I bought these boots in brown, and they are the most gorgeous boots I have ever owned!  The brown is an incredibly rich shade, so lovely.  I'm 5'11", and these go right up to my knee...my other riding boots do not, so I was really thrilled.  I read other reviews paying attention to sizing, and bought an 8.5, and they're perfect.  I can wear anything from 8 to 10, just depending on the maker and style, and I don't care what the size is if it fits; the 8.5'are just right.  I cannot believe the quality for the sale price...I'll probably buy 'em in black, too!
