These are super comfy and it's nice to have waterproof Birkenstocks that won't get super smelly. They did kinda make squeaky sounds against my foot when I first got them... as in, if your foot suctioned them just right it would sound kinda like... er... something else. But, that has worn off a bit. I can walk without worrying most times. ;) Maybe it's just because I have a good arch? I dunno.
