Abstract
Description
Technical Field
[0001] This utility model relates to the field of insole technology, and in particular to an orthotic insole and shoe for pigeon toes. Background Technology
[0002] Pigeon toes is a common gait problem in children, also known as "pronation foot". It is characterized by the toes pointing inward and the heels pointing outward when walking or standing, forming an "eight" shape.
[0003] In-toeing can be caused by a variety of factors, including congenital genetics, foot structural abnormalities, insufficient muscle strength, and incorrect walking or running posture. Although in-toeing is a normal part of growth and development in most cases, it can be problematic if it persists or severely affects a child's walking ability.
[0004] Currently, in addition to using orthotics and surgical treatment, the correction of in-toeing feet also involves footwear, especially insoles. However, most of these methods involve directly using flat foot insoles to correct in-toeing feet, thus classifying in-toeing feet and flat feet as one category.
[0005] For flat foot correction, a raised support component is usually placed on the inner side of the midfoot of the shoe sole or insole. This support component is relatively rigid and can support the medial arch, preventing excessive drooping of the medial arch and thus reducing the harm caused by flat feet. However, flat feet and pigeon toes have different causes. Placing a raised support component on the inner side of the midfoot only solves the problem of foot pronation and cannot solve the problem of foot rotation inward. Utility Model Content
[0006] The purpose of this invention is to provide an orthotic insole and sole for in-toeing foot correction.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An orthotic insole for inward-pointing toes includes an insole body, a mid-waist support pad, and a forefoot side support pad. The upper surface of the insole body is the body support surface. The mid-waist support pad protrudes from the body support surface and is located in the middle of the inner side of the insole body. The thickness of the mid-waist support pad gradually decreases from the inner side of the insole body to the outer side. The forefoot side support pad protrudes from the body support surface and is located in the front of the inner side of the insole body. The thickness of the forefoot side support pad gradually decreases from the inner side of the insole body to the outer side.
[0009] Furthermore, the curvature of the forefoot side support pad and the mid-waist support pad matches the curvature of their opposite sides, allowing for a smooth transition between the forefoot side support pad and the mid-waist support pad.
[0010] Furthermore, the width of the forefoot side support pad is 1 / 3 to 1 / 2 of the width of the insole body.
[0011] Furthermore, the hardness of the forefoot side support pad is greater than that of the insole body, and the hardness of the midfoot support pad is between that of the forefoot side support pad and the insole body.
[0012] Furthermore, the Shore hardness of the insole body is 38C-42C, the Shore hardness of the midfoot support pad is 45C-50C, and the Shore hardness of the forefoot side support pad is 43C-52C.
[0013] Furthermore, when the insole body is made of EVA material, the Shore hardness of the insole body is 38C; when the insole body is made of supercritical foam material, the Shore hardness of the insole body is 40C; when the midfoot support pad is made of EVA material, the Shore hardness of the midfoot support pad is 40C; when the midfoot support pad is made of supercritical foam material, the Shore hardness of the midfoot support pad is 42C; when the forefoot side support pad is made of EVA material, the Shore hardness of the forefoot side support pad is 43C; and when the insole body is made of supercritical foam material, the Shore hardness of the forefoot side support pad is 45C.
[0014] Furthermore, the mid-waist support pad and the forefoot side support pad are bonded and fixed to the main support surface of the insole body.
[0015] Furthermore, the thickness of the mid-waist support pad near the inner side of the insole body is 3-10mm, and the thickness of the mid-waist support pad gradually decreases to 0.2-0.5mm along the outer side and front and rear ends of the insole body; the thickness of the forefoot support pad near the inner side of the insole body is 2-5mm, and the thickness of the forefoot support pad gradually decreases to 0.2-0.5mm along the outer side of the insole body; the height difference between the main support surface and the upper surface of the forefoot support pad is 0.5-3mm.
[0016] An orthotic shoe sole for pigeon toes, having the aforementioned orthotic insole for pigeon toes.
[0017] This utility model has the following beneficial effects:
[0018] This invention provides an orthotic insole and sole for in-toeing feet, comprising a mid-waist support pad and a forefoot side support pad. The mid-waist support pad protrudes from the middle of the inner side of the insole body, supporting the medial arch and improving pronation. The forefoot side support pad protrudes from the front of the inner side of the insole body, gradually thinning outwards, supporting the first and second metatarsal bones and the first and second phalangeal bones of the foot, i.e., supporting the main force points when the foot pushes off the ground, guiding the forefoot to tilt outwards when the foot pushes off the ground, improving pronation. The mid-waist support pad and the forefoot side support pad work together to effectively correct in-toeing gait, with strong targeting and good effect. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] Example 1: As Figure 1-3As shown in the left insole structure, this utility model discloses an orthotic insole for inward-pointing toes, including an insole body 1, a mid-waist support pad 2, and a forefoot side support pad 3. The upper surface of the insole body 1 is the body support surface 11. The mid-waist support pad 2 protrudes from the body support surface 11 and is located in the middle of the inner side of the insole body 1. The forefoot side support pad 3 protrudes from the body support surface 11 and is located in the front of the inner side of the insole body 1. The inner side of the insole body 1 refers to the side corresponding to the inner side of the foot, which corresponds to the inner edge of the foot. The outer side of the insole body 1 refers to the side corresponding to the outer side of the foot, which corresponds to the outer edge of the foot. The front part of the insole body 1 corresponds to the forefoot, and the rear part corresponds to the heel.
