I bought these boots because of the price, and because I read from reviews on other websites that the calf in these boots was really roomy (or too big, depending on your perspective).  They are perfect for me.  They go just over the knee in the front, and under the knee in the back.  I've gotten compliments from many people wearing these boots--they are great in winter with tights and a skirt.  They are a really comfortable boot.  For the money, I'm really pleased with these.
