I am not a fan of crocs for myself...but these are a very cute design and look cute on my 2.5 year old. Fits my toddler great - she is just moving into a size 7, and these are perfect for her. My last pair was a 6-7, so I went with an 8 at first, but they were huge. I'd say, if there aren't 2 sizes to choose from (ex. 4-5, 6-7) then I would go with their normal size.
