Abstract
Description
Technical Field
[0001] This application relates to the technical field of children's shoes, and particularly to a pair of children's shoes that can prevent foot deformities. Background Art
[0002] Valgus foot is a kind of foot deformity, usually caused by the contracture of the peroneal muscle group, resulting in the foot in an everted position.
[0003] When people stand, viewed from the back, the talus and the calcaneus are on the same straight line and perpendicular to the ground, which is the normal posture. For children with a tendency to valgus foot, the calcaneus deviates laterally relative to the talus, resulting in excessive pressure on the inner side of the child's foot.
[0004] The key to preventing and managing valgus foot lies in early detection and timely intervention. Parents should closely observe the gait development of their children. Once signs of valgus foot are found, they should seek medical attention for professional evaluation and treatment in a timely manner. Mild valgus foot in early childhood can be corrected by wearing corrective shoes or orthoses to guide the foot to develop in the correct direction. Utility Model Content
[0005] In order to guide the correct development of children's feet and prevent foot deformities, this application provides a pair of children's shoes that can prevent foot deformities.

[0014] By adopting the above technical solution, when the inner side of the sole body is stressed, the metal mesh bracket will undergo structural deformation and at the same time provide good corrective force for the wearer's foot.
[0015] Optionally, the sole body further includes a silica gel midsole, and the silica gel midsole is fixedly arranged on the second midsole; a plurality of anti-slip convex strips are arranged on one side of the silica gel midsole away from the second midsole, and the anti-slip convex strips are integrally formed with the silica gel midsole.
[0016] By adopting the above technical solution, there is a relatively large frictional force between the silica gel midsole and the wearer's foot. Therefore, when the wearer's foot lands, the influence of the shoe on the landing stability of the wearer's foot can be reduced, and the walking comfort of the wearer can be improved.
[0017] Optionally, the sole body further includes a rubber outsole, and the first midsole is fixedly arranged on the rubber outsole.
[0018] By adopting the above technical solution, the rubber outsole has good anti-slip performance and wear resistance, and the deformation range of the rubber outsole is relatively small, which can provide good support for the wearer's foot.
[0019] Optionally, connecting convex strips are arranged on one side of the rubber outsole close to the first midsole, and the connecting convex strips are integrally formed with the rubber outsole; a plurality of connecting convex strips are arranged, and the plurality of connecting convex strips are arranged at intervals along the direction of the rubber outsole; a connecting groove for accommodating the connecting convex strips is formed on the second midsole.
[0020] By adopting the above technical solution, through the cooperation of the connecting groove and the connecting convex strips, the bonding area between the rubber outsole and the first midsole can be increased, so as to improve the bonding strength between the rubber outsole and the first midsole and extend the service life of the children's shoes.
[0021] Optionally, along the direction away from the rubber outsole, the cross-sectional area of the connecting rib decreases.
[0022] By adopting the above technical solution, the cross-sectional area of the connecting rib decreases, so that when the wearer's foot steps on the sole body, the foreign body sensation of the wearer's foot can be reduced, and the comfort of the wearer can be improved.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0033] The following will further elaborate on this application with reference to the accompanying Figures 1-5 drawings for a more detailed description.
[0034] An embodiment of this application discloses a children's shoe that can prevent foot deformities. The children's shoe of this application is used to prevent the foot deformity of valgus foot; when a child shows signs of valgus foot, the child can correct and prevent it by wearing the children's shoe of this application, reducing the development of the child's valgus foot condition; the children's shoe of this application can guide the child's foot to develop in the correct direction and prevent foot deformities (valgus foot).
[0035] Referring to Figure 1 , the children's shoe that can prevent foot deformities includes a sole body 1 and a vamp body 2, and the vamp body 2 is fixedly arranged on the sole body 1.
[0036] Referring to Figure 1 and Figure 2 , along the direction away from the vamp body 2, the sole body 1 successively includes a silica gel midsole 11, a second midsole 12, a first midsole 13, and a rubber outsole 14. Among them, the rubber outsole 14 is used to contact the ground, and the silica gel midsole 11 is used to contact the wearer's foot.
[0037] Referring to Figure 1 and Figure 2 , the rubber outsole 14 is a rubber - material sole, so that the rubber outsole 14 has good anti - slip performance and wear - resistance performance; and the deformation range of the rubber outsole 14 is small, which can provide good support for the wearer's foot.
[0038] On one side of the rubber outsole 14 close to the first midsole 13, there is a connecting rib 141, and the connecting rib 141 is integrally formed with the rubber outsole 14. In this embodiment, there are several connecting ribs 141, and several connecting ribs 141 are arranged at intervals along the direction of the rubber outsole 14; the second midsole 12 is provided with a connecting groove 131 for accommodating the connecting rib 141, so that the first midsole 13 and the rubber outsole 14 are adhesively fixed. And along the direction away from the rubber outsole 14, the cross - sectional area of the connecting rib 141 decreases. Thus, through the cooperation of the connecting groove 131 and the connecting rib 141, the bonding area between the rubber outsole 14 and the first midsole 13 can be increased, so as to improve the bonding strength between the rubber outsole 14 and the first midsole 13 and extend the service life of the children's shoe. At the same time, several connecting ribs 141 are arranged at intervals, which can improve the structural stiffness of the rubber outsole 14, reduce the deformation of the rubber outsole 14, be beneficial to improving the grip of the rubber outsole 14 on the ground, reducing the relative sliding between the sole body 1 and the ground, and improving the safety of the wearer. And along the direction away from the rubber outsole 14, the cross - sectional area of the connecting rib 141 decreases; when the wearer's foot steps on the sole body 1, it can reduce the foreign body sensation of the wearer's foot and improve the comfort of the wearer.
