The most comfortable and beautiful ones I own are satin ones, from China, with fabulous hand embroidery!
I have some with flowers, others with dragons, I pretty much collected as many as even I could justify years ago, and they wear very well, all are still in perfect shape (well, obviously the bottoms of the soles get dirty!)
I don't know if they are as easy to find as they used to be, and like everything else, I imagine finding ones made of good satin, with hand embroidery, would take even more looking, but the last time I saw any, they were being sold as "Chinese wedding shoes," so you might give that a google and see what turns up!
