This is my 4th pair of this style Teva sandals. I have trouble with my big toe ball joint, and thong style flip flops cause it to flare up and basically is like arthritis and hurts like a mug. These sandals use more of your whole foot rather than your toe ball joint to lift them. The soles are cushy and form to your feet, you can get them wet without any nasty smells or other issues, I just can't say enough good things about these! They pretty much fit true to size. I'm a 7.5-8, and I've always gotten the 8 and they've always fit perfectly.
