Classic or Iconic Crocs clogs fit true to size.
The Fuzzy Crocs tend to fit small. Based on over 4,000 purchasers’ feedback:
I also found that Fuzzy Crocs felt small. If you wear a half-size US shoe normally, then choosing the next half-size-up should work fine with you. If you wear a full size, then I’d suggest you choose a shoe that’s 1 US size bigger than you normally wear.

Yes, Children's Fuzzy Crocs fit true to size.
I can not find any evidence that the Fuzzy Crocs for kids fits true to size, but I’d recommend that you choose a bigger size. Most kids' feet grow very quickly each year. If the Crocs are a little loose, they will soon fit.
That’s why I think there are little or no comments about Kids Fuzzy Crocs. Most parents (and I know I did when my kids were small) will buy a slightly larger shoe for their kids anyway.
The nice thing about Crocs is there is a strap you can pull over your ankle. This will keep the Crocs on your feet even if they are a little big.

I’ve noticed that rule of thumb with Crocs is if there is no lining, then your Crocs will fit true to size. However, if there is a lining, like with Fuzzy Crocs, or the AllCast Winter boots, then the shoe will fit a little tight.
This rain boot fits true to size
This winter boot tends to feel small. Choose half to a whole size up for a better fit.
