First let me say, I'm a Crocs mom.  I love for my 5 & 2 year old to wear them, they are easy for them to put on themselves, they are water friendly and easy to clean.  They also stand up to wear and still look nice, not easy feats with a 2 & 5 year old.  I've order crocs online from Amazon and other retailers and I can never get the sizing right, darn!
