Love this bootie!  Only complaint is the price, very expensive.  I usually wear a 7 M ladies shoe and boot, but this brand requires a size 7-1/2 M (true for this brand in this bootie and other styles I have purchased).  Very comfy and warm and water repellent.  I walked all day in New York City this past Fall and it was cold and raining the entire day.  My feet stayed warm and dry.
