[0055] Due to their aesthetic and lightweight requirements, casual shoes generally have thin soles. However, with thin soles, users may experience foot pain and discomfort after prolonged walking. To address this issue, this application provides a shock-absorbing sole 100 (… Figure 2 (as shown) and shoes 1000 ( Figure 1 (As shown). In the embodiments of this application, the shape of the forefoot portion of the sole includes, but is not limited to, round toe, square toe (as shown). Figure 5 (as shown) and pointed (as shown) Figure 2 (As shown).
[0056] Please see Figure 1 The shoe 1000 of this embodiment includes a shock-absorbing sole 100 and an upper 300. The shock-absorbing sole 100 is connected to the upper 300, and the shock-absorbing sole 100 and the upper 300 together form an inner shoe space 500. When the user wears the shoe, the user's foot extends into the inner shoe space 500.
[0057] Please see Figures 5 to 7 The shock-absorbing sole 100 of this application includes a sole 10 and a shock-absorbing structure 30. The thickness H1 of the forefoot region 113 of the sole 10 ranges from 3.5 mm to 44 mm, and the thickness H2 of the heel region 115 of the sole 10 ranges from 10 mm to 40 mm. The shock-absorbing structure 30 is connected to the sole 10 and is disposed in a designated area or the entire sole region 11 of the sole 10. The designated area includes the forefoot region 113 and / or the heel region 115 of the sole 10. The shock-absorbing structure 30 includes a deformable shock-absorbing element 31, which contacts the insole. When the user's foot presses down on the insole, the pressure is transmitted to the shock-absorbing element 31 through the insole. The shock-absorbing element 31 deforms, reducing the reaction force of the shock-absorbing sole 100 on the user's foot, thereby achieving the purpose of shock absorption.
[0058] Specifically, because the sole 10 of casual shoes is thinner than that of athletic shoes, users inevitably experience foot pain and other problems when walking for extended periods in casual shoes, resulting in poor comfort. The shock-absorbing sole 100 of this application is applied to casual shoes. The shock-absorbing sole 100 serves to absorb shock and cushion the impact during walking, preventing foot pain and discomfort during prolonged walking and ensuring greater comfort for the user.
[0059] The sole 10 of this application is the outsole, located on the outermost layer of the bottom of the shoe 1000. The outsole is in direct contact with the ground and provides slip resistance and abrasion resistance. During walking, the outsole offers good slip resistance, making it less likely for the user to slip. The outsole is typically made of materials such as natural or synthetic rubber, resulting in good abrasion resistance and a longer overall lifespan for the shoe 1000.
[0060] Please see Figure 6In this application, the thickness H1 of the forefoot area 113 of the sole 10 ranges from 3.5mm to 44mm, and the thickness H2 of the heel area 115 ranges from 10mm to 40mm. At this thickness, the overall thickness of the sole 10 is relatively thin, making it suitable for casual shoes, resulting in lighter and more aesthetically pleasing shoes. However, if the thickness H1 of the forefoot area 113 is less than 3.5mm, and / or the thickness H2 of the heel area 115 is less than 10mm, the sole 10 is too thin. This leads to wear and tear, a shorter lifespan, and increased impact on the foot during walking, potentially causing pain or discomfort. When the thickness H1 of the forefoot region 113 of the sole 10 is greater than 44 mm, and / or the thickness H2 of the heel region 115 of the sole 10 is greater than 40 mm, the sole 10 is too thick and does not meet the requirements of lightweight and aesthetics for casual shoes. In the embodiment of this application, the thickness H1 of the forefoot region 113 of the sole 10 is 7.0 mm.
[0061] For example, the thickness H1 of the forefoot region 113 of the sole 10 can be 3.5mm, 5.3mm, 7.0mm, 8.3mm, 9.6mm, 10.1mm, 11.4mm, 13.6mm, 15.2mm, 18.0mm, 21.4mm, 24.7mm, 28.7mm, 30.5mm, 32.6mm, 36.1mm, 37.4mm, 41.2mm, 42.3mm, or 44.0mm, etc. In this embodiment, the thickness H1 of the forefoot region 113 of the sole 10 is 7.0mm.
[0062] Furthermore, the thickness H1 of the forefoot area 113 of the sole 10 can also be in the range of [3.5mm, 18.0mm]. In this case, the thickness of the forefoot area 113 of the sole 10 is relatively thin, thus the overall thickness of the sole 10 is relatively thin, and the shoe 1000 is relatively lightweight and aesthetically pleasing.
[0063] The thickness H2 of the heel region 115 of the sole 10 can be 10mm, 12mm, 16mm, 19mm, 21mm, 23mm, 25mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 38mm, or 40mm, etc. In this embodiment, the thickness H2 of the heel region 115 of the sole 10 is 12mm. Further, the thickness H2 of the heel region 115 of the sole 10 can also be in the range of [10.0mm, 30.0mm]. In this case, the thickness of the heel region 115 of the sole 10 is also relatively thin, resulting in a thinner overall sole 10, making the shoe 1000 lighter and more aesthetically pleasing.
