I purchased this bootie in gray in the fall and I love them. They fit perfectly and are very comfortable. But when I bought the brown bootie, same size, they fit so tightly. I could barely get them on and the heel area fits tightly once I do finally get them on. It is a struggle to get them over my heel and then to get the zipper closed. Once they're on, they're comfortable, just like the gray ones, although a bit smaller. I would recommend going up a size.
