At first the sandals looked lovely on my feet and simed to be comfortable. As soon as I got out and started walking, I noticed that the strap at the heel keeps falling no matter how tight I wear them. It was very annoying and stressful. I had to arrange the strap literally every minute. I have many flat sandals but I never experienced something like this. It is the way they are made. I was so happy when I ordered them because they are made of leather and the price is cheap. Now I understand why. I is sad that I couldn't return them because I weared them one day and obviously I took the tags off.
