People of almost any age can run for exercise. It can be done virtually anywhere at minimal cost, and you do not have to be an athletic superstar to participate. Nevertheless, there are some basic guidelines you should know to help keep your running program productive, safe, and injury-free.

Your running shoes do not have to be the newest, fanciest, or most expensive. But they should fit properly and comfortably, be well cushioned, and give your feet proper support. If you run on trails, you will want to buy shoes for trail running to grip the terrain and protect your feet.

Find a local running store that does gait analysis to help you select your shoes. You will be asked to try on different running shoes. The sales person will watch how you run in different shoes to determine which ones will provide the best support for your running style.

Expect to replace your shoes every 3-6 months or 350-500 miles (563-805 kilometers). By that point, the shock absorbing ability of the shoe will have lessened. If your legs begin to get sore, they may be a sign it is time to replace your sneakers.
