Running shoes aren't exactly cheap, so make sure you're treating them properly to extend their life. That means putting them on gently and cleaning them the right way (no washing machine!). Another simple way to keep your sneakers in good condition is to take them off when you're done running.
No matter how comfy those cushioned running shoes feel while you make your way through town, keeping them on when you're not running, wears them down faster. After a run, make sure to always change back into your everyday shoes. On that same note, remember to not use your running shoes at the gym when your workouts don't involve the treadmill.
