I am very happy with these fold-up flats. They are so comfortable!! I wear a size 6 1/2, so I bought the 6 1/2 to 7 1/2 size shoe. They fit perfect. Plenty of room in the shoe. I am going to renew my wedding vows in Paris, France and I needed a flat shoe that I could wear when I am not wearing my heels for pictures. Very happy customer and I would recommend this product.