[0064] Please see Figure 5 and Figure 7 The shock-absorbing structure 30 and the sole 10 can be an integral or separate structure. When the shock-absorbing structure 30 and the sole 10 are an integral structure, the shock-absorbing structure 30 can be integrally molded with the sole 10. When the shock-absorbing structure 30 and the sole 10 are separate structures, the shock-absorbing structure 30 can be detachably or non-detachably connected to the sole 10. When the shock-absorbing structure 30 and the sole 10 are separate structures, the sole 10 has an installation space 1155 for placing the shock-absorbing structure 30. The side of the shock-absorbing structure 30 near the installation space 1155 has several blind holes. The shock-absorbing structure 30 is connected to the sole 10 by compression. Air enters the blind holes during the compression process, causing the blind holes to expand and form shock-absorbing components 31. When the shock-absorbing structure 30 and the sole 10 are detachably connected, it facilitates the maintenance and replacement of the shock-absorbing structure 30.
[0065] The shock-absorbing structure 30 is connected to the side of the sole 10 facing the inner shoe space 500. The number of shock-absorbing elements 31 in the shock-absorbing structure 30 may be, but is not limited to, one or more. The shock-absorbing element 31 can deform under pressure and return to its initial state when the pressure is removed. During walking, when the user's foot applies pressure to the shock-absorbing structure 30, the shock-absorbing element 31 can withstand this pressure and undergo a certain degree of deformation, providing shock absorption and cushioning while maintaining softness, thus making the user's wear more comfortable. When the pressure applied by the user's foot to the shock-absorbing structure 30 is removed, the shock-absorbing element 31 can rebound, returning to its initial state, so that it can deform again under the next pressure. The shock-absorbing element 31 can absorb and disperse the force transmitted from the foot to the ground, and can also absorb and disperse the reaction force (impact force) transmitted from the ground to the foot, thereby reducing the impact force of the ground on the foot and reducing the risk of foot fatigue and injury.
[0066] Please see Figure 2 , Figure 3 , Figures 5 to 7 In one embodiment, the shock-absorbing structure 30 is disposed in a designated area of the shoe 1000. In this case, the shock-absorbing structure 30 uses less material, saving material costs, and the overall weight of the shock-absorbing sole 100 is lighter, making the shoe 1000 more lightweight and providing better comfort for the user. During walking, the shock-absorbing structure 30 can cushion and absorb shock in the designated area of the user's foot, preventing foot pain and discomfort.
[0067] Please see Figure 2 , Figures 5 to 7In one example, the shock-absorbing structure 30 is located in the heel area 115 of the sole 10. Because the heel area 115 of the foot exerts significant pressure on the heel area 115 of the sole 10 during walking, without the shock-absorbing structure 30, the reaction force from the ground to the heel area 115 of the foot is substantial after contact with the ground. This results in a greater impact force on the heel area 115, making it prone to pain and discomfort. When the heel area 115 of the sole 10 is provided with a shock-absorbing structure 30, when the heel area 115 of the foot applies pressure to the shock-absorbing structure 30, the shock absorber 31 can support the heel area 115 of the foot and produce a certain deformation, thereby reducing the impact force of the heel area 115 of the foot on the ground and the reaction force of the ground on the heel area 115 of the foot, which can avoid the user's foot pain and discomfort, and the user's wearing comfort is better.
[0068] Please see Figure 3 , Figures 5 to 7 In another example, the shock-absorbing structure 30 is located in the forefoot area 113 of the sole 10. Because the heel area 115 of the foot exerts significant pressure on the forefoot area 113 of the sole 10 during walking, without the shock-absorbing structure 30, the reaction force from the ground on the forefoot area 113 after contact with the ground is substantial. This results in a greater impact force on the forefoot area 113, making it prone to pain and discomfort. With the forefoot area 113 of the sole 10 located in the shock-absorbing structure 30, when the forefoot area 113 of the foot applies pressure to the shock-absorbing structure 30, the shock absorber 31 can support the forefoot area 113 of the foot and produce a certain deformation, thereby reducing the impact force of the forefoot area 113 of the foot on the ground and the reaction force of the ground on the forefoot area 113 of the foot, which can avoid the user's foot pain and discomfort, and the user's wearing comfort is better.
[0069] Please see Figure 4 , Figures 5 to 7In another embodiment, the shock-absorbing structure 30 is disposed in the full-length area 11 of the sole 10. The full-length area 11 of the sole 10 includes the heel area 115, the midfoot area 117, and the forefoot area 113. The midfoot area 117 connects the forefoot area 113 and the heel area 115. In this case, the heel area 115, midfoot area 117, and forefoot area 113 of the user's foot all correspond to the shock-absorbing structure 30. The shock-absorbing structure 30 can play a good role in shock absorption and cushioning. When the foot applies pressure to the shock-absorbing structure 30, the shock absorber 31 can support all parts of the foot and generate a certain deformation, thereby reducing the impact force of the foot on the ground and the reaction force of the ground on the foot, avoiding foot pain and discomfort, and improving the user's wearing comfort.
