Crocs sizing

[RamblingRosa]

I'm thinking about getting a pair of Crocs wellies for DD. I've never bought Crocs before so not sure how the sizing comes up. Any idea if they're big or small? Also, any feedback on whether their wellies are any good would be appreciated.
Thanks

Big fan of crocs shoes (shoot me now!) and the sizing is pretty spot on if you make sure you read the english side not the american ones (eg I wear a size 5-7 IIRC that's a UK 5 and an american ladies 7).

However did try the wellies and thought they were quite hard/likely to rub my legs.

See what you think. They'll be sweaty as any wellies are.

Have you looked at the crocs boots with a solid "clog" foot and fabric leg? If you are thinking bad weather rather than wading in puddles they might be better?
