For more comfortable wearing, the surface of the insole body is also provided with a cloth surface layer 5. When the shoe pad is used for walking, when the heel part of a human body is lifted, gas is sucked in the breathable cavity through the suction hole, when the heel part of the foot is grounded, the heel of the human body exerts pressure on the shock absorption memory film layer, the gas is discharged from the exhaust hole, and on the same reason, when the palm part of the foot is lifted, the gas is sucked in the breathable cavity through the suction hole, when the palm part of the foot is grounded, the heel of the human body exerts pressure on the shock absorption memory film layer, the gas in the breathable cavity is discharged from the exhaust hole, the ventilation effect is achieved through repeated circulation, the air is sucked in the cavity in the heel area and the breathable cavity in the half sole area in a crossed mode, the air circulation in the shoe can be achieved, the air permeability is greatly enhanced, meanwhile, the shock absorption breathable memory film layer is provided with an inwards.
