AI Technical Summary
Existing shoes lack breathability, especially as sweat and heat cannot be effectively expelled from the soles of the feet and inside the shoes, resulting in discomfort when worn.
The soft spacer plate in the sole has gaps and ventilation holes. When the foot is stepped on, the deformation of the foot expels the internal air and it is discharged through the exhaust hole. When the foot is lifted, outside air is drawn in, realizing gas circulation.
It improves the breathability of the shoes, reduces the temperature inside the shoes, enhances the wearer's comfort, and improves walking stability through anti-slip components.
