When I purchased these sneakers, I tried them on and right out of the box one foot was lower than the other.  I have never had this problem with any shoe in my life.  The good side is that amazon took them back for a full refund with no problem.  I didn't push my luck ordering a replacement pair in case it would just turn out the same way.  Maybe others have had no problem with them.  It could have just been this pair.  If it weren't for that issue, they otherwise were a great fit, looked terrific and very comfy.
