My husband got me a similar pair of Uggs three years ago and at the end of last winter, while walking my dog , a stick punctured them. I was devasted and convinced they were irreplaceable (bc I don't like the usual ugg style-my last pair were knit as well) until.. we found these! I was skeptical when he spent so much on my last pair three years ago but I wore then everyday and they lasted three years! These boots can be worn two ways and, contrary to the other review, I have wider calves that usually need a size up and they fit me fine either way.  Definitely worth the buy especially if they last three years again!
