I ordered a pair of clogs from Dansko and they are the prober size, but the instep is from hell!  I spoke to a shop repair place and the guy said there (Fredrico's of Monterey, CA) that Dansko are famous for having really bad insteps.  My shoes kill my feet.  I wear them once in a while when I am not going to have to wear them too long or do any walking.  I will try to stretch them, but there is not a lot of room for stretching because too much stretching will pop the stitches they have.  My clogs are adorable.... they just kill my feet.  I plan on buying a pair without the back on them and will sell my others I bought.  Good quality shoe, but if you have any arch in your foot, be careful when ordering.  I should have ordered up one size and it would have been better.
