Your kicks will cushion for only about 200 miles, says Lance D. Barry, D.P.M., a Georgia podiatrist who has completed 21 marathons. "After 200 miles, the midsole has lost enough impact cushioning to make you more prone to heel pain and carpal tunnel-like symptoms."
Don't track miles? Pinch the sole with your thumb on the outside and fingers inside, says Richard Braver, D.P.M., a science advisor to Runner's World. If your fingers can't compress the sole, it's time for a new pair.