[0070] In the shock-absorbing sole 100 of this application embodiment, the shock-absorbing structure 30 is connected to the sole 10 and is disposed in a designated area or the entire sole area 11 of the sole 10. During the user's walking process, when the user's foot applies pressure to the shock-absorbing structure 30, the shock-absorbing component 31 can provide a certain support for the user's foot and can generate a certain deformation to absorb shock and cushion the impact. This reduces the impact force of the foot on the ground and the reaction force (impact force) of the ground on the foot, avoiding pain and discomfort in the user's feet, and providing better comfort for the user.
[0071] The following description, in conjunction with the attached diagram, further explains the shock-absorbing sole 100.
[0072] Please see Figure 7 and Figure 8 In some embodiments, the height H3 of the shock-absorbing structure 30 ranges from 2.5mm to 35.0mm. In this case, when the user's foot applies pressure to the shock-absorbing structure 30, the structure can withstand the pressure and deform to a certain extent. While maintaining softness, it can absorb and cushion the impact, thereby reducing the impact force on the foot. Users are less likely to experience foot pain or discomfort during walking, resulting in better comfort. When the height H3 of the shock-absorbing structure 30 is less than 2.5mm, the structure is too low, providing poor support and cushioning. Prolonged walking can easily lead to foot pain and discomfort. When the height H3 of the shock-absorbing structure 30 is greater than 35.0mm, the height is too high, resulting in an excessively thick shock-absorbing sole 100, which does not meet the requirements of lightweight and aesthetically pleasing casual shoes.
[0073] For example, the height H3 of the damping structure 30 can be 2.5mm, 4.0mm, 5.3mm, 6.5mm, 8.7mm, 9.2mm, 10.4mm, 11.3mm, 13.2mm, 14.7mm, 16.0mm, 19.8mm, 20.6mm, 21.2mm, 23.5mm, 24.9mm, 26.1mm, 28.2mm, 32.1mm, or 35.0mm, etc. In this embodiment, the height H3 of the damping structure 30 is 6.5mm. Further, the height H3 of the damping structure 30 can also be in the range of [4.0mm, 16.0mm]. At this time, the height H3 of the shock-absorbing structure 30 is relatively high, and the shock-absorbing structure 30 has a good effect on shock absorption and cushioning of the foot. Moreover, when the shock-absorbing structure 30 is installed on the sole 10, the overall thickness of the shock-absorbing sole 100 is not too thick, and the shock-absorbing sole 100 is relatively lightweight. As a result, the shoe 1000 is relatively lightweight and aesthetically pleasing.
[0074] Please see Figure 7 and Figure 8 In some embodiments, the shock-absorbing structure 30 includes a base 33 and a plurality of shock-absorbing elements 31 extending from the base 33 in a direction away from the sole 10, the base 33 being connected to the sole 10.
[0075] The base 33 connects to the side of the sole 10 facing the inner space 500, while the shock absorber 31 supports the user's foot and provides shock absorption and cushioning. When the user's foot applies pressure to the shock absorber 31, the shock absorber 31 provides support and deforms to reduce the impact force of the foot on the ground and the reaction force of the ground on the foot, thus preventing foot pain and discomfort and providing good comfort for the user.
[0076] In one embodiment, the base 33 and the shock absorber 31 can be an integral structure. In this case, the base 33 and the shock absorber 31 can be integrally molded, and the processing steps of the shock-absorbing structure 30 are relatively simple. For example, the base 33 and the shock absorber 31 can be integrally pressed, and a cavity with an opening facing the base 33 can be formed inside the shock absorber 31. In another embodiment, the base 33 and the shock absorber 31 can be separate structures. The shock absorber 31 can first be pressed to form a structure with an internal cavity and an open end, and then the open end of the shock absorber 31 can be installed on the base 33.
[0077] The number of shock-absorbing components 31 can be, but is not limited to, three, four, five, six, or more. Multiple shock-absorbing components 31 can be evenly distributed in a designated area or the entire sole area 11 of the sole 10. With such even distribution, the support provided by the multiple shock-absorbing components 31 to various parts of the foot is more uniform, and the shock absorption and cushioning effect is also more uniform. The material of the shock-absorbing components 31 includes, but is not limited to, rubber or thermoplastic polyurethane (TPU), allowing them to deform under pressure. When the shock-absorbing component 31 and the base 33 are an integral structure, the material of the shock-absorbing component 31 is the same as that of the base 33.
[0078] Please see Figure 5 , Figure 7 and Figure 9 Specifically, in some embodiments, the shock absorber 31 includes a plurality of protrusions 311 with internal cavities, and the shock absorber structure 30 together with the sole 10 forms a closed air cavity.
