I overpronate, so my workout shoes wear out rather quickly. Recently, I made the cardinal sin of fitness buffs and tried to wear my shoes long after they needed to be replaced. Six months later, I'm paying the price. While I'm not 100 percent positive that I have plantar fasciitis, the symptoms certainly point to it. For example, the morning after a long workout, I feel like someone is jabbing knives up my feet. A new pair of shoes and a trip to the doctor are in my near future.

Plantar fasciitis is caused by straining the ligament that supports the arch of your foot. While it's painful, plantar fasciitis doesn't need to put you on the sidelines. Some tips:

• Buy good shoes. Shoes are not something to skimp on. Look for shoes with good arch support or consider motion control shoes if you overpronate.
• Stretch. Do calf stretches and towel stretches several times a day.
  
• Avoid hard surfaces. If you're a runner or a walker, try moving your workout to an indoor track. Cement and other hard surfaces may aggravate your pain.
• Try new exercises. Swimming won't aggravate plantar fasciitis and other activities -- such as biking -- may be easier for you.
