Zero G AFO Info for Medical Professionals

The Zero G ankle foot orthosis (AFO) is a prefabricated, offloading brace that relieves plantar surface pressure from the foot. The Zero G AFO incorporates a supple, but strong, adjustable, calf corset with leather lacers and Velcro closures. This design provides a total-contact, hydrostatic lift of the inverted cone shape of the calf, providing up to 100 percent offloading of the foot. The Zero G brace’s patented design, with malleable metal uprights, provides a sturdy, stable substructure that transfers weight from the ground to the calf and not the foot and ankle, providing up to 100 percent non-weight bearing.
