Description

Technical Field

[0001] This application relates to the field of footwear technology, and more specifically, to outsoles, midsoles, and shoes that facilitate walking. Background Technology

[0002] Modern women's leather shoes / boots are commonly flat or have a certain heel. These shoes usually consist of two parts: the sole and the upper. The sole is typically quite hard, resulting in less comfort. While they are generally comfortable for everyday wear, they can be tiring for extended periods of walking. Women's leather shoes are relatively formal, and due to considerations of etiquette and aesthetics, they are a common choice for many women. The inherent problem with these shoes is their lower comfort level, especially in situations requiring prolonged standing or walking (which are often unavoidable). Utility Model Content

[0003] The purpose of this application is to provide an outsole, a midsole, and a shoe that are easy to walk in, and the outsole, midsole, and shoe that are easy to walk in provide better comfort.

[0004] To achieve the above objectives, in a first aspect, this utility model provides a sole that facilitates walking, comprising: The outsole body has a hollow interior, and a foot support ridge and a heel support ridge are fixedly installed in the hollow area. The foot support ridge includes multiple wave-shaped foot support ridges fixedly installed on the inner wall of the outsole body.

[0005] In an optional embodiment, the foot support ridge further includes a straight foot support ridge, and at least two straight foot support ridges are provided at equal intervals on each of the wave-shaped foot support ridges.

[0006] In an optional embodiment, the heel support ridge is configured in a grid pattern.

[0007] Secondly, this utility model provides a midsole that facilitates walking, comprising: The midsole body has mounting holes corresponding to the foot area; A raised plate, which is installed in the mounting hole of the midsole body, has a plurality of raised points.

[0008] In an optional embodiment, the raised plate includes a plate body and a plurality of raised points. The plate body is fixedly installed in the mounting hole of the midsole body, and a plurality of raised points are fixedly disposed on the plate body.

[0009] In an optional embodiment, the radius of the protrusion is R, and the height of the protrusion is H, wherein 5mm≤R≤7mm, and 1mm≤H≤4mm.

[0010] In an optional embodiment, a bottom support pad is also included, which is fixedly installed on the end face of the midsole body away from the protrusion point, and the protrusion plate is fixedly connected to the bottom support pad.

[0011] In an optional embodiment, the support pad is configured as a mesh structure.

[0012] In an optional embodiment, a rigid support plate is also included, which is fixedly disposed on the midsole body at the heel position and located on the end face away from the protruding point.

[0013] Thirdly, this utility model provides a shoe that facilitates walking, including an insole; It also includes a large sole as described in any of the foregoing embodiments, or a midsole as described in any of the foregoing embodiments.

[0014] In this application, the wave-shaped foot support ridge of the outsole is a support structure extending along the wave line, making the outsole more prone to deformation when subjected to foot flexion forces.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1 As shown, in a first aspect, embodiments of this application provide a sole that facilitates walking, including a sole body 100, the sole body 100 being hollowed out to reduce the weight of the sole.

[0023] The outsole is in contact with the road surface.

[0024] The outsole body 100 has a hollowed-out section where a foot support ridge 110 and a heel support ridge 120 are fixedly installed. The foot support ridge 110 includes multiple wave-shaped foot support ridges 111 fixedly installed on the inner wall of the outsole body 100.

[0025] The heel support ridge 120 is positioned on the outsole body 100 corresponding to the user's heel, and the heel support ridge 120 is used to support the user's heel.

[0026] The wave-shaped foot support ridge 111 is positioned on the outsole body 100 to correspond to the position of the user's foot, so as to support the user's foot.

[0027] For example, the wave-shaped foot support ridge 111 is integrally formed with the inner wall of the outsole body 100.

[0028] For example, the wave-shaped foot support ridge 111 is a support structure that extends along the wave line.

[0029] For example, the spacing between two adjacent wave-shaped foot support ridges 111 is 10 mm. Of course, in other embodiments, other spacing distances can be set between two adjacent wave-shaped foot support ridges 111, such as 15 mm or 16 mm.

