Am super tempted to get these in grey but am a bit confused about sizing. I've read that they run small compared to regular Cons, but since I don't wear those I have no idea what that means. I am usually a 7.5-8 (I prefer the larger size for things like boots since I also add a small orthotic, which I would do here as well). However, in athletic shoes I'm generally an 8.5. So are cons sized like regular shoes or gear sneakers? My feet are narrow and low-volume but I have a bunion so I like to give it some room in front.