[0079] The shock absorber 31 is a protrusion 311 extending from the base 33 in a direction away from the sole 10. The cross-sectional shape of the shock absorber 31 can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes. The cross-sectional shape of the shock absorber 31 in this application is circular, that is, the shock absorber 31 is approximately a cylindrical structure with a hemispherical top. The shock absorber 31 has an internal cavity, and the base 33 has multiple through holes 331 that communicate with the cavity to form blind holes with openings facing the sole 10. External air can enter the blind holes through these openings. When the shock absorber structure 30 is installed on the sole 10, the shock absorber structure 30 can be connected to the sole 10 by compression. During the compression process, external air enters the blind holes through the openings, thereby allowing the protrusion 311 to expand and form the shock absorber 31. The shock absorber structure 30 and the sole 10 together enclose multiple blind holes into multiple closed air cavities. The air chamber is filled with air, and even when the damper 31 is compressed, the air in the air chamber will not flow out. Therefore, even when the damper 31 deforms under pressure, the presence of a certain amount of gas inside prevents it from over-deforming.
[0080] Despite large deformations, users will not experience a noticeable collapse when their feet exert force on the shock-absorbing structure 30 during walking. The shock-absorbing component 31 provides good support for the feet, resulting in stable walking. Furthermore, the shock-absorbing component 31 rebounds faster, making walking easier and preventing foot fatigue and pain.
[0081] Please see Figure 7 and Figure 9In some embodiments, the multiple through holes 331 on the base 33 correspond one-to-one with multiple cavities, and the through holes 331 communicate with the cavities. The cross-sectional area of the through holes 331 can be less than or equal to the cross-sectional area of the cavity. Before the shock-absorbing structure 30 is connected to the sole 10, external air can enter the corresponding cavity through the through holes 331. After the shock-absorbing structure 30 is connected to the sole 10, the side of the sole 10 facing the shoe interior space 500 can block the multiple through holes 331 on the base 33, so that the shock-absorbing structure 30 and the sole 10 together form multiple closed air cavities. At this time, the shock absorption and cushioning effect of the shock absorber 31 is better, the rebound speed of the shock absorber 31 is also faster, the user's wearing is more comfortable, and walking is easier. In this embodiment, the shock-absorbing structure 30 can be provided in the forefoot area 113 of the sole 10, the shock-absorbing structure 30 can also be provided in the heel area 115 of the sole 10, and the shock-absorbing structure 30 can also be provided in the forefoot area 113 of the sole 10.
[0082] Please see Figure 7 and Figure 10 In other embodiments, the multiple through holes 331 on the base 33 correspond one-to-one with multiple cavities. At least one air passage 333 is provided on the end face of the base 33 near the sole 10. Each air passage 333 connects to at least two through holes 331, and the through holes 331 communicate with the cavities. Each air passage 333 can connect to two adjacent through holes 331, thus the two cavities corresponding to the two through holes 331 are also interconnected. When the shock absorber 31 is under pressure, the gas in the two cavities can circulate through the air passages 333, forming a shock-absorbing structure 30 similar to an air mattress. The number of air passages 333 can be, but is not limited to, one, two, three, four, or more.
[0083] Please see Figure 10 and Figure 11 In this embodiment, the shock-absorbing structure 30 can be disposed in the forefoot area 113 of the sole 10, and the shock-absorbing structure 30 can also be disposed in the heel area 115 of the sole 10. Preferably, the shock-absorbing structure 30 can be disposed in the entire sole area 11 (e.g., the entire foot area 11) of the sole 10. Figure 11(As shown). When the user's foot applies pressure to the forefoot area 113 of the sole 10, the shock-absorbing structure 30 located in the forefoot area 113 of the sole 10 will undergo a certain deformation to absorb shock and cushion the impact. The gas in the cavity of this shock-absorbing structure 30 can flow into the cavity of the shock-absorbing element 31 in the middle area 117 and the cavity of the shock-absorbing element 31 in the heel area 115 of the sole 10 through the air channel 333. As a result, the shock-absorbing elements 31 in the middle area 117 and the heel area 115 of the sole 10 will expand slightly, and the shock-absorbing elements 31 in the middle area 117 and the heel area 115 of the sole 10 will provide better support for the middle and heel of the user's foot. When the pressure exerted by the user's foot on the forefoot area 113 of the sole 10 disappears, the air in the cavity of the shock absorber 31 in the mid-section 117 of the sole 10 and the cavity of the shock absorber 31 in the heel area 115 of the sole 10 flows back into the cavity of the shock absorber 31 in the forefoot area 113 of the sole 10 through the air passage 333, so that the shock absorber 31 can rebound to its initial shape so that it can perform shock absorption and cushioning again next time.
[0084] When the user's foot applies pressure to the heel area 115 of the sole 10, the shock-absorbing structure 30 located in the heel area 115 of the sole 10 will undergo a certain deformation to absorb shock and cushion the impact. The gas in the cavity of this shock-absorbing structure 30 can flow through the air passage 333 into the cavity of the shock-absorbing element 31 in the middle area 117 and the cavity of the shock-absorbing element 31 in the forefoot area 113 of the sole 10. As a result, the shock-absorbing element 31 in the middle area 117 and the shock-absorbing element 31 in the forefoot area 113 of the sole 10 will expand slightly, and the shock-absorbing element 31 in the middle area 117 and the shock-absorbing element 31 in the forefoot area 113 of the sole 10 will provide better support for the foot. When the pressure exerted by the user's foot on the heel area 115 of the sole 10 disappears, the air in the cavities of the shock absorbers 31 in the mid-section 117 and forefoot area 113 of the sole 10 flows back into the cavity of the shock absorbers 31 in the heel area 115 of the sole 10 through the air passage 333. This allows the shock absorber 31 to rebound to its initial shape for subsequent shock absorption. As the airflow circulates within the shock-absorbing structure 30, it provides a more snug fit to the foot, thereby improving the support provided by the shock-absorbing sole 100 and resulting in more stable walking for the user.
