First, you definately need to have both feet measured. Many people do not realize their feet can be two different sizes and/or widths. Also, you should shoe shop in the afternoon, after you have been walking for a while. Your feet will swell as the day goes on, you want shoes that will accomodate that change. Then, you want to stand up and walk around with the shoes. Often, shoe stores will have plush carpeting that can "fake" the comfort of a shoe. When you actually get out into the world of hard surfaces and concrete, the shoes could feel much different. Remember, you should not have to "break in" or "stretch out" shoes.