[0030] In this application, a heel support ridge 120 is provided in the hollowed-out part of the outsole body 100, and its position corresponds to the user's heel. The heel support ridge 120 can provide stable support for the user's heel, distribute the pressure on the heel when walking and standing, reduce fatigue and injury in the heel area, and enhance the comfort and stability of wearing.

[0031] In this application, the wave-shaped foot support ridge 111 is a support structure extending along the wave line. This special shape design makes the outsole more prone to deformation when subjected to foot flexion forces. In long-term walking environments, the outsole can naturally flex with the user's foot instead of hindering normal foot movement.

[0032] In this application, the outsole follows the bending and deformation of the foot, providing more room for movement. The foot can extend and contract more freely during walking, reducing the squeezing and restraint caused by shoe limitations, thus significantly improving wearing comfort, especially suitable for occasions requiring long periods of walking or standing.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the foot support ridge 110 further includes a straight foot support ridge 112, and at least two straight foot support ridges 112 are provided at equal intervals on each wave-shaped foot support ridge 111.

[0034] For example, each wave-shaped foot support ridge 111 is provided with two straight foot support ridges 112. In another embodiment, each wave-shaped foot support ridge 111 may also be provided with other numbers of straight foot support ridges 112, such as three, four or five.

[0035] The linear foot support spine 112 increases the number of support points in the foot. During walking, the foot bears the weight of the body and generates forces in various directions. Multiple linear foot support spines 112 can work in conjunction with the wave-shaped foot support spine 111 to provide support to the foot from different positions and angles, making the support more balanced and stable, and reducing fatigue and injury caused by excessive local force on the foot.

[0036] The evenly spaced linear foot support ridges 112 can distribute the pressure on the foot more evenly across the entire foot support ridge structure 110. Compared to relying solely on the wave-shaped foot support ridges 111, this pressure distribution method can reduce the peak pressure at each support point, further improving the stability and reliability of the support, making the wearer feel more secure when walking.

[0037] The straight foot support ridge 112 and the wave-shaped foot support ridge 111 work together to form a support structure. The straight structure has high rigidity, which can enhance the deformation resistance of the entire foot support ridge 110. Under prolonged walking or when subjected to large external forces, this structure can better maintain its shape and support performance, and is not prone to excessive deformation, thus ensuring the comfort and functionality of the shoe.

[0038] Although the straight foot support spine 112 increases the rigidity of the structure, the reasonable setting of equal spacing does not excessively restrict the flexibility of the foot. On the contrary, it works in conjunction with the wave-shaped foot support spine 111 to ensure support stability while still allowing the foot to have a certain amount of natural bending and movement space, so that the wearer can feel a more natural and comfortable walking experience.

[0039] like Figure 2 As shown, in one embodiment, the heel support ridge 120 is configured in a grid pattern.

[0040] The interlacing lines of the crisscross pattern create a stable framework. During walking, standing, or exercise, this multi-directional support structure restricts heel movement from different directions, reducing heel wobble and displacement within the shoe and providing more reliable stability. Especially when performing actions requiring quick changes of direction or balance, stable heel support helps the wearer maintain better balance and reduces the risk of sports injuries such as sprains.

[0041] like Figure 3 and Figure 4 As shown, in a second aspect, embodiments of this application provide a midsole that facilitates walking, including a midsole body 200 and a raised plate 210.

[0042] Mounting holes are provided on the main body of the midsole 200 corresponding to the foot.

[0043] For example, the mounting hole is a through hole. However, in other embodiments, the mounting hole may also be configured as a blind hole.

[0044] The raised plate 210 is installed in the mounting hole of the midsole body 200, and the raised plate 210 has multiple raised points 212.

[0045] Because of the insole 300, when the midsole is applied to the shoe, the insole 300 contacts the user's foot, the midsole is located below the insole 300, and the outsole is located below the midsole. Therefore, the raised points 212 on the midsole will not directly contact the user's foot and will not cause excessive friction on the foot.

