What Causes Pain in the Bottom of Your Foot When You Step?

Pain in the bottom of your foot when stepping is most commonly caused by plantar fasciitis. This condition occurs when the thick band of tissue connecting your heel to your toes becomes inflamed from overuse, improper footwear, or biomechanical issues. Other frequent causes include heel spurs, stress fractures, or nerve entrapment. The pain typically feels sharp or stabbing and is often worst with your first steps in the morning or after periods of rest. Factors like being overweight, having flat feet, or wearing unsupportive shoes increase your risk significantly.
