These are really cute and kept my feet warm. I am on the borderline as far as sizing (7.5 in normal shoes) and I ordered the smaller size and they fit great with a bit of room to spare. My only complaint is that they tend to bunch up if you are doing a lot of walking. Definitely get the smaller size if you are in between sizes.
I have tall hunter boots in size 8 and bought the size large based on the size chart on the sock. They were way too bulky inside the boot and the cuff on top folded over the top of the boot past the seam. I ended up returning them and purchasing a size medium which fits the size 8 boot and foot perfectly.
