These are definitely not for the slim-calved, I think they're like 15 inches circumference at size 9.  I wear a size 8 and the size 9 is perfect to wear with a good insole. They are a nice looking boot, not the highest quality, but cute and good for both casual and more dressed-up looks.  I'm 5'4" and they end right below my knee.  They are great if you don't like making a ruckus as you walk, both the heel and sole are rubber, and virtually silent when you walk, that's a real plus. If you're looking for a Frye or Canadiana quality boot, this is not it, but if you want a mid-range boot this is a good pick.
