I usually wear a size 8.5-9 (womens) and I ordered a size 9 in these boots (black). They fit well, except for the top calf area. I would say I have average legs and calves, but they were air-tight at the top of the boot. I thought that the other reviewer's complaints on this issue wouldn't affect me because I've never thought of myself as having large calves. But they were right after all.

There's no way I could've tucked my pants into the boots, which would be the purpose for me. Even with skinny jeans, they just wouldn't work.

However, the quality was top-notch and these boots are really cute. I wish they had fit more normally at the top, but alas, they did not. So I had to return them to Amazon, which really stinks!
