These are the most comfortable sandals I have ever had in my life. I'm really sensitive about thong sandals because a lot of them bother my feet and  at first I was a little nervous that these might, but after wearing them for just a couple of hours I realized they were extremely comfortable! I've been wearing these now for about a week, and I still really love them. I think the soft material on the footbed is probably not waterproof, so just be sure not to wear these into the water!
