These boots are SO cute and I get compliments on them a lot. I am normally a 5.5 but got the 6 to give me some room and they fit great. As far as the material I'm kinda irritated I spent the money on these. First thing they are made in china..(cheap) I wore them once and the material got scrapped off the top. They are tight at first but after wearing them a few times they were easier to put on. Last thing is the type of zipper on them is really hard to zipper up not because of calf size.
