Description

An insole used to relieve fasciitis Technical Field

[0001] This utility model relates to the field of insole technology, specifically to an insole for relieving fasciitis. Background Technology

[0002] Insoles are usually removable and located inside the shoe, directly contacting the sole of the foot. They are used to increase comfort, wick away moisture, and so on. Their main function is to increase the comfort of the shoe. They can provide extra support and cushioning, and when you walk in the shoes, they relieve pressure on your feet, making your feet feel more comfortable.

[0003] Some insoles now incorporate arch support plates with added firmness to enhance support for the arch of the foot. When worn, these plates support the arch, maintaining normal foot structure, distributing pressure, and improving body alignment. This reduces foot fatigue and the risk of injury, while also improving stability during exercise or walking. By conforming to the arch curve, it helps distribute pressure appropriately during dynamic activities, preventing excessive localized loads and contributing to maintaining overall skeletal and muscular balance.

[0004] Some insoles with arch support plates have a heel cup at the heel. The heel cup is integrally molded with the arch support plate. The heel cup can improve the wrapping effect of the sole and heel when the arch support plate supports the arch. However, the shape of the heel cup is mostly curved, and the curve extends to the top in a U-shape. When placed in the shoe, the curvature of the heel can easily cause the heel to roll sideways inside the shoe, making it difficult to improve the stability of the heel when supporting the arch and increasing the likelihood of pronation. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an insole for relieving fasciitis.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an insole for relieving fasciitis, comprising an insole body, an arch support plate disposed at the lower end of the insole body, and a heel cup disposed on the arch support plate and located at the heel position, characterized in that: it further comprises a platform surface disposed on the lower end surface of the arch support plate and located at the heel position, a buffer opening formed on the arch support plate and located at the heel position, and a buffer protrusion disposed at the lower end of the insole body and located within the buffer opening, wherein the arch support plate, the platform surface, the heel cup, and the buffer opening are integrally formed.

[0007] A further improvement is that the platform surface is a U-shaped platform or a parallel surface.

[0008] A further improvement is that the insole body is provided with an installation area for mounting the arch support plate.

[0009] A further improvement is the integration of the cushioning bumps with the insole body.

[0010] A further improvement is that the upper surface of the insole body is provided with a fascia groove, and a support pad is provided inside the fascia groove.

[0011] A further improvement is that the support pad is an elastic pad or a flexible pad.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the insole is placed inside the shoe for wearing, the arch support plate can provide support for the arch of the foot, the heel cup improves the wrapping effect on the sole and heel, and the platform surface allows the heel part of the insole to be in parallel contact with the shoe, so that when the arch support plate supports the arch, it can limit the lateral movement of the heel, prevent the heel from rolling over inside the shoe, improve the stability of the heel, and reduce the likelihood of pronation. The cushioning protrusions can also improve the shock absorption and cushioning effect of the heel, reducing the impact on the heel during activities such as walking and running, and protecting the bones and surrounding tissues from damage.

[0013] Further benefits: When installing the arch support plate onto the insole body, the cushioning protrusions and cushioning openings can help position the arch support plate on the insole body, facilitating the aligned installation of the arch support plate.

[0014] Further benefits: The two sides of the platform surface are connected to the curved surface of the heel cup. Through the setting of the heel cup and the platform surface on the arch support plate, it can provide support for the arch of the foot and planar support for the heel, provide anti-rollover effect for the heel, and make it easier to put the insole into the shoe.

[0015] Further benefits: A corresponding heel cup is also provided at the heel position of the insole body. When the arch support plate is installed on the insole body, the arch support plate can be made to fit tightly on the insole body, thereby further ensuring the lateral limiting effect of the heel cup on the heel position.

[0016] Further benefits: The mounting area allows the arch support plate to fit more easily against the insole body when it is installed on the insole body.

[0017] Further benefits: The cushioning bumps can also be installed separately. After the arch support plate is installed on the insole body, the cushioning bumps are then installed at the cushioning opening.

