Technical Field

[0001] The utility model belongs to the technical field of shoe soles, and particularly relates to a shock-absorbing shoe sole. Background Art

[0002] Shoes are a necessity for daily life. When the wearer's feet touch the ground during daily travel, sports, mountain climbing and other activities, a strong impact force will be generated on the feet. If the impact cannot be effectively delayed, the force will increase sharply, which will increase the risk of sports injuries. For this reason, shoes with shock-absorbing soles have appeared on the market to improve the comfort of the feet.

[0003] In the prior art, the shock-absorbing structure of the sole is usually made of EVA material and manufactured through a foaming process. Since the foamed sole contains a number of fine bubbles, although it is light in weight and comfortable to wear, the shock-absorbing structure of the sole is easily deformed after being used for too long, which affects the shock-absorbing effect of the sole and has a short lifespan. Utility Model Content

[0004] The purpose of the utility model is to provide a shock-absorbing sole in view of the above-mentioned technical problems. The first shock-absorbing hole and the second shock-absorbing hole arranged in the midsole are shuttle-shaped, so that the midsole has a shock-absorbing effect and can more effectively absorb and disperse stress, thereby reducing the deformation of the midsole when under pressure, and can also enhance the overall strength and stability of the midsole structure. Arc-shaped notches are arranged at both ends of the first shock-absorbing hole and the second shock-absorbing hole, which helps to reduce stress concentration, thereby enhancing the durability and reliability of the midsole.

[0028] An outer sole 1, on which a limiting groove 4 is provided;

[0029] The midsole 2 is arranged in the limiting groove 4, and a plurality of first shock absorbing holes 5 are arranged on the midsole 2, and a plurality of second shock absorbing holes 6 are arranged below the plurality of first shock absorbing holes 5 on the midsole 2, and the first shock absorbing holes 5 and the second shock absorbing holes 6 are arranged alternately;

[0030] An insole 3, arranged on the top of the midsole 2;

[0031] A connecting portion 7 is formed between the adjacent first shock absorbing holes 5 and second shock absorbing holes 6 . The first shock absorbing holes 5 and second shock absorbing holes 6 are both shuttle-shaped. Both ends of the first shock absorbing holes 5 and second shock absorbing holes 6 are provided with arc-shaped notches 8 .

[0032] In this technical solution, the outsole 1 can be made of an elastic material, such as TPU and rubber. The limiting groove 4 is used to accommodate the midsole 2. The outsole 1 can be formed by 3D printing technology or compression molding technology.

[0033] The midsole 2 can be made of nylon or PU, the midsole 2 can be pasted in the limiting groove 4, and the midsole 2 can be formed by 3D printing technology.

[0034] The outer sole 1 may also be a thin sheet structure, and the midsole 2 is adhered to the top of the outer sole 1, with the surface of the midsole 2 exposed to the outside.

[0035] The insole 3 can be made of a material with a sweat-absorbing effect, such as a structure made of multiple layers of cotton cloth, which can absorb foot sweat. It can also be made of a soft material, such as an insole 3 made of PU material through a foaming process, which is softer and can improve the comfort of the user's feet.

[0036] A plurality of first shock-absorbing holes 5 on the midsole 2 are arranged horizontally, and the plurality of first shock-absorbing holes 5 include multiple rows. A plurality of second shock-absorbing holes 6 on the midsole 2 are arranged horizontally, and the plurality of second shock-absorbing holes 6 include multiple rows. The second shock-absorbing holes 6 are located below the first shock-absorbing holes 5, and the second shock-absorbing holes 6 are located below between two adjacent first shock-absorbing holes 5, so that the first shock-absorbing holes 5 and the second shock-absorbing holes 6 are arranged alternately, and a connecting portion 7 is formed between adjacent first shock-absorbing holes 5 and second shock-absorbing holes 6.

[0037] The first shock-absorbing hole 5 and the second shock-absorbing hole 6 are both in a shuttle shape, and the shuttle-shaped hole is arranged horizontally, the two ends of the shuttle-shaped hole are located in the front-back direction of the midsole 2, and the two arc surfaces of the shuttle-shaped hole are located in the vertical direction of the midsole 2. The first shock-absorbing hole 5 and the second shock-absorbing hole 6 in the midsole 2 can increase the elasticity of the midsole 2, thereby playing a shock-absorbing role.

[0038] The design of the shuttle hole can provide a larger deformation space when subjected to foot pressure. Compared with round holes or holes of other shapes, the shuttle hole can more effectively absorb and disperse stress, thereby reducing the deformation of the midsole 2 when subjected to pressure.
