Very sad, I expected from the previous reviewers remarks, to find these boots fitting snugly in the calf.  What I never expected was that one would fit while the other would not.  I measured my calves, thinking maybe I've grown suddenly asymetrical in my leg proportions, but no.  My calves are both 14 3/4 inches around.  The boots however, are not equal in circumference.  'Right one won't zip above halfway.  Nutz!.  Sent 'em back