[0039] Referring to Figure 2 andFigure 3 The second midsole 12 is bonded to the first midsole 13, where the hardness of the first midsole 13 is greater than that of the second midsole 12, and along the direction from the outer side 6 to the inner side 5 of the sole body 1, the thickness of the first midsole 13 increases, and the thickness of the second midsole 12 decreases. It should be noted that in the attached drawings of the specification of this application, the right side of the sole body 1 is the inner side 5 of the sole body 1, and the left side of the sole body 1 is the outer side 6 of the sole body 1.
[0040] In this embodiment, both the first midsole 13 and the second midsole 12 are made of EVA material, so that the first midsole 13 and the second midsole 12 have good resilience performance to improve the comfort of the wearer. The hardness difference between the first midsole 13 and the second midsole 12 can be achieved by foaming process, controlling the content of ethylene vinyl acetate (VA), adding foaming additives, adjusting the sole formula, etc. In this embodiment, the hardness difference between the first midsole 13 and the second midsole 12 is achieved by controlling the content of ethylene vinyl acetate (VA). In EVA material, the higher the content of VA (ethylene vinyl acetate), the lower the hardness, the smaller the density, the greater the deformation degree of the EVA material, and the weaker the supporting effect on the foot. In this embodiment, the VA (ethylene vinyl acetate) of the first midsole 13 is less than that of the second midsole 12; thus, the hardness of the first midsole 13 is greater than that of the second midsole 12, and the supporting performance of the first midsole 13 is greater than that of the second midsole 12.
[0041] Refer to Figure 3 Along the direction from the inner side 5 to the outer side 6 of the sole body 1, the thickness of the first midsole 13 decreases, and the thickness of the second midsole 12 increases; thus, along the direction from the inner side 5 to the outer side 6 of the sole body 1, the supporting effect of the sole body 1 on the wearer's foot decreases; that is, the supporting performance of the inner side 5 of the sole body 1 is greater than that of the outer side 6 of the sole body 1. Therefore, when the wearer's foot lands, the inner side 5 of the sole body 1 has a greater supporting effect on the wearer's foot, thereby providing a good corrective supporting force for the wearer's foot to prevent the wearer from having valgus foot. That is, by providing necessary support and corrective force for the wearer's foot through the inner side 5 of the sole body 1, the shape of the wearer's foot can be improved, and the wearer's foot can be prevented from developing into the outer side 6 of the foot.
[0042] At the same time, both the first midsole 13 and the second midsole 12 are made of EVA material, and the thicknesses of the first midsole 13 and the second midsole 12 change evenly; thus, the foreign body sensation of the sole body 1 can be reduced, and the comfort of the wearer can be improved.
[0043] Refer to Figure 1 and Figure 2, the silica gel midsole 11 is fixedly arranged on the second midsole 12, and a plurality of anti-slip ridges 111 are arranged on one side of the silica gel midsole 11 away from the second midsole 12, and the anti-slip ridges 111 are integrally formed with the silica gel midsole 11. The silica gel midsole 11 has the characteristics of being light and soft, thereby improving the comfort of the wearer. At the same time, the anti-slip ridges 111 on the silica gel midsole 11 increase the friction coefficient of the surface of the silica gel midsole 11 to improve the frictional force between the silica gel midsole 11 and the foot of the wearer. Since the support performances on the inner and outer sides of the sole body 1 are different, by arranging the silica gel midsole 11 on the second midsole 12; thus, when the foot of the wearer lands, the influence of the shoe on the landing stability of the foot of the wearer can be reduced, and the comfort of the wearer when walking can be improved.
[0044] Embodiment 2
[0045] The difference between this Embodiment 2 and Embodiment 1 is that:
[0046] When the tendency of the child's valgus foot is relatively obvious, the hardness of the inner side 5 of the sole body 1 can be increased to ensure the correction and prevention effect of the children's shoes.
[0047] Referring to Figure 4 , the sole body 1 further includes an embedded part, the embedded part is embedded in the inner side 5 area of the first midsole 13, and the embedded part is arranged at the heel part of the sole body 1, and the embedded part is used to provide a supporting force for the second midsole 12. In this embodiment, the embedded part is a plastic plate 3, and an installation groove 132 for accommodating the plastic plate 3 is opened on one side of the first midsole 13 close to the second midsole 12; because the hardness of the plastic plate 3 is greater than the hardness of the first midsole 13, the overall rigidity of the inner side 5 of the shoe upper body 2 is relatively large, thereby providing sufficient corrective force for the foot of the wearer.
[0048] Embodiment 3
[0049] The difference between this Embodiment 3 and Embodiment 2 is that:
[0050] Referring to Figure 5 , the embedded part is a metal mesh bracket 4, the metal mesh bracket 4 is a cylindrical structure, and the metal mesh bracket 4 is arranged along the length direction of the sole body 1. The metal mesh bracket 4 is made of stainless steel, nitinol alloy, etc. Its advantages are high strength and good supporting force. The cylindrical metal mesh bracket 4 has three-dimensionality, so when the inner side 5 of the sole body 1 is stressed, the metal mesh bracket 4 will undergo structural deformation and at the same time provide good corrective force for the foot of the wearer.
[0051] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
