Abstract
Description
Technical Field
[0001] This utility model relates to the field of insole technology, and in particular to an orthotic insole. Background Technology
[0002] During daily activities such as walking and standing, the feet need to continuously bear the weight of the body. As an important support structure of the feet, the shape and stress state of the arch directly affect foot health and overall comfort. Most ordinary insoles on the market are made of a single material and only have basic cushioning functions. They lack a special support design for the arch. Long-term use can easily cause the arch to gradually collapse due to uneven stress, leading to foot shape abnormalities such as flat feet and high arches, which in turn are accompanied by discomfort symptoms such as soreness in the soles of the feet and ankle fatigue when walking. Meanwhile, the insoles of ordinary shoes are mostly of uniform thickness in the forefoot and heel areas, which cannot provide targeted cushioning according to the different pressure distribution in different areas of the foot. As one of the main stress points when walking, the forefoot is prone to pain due to concentrated pressure. The heel bears a large impact force when landing, and if the cushioning is insufficient, it can easily cause extra burden on the ankle, knee joint, etc. Utility Model Content
[0003] To address the technical problems existing in the background art, this utility model proposes a shoe orthotic insole.
[0004] This utility model proposes an orthotic insole, comprising an insole body, wherein a rigid support member is connected to the arch portion of the insole body, the rigid support member having a harder hardness than the insole body, a first pad and a second pad are respectively glued and fixed to the forefoot portion of the insole body, the first pad and the second pad having different thicknesses, and a third pad is connected to the heel portion of the insole body, wherein the first pad, the second pad and the third pad are all made of elastic material to improve comfort.
[0005] Furthermore, the first pad and the second pad have a common clearance groove at the end facing the rigid support to avoid interference with the rigid support.
[0006] Furthermore, a first groove is formed in the arch portion of the pad, and the rigid support is bonded and fixed inside the first groove, and is compatible with it.
[0007] Furthermore, the rigid support is made of plastic to support the arch of the foot and prevent it from deforming.
[0008] Furthermore, a second groove is formed in the heel portion of the pad, and the third pad is bonded and fixed inside the second groove and is adapted to fit it, with the third pad protruding from the second groove.
[0009] Furthermore, the pad includes a surface layer, and the upper and lower surfaces of the surface layer are respectively bonded and fixed with a substrate layer and a bottom layer.
[0010] Furthermore, the surface layer is a polyurethane foam layer, the substrate layer is a non-woven fabric layer, and the bottom layer is an EVA foam layer.
[0011] Furthermore, a core patch is adhered and fixed to the front of the pad and at the position corresponding to the sole of the foot. The core patch is made of silicone or plastic foam material.
[0012] The beneficial effects of this utility model are as follows: By setting a rigid support member with a hardness greater than that of the insole in the arch area, a special support is provided for the arch to prevent it from collapsing due to uneven force, effectively improving foot deformities such as flat feet and high arches, as well as the resulting foot pain and ankle fatigue. At the same time, the elastic first and second pads of different thicknesses in the sole can be specifically adapted to the pressure distribution differences in the sole area of the foot, and the elastic third pad protruding from the second groove in the heel can fully absorb the impact force of the heel landing. These features solve the problems of forefoot pain caused by concentrated pressure in ordinary insoles and the extra burden on the ankle and knee joints caused by insufficient heel cushioning. While achieving foot correction, the comfort of wearing the shoes is significantly improved. Attached Figure Description

[0015] Reference Figure 1-4This utility model proposes a foot orthotic insole, including an insole body 1. The insole body 1 adopts a multi-layer composite structure design, specifically composed of a top layer 11, a base layer 12, and a bottom layer 13. The top layer 11 is located at the top and directly contacts the foot. Its material is a polyurethane foam layer, which has the characteristics of being soft, skin-friendly, and moderately elastic. It can reduce friction between the foot and the insole and improve the tactile comfort when wearing it. The base layer 12 is bonded and fixed to the lower surface of the top layer 11. The base layer 12 is made of non-woven fabric. Non-woven fabric has good breathability and structural stability. It can not only help to disperse foot pressure, but also enhance the overall tensile strength of the insole body 1 and prevent the insole body from deforming after long-term use. The bottom layer 13 is bonded and fixed below the base layer 12. The bottom layer 13 is made of EVA foam layer. EVA material has the characteristics of being lightweight, wear-resistant, and compression-resistant. It can effectively extend the service life of the insole and reduce the slippage between the insole and the sole, ensuring stability when wearing it. To achieve the corrective support function for the arch of the foot, a first groove 7 is opened at the corresponding position of the arch of the pad 1. The shape of the first groove 7 is adapted to the arch curve. A rigid support 2 is bonded and fixed inside it, and the size of the rigid support 2 is completely matched with the first groove 7 to ensure that the rigid support 2 can be stably embedded in the pad 1 without displacement. The rigid