These are so comfortable, I ended up purchasing another pair right afterwards to keep in the car. I have flat feet and have never had the experience of flip flops actually supporting and seeming like they were made for me and not looking all sloped sideways. They are just really well constructed. I had a little rub from the strap between the toes the first day or so but it just needed to stretch out a little. The texture on the sole of the foot is somehow extremely satisfying and they are very flexible so it is like they really move with your feet. Sometimes I forget to take them off when I teach yoga.
