As others have noted, there are several fundamental issues with the shoe.  First, the sizing is way off - too large.  I first ordered these in a half size larger than my child's shoe size, and they were way too big.  Then I ordered it 1.5 sizes smaller than my child's regular shoe size and they were OK.  Second, the insole of the shoe is not glued in very well and  on one of the shoes, came out on the first day. Perhaps Shoe Goo is a viable solution for that issue.  Third, there are no drain holes in the sole, nor along the sides, so unless you turn these upside down or lay them in the sun to dry, water just sits in the bottom of the shoe.  Not only does that compound the poor glue issue, but they start to develop a mildew odor.  Lastly, are related to the poor insoles and lack of drainage holes, any sand that gets into the shoe is hard to get out because it goes under the insole and doesn't have a good way to drain out.  Otherwise, the shoe is ok; the rubber sole and mesh material seem durable.  The draw sting closure mechanism seems good enough.  I'm not throwing them out, but I would suggest looking elsewhere for a better designed and manufactured product.
