I bought a pair of the original Dux, no lining, about 5 years ago.  They are blissful to put on at the end of a day spent on your feet.  A size EU 37 fits me perfectly, even with thick socks on in the winter.  So I decided to order a lined pair for our Fall air travels.  I noticed they were now marketed by Chung Shi.  Because they were lined, I ordered a &#34;38/39&#34;.  My toes and heel won't both fit in the clog!  I set it up against my original, unlined Dux, and the lined pair is 1/4&#34; shorter AND narrower.  And there was no notice in the description that they run so small.  I'm returning them to Amazon, and unfortunately Amazon is not currently carrying the lined larger size.  I do want to add that the previous reviewer did not mention the main reason to spend the money for Dux vs. Crocs -- the blissfully soft footbed that still supports your arches beautifully.  That characteristic is true of the new Dux as well as the old Dux.  They just got the sizing wrong.
