I bought these boots in brown last year.  I loved them so much I bought the black ones recently, in the exact same size.  I'm from the south so although it doesn't get that cold here, I do a lot of walking outdoors.  The brown ones are perfect even over very heavy socks.

Since they're the same style, I thought there would be no issue.  Unfortunately, this pair is actually tighter, and painfully so on my right foot/ankle, even with thin dress-type boot stockings.  I've read reviews where this was the case, and I understand that they loosen up with wear, but I've only been able to wear them once due to the discomfort.  I'll keep them, but I'm really not as enthusiastic about this pair.
