More specifically, plantar fasciitis is an inflammation of the connective tissue, called the plantar fascia; which stretches from the base of the toes, across the arch of the foot, to its insertion into the heel bone. Overpronation is the most common cause. As the foot rolls inward excessively when walking, it flattens the foot, lengthens the arch, and increases tension on the plantar fascia.
Over time, this causes inflammation. Also known as heel spur syndrome, the condition is often successfully treated with conservative measures, such as the use of anti-inflammatory medications, ice packs, stretching exercises, orthotic devices, corticosteroid injections and physical therapy.
