EFFECTIVENESS: 3/5

Several studies have indicated that both prefabricated and custom orthotics reduce foot and heel pain in patients with plantar fasciitis. One study suggested prefabricated orthotics were more effective than custom ones, but both provided clinically significant relief of foot pain. Another study found that about 85% of patients were happy with their results, while 15 % were dissatisfied or neutral.
