Love, love, love these. Rarely can I find a shoe or sandal narrow enough but I made these work. I bought them in 39 black narrow for my 8-1/2 AA foot. I had to punch one more hole in the strap over the thick part of the foot and set the buckle near the toe on the tightest hole. They fit perfectly, are comfortable, and look fantastic. I am shocked that a waterproof substance could look almost like leather and be so versatile. I am going to buy more in other colors.
