The size is US Women's 9.

NOT pre-owned. They were worn by a model for one day during an indoor photo shoot. After that, they were put back in the box and remained there until the photos were taken for this listing. They are in Like New condition, and being listed as "pre-owned" ONLY BECAUSE THEY WERE BRIEFLY WORN. So to be clear, they were NOT pre-owned, but only worn briefly to take photos for an ad campaign, totally indoors, for one day.
