Jean, like MPJ, I would love to know about your other boots (just saw 2 pairs in your other thread and thought of that too). I have the same calf circumference and size, and I know exactly what you mean. I've tried multiple pairs of boots recommended by people with smaller feet, and the shaft is SO much bigger on larger sizes, it's quite frustrating!
These boots look great though. They are more traditional-looking than you typically wear, but would work well for dressier outfits. I would keep if they are comfy, it seems impossible to find a good fit.
