I usually wear a size 38 in Dansko clogs, so I purchased this patent clog in a 38.  It felt sloppy on my foot, so I re-ordered a size 37 thinking it would fit just right.  My toes were touching the end of the shoe in the 37 and it felt too snug.  I ended up keeping the 38's even though they are loose.  I just have to wear a heavier sock with them.  They are, however, very beautiful and the construction is true to the Dansko brand.  Very durable and comfortable.