[0085] Please see Figure 7 and Figure 8In some embodiments, the height H4 of the base 33 ranges from [1.0mm, 10.0mm]. When the height H4 of the base 33 is less than 1.0mm, the height H4 is too low, and the connection between the base 33 and the sole 10 is not stable enough. When the height H4 of the base 33 is greater than 10.0mm, the height H4 is too high, and the thickness of the shock-absorbing sole 100 is too thick, failing to meet the requirements of lightweight and aesthetically pleasing casual shoes. When the height H4 of the base 33 ranges from [1.0mm, 10.0mm], the connection between the base 33 and the sole 10 is more stable, and the height of the shock-absorbing structure 30 is lower, resulting in a thinner shock-absorbing sole 100, which meets the requirements of lightweight and aesthetically pleasing casual shoes.
[0086] For example, the height H4 of the base 33 can be 1.0mm, 1.4mm, 1.8mm, 2.1mm, 2.5mm, 2.8mm, 3.2mm, 3.7mm, 4.0mm, 5.4mm, 5.8mm, 6.2mm, 6.6mm, 7.5mm, 7.7mm, 8.1mm, 8.8mm, 9.1mm, or 10.0mm, etc. In this embodiment, the height H4 of the base 33 is 2.5mm. Further, the height H4 of the base 33 can also be in the range of [1.0mm, 4.0mm]. In this case, the height H4 of the base 33 is relatively low, resulting in a lower height of the shock-absorbing structure 30 and a thinner thickness of the shock-absorbing sole 100, which can better meet the requirements of lightweight and aesthetics for casual shoes.
[0087] Please see Figure 7 and Figure 8 In some embodiments, the height H5 of the shock absorber 31 ranges from 1.0mm to 25.0mm. When the height H5 of the shock absorber 31 is less than 1.0mm, the height H5 is too low, resulting in poor foot support and ineffective shock absorption and cushioning. This can lead to foot pain and discomfort during prolonged walking. When the height H5 of the shock absorber 31 is greater than 25.0mm, the height H5 is too high, making the sole 100 too thick, which does not meet the requirements of lightweight and aesthetically pleasing casual shoes. With the height H5 of the shock absorber 31 ranging from [1.0mm to 25.0mm], when the user's foot applies pressure to the shock absorber 31, the shock absorber 31 can withstand the pressure and undergo a certain deformation. While ensuring softness, it can play a role in shock absorption and cushioning, thereby reducing the impact force of the ground on the foot. Users are less likely to experience foot pain and discomfort during walking, and the user's wearing comfort is good.
[0088] For example, the height H5 of the shock absorber 31 can be 1.0mm, 2.3mm, 3.0mm, 4.4mm, 5.2mm, 5.6mm, 6.5mm, 7.0mm, 8.5mm, 12.0mm, 15.4mm, 16.1mm, 17.5mm, 18.7mm, 19.2mm, 20.4mm, 21.3mm, 23.5mm, 24.1mm, or 25.0mm, etc. In this embodiment, the height H5 of the shock absorber 31 is 7.0mm. Further, the height H5 of the shock absorber 31 can also be within the range of [3.0mm, 12.0mm]. In this case, the height H5 of the shock-absorbing structure 30 is relatively low, and the thickness of the shock-absorbing sole 100 is relatively thin. While meeting the requirements of lightweight and aesthetics for casual shoes, the shock absorber 31 can also play a good role in shock absorption and cushioning, making the user's wearing experience more comfortable.
[0089] Please see Figure 7 In some embodiments, the diameter D of the shock absorber 31 ranges from 3.0 mm to 50.0 mm. When the diameter D of the shock absorber 31 is less than 3.0 mm, the shock absorber 31 deforms significantly when pressure is applied by the user's foot. This results in a noticeable feeling of collapse and foreign body sensation when the foot applies force to the shock-absorbing structure 30, and the shock absorber 31 does not rebound easily, leading to foot fatigue during walking. The shock absorption and cushioning effect of the shock absorber 31 is also poor, causing foot pain and discomfort during prolonged walking. When the diameter D of the shock absorber 31 is greater than 50.0 mm, the density of the shock absorber 31 installed in the shock-absorbing structure 30 of the sole 10 is low, resulting in poor shock absorption and cushioning for the foot, and less comfortable wear for the user. With the diameter D of the shock absorber 31 ranging from [3.0mm to 50.0mm], the shock absorber 31 has a good shock absorption and cushioning effect during the user's walking process. The shock absorber 31 can effectively reduce the impact of the ground on the feet and avoid foot pain or discomfort during long-term walking.
