I bought my 5 year old son the Crush Glove Shoes. They are super cute and fit great. 1 week later, he was crying and complaining that there was sand in his shoe. I couldn't figure it out because when I went to dump them, nothing came out.I finally noticed that the sand had gotten underneath the insole (which you cannot remove) and had built up a mountain of sand (which you cannot get out). He cannot wear the shoes because there is a mountain of sand that makes them painful to wear and now that he's worn them, they cannot be returned. That was a huge waste of money.
