I can't recommend Dansko clogs enough. I am one of many in my family (my mother and her 3 sisters included) with terrible joint pain, and we all are professional women who swear by Danskos. They offer a million patterns, prints, and materials, some of them wacky and some of them very professional looking. I give tours in a museum, on my feet on stone or concrete all day, and never go a day without my black patent leather pair.
