I have a large foot and when I find a site that sells my size I jump on it. I just recently found Only Maker and I'm so happy at the variety of shoes in my size. I purchased the Square Toe Slip-on Flats in US15. I measured my foot and according to the size guide US15 was best for me. Well I finally received the shoes (international carrier to the United States) and the shoes are much too big. I probably should have tried a US14 which I will do after I hear from Only Maker with the procedure to return the shoes. I'm really bummed that the shoes don't fit because once again international postage can be as expensive as the price of the shoes! As I said the shoes are beautiful, quality is very good, style is just what I like so I would recommend purchasing these shoes.
