A shoe constructed to provide exercise to a wearer while walking or jogging is provided. The shoe provides two bladders partially filled with liquid in the shoe's insole. The bladders are positioned rearward and forward and are interconnected by means of a hollow, flow resisting conduit. Heat venting is provided through fabric panels in the shoe upper, perforations in the shoe insole, metallic fibers in the shoe outsole, and vent tubes in the shoe inner sole.