[0027] The thickness of the mid-waist support pad 2 gradually decreases from the inner side to the outer side of the insole body 1. Correspondingly, its upper surface is a curved surface that gradually slopes downward from the inner side to the outer side of the foot, and the shape of the curved surface matches the contour of the medial arch. The entire mid-waist support pad 2 is higher on the inner side and lower on the outer side, which can support the medial arch, prevent the medial arch from sinking excessively, and effectively improve the phenomenon of foot pronation.
[0028] The forefoot support pad 3 provides support to one side of the forefoot. The thickness of the forefoot support pad 3 gradually decreases from the inner side to the outer side of the insole body 1. Correspondingly, its upper surface is a curved surface that gradually slopes downwards from the inner side to the outer side of the foot. The entire forefoot support pad 3 is higher on the inner side and lower on the outer side, and the size of its upper surface corresponds to the area of the first and second metatarsals and the first and second phalanges of the foot, providing support to these areas. In other words, it supports the main force-generating points when the foot pushes off the ground. Utilizing the characteristic of the forefoot support pad 3 being higher on the inner side and lower on the outer side, it guides the forefoot to tilt outwards when the foot pushes off the ground, thereby improving pronation.
[0029] In this embodiment, the width W1 of the forefoot support pad 3 is 1 / 3 to 1 / 2 of the width W2 of the insole body 1. That is, the length of the forefoot support pad 3 in the foot width direction is 1 / 3 to 1 / 2 of the length of the insole body 1 in the foot width direction. Preferably, when the width W1 of the forefoot support pad 3 is 1 / 2 of the width W2 of the insole body 1, the support and correction effect is better.
[0030] The insole body 1, midfoot support pad 2, and forefoot side support pad 3 have different hardnesses. The forefoot side support pad 3 is harder than the insole body 1, while the midfoot support pad 2's hardness falls between that of the forefoot side support pad 3 and the insole body 1. Since both the midfoot support pad 2 and the forefoot side support pad 3 are harder than the insole body 1, this hardness difference helps guide the medial arch and forefoot to tilt outwards when supporting the foot, thus providing a certain degree of correction for eversion and internal rotation. Because the first and second metatarsal bones and the first and second phalangeal bones are the main force-generating areas when the foot pushes off the ground, the corrective effect is better when the forefoot side support pad 3 is harder than the midfoot support pad 2.
[0031] In this embodiment, the Shore hardness of the insole body 1 is 38C-42C, the Shore hardness of the mid-waist support pad 2 is 45C-50C, and the Shore hardness of the forefoot side support pad 3 is 43C-52C. The insole body 1 can be made of EVA or supercritical foam material, the mid-waist support pad 2 can be made of nylon, TPU, EVA, etc., and the material of the forefoot side support pad 3 can be the same as or different from that of the insole body 1.
[0032] Preferably, when the insole body 1 is made of EVA material, its Shore hardness is 38C. When the insole body 1 is made of supercritical foam material, its Shore hardness is 40C. When the midfoot support pad 2 is made of EVA material, its Shore hardness is 40C. When the midfoot support pad 2 is made of supercritical foam material, its Shore hardness is 42C. When the forefoot support pad 3 is made of EVA material, its Shore hardness is 43C. When the insole body 1 is made of supercritical foam material, its Shore hardness is 45C. Both the midfoot support pad 2 and the forefoot support pad 3 are adhesively bonded to the main support surface 11 of the insole body 1.
[0033] The thickness of the midfoot support pad 2 near the inner side of the insole body 1 is 3-10mm, and the thickness of the midfoot support pad 2 gradually decreases to 0.2-0.5mm along the outer side and front-to-rear direction of the insole body 1. That is, the maximum thickness T1 of the midfoot support pad 2 is 3-10mm, and the minimum thickness T2 is 0.2-0.5mm. The thickness of the forefoot support pad 3 near the inner side of the insole body 1 is 2-5mm, and the thickness of the forefoot support pad 3 gradually decreases to 0.2-0.5mm along the outer side of the insole body 1. That is, the maximum thickness T3 of the forefoot support pad 3 is 2-5mm, and the minimum thickness T4 is 0.2-0.5mm. The height difference between the upper surface of the main support surface 11 and the upper surface of the forefoot support pad 3 is 0.5-3mm.
[0034] Preferably, the maximum thickness T1 of the mid-lumbar support pad 2 is 4mm, and the minimum thickness T2 is 0.5mm; the maximum thickness T3 of the forefoot side support pad 3 is 3.5mm, and the minimum thickness T4 is 0.5mm. The maximum height difference between the main support surface 11 and the upper surface of the forefoot side support pad 3 is 2mm. The curvatures of the opposite sides of the forefoot side support pad 3 and the mid-lumbar support pad 2 match, ensuring a smooth transition between them and preventing any foreign body sensation under the feet during wear.
[0035] In summary, based on the aforementioned mid-waist support pad 2 and forefoot side support pad 3, this instep orthotic insole can effectively improve problems of foot eversion and foot pronation. It is highly targeted at instep and has an excellent effect on correcting instep gait.
[0036] Example 2: Based on Example 1 above, as follows... Figure 4-5 As shown in the left shoe sole structure, this utility model also discloses an orthotic sole for pigeon toes, which includes the aforementioned orthotic insole for pigeon toes. The insole body 1 is disposed in the sole in a detachable manner or integrally formed manner. This orthotic sole for pigeon toes can effectively improve problems of foot eversion and pronation, and correct pigeon toes gait.
