You made a good choice on the Vernon, my friend. The only reason I don't have them is that I just cant get them to fit right . I am a 10C and the Vernon doesn't come in a C width. I tried sizing down to a 9.5D but there wasn't enough room to wear them comfortably, so I got the Rutledge instead.
I am not 100% certain but I believe you can return/exchange shoes bought online to the B&M stores. I'm sure a more knowledgeable member will chime in on this fact, though.
