I can normally wear a U.S. mens size 10.  The size 10's I received fit like 10.5 or so.  There was just too much room in them.  A 9.5 would've been better.  I returned these and didn't keep them long enough to see if they'd shrink.  They do have a removeable insole.

There are shipping costs associated with returning something that doens't fit because Amazon was not responsible for the mistake.  So, plan on passing them along to someone else if they don't fit right rather than ship them back for six bucks or so. Nice footwear though.  No complaints.  They just didn't fit.
