Power generation shoes

A power generation shoe comprises an elastic bag, a cylindrical permanent magnet linear generator, a pipeline, a rectifying device, a rechargeable battery, a return mechanism, a sole and a vamp, wherein the sole and the vamp are connected with each other. In the power generation shoe, at least one elastic bag is arranged on a shoe sole and pressed by a foot of a person, and at least one cylindrical permanent magnet linear generator and a rectifying device and a rechargeable battery which are electrically connected with the cylindrical permanent magnet linear generator in sequence are arrangedin a vamp or the shoe sole; the cylindrical permanent magnet linear generator comprises a stator and a rotor, and when the elastic bag is pressed to deform, gas or liquid stored in the elastic bag drives the rotor to do linear motion through an arranged pipeline to cut magnetic induction lines. Part of energy generated when a person walks is converted into electric energy to be stored, the electric energy stored in the sh
