reduces abrasion resistance and rigidity; an increased melt index improves processability but decreases strength.
[0041] The insole 100 is the padding layer inside the shoe that comes into direct contact with the sole of the foot. Its main function is to provide extra comfort and support while absorbing impact.
[0042] The 200 midsole, located between the insole and outsole, is the core part of the shoe. Its main function is to provide cushioning and support, reducing the impact of ground reaction forces on the feet.
[0043] The midsole 200 is located on the lower surface of the insole 100. The midsole 200 and the insole 100 can be connected in various suitable ways. The midsole 200 comprises an upper midsole layer 210, a middle midsole layer 220, and a lower midsole layer 230, which are stacked in order of increasing hardness. The upper midsole layer 210 provides the softest cushioning, the middle midsole layer 220 provides moderate cushioning, and the lower midsole layer 230 provides support. The upper midsole layer 210, the middle midsole layer 220, and the lower midsole layer 230 can be made of the same material, and their hardness can be adjusted by modifying the formula or process.
[0044] The midsole middle layer 220 has a first front through-hole 221 and a first rear through-hole 222 at the forefoot and heel positions, respectively. The midsole lower layer 230 has a second front through-hole 231 and a second rear through-hole 232 corresponding to the first front through-hole 221 and the first rear through-hole 222, respectively. The second front through-hole 231 is surrounded by the first front through-hole 221 in a plane. The second rear through-hole 232 is surrounded by the first rear through-hole 222 in a plane.
[0045] The front support 300 includes a rigid upper front piece 310, a rigid middle front piece 320, and a soft lower front piece 330 stacked sequentially from top to bottom. The upper front piece 310 is disposed on the lower surface of the upper layer 210 of the midsole. The upper front piece 310 surrounds the first front through hole 221 in the plane. The middle front piece 320 and the lower front piece 330 fill the first front through hole 221 and the second front through hole 231, respectively.
[0046] The forefoot support 300, located at the forefoot, provides cushioning. The upper forefoot piece 310, not covered by the midfoot piece 320, contacts the midsole layer 220. When the forefoot support 300 is compressed, the upper forefoot piece 310 provides cushioning based on the midsole layer 220. This cushioning effect is firmer than that provided by the upper midsole layer 210. Although the upper forefoot piece 310 is firm, the upper midsole layer 210 provides cushioning, preventing discomfort. The midfoot piece 320, not covered by the lower forefoot piece 330, contacts the lower midsole layer 230. When the forefoot support 300 is compressed, the midfoot piece 320 provides cushioning based on the lower midsole layer 230. This cushioning effect is even firmer. The lower forefoot piece 330 is soft, avoiding a rigid connection with the outsole 500. When subjected to heavy pressure, the lower forefoot piece 330 is compressed, resulting in the firmest cushioning effect. By connecting the front support 300 to the midsole middle layer 220, the lower midsole layer 230, and the outsole 500, different cushioning effects can be provided in layers.
[0047] The rear support 400 includes a rigid upper rear sheet 410, a rigid middle rear sheet 420, and a soft lower rear sheet 430 stacked sequentially from top to bottom. The upper rear sheet 410 is disposed on the lower surface of the upper layer 210 of the midsole, and surrounds the first rear through hole 222 in a plane. The middle rear sheet 420 and the lower rear sheet 430 fill the first rear through hole 222 and the second rear through hole 232, respectively. The function of the rear support 400 is the same as that of the front support 300, and will not be described in detail.
[0048] The outsole 500 is the part of the shoe that contacts the ground. It is usually made of abrasion-resistant material and its main function is to provide grip and abrasion resistance, ensuring the stability and durability of the shoe on various surfaces. The outsole 500 is located on the lower surface of the midsole 200.
[0049] In summary, the midsole 200 comprises an upper midsole 210, a middle midsole 220, and a lower midsole 230, all with increasing hardness. The front support 300 comprises a rigid upper front piece 310, a rigid middle front piece 320, and a soft lower front piece 330, stacked from top to bottom. When the front support 300 is compressed, the upper front piece 310 provides relatively firm cushioning based on the middle midsole 220, the middle front piece 320 provides even firmer cushioning based on the lower midsole 230, and the lower front piece 330 is soft, avoiding a rigid connection with the outsole 500. When subjected to greater pressure, the lower front piece 330 is compressed, resulting in the firmest cushioning effect, ultimately providing a multi-layered cushioning effect. The rear support 400 also provides different cushioning effects through layering.
[0050] In one embodiment, the front upper piece 310, the front middle piece 320, the rear upper piece 410, and the rear middle piece 420 are made of the same material as the lower midsole layer 230, and the front lower piece 330 and the rear lower piece 430 are made of the same material as the upper midsole layer 210.