[0018] Further benefits: The support pad forms a raised feature on the insole body. When the foot steps down and the arch support plate supports the arch of the foot, the plantar fascia overlaps with the support pad. The support pad provides flexible or elastic support to the plantar fascia, which can reduce the stretching range of the plantar fascia during exercise or walking and act as a buffer when the plantar fascia is stretched, thereby reducing the occurrence of plantar fasciitis and relieving the pain of plantar fasciitis.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] Referring to Figures 1 to 5, the technical solution adopted in this specific embodiment is: an insole for relieving fasciitis, including an insole body 1, an arch support plate 2 disposed at the lower end of the insole body 1, a heel cup 3 disposed on the arch support plate 2 and located at the heel position, a platform surface 4 disposed on the lower end surface of the arch support plate 2 and located at the heel position, a buffer opening 5 opened on the arch support plate 2 and located at the heel position, and a buffer protrusion 6 disposed at the lower end of the insole body 1 and located within the buffer opening 5. The arch support plate 2, the platform surface 4, the heel cup 3, and the buffer opening 5 are integrally formed. The insole body 1 is composed of a sponge layer and an EVA layer. An arch support plate 2 is installed at the lower end of the EVA layer, and cushioning protrusions 6 are placed on top of the EVA layer. The sponge layer provides softness when in contact with the sole of the foot, while the EVA layer provides elasticity. Alternatively, the insole body 1 can consist of only one layer of sponge or EVA, with varying heights and thicknesses at the arch position or within the insole itself. This allows for support of the lateral or medial arch, or both. The thickness can be adjusted to enhance softness or rebound, and the height and thickness provide support and cushioning for fasciitis, alleviating pain caused by fasciitis stretching when the foot is pressed down. The arch support plate 2 can be made of a material with sufficient rigidity to support the arch, such as TPU or nylon. The cushioning opening 5 is larger than the size of the cushioning protrusions 6, allowing for a gap fit between the opening and the protrusions. The arch support plate 2 is fixed to the lower end of the insole body 1 by heat pressing or adhesive bonding.

[0028] The platform surface 4 is either a U-shaped platform or a parallel surface. Alternatively, both a parallel surface and a U-shaped surface can coexist. A corresponding U-shaped surface or parallel surface is also provided at the heel of the insole body 1 so that the U-shaped platform or parallel surface of the arch support plate 2 fits against the insole body 1.

[0029] The insole body 1 is provided with an installation area 7 for mounting the arch support plate 2. The shape of the installation area 7 corresponds to the shape of the arch support plate 2.

[0030] The cushioning protrusion 6 is integrally formed with the insole body 1.

[0031] The upper surface of the insole body 1 is provided with a fascia groove 8, and a support pad 9 is disposed within the fascia groove 8. As shown in Figure 5, the fascia groove 8 is positioned along the location of plantar fasciitis, close to the medial arch of the foot. When the insole body 1 is configured as a double layer (sponge and EVA), the fascia groove 8 is formed on the bottom layer, and the support pad 9 is placed in the fascia groove 8 of the bottom layer. Subsequently, the top layer presses the support pad 9 onto the bottom layer, which is located in the fascia groove 8. The support pad 9 is fixed to the insole body 1 by adhesive or heat pressing.

[0032] The support pad 9 is an elastic or flexible pad. The support pad 9 is made of a material with a hardness of 10-20 Shore A, or other soft pads can be selected. The hardness of EVA foam is between 30-40 Shore A, therefore the material selection for the support pad 9 needs to have a low hardness at the contact surface with the insole to improve the cushioning support for the plantar fascia.

[0033] The working principle of this utility model is as follows: When the insole is placed inside the shoe for wearing, the arch support plate 2 provides support for the arch of the foot, the heel cup 3 improves the wrapping effect on the sole and heel, and the platform surface 4 allows the heel part of the insole to be in parallel contact with the foot inside the shoe. This allows the arch support plate 2 to support the arch of the foot and restrict the lateral movement of the heel, preventing the heel from rolling over inside the shoe. This improves the stability of the heel and makes it less likely to increase the phenomenon of pronation. The cushioning protrusion 6 improves the shock absorption and cushioning effect of the heel. During activities such as walking and running, the impact force on the heel is reduced, protecting the bones and surrounding tissues from damage.

[0034] When installing the arch support plate 2 onto the insole body 1, the setting of the cushioning protrusion 6 and the cushioning opening 5 can achieve the positioning effect of the arch support plate 2 on the insole body 1, so as to facilitate the alignment and installation of the arch support plate 2.

[0035] The two sides of the platform surface 4 are connected to the arc-shaped surface of the heel cup 3. By setting the heel cup 3 and the platform surface 4 on the arch support plate 2, the arch support effect and the flat support of the heel position can be achieved, providing anti-rollover effect for the heel and making it easy to put the insole into the shoe.

[0036] A corresponding heel cup is also provided at the heel position of the insole body 1. When the arch support plate 2 is installed on the insole body 1, the arch support plate 2 can be made to fit tightly on the insole body 1, thereby further ensuring the lateral limiting effect of the heel cup 3 on the heel position.

[0037] The mounting area 7 is used to make it easier for the arch support plate 2 to fit the insole body 1 when the arch support plate 2 is installed on the insole body 1;

[0038] The cushioning protrusion 6 can also be set separately. After the arch support plate 2 is installed on the insole body 1, the cushioning protrusion 6 is then installed at the position of the cushioning opening 5.

[0039] The support pad 9 forms a raised feature on the insole body 1. When the foot steps down and the arch support plate 2 supports the arch of the foot, the plantar fascia overlaps with the support pad 9. The support pad 9 provides flexible or elastic support to the plantar fascia, which can reduce the stretching range of the plantar fascia during exercise or walking and act as a buffer when the plantar fascia is stretched, thereby reducing the occurrence of plantar fasciitis and relieving the pain of plantar fasciitis.
