Ventilation apparatus for footwear

A ventilation apparatus including at least one flexible energy storage device (FESD), a switching unit, a pump, and a fluid diffuser is provided. The FESD flexibly conforms to varying contours of footwear. The FESD positioned at one or more locations of the footwear supplies electrical energy to the pump via the switching unit. The switching unit in communication with the FESD and the pump selectively changes modes of operation of the pump. The pump attached to the footwear pumps fluid into and exhausts fluid from a cavity of the footwear. A feed pipe of the fluid diffuser connected to the pump, within the cavity of the footwear, transfers the fluid pumped from the pump to the cavity of the footwear during a pump mode and transfers the fluid in the cavity of the footwear to an ambient environment external to the footwear during an exhaust mode for ventilating the footwear.
