Wore it for the first time before I wrote review. I am size 8.5 in shoes/sneakers and for winter boots so I can wear super thick socks I typically go to size 9. These boots do not come in half sizes I HIGHLY recommend going a .5 size down if you are in between size. I purchased a size 8 and it still has wiggle room and the adjustable strap in the back makes getting the boot on and off easy, its also great for people of varying calf sizes. Great patterns and options from this brand and the box as other reviewers indicated is quite stylish.
