I really wanted to be able to keep these boots.  I have never found a pair that fit properly.  I had high hopes for these.  Ironically, the calf fit well, which is usually where I have the most trouble.  The part that didn't fit this time was the ankle.  There was way too much room and though my calf kept the boot in place, my ankle felt like the inside of a big bell.  Sadly, I will have to return them.