[0090] For example, the diameter D of the shock absorber 31 can be 3.0mm, 4.3mm, 5.2mm, 6.0mm, 6.2mm, 6.5mm, 6.7mm, 7.0mm, 12.0mm, 18.7mm, 25.0mm, 26.3mm, 28.1mm, 29.6mm, 30.1mm, 32.5mm, 34.7mm, 38.2mm, 45.6mm, 48.1mm, or 50.0mm, etc. In this embodiment, the diameter D of the shock absorber 31 ranges from [6.0mm to 7.0mm]. Further, the diameter D of the shock absorber 31 can also range from [3.0mm to 25.0mm]. At this time, the shock absorber 31 in the shock-absorbing structure 30 installed on the sole 10 has a large density. During the user's walking process, the shock absorber 31 has a good shock absorption and cushioning effect. The shock absorber 31 can effectively reduce the impact of the ground on the foot and avoid the problem of foot pain or discomfort during long-term walking.
[0091] Please see Figure 7 Furthermore, in some embodiments, the shock-absorbing structure 30 further includes at least one reinforcing member 35, which extends from the base 33 in a direction away from the sole 10, and is disposed between two adjacent shock-absorbing members 31. Multiple reinforcing members 35 intersect each other and form multiple accommodating spaces 351, in which the shock-absorbing members 31 are disposed.
[0092] Preferably, the reinforcing member 35 can be integrally formed with the base 33, thereby simplifying the processing steps of the shock-absorbing structure 30. In this case, the material of the reinforcing member 35 is the same as that of the base 33. The number of reinforcing members 35 can be, but is not limited to, one, two, three, four, or more. The accommodating space 351 is used to accommodate the shock-absorbing member 31. Multiple reinforcing members 35 are staggered to form multiple accommodating spaces 351, each accommodating space 351 containing at least one shock-absorbing member 31. In this embodiment, each accommodating space 351 contains one shock-absorbing member 31; that is, multiple reinforcing members 35 are staggered to surround each shock-absorbing member 31, and at least a portion of the periphery of each shock-absorbing member 31 is provided with a reinforcing member 35. The distribution of the reinforcing members 35 on the base 33 can be, but is not limited to, a "V" shape, a "grid" shape, or an "A" shape. When the distribution of the reinforcing members 35 on the base 33 is a "well" shape, the structure of the shock-absorbing structure 30 is simple and the processing is relatively easy. When the reinforcement 35 is distributed in a "V" or "A" shape on the base 33, the shock absorber 31 has a larger deformation space within the accommodating space 351.
[0093] On the one hand, the reinforcing member 35 can be used to limit the shock absorber 31 within the accommodating space 351. When the foot applies pressure to the shock absorber 31, the reinforcing member 35 can prevent the shock absorber 31 from deforming significantly in a plane perpendicular to its height, thus providing more stable support for the foot and preventing instability during walking. On the other hand, the reinforcing member 35 also enhances the support performance of the shock-absorbing structure 30. When the foot applies pressure to the shock-absorbing structure 30, both the shock absorber 31 and the reinforcing member 35 can provide support, preventing excessive deformation of the shock-absorbing structure 30 and the problem of a noticeable collapse when the foot applies force to the shock-absorbing structure 30 during walking. In addition, since the reinforcing member 35 and the shock absorber 31 are made of the same material, the reinforcing member 35 will also deform under pressure and can rebound to its initial state when the pressure is removed. When the foot applies pressure to the shock-absorbing structure 30, the shock-absorbing component 31 deforms to provide shock absorption, while the reinforcing component 35 also deforms to a certain extent, thereby further enhancing the shock absorption and cushioning capacity of the shock-absorbing structure 30. Users can further avoid foot pain and discomfort during walking.
[0094] In one embodiment, the shock-absorbing structure 30 may not include the reinforcing member 35. In this case, the structure of the shock-absorbing structure 30 is simpler and easier to manufacture. For example, if the base 33 has an air duct 333, the shock-absorbing structure 30 may not require the reinforcing member 35. The shock-absorbing structure 30 of this embodiment can be provided in the full-length area 11 of the sole 10.
[0095] In another embodiment, the shock-absorbing structure 30 includes a reinforcing member 35. In this case, the shock-absorbing structure 30 provides more stable support for the foot and has a better shock absorption and cushioning effect. For example, if only a through hole 331 is provided on the base 33, the shock-absorbing structure 30 may include a reinforcing member 35. The shock-absorbing structure 30 of this embodiment can be located in the heel area 115 of the sole 10, in the forefoot area 113 of the sole 10, or in the entire sole area 11 of the sole 10.
[0096] Please see Figure 7 and Figure 8 In some embodiments, the ratio of the height H5 of the damping member 31 to the height of the reinforcing member 35 ranges from [1.15, 1.20]. For example, the ratio of the height of the damping member 31 to the height of the reinforcing member 35 can be 1.150, 1.156, 1.161, 1.167, 1.169, 1.172, 1.174, 1.178, 1.184, 1.187, 1.192, or 1.20, etc.
