How often should I change my walking shoes?

Hello all of you walkers out there-
It is finally getting to be summer time and the weather keeps getting better everyday! This a great time to either begin your walking program or turn it up a notch. But before doing so, be sure to have a good pair of walking shoes. I get this question alot at my WalkingWorks: Ready, Set, Step Seminars and I wanted give you a friendly reminder that when it comes to walking shoes, you should be replaced every 300-500 miles or every 3 to 6 months. This will help to prevent injury and make your walking experience that much more enjoyable! So get out there and start stepping to a healthier you today!
