AI Technical Summary
Children and adolescents are prone to calcaneal arrhythmia and other foot deformities during toddling or walking, due to uneven force on their feet, such as flat feet and calcaneal deformities. Existing insoles cannot effectively correct these problems.
A corrected insole including the sole of the foot, the arch support and the heel part is designed. The edge of the heel part gradually becomes thinner to form a foot protection flange, the hardness decreases from the outside to the inside, and areas of different hardness are set on the sole of the foot, and bonded Fixed to form a bevel structure, composed of EVA material, to ensure that the hardness of the heel is greater than that of the arch and soles of the foot, and is used to correct the calcaneal deviation and the inner and outer eight problems.
This insole not only corrects calcaneal deviation and increases foot comfort, but also effectively corrects internal and external problems through foot protection flanges and limiting protrusions, providing better comfort and correction effects.

[0002] Insoles are widely used in the shoemaking industry, health care, and special functions. They are generally divided into two types: shoemaking application type, shoe factory application type, and market commodity type. The insoles used in the shoemaking industry are mainly made into corresponding shapes in conjunction with the outsole and midsole of the shoe, and the size plate is made according to the last plate or panel, and the corresponding shape is made.
[0003] When children learn to walk and teenagers walk, due to uneven force on their feet, they are prone to develop deformed feet (such as flat feet and calcaneal deviation). Conventional insoles cannot correct the deformed feet. Therefore, the present application proposes a corrective insole for improving calcaneal deviation, which can be used by people with calcaneal deviation foot symptoms. Utility Model Content

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.
[0021] Example
[0022] A corrective insole for improving calcaneal malalignment, such as Figure 1 and2 As shown, the insole body 1 includes a sole portion, an arch support portion 13 and a heel portion 14 which are sequentially spliced from front to back, and the edge thickness of the heel portion 14 gradually becomes thinner from outside to inside to form a foot protection flange 141 that wraps the edge of the heel.
[0023] The sole part is further divided into the lateral sole part 11 and the medial sole part 12, and at least two of the lateral sole part 11, the medial sole part 12, the arch support part 13 and the heel part 14 have different hardnesses. The sole part, the arch support part 13 and the heel part 14 respectively occupy 1 / 4-2 / 5 of the front-to-back length of the insole body 1. All parts of the insole body 1 are made of EVA material, and the hardness range of the sole part is shoreA 45 degrees-65 degrees, preferably 45 degrees, 50 degrees, 55 degrees, 60 degrees, and 65 degrees; the hardness range of the arch support part 13 is shoreA 45 degrees-70 degrees, preferably 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, and 70 degrees; the hardness range of the heel part 14 is 45 degrees-70 degrees, preferably 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, and 70 degrees.
[0024] The front end surface of the arch support part 13 and the rear end surface of the sole part are mutually fitted first inclined surfaces 15, and the two are bonded and fixed. The rear end surface of the arch support part 13 and the front end surface of the heel part 14 are mutually fitted second inclined surfaces 16, and the two are bonded and fixed.
[0025] In this embodiment, the hardness of the outer sole portion 11 and the inner sole portion 12 is different, the hardness of the outer sole portion 11 is greater than the hardness of the inner sole portion 12, and there is a third inclined surface between the outer sole portion 11 and the inner sole portion 12, and the two are bonded and fixed. The inner side of the arch portion 13 is provided with a curved surface protrusion 131 integrally formed upward.
[0026] This insole is mainly used for people with calcaneal deviation and pigeon toe symptoms. By setting a harder material on the outer side 12 of the sole, the calcaneal is corrected through the foot protection flange 141 when using this insole. In addition, since the user will feel the pain when stepping on the harder material, the foot will naturally deviate inward, thereby achieving the effect of correcting the pigeon toe symptoms.
[0027] In order to achieve a better correction effect, a limiting protrusion 17 can be set on the outer side of the inner side 12 of the sole. This is because after the limiting protrusion 17 is set on the inner side of the sole, the foot will exert force to that side after it contacts the limiting protrusion 17, thereby better achieving correction of the outward-facing toe.
[0028] In this embodiment, the hardness of the lateral sole portion 11 is the same as the hardness of the arch portion 13 .
[0029] Similarly, when people need to correct calcaneal displacement and inward-turned feet, the calcaneal bone can be corrected by setting the foot protection flange 141, and then the hardness of the outer side 11 of the sole is set to be smaller than the hardness of the inner side 12 of the sole.
[0030] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.
[0031] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
