Havianas Espadrilles Sz 7w 6m Green NWT.  Eur 39

I am not very familiar with this brand but the United States to size says 7 W, 6m. Which makes no sense to me, they seem to be a 7w in my opinion.  Heel to toe 9.5". Please check for size if this is a brand that you know. The European shoe size is a size 39 if that helps. Never worn still have the tags on sole.
