ST. LOUIS INSOLES Plantar Fasciitis results in irritation and swelling of the thick tissue on the bottom of the foot. The plantar fascia is the very thick band of tissue that holds up the bones on the bottom of the foot. This fascia can become inflamed, making walking difficult and very painful. HOW TO RECOGNIZE IT: A very common complaint of plantar fasciitis is pain in the bottom of the heel. Plantar fasciitis is usually worse in the morning and may improve throughout the day. By the end of the day the pain may be replaced by a dull aching that improves with rest. Most people suffering from plantar fasciitis also complain of increased heel pain after walking for a long period of time. Many ST. LOUIS Good Feet® customers tell us that Good Feet's Exerciser insoles or the Good Feet® Deluxe Maintainer insoles have been known to help relieve pain and discomfort commonly associated with plantar fasciitis and/or heel pain.
