They are so pretty! I wear an 8.5 and they did fit me at an 8.5 calves are loose (I do have small calves but there is still some good space and the buckles do come undone for more space) I like that the boot feels so well put together, nice and sturdy!  UPDATE: To start with the boot is beautiful but - I have now worn them minimally over the course of a few months and one is leaking HORRIBLY. They are now useless to me and I completely wasted 45.00. It feels as though the bottom someplace separated because when I step down water is instantly soaking into my socks in my boots so there is a huge gap someplace.
