I'm 5'10" 170-180lbs depending on what I eat or drink that week. I have large calves from a lifetime of riding a bicycle and these boots pinched me a bit. They are starting to break in nicely now. Great quality for the $$

03-05-2018 The boots are only 2 months old and have been warm less than 12x and they have an annoying pop sound every step, it drives me crazy!
