These laser shoes were designed with Parkinson's patients in mind. Conceived by Murielle Ferraye of the University of Twente in the Netherlands, the laser cue shoe is supposed to stop gait freezing and reduce symptoms for people suffering with Parkinson's disease.
The footwear is equipped with small lasers to help them maintain their balance and continue to walk normally when their illness prevents them from taking the next step. Each shoe in the pair has a laser projection device installed in the toe, emitting a red line approximately 18 inches ahead. This helps the wearer walk in a line and have something to aim for when gait freezing occurs. The laser isn't in use when the shoes are in motion and will only project when feet are resting.
