ABSTRACT:
A dynamoelectric shoe has a shoe sole that confines a watertight compartment. A pressure-operated electric generator is provided inside the watertight compartment adjacent to a heel portion of the shoe sole. The electric generator produces a voltage signal when pressure is repeatedly applied on the shoe sole during use. An electrical socket is mounted on the shoe sole and a rechargeable battery cell is wired to the electrical socket and is charged by the voltage signal from the electric generator means. The dynamoelectric shoe can be used to operate a portable wireless telephone, a portable radio, a light device to aid the user at night, or a heating device to warm the user's foot during winter.
