First I purchased my size, 11.5.  It was too small.  Next, I purchased a 12.0.  Too big! Really!  These must have been manufactured in different places.  I have always wanted a pair of GoLites.  They do feel like they would be super comfortable if they fit.  2 stars because Amazon made returning these a non-issue.  Thank you Amazon!  I buy almost all online purchases at Amazon.
