The product and sizing are perfect! I'm usually a 9 to 9 1/2 in U.S sizing, and the size I chose works perfectly, with a little wiggle room (9.5 chosen)! They give you a height boost too which is super nice. With the zipper they are easy to get on and off compared to their original boot. The ankle height is nice too because it's fashionable but also versitile :) I haven't worn them a whole day at work yet but I will soon!
