I LOVE these boots. I have very large calves and most boots do not fit around my calves. These boots are open all the way to the ankle and you can adjust how high you want them tied with the ribbons. One word of caution, these boots run HUGE I ordered a 9(which is my regular size) and they are probably too big, but they are so comfortable and I wore them all day during Thanksgiving and it didn't bother me too much. I definitely recommend ordering at least one size down. I believe that they are equal in quality to UGGS and half the price. I will either order another color of these boots or another model. I was extremely pleased with my purchase.
