I purchased these in a size 11 and LOVE them! I was worried the circumference would be too small for my calves, being a taller boot, but they fit just fine and there's actually room to spare. The heel placement takes a bit of getting used to, as it hits at the front of my heel when I walk vs mid/back. Otherwise they are very comfortable and I've had no issues with them needing to be broken in. The fabric is very soft and they're beautiful. A special thanks to Lauren for all of her hard work making sure I was able to purchase these in my size, and for getting them to me so quickly. She provided amazing customer service!
