My best friend says these are the most comfortable shoes he has but he wears a very small size. Even 13D, my normal size, they feel tight. I've only tested them on carpet so far. I may have to send them back. Very disappointed with the size as very soft high quality leather. They have a good insole, just wish they had a higher arch. The elastic at the top is tight. I think they are US and EU sizing and only run small, plus the high waist makes them difficult to put on and tight on the foot.
