Ugh, we bought ours from the Crocs site. We have a million pairs of Crocs, and I got the 8/9 for my 2 year old, and the 12/13 for my 4 year old, their regular sizes.

My 2 year old cried out in pain as I tried to close the back strap--it was so tight it wouldn't close and he was in pain!

My 4 year old's fit snug, and what's the point of wearing a new shoe for only 2 weeks?  I'm sending these back to Crocs, and getting the larger size from Amazon, hoping they fit. If not, then this model is too cute but fit is all bad.

I'm guessing with the specialized, thick soles, parents need to go up a size.

It was almost heartbreaking to see them love how cute the shoes are, but couldn't wear them.
