[0035] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Embodiment 1

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a healthy insole suitable for children or adults with normal arches, which includes a body 10, the body 10 having a forefoot portion 11, a midfoot portion 12 and a heel portion 13 arranged in sequence from front to back, the forefoot portion 11 and the midfoot portion 12 as well as the midfoot portion 12 and the heel portion 13 are integrally connected and smoothly transitioned, and there is no obvious boundary, that is, the forefoot portion 11, the midfoot portion 12 and the heel portion 13 are three parts of the same component. In addition, in this embodiment, the side of the healthy insole that is relatively close to the human arch when in use is the inner side of the shoe, and the corresponding other side is the outer side of the shoe, that is, the inner side of the shoe is the side facing the two feet when in use, and the outer side of the shoe is the side facing away from the two feet when in use, the side of the healthy insole that faces the human foot when in use is the upper side, and the corresponding other side is the lower side.

[0038] The upper surface of the forefoot portion 11 has a low-lying area or low-lying point near the midfoot portion 12, and the upper surface of the forefoot portion 11 gradually rises upward from the low-lying area or low-lying point toward the periphery of the forefoot portion 11, so that the upper surface of the forefoot portion 11 forms a concave arc surface, which can provide better cushioning capacity when used, help improve comfort when wearing, reduce pressure on blood vessels in the foot, and is less likely to feel fatigue or pain, which is beneficial to the development of children's feet. The lower surface of the forefoot portion 11 is provided with a shock-absorbing area, and the shock-absorbing area is provided with a plurality of annular grooves 14 to improve the material's absorption and decompression capacity.

[0039] The width of the forefoot portion 11 is 79-90 mm, preferably 87.4 mm, so that the sole portion has a width greater than that of a conventional insole, which can prevent the toes from being compressed, allow the foot to move more freely, ensure the normal development of the child's foot, and be more comfortable to wear.

[0040] The midfoot portion 12 is provided with an arch area 18 that matches the arch of the human foot to support the arch of the human foot. The specific structure of the arch area 18 is the same as the arch support structure of a conventional insole, and will not be described in detail here. Preferably, a support convex pad 15 is provided on the upper surface of the midfoot portion 12 at a position corresponding to the metatarsal bone of the human foot, which helps to change the local force friction of the sole and improve sports comfort.

[0041] The lower surface of the heel portion 13 is attached with a rear shock absorbing sheet 20, which is egg-shaped and arranged in the middle of the width direction of the heel portion 13, which helps to improve the comfort of the user during exercise and promote the healthy development of the foot. The rear shock absorbing sheet 20 is preferably a slow rebound shock absorbing sheet.

[0042] The lower surfaces of the midfoot 12 and the heel 13 are bonded with the same flexible support sheet 30, which covers the lower surface of the entire heel 13 and the lower surface of the entire arch area 13. It is preferably a PU sheet, which has a harderness than the body 10 and a lower air permeability than the body 10, and is used to provide a stable and flexible support for the heel and the arch of the foot, while taking into account comfort and preventing sports injuries. The flexible support sheet 30 is provided with a perforation for the rear shock-absorbing sheet 20 to be inserted, and the rear shock-absorbing sheet 20 is inserted in the perforation. The lower surface of the flexible support sheet 30 is also provided with two arc grooves 16, which are arranged along the width direction of the flexible support sheet 30, and the arc openings of the two are arranged opposite to each other, and one of the arc grooves 16 is arranged corresponding to the contour line of the arch area, which helps to improve the bending and deformation ability of both sides of the flexible support sheet 30 and improve the sports stability.

[0043] Preferably, the main body 10 is a foamed PU breathable main body, and has soft, comfortable, breathable and antibacterial functions. The upper surface of the main body 10 is provided with a skin-friendly, breathable fabric (not shown in the figure), preferably a velvet fabric. In addition, the outer periphery of the heel portion 13 is integrally connected with a side wall 17 for wrapping the human foot, one end of the side wall 17 is integrally connected with the arch area 18, and the other end extends to the midfoot portion 12. The height of the side wall 17 is 18-19 mm, preferably 18.6 mm, which can effectively improve the heel bone wrapping and increase the wearing comfort. It should be noted that in the present embodiment, the height of the side wall 17 refers to the distance between the upper side of the side wall and the corresponding position of the lower side of the flexible support sheet 30.

