I don't blame you though. Zappos is awful if you don't KNOW what you're looking for already. Shoe-store sites in the UK are much more user-friendly and browsable! But I will look into your problem (though I'm not by any means an expert in comfort shoes. My mom is on her feet all day as a teacher and she was prescribed Dansko, which are moulded-footbed clogs made in Denmark. I like Birkenstocks, too, and they have some lines that don't look like bedroom slippers now. But such shoes (a) don't really follow fashion, which is probably a good thing, and (b) are super-expensive, which is not such a good thing).
