Wearing supportive shoes with arch support can reduce your risk for plantar fasciitis. Replace your footwear regularly. If you are a runner, be sure to replace your shoes after about every 500 miles that you run. Always be sure to stretch your calves, achilles tendon and plantar fascia before exercising. Incorporate low-impact exercising into your routine such as swimming or biking. This will help prevent stress on your feet and legs. Staying at a healthy weight will not only improve your overall health, it may reduce your risk of plantar fasciitis.
