I bought these shoes for a young man!  He wears a men's size 9 and I was unable to get the red Bogs for men in his size.  Knowing that Bogs are sized in the universal European sizing, I simply went over to the women's side and looked for the corresponding size that he would wear.  It worked beautifully and he was so proud to get the exact boot that he wanted.  He can hardly wait for bad weather!
