I ordered this shoe in Stone in size 10 C/D, thinking that it was an American 10.  The shoes arrived very quickly, the cost was $35.98.  However, upon trying them on it was laughable how huge they were on my feet.  Privo is made by Clark's, a UK company, and I am guessing that the 10 I thought was American is actually a UK 10 - which is a 13 in America.  Amazon should inform their customers better about the sizing of this product.  Had I been aware of this, I would have ordered the American 8 that equates to the UK 10, and saved myself the $4.98 return shipping fee!!! I do not think I'll be ordering the 8 after all, because the price for that size is $89.98 - full price and only available from an Amazon merchant.
