This clog is great.  I have had foot problems for 30+ years and besides Birkenstocks, these shoes are the remedy for flat feet that are extra wide width.  I read the other reviews and decided to order a size 9 shoe for my 7 1/2 extra wide feet.  Good idea.  Actually, a size 9 1/2 would have been even better with socks on, but nonetheless, they are so comfortable and I wear them daily.
