Heel spurs develop most commonly among those who tend to overstress or overuse the plantar fascia ligament. Athletes who are physically very active are the ones who are highly prone to developing this condition. Overweight people and women who frequently wear high-heeled or ill-fitting shoes, are also susceptible to experiencing this problem. Middle-aged people, individuals with back pain, osteoarthritis, rheumatoid arthritis, weak calf muscles, and poor blood circulation, are also at risk of developing heel spurs.
