I have been shopping unsuccessfully for months for a pair of wide shaft boots that don't look like they belong to my mother.  I ordered these and prepared for the worst as usuall. Don't believe the circumference listed.  These fit easily over my curvy 16" calves. They are good for shorter women as even though they are tall they don't grab the back of your knees. I am 5'3" and these are the perfect height for tall boots! Love love love! Skinnier in the ankle and a slight western look make these super awesome fantastic!
