Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of shoe sole, specifically relates to a double density children's shoe sole. BACKGROUND

[0002] In order to pursue the comfort of the foot, the shoes on the market at present mostly adopt the shoe sole with low hardness and good elasticity. The shoe sole is soft and comfortable to wear, and is beneficial to reduce the discomfort of the user caused by long time standing.

[0003] However, compared with adult feet, the bones, joints and ligaments of the feet of the children of low age are in the development period, and have unique physiological characteristics. 70% of the foot bones are cartilages, the foot skin is smooth and elastic, the foot arch is flat, and the balance stability is not strong. If the shoe sole is too soft, the feet of the children cannot be supported in the shoes, the feet sway left and right, and the ankle joints and ligaments are easily damaged. Especially when the feet are subjected to strong impact force or torsional force in the intense movement, the forefoot and the hindfoot can show different movement states. With the increase of the impact force or the torsional force, when the ligaments of the foot arch and the soft tissues such as the tendons are insufficient to buffer the impact force, the foot arch is excessively deformed, and the soft tissues such as the tendons and the ligaments of the feet are strained or sprained. Therefore, the existing elastic shoe sole needs to be improved to ensure the normal growth and development of the feet of the children. CONTENT OF THE UTILITY MODEL

[0010] The bottom of the hard midsole is provided with a plurality of metatarsophalangeal flexion grooves corresponding to the forefoot of the human body.

[0011] The bottom of the rubber outsole is provided with bending grooves corresponding to the positions of the metatarsophalangeal flexion grooves.

[0012] The bottom of the rubber outsole is provided with strip-shaped anti-skid lines, and the direction of the anti-skid lines is consistent with the bending direction of the bending grooves.

[0013] The two sides of the rubber outsole are respectively provided with a plurality of arc-shaped grooves corresponding to the forefoot of the human body.

[0014] The bottom of the hard midsole is provided with an arc-shaped positioning groove corresponding to the lateral position of the foot of the human body, and the top of the rubber outsole is provided with an arc-shaped positioning block upwardly protruding corresponding to the position of the arc-shaped positioning groove, and the arc-shaped positioning block is clamped in the arc-shaped positioning groove.

[0015] The arc-shaped wrapping piece is a nylon piece, and the two sides of the arc-shaped wrapping piece are respectively provided with triangular holes.

[0016] After the above structure is adopted, the double-density children's shoe sole has the following beneficial effects:

[0017] 1. The upper layer of the shoe sole is a soft midsole, which can provide good comfort for the foot of the child, and the lower layer of the shoe sole is a hard midsole, which can provide good support for the foot of the child.

[0018] 2. The soft midsole is provided with an arc-shaped recess corresponding to the medial position of the arch of the human body, the hard midsole is provided with an arc-shaped support upwardly protruding corresponding to the position of the arc-shaped recess, the arc-shaped support is embedded in the arc-shaped recess, and the arc-shaped support provides necessary support for the arch, prevents the arch from being twisted too much, and ensures the stability and balance of the foot during movement.

[0035] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments below.

[0036] A double-density children's shoe sole, like Figs. 1-3As shown, it comprises a soft midsole 1, a hard midsole 2 and a rubber outsole 3 which are sequentially adhered from top to bottom, the hardness (Shore hardness) of the soft midsole is 40-45, such as the midsole made of ETPU, the hardness (Shore hardness) of the hard midsole is 48-52, such as the midsole made of MD material, in general, the hardness of the soft midsole 1 is less than that of the hard midsole 2, so as to enhance the softness of the whole sole, thereby being beneficial to improve the comfort of the foot of the child when standing and walking and reduce the tiredness of the foot of the child caused by the setting of the hard midsole, so that the sole can not only satisfy the supporting effect on the sole of the child, but also maintain the good comfort of the sole.

[0037] The soft midsole 1 is provided with an arc-shaped recess 11 corresponding to the medial position of the arch of the human body, and the hard midsole 2 is provided with an arc-shaped support portion 21 upwardly protruding corresponding to the position of the arc-shaped recess 11, the arc-shaped support portion 21 and the hard midsole 2 are made of the same material, the arc-shaped support portion 21 is embedded in the arc-shaped recess 11, and the relatively hard arc-shaped support portion 21 provides necessary support for the arch part to prevent the arch from being twisted too much, so that the arch area of the soft midsole 1 can simultaneously consider the support and softness, which is beneficial to better enhance the supporting effect on the sole of the child and improve the stability of the child when walking.

[0038] The soft midsole 1 is provided with an arc-shaped wrapping sheet 4 made of nylon corresponding to the heel position of the human body, the top of the arc-shaped wrapping sheet 4 is gradually inclined downward from back to front on both sides, and the middle of the arc-shaped wrapping sheet 4 is recessed downward to form a V-shaped deformation groove 41. The arc-shaped wrapping sheet 4 plays a role in wrapping and supporting the heel, protecting the heel, and the deformation groove 41 is beneficial to the deformation of the arc-shaped wrapping sheet 4 during movement, better fitting the heel.

[0039] Further, the arc-shaped wrapping sheet 4 is provided with a triangular hole 42 on each side, and the long side of each triangular hole 42 is arranged along the top edge of the arc-shaped wrapping sheet 4. Each triangular hole 42 plays a role in reducing weight.

[0040] The rubber outsole 3 is in the shape of a sheet with a hollow middle and an open rear end. The bottom of the hard midsole 2 is provided with a plurality of metatarsophalangeal flex grooves 22 corresponding to the forefoot of the human body, and the bottom of the rubber outsole 3 is provided with a bending groove 31 on each side corresponding to the position of each metatarsophalangeal flex groove 22. The bottom of the rubber outsole 3 is provided with a strip-shaped anti-skid pattern 32, and the pattern direction of the anti-skid pattern 32 is consistent with the extension direction of the bending groove 31. The two sides of the rubber outsole 3 are respectively provided with a plurality of arc-shaped grooves 33 corresponding to the forefoot of the human body. This is because the metatarsophalangeal joint part of the child's foot is also the flex position of the foot when walking, and the above-mentioned setting can help the foot to save effort when flexing and reduce the pressure of walking, which is beneficial to the growth and development of the foot.

[0041] The bottom of the hard midsole 2 is provided with an arc-shaped positioning groove 23 corresponding to the lateral position of the foot of the human body, and the top of the rubber outsole 3 is provided with an arc-shaped positioning block 34 upwardly protruding corresponding to the position of the arc-shaped positioning groove 23, and the arc-shaped positioning block 34 is clamped in the arc-shaped positioning groove 23. By arranging the arc-shaped positioning block 34, not only the positioning effect is achieved when the rubber outsole 3 is bonded with the hard midsole 2, but also the bonding between the rubber outsole 3 and the hard midsole 2 is more firm.

[0042] The above embodiments and drawings are not limited to the product shape and style of the utility model, and any appropriate changes or modifications made by any ordinary skilled person in the art shall be considered as not departing from the patent scope of the utility model.
