Description

Technical Field

[0001] This application relates to the field of orthotic shoe technology, and in particular to an orthotic indoor shoe for children. Background Technology

[0002] Foot eversion and foot inversion are two common foot deformities in children. When children stand or walk, their feet will obviously turn outward or inward.

[0003] Eversion foot refers to a child's foot tilting outward, resulting in greater stress on the inner side of the foot and severe wear on the inner side of the shoe sole; inversion foot refers to a child's foot tilting inward, resulting in greater stress on the inner side of the foot and severe wear on the inner side of the shoe sole. Eversion / inversion foot in children may lead to ankle instability, lateral knee pain, or plantar fasciitis.

[0004] For mild cases of pronation or supination, children can use corrective shoes, braces, and other corrective tools for correction. Taking pronation as an example, the inner side of the sole of corrective shoes is usually thickened or made of a harder material, thus providing extra support to the inner side of the foot when the child is standing or walking.

[0005] However, because the insoles of orthotic shoes are relatively thin, their corrective effect on children's feet is limited. Utility Model Content

[0006] In order to improve the corrective effect of orthotic shoes, this application provides an orthotic indoor shoe for children.

[0007] This application provides a children's orthopedic indoor shoe, which adopts the following technical solution: A children's orthopedic indoor shoe includes a sole body and an upper body, the upper body being fixed to the sole body; the sole body includes a first elastic midsole and a second elastic midsole, the second elastic midsole being disposed on the first elastic midsole, the hardness of the first elastic midsole being greater than the hardness of the second elastic midsole, the first elastic midsole having a support protrusion on the side near the second elastic midsole, the second elastic midsole having a receiving groove for accommodating the support protrusion, the support protrusion being disposed on the inner or outer side of the arch portion of the sole body.

[0012] By adopting the above technical solution, when the wearer is sitting and resting, the elastic band will apply force to the wearer's feet, gradually correcting the inward tilt angle of the feet.

[0013] Optionally, the upper body includes a tongue, and the second end of the elastic band is disposed on the tongue.

[0014] By adopting the above technical solution, the second end of the elastic band is set on the shoe tongue, which can increase the force exerted by the elastic band on the foot, so as to gradually correct the inward tilt angle of the foot.

[0015] Optionally, the second end of the elastic band is disposed at the heel of the shoe upper body.

[0016] By adopting the above technical solution, the second end of the elastic band is set at the heel of the shoe upper body, which can increase the force exerted by the elastic band on the foot, so as to gradually correct the inward tilt angle of the foot.

[0017] Optionally, the second elastic insole has a mounting groove for accommodating the elastic band.

[0018] By adopting the above technical solution, the second elastic midsole has an installation groove for accommodating the elastic band, which can improve the connection strength between the elastic band and the second elastic midsole.

[0019] Optionally, the shoe also includes an insole, wherein the insole has a limiting groove on the side near the second elastic midsole, the limiting groove being used to accommodate the elastic band.

[0020] By adopting the above technical solution, the insole has a limiting groove to accommodate the elastic band, which can reduce the slippage of the elastic band and improve the corrective effect of the elastic band on the wearer's foot.

[0021] Optionally, the elastic band abuts against the sidewall of the limiting groove.

[0022] By adopting the above technical solution, the elastic band abuts against the side wall of the limiting groove to improve the limiting effect of the insole on the elastic band.

[0023] Optionally, the sole body further includes an abrasion-resistant outsole, the first elastic midsole being fixed on the abrasion-resistant outsole, the abrasion-resistant outsole being used to contact the ground.

[0024] By adopting the above technical solution, and by setting a wear-resistant outsole at the bottom of the first elastic midsole, the wear resistance of the bottom of the sole body is improved, thereby increasing the service life of the sole body.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The first elastic midsole has a higher hardness than the second elastic midsole, which gives the first elastic midsole better support performance; this also gives the outsole body area with support protrusions better support performance, providing additional support to the wearer's foot to gradually correct the angle of foot tilt and achieve the purpose of foot correction. 2.

The first elastic midsole 121 is disposed on the abrasion-resistant outsole 11, and the second elastic midsole 122 is disposed on the first elastic midsole 121.

[0035] Reference Figure 2 In this embodiment, the hardness of the first elastic midsole 121 is greater than that of the second elastic midsole 122. The first elastic midsole 121 is provided with a support protrusion 1211 on the side near the second elastic midsole 122. The second elastic midsole 122 is provided with a receiving groove 1221 for receiving the support protrusion 1211. The support protrusion 1211 is located on the inner side 13 or outer side 14 of the arch portion of the sole body 1.

[0036] In this embodiment, the abrasion-resistant outsole 11 is made of abrasion-resistant rubber to give it good abrasion resistance. The elastic midsole 12 is made of EVA material to give it good elasticity. In this embodiment, the hardness of the first elastic midsole 121 and the second elastic midsole 122 can be controlled by adjusting their formulations, foaming temperatures, etc., so that the hardness of the first elastic midsole 121 is greater than that of the second elastic midsole 122, thereby changing the support performance of a local area of ​​the sole body 1.

[0037] The implementation principle of a children's orthotic indoor shoe according to an embodiment of this application is as follows: Reference Figure 1 and Figure 2The first elastic midsole 121 has a higher hardness than the second elastic midsole 122, which makes the first elastic midsole 121 have better support performance; that is, the area of ​​the sole body 1 with the support protrusion 1211 has better support performance, which can provide additional support for the wearer's foot to gradually correct the angle of foot tilt and achieve the purpose of foot correction.
