I bought these boots for my super active, fearless, mud puddle-jumping 19 month-old daughter.  Another review helped sell me on the product, but the name brand did, also.  They are solidly made boots and are soft/lightweight just like the Croc clogs.  My daughter wears a size 6.5 wide, and the size 6-7 fit her pretty well.  I considered buying the next size up, but I know now they would have been too large and she may have tripped while wearing them.  She doesn't trip in these shoes, they are light on her feet, and they are great for all the mud-trudging and puddle-jumping she loves to do.  Like another reviewer the holes in the sides seem odd considering water could get in them, but I think they're there simply to help younger kids pull the boots on easier.

I will buy another pair of these boots when she outgrows her current ones.  Really like them and am completely satisfied.
