There is a lot of talk of calf size relating to this boot.  I have average size calves and over my jeans this boots are comfortably snug.  Recently bought a cheaper manuf. boot and cannot wear them comfortably without an insert.  These boots are comfortable as is.  I ordered a 7W and they were true to size. The heel is high enough to look good, but not so high that I don't want to walk any distance in these boots.  What I am saying is that these boots were made for walkin'.  Couldn't resist.  Love them.
