[0018] 1. The utility model sets the insole to be an airtight material. When a person steps on the midsole, gravity squeezes the sole, causing the air inside the 3D printed lattice to be discharged through the exhaust holes. The rebound force of the 3D printed lattice is then used to extract the air in the sole, thereby maintaining a dry environment for the sole and preventing the inside of the sole from becoming wet due to sweating of the person's feet. This can effectively improve the comfort level of the device.

[0019] 2. The utility model sets a second ventilation valve inside the groove and matches it with the first ventilation valve.
