I read the other reviews and proceeded with caution...I did order 1 size up & the fit perfect...right now I can't zip them because my calf is slightly too large but I'm losing weight as we speak so I'm certain by Christmas I'll be back in my Santa suit & matching with these boots! They are beautiful & better than I expected...I believe the other reviewers were a little harsh as in most boots will not fit a larger calf...these may be slightly smaller than average but I couldn't tell...I'm in love
