Abstract: An energy harvesting system for footwear is described having a sole, heel and an upper and comprising a first gaseous bellows pump formed at the sole of the footwear with the bellows hinged forward of the sole; a second gaseous bellows pump formed at the heel of the footwear with the bellows hinged forward of the heel. A gas reservoir is mounted to the upper of the footwear in fluid communication with first and second gaseous pumps downstream of the pumps and adapted to receive the gaseous medium exiting under pressure from the pumps. An axial turbine has an output shaft mounted on the footwear upper downstream of the reservoir and adapted to receive pressurized gas from the reservoir when a predetermined pressure threshold is attained in the reservoir so as to activate the axial turbine; and an electrical generator mounted on the upper, downstream of the axial turbine and engaged with the turbine output shaft which can be engaged only when a predetermined shaft velocity threshold has been attained.
