I bought these for my husband, who bought a size 9 in Crocs for a different model after 2015 (it might have been leftover stock).  These were quite narrow and smaller in size.  We are unable to use them, but since we carried them over to Europe already before trying them on, it's too expensive to return.  If anyone else is buying, order a size up, and if you have wide feet or borderline then just get another model.
