An insole for a shoe is made of a resin having elasticity. The thickness of the insole increases gradually from the portion corresponding to the arch of the foot toward the heel portion to give a slope on the insole. In the bottom of the insole, corresponding to the slope, a recess is provided and ventilation holes are pierced between the recess and the upper surface of the insole. Other ventilation holes are provided through the insole in the area from a toetip to the arch of the foot portion and are connected to the recess through grooves provided in the bottom surface of the insole.