[0046] The raised plate 210 may be made of polyurethane, and the material of the midsole body 200 may be, for example, nylon, silicone, or rubber. In other embodiments, the raised plate 210 may be made of materials such as rubber or silicone.

[0047] Existing technologies using rigid midsoles with built-in metal strips severely restrict the flexion of the foot, leading to foot fatigue during prolonged walking. This application addresses this by incorporating mounting holes and a raised plate 210 at the foot-facing location on the midsole body 200, reducing the rigidity of the midsole body 200 at this point. This allows the midsole body 200 to better flex and deform in response to the user's foot movements, providing greater range of motion and reducing the restriction on foot flexion caused by an overly rigid sole. This significantly improves walking comfort, making it particularly suitable for extended walking sessions.

[0048] Because the midsole better adapts to the flexion of the foot, the foot does not need to exert excessive force to overcome the resistance of the sole during walking, allowing for more natural movement. This helps to distribute the pressure on the foot, avoiding excessive localized pressure, thereby reducing fatigue in the foot muscles and joints, and making the wearer less prone to foot pain after walking.

[0049] The multiple raised points 212 on the raised plate 210 provide excellent cushioning. When a user walks, the ball of the foot applies pressure to the midsole, and the raised points 212 deform to a certain extent, thereby absorbing and dispersing some of the impact force and reducing the reaction force of the ground on the ball of the foot. This cushioning effect can effectively reduce the vibration and impact on the ball of the foot during walking, protect the bones, joints and soft tissues of the foot, reduce the risk of injury, and further improve walking comfort and safety.

[0050] In the embodiments of this application, when the midsole is applied to a shoe, because an insole 300 is provided inside the shoe, the raised points 212 on the midsole will not directly contact the user's sole, thereby avoiding excessive friction of the raised points 212 on the sole skin. The insole 300, as an insulating layer between the sole and the midsole, provides a soft contact surface, reducing discomfort and wear that may be caused by direct contact with the raised points 212, further improving wearing comfort.

[0051] like Figure 3 As shown, in one embodiment, the raised plate 210 includes a plate body 211 and a plurality of raised points 212. The plate body 211 is fixedly installed in the mounting hole of the midsole body 200, and a plurality of raised points 212 are provided on the plate body 211.

[0052] For example, three protruding points 212 are spaced apart on the plate body 211; in another embodiment, four protruding points 212 are spaced apart on the plate body 211; of course, other numbers of protruding points 212 can also be provided, for example, five, six or ten protruding points 212 are provided on the plate body 211 in other embodiments.

[0053] For example, the mounting hole is a rectangular hole, and the plate body 211 is a rectangular plate body adapted to the mounting hole. In another embodiment, the mounting hole is a circular hole, and the plate body 211 is a circular plate body adapted to the mounting hole. In another embodiment, the mounting hole is a rectangular hole with a transition arc provided at the connection of two adjacent sides, the plate body 211 is a rectangular plate body adapted to the mounting hole, and its rectangular plate body is provided with rounded corners.

[0054] In one embodiment, the radius of the protrusion 212 is R, and the height of the protrusion 212 is H, wherein 5mm≤R≤7mm, and 1mm≤H≤4mm.

[0055] For example, the protrusion 212 is a cylindrical structure, and the end of the protrusion 212 away from the plate portion 211 is a hemisphere.

[0056] For example, in one embodiment, the radius R of the protrusion 212 is 5 mm; in another embodiment, the radius R of the protrusion 212 is 6 mm; and in yet another embodiment, the radius R of the protrusion 212 is 7 mm.

[0057] When the radius of the raised point 212 is less than 5mm, the nerve endings on the surface of the skin are overstimulated during the contact between the sole and the sharp raised point 212, resulting in a "stinging sensation". Long-term use may cause pressure sores or blisters. When running or jumping, the relative sliding between the sole and the midsole will increase the friction of the sharp raised point 212, further reducing comfort.

