Description led me to believe this was a unisex slipper and listed the sizes, then the same sizes with an "M" prefix. Leading me to believe that was men's and the sizes without the "M" were women's. I even went so far as to click the product again in "my orders" to exchange them and it comes up in Amazon with Men's /Women's in the description right at the top, with selectable colors and the same confusing size drop down. So now I'm stuck with a Christmas gift for a woman needing size 7/8 and a slipper that says Men's 7/8 on the bottom and no time to exchange before Christmas. Very disappointed.
