I adore these but I need wider calf circumference, alas. So they will be going to one of you equally fabulous friends! These knee high boots have a crystal embellished upper and a manmade sole. Additionally, they have a partial side zipper closure, leather footbed with textile lining, and a pointed square toe. The heel is approximately 2 inches, while the shaft is approximately 15 inches with a 17.27 inch circumference. Of note I wear an 8.5 usually but these are on the narrower side so the 9 fit my foot nicely without squeezing when I tried on.
