Now there’s an alternative to expensive custom orthotics! The Plantar Fascia is the thick connective tissue that connects the balls of feet to the heel and supports the arches in your feet. Repeated stress causes inflammation and a burning or aching pain in the heel of the foot, a condition known as Plantar Fasciitis. PROFOOT’s Plantar Fasciitis orthotic is clinically proven to help relieve heel pain from plantar fasciitis.