[0097] Specifically, the shock absorber 31 is the main structure in the shock absorption structure 30 used for shock absorption and buffering. In the height direction of the shock absorber 31, the height of the shock absorber 31 is usually higher than the height of the reinforcing member 35. Thus, when the foot applies pressure to the shock absorption structure 30, the shock absorber 31 can produce a certain deformation to support and dampen the foot.
[0098] When the ratio of the height H5 of the shock absorber 31 to the height of the reinforcing member 35 is less than 1.15, the height of the shock absorber 31 is higher than the height of the reinforcing member 35, but the height difference between them is small. When pressure is applied to the shock-absorbing structure 30 by the foot, the deformation of the shock absorber 31 is small, resulting in poor shock absorption and cushioning. This can easily lead to foot pain and discomfort for users after prolonged walking. When the ratio of the height H5 of the shock absorber 31 to the height of the reinforcing member 35 is greater than 1.20, the height of the shock absorber 31 is higher than the height of the reinforcing member 35, and the height difference between them is significant. The reinforcing member 35 provides poor restraint for the shock absorber 31. Under pressure, the portion of the shock absorber 31 above the reinforcing member 35 is prone to deformation and swaying in a plane perpendicular to its height, resulting in insufficient stability of the shock absorber 31's support for the foot. However, when the ratio of the height H5 of the shock absorber 31 to the height of the reinforcing member 35 is within the range of [1.15, 1.20], the reinforcing member 35 provides better restraint for the shock absorber 31. Under pressure, the shock absorber 31 is less prone to deformation and swaying in a plane perpendicular to its height, providing more stable support for the foot and preventing instability during walking. Furthermore, the shock absorber 31 deforms under pressure, effectively absorbing and cushioning shocks, further reducing foot pain and discomfort during walking and improving overall comfort.
[0099] Please see Figure 5 and Figure 6 In some embodiments, when the shock-absorbing structure 30 is installed in the heel region 115 of the sole 10, the heel region 115 includes a connected body portion 1151 and a sidewall 1153, forming an installation space 1155, within which the shock-absorbing structure 30 is installed. One side of the body portion 1151 is for direct contact with the ground, and the other side of the body portion 1151 is connected to the shock-absorbing structure 30. The sidewall 1153 extends from the periphery of the body portion 1151 toward the side closer to the shoe interior space 500, and the sidewall 1153 can limit the movement of the shock-absorbing structure 30 located within the installation space 1155.
[0100] Please see Figure 5 and Figure 6 In some embodiments, the height H6 of the body portion 1151 ranges from [1.5mm to 4.0mm]. When the height H6 of the body portion 1151 is less than 1.5mm, the height H6 is too low, making it prone to wear and tear during walking, resulting in a shorter lifespan and easier damage. When the height H6 of the body portion 1151 is greater than 4.0mm, the height H6 is too high, leading to an excessively thick sole 10, which does not meet the requirements for lightweight and aesthetically pleasing casual shoes. When the height H6 of the body portion 1151 ranges from [1.5mm to 4.0mm], the height H6 is relatively high, reducing the likelihood of damage during walking, and the overall thickness of the sole 10 is thinner, thus meeting the requirements for lightweight and aesthetically pleasing casual shoes.
[0101] For example, the height H6 of the body portion 1151 can be 1.5mm, 1.6mm, 1.8mm, 1.9mm, 2.0mm, 2.3mm, 2.4mm, 2.6mm, 2.7mm, 2.9mm, 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.9mm, or 4.0mm, etc. In this embodiment, the height H6 of the body portion 1151 is 3.5mm. Further, in some embodiments, the height H6 of the body portion 1151 can also be in the range of [3.0mm, 4.0mm]. In this case, the height H6 of the body portion 1151 is relatively high, so the body portion 1151 is less likely to be damaged when the user walks, and the overall thickness of the sole 10 is relatively thin, which can meet the requirements of lightweight and aesthetics for casual shoes.
[0102] Please see Figure 5In some embodiments, when the shock-absorbing structure 30 is installed in the heel area 115 of the sole 10, the height H7 of the shock-absorbing sole 100 in the heel area 115 ranges from [4.0mm, 39.0mm]. When the height H7 of the shock-absorbing sole 100 in the heel area 115 is less than 4.0mm, the height H7 is too low, and the shock-absorbing sole 100 is prone to wear and tear during walking, resulting in a shorter lifespan and easier damage. When the height H7 of the shock-absorbing sole 100 is greater than 39.0mm, the height H7 is too high, making the sole 10 too thick, which does not meet the requirements of lightweight and aesthetically pleasing casual shoes. With the height H7 of the shock-absorbing sole 100 ranging from [4.0mm to 39.0mm], the height H7 of the shock-absorbing sole 100 is relatively high, which makes it less likely for the shock-absorbing sole 100 to be damaged when the user walks. In addition, the overall thickness of the sole 10 is relatively thin, which can meet the requirements of lightweight casual shoes.