[0044] Embodiment 2

[0045] like Figure 3 and Figure 4 As shown, this embodiment provides a healthy insole suitable for children with mild flat feet problems, which helps to improve the flat feet problem.

[0046] The main difference between the healthy insole provided in this embodiment and that in the first embodiment is that the shape and setting position of the rear shock-absorbing plate 20 are different. In this embodiment, the rear shock-absorbing plate 20 is roughly elliptical, and the major axis of the ellipse is arranged obliquely relative to the length direction of the main body 10. Relative to the inner side of the shoe of the heel 13, the rear shock-absorbing plate 20 is closer to the outer side of the shoe of the heel 13. At the same time, the rear shock-absorbing plate 20 passes through the perforation, that is, a gap is formed between the lower surface of the rear shock-absorbing plate 20 and the lower surface of the flexible support plate 30, and the gap is preferably 0.5 mm. In this way, the phenomenon of large sole contact of flat feet can be addressed, and the pressure on the foot can be adjusted by decompressing the outer side of the calcaneus to gradually promote the formation of the arch of the foot, improve the comfort of wearing sports, and promote the healthy development of children's feet.

[0047] In order to adapt to the arch shape of mild flat feet, the arch area 18 of this embodiment is larger than that of the first embodiment, and its specific shape is the same as the arch support structure of a conventional orthopedic insole or rehabilitation insole, which will not be described in detail here. At the same time, the lower surface of the flexible support sheet 30 of this embodiment has only one arc groove 16 and one V-shaped groove 19, and the two grooves are arranged along the width direction of the flexible support sheet 30, and the two are arranged opposite to each other, wherein the arc groove 16 is arranged corresponding to the contour line of the arch area.

[0048] In addition, the thickness of the flexible support sheet 30 at the position corresponding to the arch area 18 of the present embodiment is less than the thickness at other positions of the flexible support sheet 30, that is, the thickness is reduced at the arch position, which helps to reduce pressure and ensure wearing comfort.

[0049] Embodiment 3

[0050] like Figure 5 and Figure 6 As shown, this embodiment provides a healthy insole suitable for children with moderate flat feet problems, which helps to improve the flat feet problem.

[0051] The main difference between the healthy insole provided in this embodiment and the second embodiment is that the setting position of the rear shock absorbing plate 20 is different. In this embodiment, the rear shock absorbing plate 20 is equivalent to the outer side of the shoe closer to the heel 13 in the second embodiment, and is generally located between the midline of the heel 13 in the width direction and the outer side of the shoe.

[0052] In addition, in this embodiment, the thickness of the inner side of the heel portion 13 is 0.5-1.5 mm thicker than the thickness of the outer side of the shoe, preferably 1 mm, which helps to strengthen and improve the formation and development of flat arches. Specifically, the thickness of the heel portion 13 can gradually decrease from the inner side to the outer side of the shoe.

[0053] Embodiment 4

[0054] like Figure 7 and Figure 8 As shown, this embodiment provides a healthy insole suitable for children with high arch problems, which helps to improve the high arch problem.

[0055] The main difference between the healthy insole provided by this embodiment and the embodiment 1 is that the flexible support sheet 30 is not provided in this embodiment, the rear shock-absorbing sheet 20 is embedded in the heel portion 13, and the forefoot portion 11 of this embodiment is not provided with a shock-absorbing area, but a front shock-absorbing sheet 40 is embedded on the lower surface of the forefoot portion 11. This is a decompression design for the characteristics of high arch users who need to withstand high pressure in front and behind the arch when using it. It can effectively relieve the fatigue of high arched feet and improve the comfort of wearing sports.

[0056] In addition, in the present embodiment, the thickness of the body 10 at the arch area 18 is greater than that at other locations, so as to provide better support for the arch of the foot.

[0057] The present invention is described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the prior art, all of which belong to the protection scope of the present invention.
