They rub like sandpaper!I have worn Fitflops for years and always found them so comfortable, but not this pair! The stitching onto the toe post isn't very straight, and the part that sticks out rubs like sand paper, but to the scratchy glitter of the fabric they are made from. I had to send them back and find a different pair of Fitflops which I am now very happy with. I will not buy a glitter pair again!
