I wear a size 7 but when I got my original order, the flip flop was too long.  I was told that a size 6 would fit better and was able to exchange it for a smaller size.  The size 6 fit perfectly and I no longer trip over the front part of the sandal.  I love OOFos. The flip flop is so comfortable and it feels like walking on squishy cushions and there is also a slight arch support too.  I was told by another customer that this model is discontinued so I am not sure what I am going to buy to replace this when I need another pair.  I really love the thicker footbed.
