The claim that this is the softest flip flop ever is certainly true according to my experience.  And the size was good.  I bought a 39/40 for a US size 8 foot.  However, these came packaged in a plastic bag shoved in a cardboard box.  When I tried them on I found that the strap on the right foot had been twisted so that it hurt my toe badly.  I walked around the house in them for about an hour hoping ??? something.  That it might straighten out?  I kept trying to twist it back.  No luck.  If they hurt, they hurt, and I wasn't going to pay this much for something I'd end up not wearing.  I returned them, and did not try for a replacement as several reviewers had said the same thing.  Too bad the packagers do not put more effort into something like this.  They would surely have become my all time favorite shoe ever.  And since I'm in FL, I'd probably have become a lifetime buyer.  Well, I won't buy these again.  Buyer Beware!
