The present invention is designed to realize the three-dimensional ventilation passage of the insole made through the two-dimensional ventilation hole and to allow air to flow between the ventilation passage and the passage. This allows air to circulate throughout the shoe instead of unilateral air flow, and the newly created ventilation passage and the space created by the passage act like elastic springs, and firmly support the entire foot bed. It can be worn for activities that require strenuous movements by relieving shock and increasing the sense of unity of shoes and feet, and can be used easily and hygienically when wearing and washing due to the characteristics and shape of the material of the insole. In addition, by using a durable and shock-absorbing material as the bottom of the insole, by adding an anti-slip treatment, the sense of unity between shoes and feet is increased. The present invention is characterized by the above-mentioned characteristics (the three-dimensional ventilation structure itself constitutes the upper part of the insole and does not cause stimulation of the foot or slipping due to sweating even when directly contacting the foot pat and the bottom part of the insole is By integrating the shoe soles and feet more tightly without touching the bottom surface, the existing insole is completely reversed to realize a perfect air circulation and the heat emitted from the feet is discharged immediately. It doesn't accumulate moisture, so it has excellent effects on hygiene such as foot odor and athlete's foot. The present invention can be produced by including as a function of forming the sole of the shoe when making a variety of shoes regardless of the type of shoes as well as independent insoles that can be attached / detached as needed.
