Plantar fasciitis occurs when the band of tissue along the underside of your foot, called the plantar fascia, is overstretched and aggravates the attachment at the heel bone. This can cause pain with every step you take. Dr. Scholl's Plantar Fasciitis All-Day Pain Relief Orthotics provide relief by treating the source of your pain. The insoles absorb aggravating shock impact, comfort and protect your foot with added cushioning, and support your arch to prevent the plantar fascia from stretching further so it can heal.
