This is a great boot.  Extremely comfortable from the first moment I put it on.  No break-in required.  This boot does run VERY large.  I usually wear a size 11 (the other pair of Timberlands I own are 10.5), but with these I had to get a 9.5.  Thanks to Amazon's easy returns it wasn't a problem to try several sizes and now I have a pair of boots that I love.
