I've had Dansko clogs, which are over $100 and have hard old-fashion soles which within a year wears out unevenly.  Fitflops has a footbed that miraculously keeps its shape and so COMFORTABLE. I am a true 6 1/2.  I first bought a 6 (like my summer sandals which need sizing down 1/2 size) but had to exchange for a 7, which fits a little big.  Still, I am happy to have gone up a 1/2 size.  By the way, the shoes stretch a little as you wear them. I am wearing these now with heavy socks but I am afraid they will be wide in the spring with no socks on.  Oh well. Still I am happy Fitflops fan.
