Abstract (en)
[origin: US2013180023A1] An insole for a shoe is characterized by a cushioning device that circulates air between a plastic bottom layer and a soft, porous upper layer. The air is directed to designated areas of the insole via vertical apertures, which circulate air to and over the foot of a user. The bottom layer is formed with air capturing structures that when collapsed expel air that is forced through the apertures and to the surface of the user's foot. The bottom layer and the upper layer are separated by a porous middle layer that may be foam or other light weight but breathable material.
