I, along with a number of my siblings, have plantar fascitis, which is basically heal pain.

From Science Daily comes this report of a new stretch exercise which is reported to help:

The stretch requires patients to sit with one leg crossed over the other, and stretch the arch of the foot by taking one hand and pulling the toes back toward the shin for a count of 10. The exercise must be repeated 10 times, and performed at least three times a day, including before taking the first step in the morning and before standing after a prolonged period of sitting. More than 90 percent of the patients were totally satisfied or satisfied with minor reservations, and noted distinct decrease in pain and activity limitations. The most common cause of heel pain, plantar fasciitis occurs when the plantar fascia, the flat band of tissue that connects your heel bone to your toes, is strained, causing weakness, inflammation and irritation. Common in middle-aged people as well as younger people who are on their feet a lot, like athletes or soldiers, people with plantar fasciitis experience extreme pain when they stand or walk. Plantar fasciitis can be a frustrating experience, as the chronic cycle of reinjury and pain can last for up to one year. DiGiovanni likens it to pulling a hamstring, and continuing to run without proper stretching. "Walking without stretching those foot tissues is just re-injuring yourself," he said.
