XXSUISUIXX, my opinion is that these are fake. First off, big flag, the seller has only 3 sales, and they are all YSLs? Where in world could he/she be getting brand new YSLs (in Alabama, no less) for sale at such a cheap price? Even new YSL tributes that went on sale were not this low. It's too good to be true.
Secondly, when I look at the inside sole of the shoe, the YSL emblem looks funny (not polished), the stitching does not look even, and the leather itself is not smooth.
The bottom of my YSLs are matte leather, not shiny. And the text on the back of the shoe does not look like the text on mine.
I would pass. Others can chime in, but I don't think these are the real deal.
