"These boots are amazing. Nice low heel. I have wide calves, and the circumference was perfect. I was skeptical at first, but they fit beautifully. I usually wear a 6M, but went with a 6.5 for thicker socks, and I'm glad I did, so order at least a .5 size up. I bought the taupe, which is now sold out, but I'm coming back for the brown."
