A shoe pad includes air pumping elements for cooling the interior of a shoe. The pumping elements include forward pumping elements for pumping air from back to front, and backward pumping elements for pumping air from front to back. The pad includes an upper sheet attached to a lower sheet. Each pumping element includes a channel on the lower sheet covered by the upper sheet. The channel has an intake and an exhaust. Cavities are distributed along the channel. Resilient blisters on the upper sheet are aligned with the cavities on the lower sheet to define pumps. Each pump has an intake and an exhaust. Flap valves projecting down from the upper sheet are respectively positioned against the intakes of the pumps. Alignment pins projecting down from the top sheet are positioned in alignment holes on the lower sheet.
