Abstract
A cushioned insole for a shoe comprises a member formed of a resilient, porous material enclosed in an impervious envelope having a plurality of air inlet ports near the rear edge of its heel portion and a plurality of air outlet ports in its ball portion in the region of the toes of the wearer of the shoe. Such a construction, in addition to cushioning the foot, provides for drawing cool air into the toe region of the shoe as a result of the normal walking action.
