I wear a size 12M womans. I was excited to see such a cute Teva sandal in my size. Well, I put them on and instantly took my foot again. Scratchy, the thong cuts.

EDIT

I kept trying with this shoe because I couldn't return it. I think this shoe has softened and stretched out to accept my foot and for my foot to accept the shoe. The height is manageable and its nice to have a thong/flip flop shoe that is more ladylike than just a flat cheaper flip flop. The straps have accomodated my foot by losening up a bit. I think these are a little like birkenstocks, takes several wearings to get them to feel good.
