Love these boots. I have a skinny calf and finally found a pair boots that fit and are super big in the calf.  I am 5'9 140lbs. Wear a size 10 women's. And my calf is 35cm.  Normally my nice boots are calf fitted.  These fit great under skinny jeans and with a wool sock and the get the job done.  I can much around in swamp of a yard now and look cute.  (I bought grey with pink soles)