[0051] In this embodiment, considering that the front upper piece 310, front middle piece 320, rear upper piece 410 and rear middle piece 420 require relatively hard materials, while the front lower piece 330 and rear lower piece 430 require relatively soft materials, and the hardness of the midsole upper layer 210, midsole middle layer 220 and midsole lower layer 230 increases in sequence, the above material correspondence is formed, which reduces the processing difficulty and improves the compatibility between the interfaces.
[0052] In one embodiment, the front center piece 320 and the rear center piece 420 are connected to the midsole middle layer 220, and the front lower piece 330 and the rear lower piece 430 are connected to the midsole lower layer 230.
[0053] In this embodiment, the front center piece 320 and the rear center piece 420 are connected to the midsole middle layer 220, and the front bottom piece 330 and the rear bottom piece 430 are connected to the midsole lower layer 230, thereby preventing abnormal displacement of the front center piece 320, the rear center piece 420, the front bottom piece 330, and the rear bottom piece 430 during use. The specific connection method can be sewing or bonding, etc.
[0054] In one embodiment, the front support 300 is a connecting structure in the thickness direction, and the rear support 400 is a connecting structure in the thickness direction.
[0055] In this embodiment, during installation, the front support 300, as a single structure, can be easily installed into place, and similarly, the rear support 400, as a single structure, can be easily installed into place. Taking the front support 300 as an example, the connection method between the front upper piece 310, the front middle piece 320, and the front lower piece 330 can be adhesive bonding or other methods.
[0056] In one embodiment, the front upper piece 310 and the rear upper piece 410 are connected to the lower surface of the midsole upper layer 210.
[0057] In this embodiment, both the front upper piece 310 and the rear upper piece 410 are connected to the lower surface of the upper layer 210 of the midsole, thus simplifying the process of setting up the front support 300 and the rear support 400. The connection method between the front upper piece 310 and the rear upper piece 410 on the upper layer 210 of the midsole can be sewing or bonding, etc.
[0058] In one embodiment, the front middle piece 320 and the front lower piece 330 are connected to each other in the thickness direction, and the rear middle piece 420 and the rear lower piece 430 are connected to each other in the thickness direction.
[0059] In this embodiment, the front middle piece 320 and the front lower piece 330 are connected, and the rear middle piece 420 and the rear lower piece 430 are connected. In addition, the front upper piece 310 and the rear upper piece 410 are set independently, thereby optimizing the setting process of the front support 300 and the rear support 400.
[0060] In one embodiment, the front upper piece 310, the front middle piece 320, and the front lower piece 330 are all circular pieces, and the rear upper piece 410, the rear middle piece 420, and the rear lower piece 430 are all circular pieces.
[0061] In this embodiment, the front upper piece 310, front middle piece 320, front lower piece 330, rear upper piece 410, rear middle piece 420, and rear lower piece 430 are all set as circular pieces, thereby reducing the difficulty of processing. The specific diameter of each structure is selected and designed according to the actual situation.
[0062] In one embodiment, the diameter of the first front through hole 221 is 1.5 to 2.0 times the diameter of the second front through hole 231, and the diameter of the first rear through hole 222 is 1.5 to 2.0 times the diameter of the second rear through hole 232.
[0063] In this embodiment, if the diameters of the first front through hole 221 and the first rear through hole 222 are too small, the contact area between the front middle piece 320 and the rear middle piece 420 and the bottom layer 230 will be too small, thus failing to achieve a buffering effect through the front middle piece 320 and the rear middle piece 420.
[0064] In one embodiment, the front support 300 and the rear support 400 are connected to the midsole 200.
[0065] In this embodiment, the front support 300 and the rear support 400 are connected to the midsole 200 to form a whole, thereby reducing the difficulty of the entire cushioning optimization process of the sports shoe sole.
[0066] In one embodiment, the midsole 200, the front support 300, and the rear support 400 are made of the same type of material.
[0067] In this embodiment, different combinations or different processing techniques are applied to the same type of material to achieve differences in hardness at various locations.
[0068] In summary, the cushioning-optimized sports shoe sole provided by this utility model includes a midsole 200 comprising an upper midsole 210, a middle midsole 220, and a lower midsole 230, all with increasing hardness in a stacked manner. The forefoot support 300 comprises a rigid upper forefoot piece 310, a rigid middle forefoot piece 320, and a soft lower forefoot piece 330, stacked from top to bottom. When the forefoot support 300 is compressed, the upper forefoot piece 310 provides relatively firm cushioning based on the middle midsole piece 220, the middle forefoot piece 320 provides even firmer cushioning based on the lower midsole piece 230, and the lower forefoot piece 330 is soft, avoiding a rigid connection with the outsole 500. When subjected to greater pressure, the lower forefoot piece 330 is compressed, thus forming the firmest cushioning effect, ultimately providing a multi-layered cushioning effect. The rear support 400 also provides different cushioning effects in layers.
[0069] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
