This shoes size chart converts women's shoe sizes from those of one country to those of another. I've used it several times myself with much success, and I've scored some great deals on shoes - although, I must admit that I wear an average shoe size, and can usually buy off the rack without any trouble.
Better Safe Than Sorry
Of course, if you want to buy shoes online, and you want the perfect fit (especially if you wear a large shoe size or wide width shoes!) you'll want to have your feet measured by a professional. Then, take those measurements and consult the manufacturer of the shoes you want to buy, and make sure you check their return policy.
