Maintain a healthy weight. Lose weight if you're overweight or obese to minimize stress on your plantar fascia.
Choose supportive shoes. Avoid high heels. Buy shoes with a low to moderate heel, good arch support and shock absorbency. Don't go barefoot, especially on hard surfaces.
Don't wear worn-out athletic shoes. Replace your old athletic shoes before they stop supporting and cushioning your feet. If you're a runner, buy new shoes after about 400 to 500 miles of use.
Change your sport. Try a low-impact sport, such as swimming or bicycling, instead of walking or jogging.
Apply ice. Hold a cloth-covered ice pack over the area of pain for 15 to 20 minutes three or four times a day or after activity. Or try ice massage. Freeze a water-filled paper cup and roll it over the site of discomfort for about five to seven minutes. Regular ice massage can help reduce pain and inflammation.
Stretch your arches. Simple home exercises can stretch your plantar fascia, Achilles tendon and calf muscles.
