First and oremost make sure you stretch beforehand

Try to avoid running on concrete where possible, stick to grass and dirt trails. 'Crete doesn't absorb your shock, it passes it back up along your legs.

Try to run on a balanced surface also, jolts and shockes caused by uneven sufaces cause pain

Lastly try to run in straight lines where possible, sharp turns are often attributed to ankle problems
