Furthermore, the guard plate is made of hard TPU material.

Further, the second outsole is arranged in a U shape, and the U-shaped opening of the second outsole faces the protection sheet.

Further, the lowest position of the protection sheet is higher than the lower surfaces of the first outsole and the second outsole.

Further, the protection sheet comprises a bottom sheet and two wing sheets integrally formed on two sides of the bottom sheet, the bottom sheet is bonded to the lower surface of the arch of the midsole, and the two wing sheets are respectively bonded to the side surfaces of the midsole at the arch of the midsole.

Furthermore, two edges of the guard sheet close to the front side and the rear side of the sole are respectively provided with two concave parts, and a convex part is formed between the two concave parts on the same edge.

After the structure is adopted, the utility model relates to a can protect sole of arch of foot, it has following beneficial effect at least:

firstly, the hardness of the arch of the insole is enhanced by arranging the protection sheet, so that the deformation degree of the arch of the insole is lower than that of the front sole and the heel. When a user walks, the foot arch can be protected, and stress on the foot arch is reduced.

And secondly, the fins are attached to the side surfaces of the middle sole, so that the fins are bent upwards from the edge of the bottom plate, and the strength of the bottom plate is enhanced.

And thirdly, the protection sheet is provided with the inner concave part and the outer convex part which are matched with the shapes of the first big sole and the second big sole towards the arch of foot, so that the size of a gap at the joint of the first big sole, the second big sole and the protection sheet below the insole is reduced, and the inner concave part and the outer convex part also play a role in enabling the protection sheet to be bonded with the insole more firmly.

Compared with the prior art, the utility model discloses a protection piece of setting at the lower surface of insole arch of foot department plays the effect of protecting sole arch of foot department for when the insole is soft, reduced the motion damage risk of user's arch of foot department.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 4, the sole capable of protecting the arch of foot according to the present invention comprises a midsole 1, a first outsole 2, a second outsole 3 and a protective sheet 4; the first outsole 2 is connected to the lower surface of the front sole position of the midsole 1, and the second outsole 3 is connected to the lower surface of the heel position of the midsole 1; the protective sheet 4 is attached to the lower surface of the arch of the midsole 1 between the first outsole 2 and the second outsole 3, and the protective sheet 4 is made of a hard material with hardness higher than that of the midsole 1.

Therefore, the utility model discloses a protection piece 4 of the lower surface of setting in insole 1 arch of foot department when keeping the middle part soft gives arch of foot department holding power, forms the protection to arch of foot department, reduces the harm that the arch of foot received when being in the motion.

Preferably, the midsole 1 is made of EVA or ETPU material, so that the midsole 1 has better elasticity and shock-proof and cushioning properties.

Preferably, the first outsole 2 and the second outsole 3 are made of rubber, and anti-slip patterns 21 are formed on the lower surfaces of the first outsole 2 and the second outsole 3, so that the bottom made of rubber has good elasticity and anti-slip performance, and the friction force of the sole is increased by the closely arranged patterns with different shapes, so that the anti-slip performance is better.

Preferably, the protective sheet 4 is made of hard TPU material, so that the sole arch is kept soft and has certain hardness, and the damage to the arch of the sole during movement is reduced.

Preferably, the second outsole 3 is disposed in a U shape, and the U-shaped opening of the second outsole 3 faces the protection sheet 4, so that the U-shape of the second outsole 3 emphasizes on preventing the edge of the second outsole 3 from sliding, which can achieve a better anti-slip effect, and the hollow part in the middle of the second outsole 3 can also achieve a drainage function and can accommodate the convex part 44 of the protection sheet 4.
