These are terrible, they dont work. I have nothing bad to say about the flipflop, very comfortable and very light weight. Such a pretty sandal. Fantastic toddler shoes! Were very pleased! I love these slippers, super comfy and soft and pretty. Your wife could probably stuff her purse in there. This was another "on the fence" item for me. The size 5. I am 4?11 135 lbs, and I ordered a size small.
