Description

Technical Field

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

[0002] Shoes are common daily necessities in people's lives. With the improvement of material living standards, people have higher requirements for the comfort of shoes. The breathability of traditional shoes mainly depends on the material structure of the upper. Air flow is only achieved on the instep of the foot, while the foot is in close contact with the sole. The foot is prone to sweating when walking. The gap between the foot and the sole is not circulated, which is easy to breed bacteria and produce athlete's foot, affecting people's foot hygiene and low comfort of wearing shoes. Utility Model Content

[0003] The utility model provides a shock-absorbing and ventilating sole to solve the problems of poor air permeability and low comfort of the soles of existing shoes.

[0004] The utility model adopts the following technical solutions:

[0005] A shock-absorbing and ventilating shoe sole comprises a midsole, which is composed of an upper layer and a lower layer. A support sheet is provided between the upper layer and the lower layer. The composite surfaces of the upper layer and the lower layer are provided with a plurality of grooves. The grooves of the upper layer correspond to the grooves of the lower layer to form a cavity. The support sheet is provided with guide holes corresponding to the cavity. The top surface of the upper layer is provided with criss-cross exhaust grooves. The bottoms of the exhaust grooves are provided with ventilation holes corresponding to the cavities one by one.

[0006] Furthermore, the cavity is spherical or ellipsoidal, and preferably the cavity is spherical.

[0007] Furthermore, the diameter of the air holes is 1.0 to 3.0 mm, and preferably the diameter of the air holes is 1.0 mm.

[0008] Furthermore, the supporting sheet is made of TPU material.

[0009] Furthermore, the diameter of the air holes is 3.0-5.0 mm, and preferably the diameter of the air holes is 3.0 mm.

[0010] Furthermore, the materials of the upper layer and the lower layer are both EVA.

[0011] Furthermore, the composite surfaces of the upper layer and the lower layer are both provided with limiting grooves, and the supporting sheet is placed in the limiting grooves.

[0012] Furthermore, a large sole is bonded to the bottom surface of the lower layer, and the material of the large sole is rubber or GCR, and preferably the material of the large sole is rubber.

[0013] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0014] 1. A plurality of cavities are provided between the upper and lower layers of the midsole of the present application, and the upper layer is provided with ventilation holes that connect the cavities to the outside. The soles of the feet and the heels squeeze the soles alternately to cause the air in the cavities to blow toward the soles of the feet, and air flow is achieved in the gap between the soles of the feet and the soles of the shoes, so that sweat from the soles of the feet is discharged in time, keeping the soles of the feet dry and comfortable, and protecting the hygiene and health of the feet.

[0015] 2. The upper surface of the present application is provided with criss-cross exhaust grooves, which reduce the contact area between the sole of the foot and the sole of the shoe. The sole of the shoe is connected to the heel through the exhaust grooves, and the air holes are in the exhaust grooves. When a person walks, the sole of the shoe is squeezed alternately by the sole and the heel, and the exhaust grooves guide the air to flow in the front and rear directions. The sole structure has strong fluidity and good air permeability.

[0016] 3. A support sheet is sandwiched between the upper layer and the lower layer of the present application, which improves the bending strength of the sole and protects the sole from bending and breaking. The support sheet divides the cavity into two halves, and the support sheet is provided with guide holes connecting the upper and lower layers of the cavity. When squeezed, the support sheet allows the air in the upper and lower layers of the cavity to flow out step by step, which plays a buffering and shock-absorbing role, and improves the walking comfort effect.
