A fluid circulating cushioned insole for a shoe includes a base panel and a top panel. A series of three cavities are molded into the panels including a heel c, an arch cavity and a metatarsal c. Three channels connect the cavities for circulating flow from the heel cavity to the arch cavity to the metatarsal cavity and back to the heel c. Each channel is equipped with a one-way flow valve constraining the fluid within the cavities and channels to uni-directional circulating flow to massage the foot during each step. The foot is also ventilated during each step by providing an open-bottomed pump cavity in the bottom surface of the base panel, which cavity is connected by at least one open-bottomed channel extending forwardly into fluid communication with a series of vent holes through the base panel. A matrix of branched channels connect each of the vent holes to the longitudinal channels. The pump cavity and various channels are closed and sealed as the shoe engages a floor surface to force air forwardly and upwardly through the vent holes to ventilate, cool and dry the wearers foot.