support 2 is made of plastic, and its hardness is much greater than the overall hardness of the pad 1. When worn, it can form rigid support for the arch of the foot, preventing the arch of the foot from collapsing or deforming due to long-term stress, thereby achieving the effect of correcting the arch shape and relieving arch fatigue. To address the needs for pressure distribution and comfort in the sole area, a first pad 3 and a second pad 4 are respectively bonded and fixed to the sole area of the pad body 1. Both are made of elastic materials (such as elastic rubber or soft foam materials), which can generate elastic deformation when the foot is stepped on to absorb impact. At the same time, the thickness of the first pad 3 and the second pad 4 is set to different specifications, which can be used to increase the cushioning effect of specific areas according to the pressure distribution differences in the sole area of different users (such as some users have greater pressure on the inner side of the forefoot and some users have greater pressure on the outer side). This differentiated thickness design further optimizes the force balance in the sole area and reduces discomfort caused by walking or standing for a long time. Considering that there may be positional interference between the first pad 3, the second pad 4 and the rigid support 2 during assembly, a clearance groove 6 is opened at the end of the first pad 3 and the second pad 4 facing the rigid support 2. The size of the clearance groove 6 is adapted to the edge contour of the rigid support 2. After the components are assembled, the end of the rigid support 2 can be embedded in the clearance groove 6 to avoid direct contact and squeezing between the two. This ensures the installation stability of each component and prevents the insole from bulging or deforming locally due to interference, which would affect the wearing experience. To enhance the cushioning and support of the heel area, a second groove 8 is made at the corresponding position of the heel on the pad 1. A third pad 5 is glued and fixed inside the second groove 8. The third pad 5 is also made of elastic material and its size matches the second groove 8 to ensure that it will not loosen after installation. At the same time, the thickness of the third pad 5 is greater than the depth of the second groove 8, so that the third pad 5 will protrude from the surface of the second groove 8 after assembly. When the foot steps on it, the protruding third pad 5 can make contact with the heel first and fully absorb the impact force when the heel lands through elastic deformation, reducing the pressure on the ankle and leg joints and further improving the overall wearing comfort. In addition, a core patch 9 is glued and fixed on the front of the pad 1 and at the position corresponding to the sole of the foot. The core patch 9 is a type of silicone or plastic foam material. The position of the core patch 9 corresponds to the Yongquan acupoint on the human body. The Yongquan acupoint is located at the bottom of the foot with a slightly concave arc. After the core patch 9 is in contact with the foot, walking can be more stable, making the sole of the foot and the shoe more balanced.
[0016] The functions and effects of stimulating or massaging the soles of the feet mainly include the following aspects: Regulating blood circulation: The Yongquan acupoint on the sole of the foot belongs to the Kidney Meridian of Foot-Shaoyin. Massaging this acupoint can regulate blood circulation. You can usually press this acupoint with your thumb for about 10 minutes each time. Long-term adherence to this method can help regulate blood circulation.
[0017] Improving sleep: Regularly massaging the soles of the feet can promote local blood circulation and improve poor sleep quality. If you experience symptoms such as insomnia or difficulty falling asleep, you can massage the soles of your feet appropriately under the guidance of a doctor to promote sleep.
[0018] Relieving fatigue: Gentle foot massage can relieve fatigue to some extent. If you experience excessive fatigue, massaging the soles of your feet can also alleviate discomfort such as weakness and soreness.
[0019] Promote metabolism: The soles of the feet have many blood vessels. By tapping the soles of the feet every day, patients can accelerate blood circulation in the feet and the whole body, thereby promoting metabolism.
[0020] Improving sleep quality: Patients can improve their sleep quality by tapping the soles of their feet daily, which can relieve tension and insomnia symptoms.
[0021] Unblocking meridians: Massaging the corresponding parts of the soles of the feet can unblock meridians, regulate metabolism, harmonize the internal organs, and increase the body's resistance.
[0022] In summary, the functions and effects of the Yongquan acupoint on the sole of the foot mainly focus on regulating blood circulation, improving sleep, relieving fatigue, promoting metabolism, improving sleep quality, and unblocking meridians. It is important to note that when massaging the sole of the foot, the pressure should be controlled to avoid excessive force. The functions mentioned above are known existing technologies and functions, not inventions of this patent; they are merely descriptions of the benefits of the Yongquan acupoint on the sole of the foot.
[0023] In actual use, after the user puts the insole into the shoe, the foot fits against the surface layer 11 of the insole body 1. The arch area is provided with stable support by the rigid support component 2, which effectively maintains the physiological curvature of the arch. The forefoot area achieves differentiated cushioning through the first pad 3 and the second pad 4 of different thicknesses to balance the pressure on the forefoot. The heel area relies on the third pad 5 protruding from the second groove 8 to absorb the impact. All components work together to achieve the arch correction function while maximizing the comfort and stability of wearing the shoe.
