I love to run in asics! I have broken a toe in the past, and I have to wear a wide running shoe for comfort. It hasn't been a problem in other asics styles, but this one was too narrow, even in a "wide" size. If it weren't for the one toe on the one foot, I'm sure the shoes would have been fine. I just received the 2170 in a wide, and my foot feels like it's home.
