Designed to treat plantar fascitis and achilles tendonitis, but can be used to treat numerous other problems that cause plantar contracture of the foot. Light and breathable, this comfortable positioning sling holds the foot perpendicular, or slightly dorsiflexed, for passive prolonged stretching of the posterior fascial components of the lower leg and foot. Wear the sling while sitting or lying down - it is not an ambulatory device. Non-Returnable.
