The idea is to design shoes, which can tap energy generated/produced at every step while walking. At the base of the shoes a device may be fitted, which could regularly run a small dynamo while walking. The energy could be transformed into electric energy and stored in chargeable battery, which can be used as the energy source for gadgets like cellular phone or hearing aid. A small heater may also be fitted inside the shoes, which could help to keep the feet warm during acute winter. It may be fitted with small air pump, which could work with pressure of feet and help to circulate air within the shoes, thereby reduce perspiration of the feet in shoes, foul smell and risk of infection.