[0103] For example, when the shock-absorbing structure 30 is installed in the heel region 115 of the sole 10, the height H7 of the shock-absorbing sole 100 in the heel region 115 can be 4.0mm, 6.3mm, 7.5mm, 8.1mm, 10.0mm, 12.5mm, 14.7mm, 16.4mm, 18.1mm, 20.0mm, 22.5mm, 23.3mm, 24.7mm, 25.2mm, 26.4mm, 26.9mm, 27.2mm, 27.7mm, 28.9mm, or 39.0mm, etc. In this embodiment, the height H7 of the shock-absorbing sole 100 is 10.0mm. Further, the range of the height H7 of the shock-absorbing sole 100 in the heel region 115 is [4.0mm, 20.0mm]. At this point, the height H7 of the shock-absorbing sole 100 is relatively high, so the shock-absorbing sole 100 is less likely to be damaged when the user walks, and the overall thickness of the sole 10 is relatively thin, which can meet the requirements of lightweight casual shoes.
[0104] Please see Figure 5 In some embodiments, when the shock-absorbing structure 30 is installed in the heel region 115 of the sole 10, the ratio of the area of the shock-absorbing member 31 to the area of the heel region 115 of the sole 10 ranges from [6.0%, 42.0%]. For example, the ratio of the area of the shock-absorbing member 31 to the area of the heel region 115 of the sole 10 can be 6.0%, 8.7%, 11.8%, 18.7%, 23.5%, 26.7%, 29.1%, 31.2%, 35.4%, 37.8%, or 42.0%, etc.
[0105] When the ratio of the area of the shock-absorbing component 31 to the area of the heel region 115 of the sole 10 is less than 6.0%, the density of the shock-absorbing component 31 in the heel region 115 of the sole 10 is low, resulting in poor support and shock absorption for the foot. This can lead to foot pain and discomfort after prolonged walking. Conversely, when the ratio of the area of the shock-absorbing component 31 to the area of the heel region 115 of the sole 10 is greater than 42.0%, the density of the shock-absorbing component 31 in the heel region 115 of the sole 10 is high. Adjacent shock-absorbing components 31 hinder each other's deformation, resulting in less deformation of the shock-absorbing component 31 under pressure and poorer shock absorption. When the ratio of the area of the shock absorber 31 to the area of the heel region 115 of the sole 10 is in the range of [6.0%, 42.0%], the shock absorber 31 provides good support for the foot. Furthermore, the shock absorber 31 can undergo a certain deformation during the compression process, resulting in a good cushioning effect and greater comfort for the user.
[0106] Please see Figure 1 In some embodiments, the forefoot region 113, the midfoot region 117, and the heel region 115 of the sole 10 extend in the same direction. In this case, the sole 10 is a flat sole, and during walking, the forefoot region 113, the midfoot region 117, and the heel region 115 of the sole 10 can all simultaneously contact the ground. In this embodiment, the shock-absorbing structure 30 can be located in the forefoot region 113 of the sole 10, the heel region 115 of the sole 10, or the entire sole region 11 (forefoot region 113, midfoot region 117, and heel region 115) of the sole 10.
[0107] Please see Figure 12 and Figure 13In other embodiments, the mid-sole region 117 and the heel region 115 of the sole 10 are on the same horizontal plane, and the forefoot region 113 of the sole 10 extends from the mid-sole region 117 and curves upward toward the upper 300. The advantages of the curved forefoot region 113 are: firstly, the upward design makes the foot more comfortable; secondly, during descent, the forefoot region 113 provides more support to the forefoot, thus improving comfort. In this case, during walking, both the mid-sole region 117 and the heel region 115 of the sole 10 can simultaneously contact the ground, while the portion of the forefoot region 113 connected to the mid-sole region 117 of the sole 10 can contact the ground, and the portion of the forefoot region 113 away from the mid-sole region 117 of the sole 10 may not contact the ground. For the case where the shock-absorbing structure 30 is located in the forefoot region 113 of the sole 10, please refer to [link to relevant documentation]. Figure 12 In one example, the shock-absorbing structure 30 covers the forefoot area 113. When the foot applies pressure to the shock-absorbing structure 30, the shock-absorbing structure 30 provides good support to the forefoot area 113 of the foot, and the shock-absorbing element 31 can deform to absorb shock and cushion the impact, thereby reducing the impact of the ground on the forefoot area 113 of the foot and preventing pain and discomfort in the forefoot area 113 of the user's foot during long-term walking.
[0108] Please see Figure 13 In another example, the shock-absorbing structure 30 covers at least half of the area where the forefoot region 113 and the midfoot region 117 meet. During walking, approximately half of the area where the forefoot region 113 and the midfoot region 117 of the sole 10 meet will be in contact with the ground. Placing the shock-absorbing structure 30 in this area of the forefoot region 113 of the sole 10 reduces the usable area of the shock-absorbing structure 30, saving on material costs. Furthermore, the shock-absorbing structure 30 effectively reduces the impact of the ground on the foot, providing better cushioning and shock absorption, resulting in greater comfort for the user and preventing foot pain and discomfort during prolonged walking.
[0109] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
