Provided is conventionally non-existent "optical equipment for shoes" which can generate electricity and emit light by action such as walking or running without using power supply. Without processing already-existing shoes, the equipment provides an electric generation unit in small space within each one of the shoes. The equipment can be mounted on any shoes detachably/attachably with the visible light emitted by the generated electricity being set toward the outside direction, i.e., a desired direction in a range from the side of the shoe to the rear thereof. The electric generation unit which is caused to generate electricity by pressure of foot stepping thereon during walking or running is formed into a flat panel shape so as to be provided in the small space within the shoe. When the pressure of foot stepping on the flat panel-shaped electric generation unit is applied, a piezoelectric body is distorted following the pressure, thereby generating electricity. A wiring member for feeding the electricity generated by the electric generation unit to the outside of the shoe is provided, and an LED is connected to the wiring member to emit light. The wiring member for feeding electricity is fixed on a desired opening or portion of the shoe with a fixture. The equipment is thus configured to be mounted on the shoe detachably/attachably.
