By the way, Susan, your suggestion that I get men's regular Sidis because the women's were too narrow worked great! Thank you very much for that advice. Just fyi, roguedog, I usually wear a 9 and my feet used to be medium width but have become a little wider with time and gravity. I first had a women's 42 and it turned out to be too narrow. Got a men's 42.5 on Susan O's advice, and it solved the problem.
