This report describes both permanent and electromagnetic shoes for human orientation in a weightless environment. The electromagnetic shoes operate on a low voltage power source which may be adjusted to the individual requirements of the wearer. A micros witch which interrupts the magnetic circuit each time the heel is raised reduces walking fatigue and increases the .operational life of the batteries. An inertia switch is included in the magnetic circuit as a safety device. When the switch senses any sudden acceleration or deceleration, it shunts the potentiometer and allows additional current to flow to the electromagnet thereby increasing the holding force.
