Got these for my daughter who has swim related sports. Luckily we have a crocs store near us so she was able to try on pairs before purchase (Amazon was still cheaper than the store itself).
She normally wears an 8 but it was way too tight. She had to get a size 9 which fit perfect.
So be aware the shoe may be smaller than the size indicates. If you can try some on in person before ordering I highly recommend doing so.
Other than the sizing these are just what she wanted. Waterproof makes them the perfect poolside footwear
