TItle says it all; I'm a big fan of Rieker shoes, was excited about getting these. They are super comfy and warm because they're lined with wool (or something that looks like it). When I tried to protect them with a leather cream spray, I noted that the spray would not get in, like leather does. It would instead stay on the surface, That's when I looked at the stamps apposed on the shoe: a diamond is stamped to describe the surface (meaning synthetic material), not the usual cow hide symbol that indicates leather. Then it all made sense ! So I give it one star for false advertising and customer misleading. I would not have spent that much money if I'd known they were NOT LEATHER.
