I am normally a size 7.5 regular, and I have 14.5" muscular calves. Based on the 120 reviews I read of this boot before I ordered it, I ordered a 6.5 Wide--a major departure for me, and I was nervous. Turns out, the foot fits very well, and it's maybe even a half size still too large, but they feel great, and it may be the way they are designed to fit. As for my calves,it was a tight squeeze over my bare naked legs the first couple of times I wore them, but I was able to stuff a pair of skinny jeans in them and still get them zipped with a little shoe-horn action with my finger; they are tight but comfortable over these jeans, and they've definitely stretched out some as other reviewers have mentioned. Overall, a great boot: the footbed feels well made, the leather is very nice, the look is beautiful and classic, and I'm in love. Good luck.