[0058] When the radius of the protrusion 212 is greater than 7mm, the cross-sectional area of ​​the protrusion 212 is larger, the strength of the protrusion 212 increases, which leads to a decrease in the vibration absorption effect and also results in a poor user experience.

[0059] For example, in one embodiment, the height H of the protrusion 212 is 1 mm. In another embodiment, the height H of the protrusion 212 is 2 mm. In another embodiment, the height H of the protrusion 212 is 3 mm. In yet another embodiment, the height H of the protrusion 212 is 4 mm.

[0060] When the height of the protrusion 212 is less than 1mm, the amount of contraction of the protrusion 212 after compression is large. Excessive deformation prevents the protrusion 212 from rebounding quickly when the foot leaves the ground, reducing the continuous shock absorption capacity. The tiny protrusion 212 is prone to plastic deformation during repeated compression, leading to the collapse of the midsole structure.

[0061] When the height of the protrusion 212 is greater than 4mm, the protrusion 212 will still have a large volume after being pressed by the ball of the foot. The high protrusion 212 will press against the sole of the foot, causing a "prickly" feeling, which will aggravate fatigue, especially during long-distance exercise.

[0062] The 1-4mm raised point 212 height range, by controlling the deformation (usually designed as a compression ratio of 20%-50%), ensures sufficient shock absorption space while avoiding the interference of residual volume on the feet, thus achieving a synergy between functionality and comfort.

[0063] Unlike the above embodiment where the protruding point 212 is a cylindrical structure, in another embodiment, the protruding point 212 is a polygonal prism structure, such as a triangular prism, a quadrangular prism, a pentagonal prism, or a hexagonal prism. The end of the polygonal prism structure that is away from the plate portion 211 is a hemisphere or a plane end parallel to the plane where the plate portion 211 is located.

[0064] To further secure the raised plate 210 to the midsole body 200, such as... Figure 4 As shown, in one embodiment, the midsole also includes a bottom support pad 220, which is fixedly installed on the end face of the midsole body 200 away from the protrusion point 212, and the protrusion plate 210 is fixedly connected to the bottom support pad 220.

[0065] For example, the bottom support pad 220 is fixedly mounted on the midsole body 200 by means of adhesive or the like.

[0066] For example, the plate part 211 is fixedly mounted on the base pad 220 by means of adhesive bonding, pressing or integral molding.

[0067] The area of ​​the bottom support pad 220 is larger than the area of ​​the mounting hole. The bottom support pad 220 can increase the fixed connection area with the midsole body 200 and improve the connection strength between the bottom support pad 220 and the midsole body 200. Compared with the side wall of the plate part 211, which is only fixedly connected to the inner wall of the mounting hole, fixing the plate part 211 on the bottom support pad 220 can increase the installation reliability of the plate part 211.

[0068] In one embodiment, the base pad 220 is configured as a mesh structure to reduce weight.

[0069] In order to maintain the shape of the midsole body 200, such as Figure 4 As shown, in one embodiment, the midsole also includes a rigid support plate 230, which is fixedly disposed on the midsole body 200 at the heel and located on the end face away from the protrusion point 212.

[0070] A metal strip is also fixedly installed inside the rigid support plate 230. The metal strip is used to support the rigid support plate 230. The fixed connection between the metal strip and the rigid support plate 230 is, for example, riveting, pressing or gluing.

[0071] Thirdly, embodiments of this application provide shoes that facilitate walking, such as... Figure 5 As shown, the shoe includes an insole of 300.

[0072] like Figure 6 As shown, shoes designed for easy walking also include a midsole and an outsole as described in any of the above embodiments.

[0073] like Figure 6 As shown, in another embodiment, the walking shoe also includes an insole 300, an outsole as described in any of the above embodiments, and a midsole as described in any of the above embodiments.

[0074] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
