Looking for Answers about Vans Authentic - Women's?

If you wear a size 09.0 in a women's shoe, then you should order a size 07.5 in the women's Vans Authentic shoe. Technically, the manufacturer considers this style a 'unisexed' design, but it is made on a men's last which is a bit wider than a women's last. But the full size plus 1/2 size conversion should provide a decent fit for you.

I would have to believe you are referring to the women's Vans Authentic shoe in colorway Purple since the other colors seem to have sufficient stock for all sizes. Unfortunately, as of right now, there are no future receipts for this shoe in the color Purple. Once stock is depleted, the shoe will be no longer available to purchase.
