I found these were much too large when I ordered them, especially around the calf. Will's offered to cover the return postage (hence the good review after repeated emails asking me to provide one, even though I never really wore the boots). I love the jacket I bought instead!
Great boots, waterproof and very comfy, though stiff when you first get them and its a good idea to take the time to break them in, but then they last forever. They run large, i went down a size and they were still big on me, but maybe its because im not used to the uk sizing
