I purchased the 9E (US) boot. I usually wear 9.5WW or 10W shoes. My toes came comfortably to the end of the boot without rubbing. The width in the foot area is very wide. I need to wear thick socks or my feet slip out. I can get my wide calf legs into both boots if I wear jeggings but nothing thicker will fit into the shaft. I don't use the cute clasps to make tighter...they are for looks only for me. The boots are thick and very well made, albeit a bit heavy. The soles are thick and rugged and protect my feet from stones, etc. I have worn them several times in many inches of water with no leaking. Im embarrassed to say my husband has also worn them (almost every day) to pump out our flooded walk or get the morning paper. He prefers mine to his! Follow the recommendations and get the right size...size downward. I hesitated but then I did buy smaller than my usual size and am very glad I did. If you have a really wide calf, these might not work for you...but, if you are able to wear wide calf dress boots from stores/catalogs like Lane Bryant or Woman Within, they will probably fit okay. Im very happy with these half height boots and wish I wouldve bought them years ago.
