I went with the reviews and ordered a half size down from what I normally would.  Good advice.  These shoes are comfortable and look great.  I was worried about the bottoms being slippery.  I live in Florida and when it rains, the paint in parking lots and in crosswalks, for example, can be slippery.  They shoe bottoms are not slippery.  They have gotten slightly wet due to rain but I haven't let them get soaked.  I have already received compliments on them.  I will be ordering another pai.
