I recently bought the Khaki amsterdam clogs in 38M. I usally wear a 37m but I read when buying clogs and closed burkis, go 1 size up, do I did. They fit good and I can wear a med weight sock with them if desired. I usally have a wide foot if that helps, also the khaki is really like a soft moss green tint. I am a burki fan and own 21 pairs of their shoes. I usually buy from QVC.com, but am glad amazon finaly started carrying them. I plan on buying 5 more pairs(clogs) this year.
