These run on the small side. My daughter wears a size 8, but I bought the 9/10 in these and they just fit with no extra room at all. The back strap slips off her heel constantly, but she's grown quite adept at fixing it herself, and I think that's just the nature of this style of shoe. The foot bed is nice and cushy, as are the straps. I wish the back strap would stay put, then they would be perfect. The straps over the foot have not caused blisters, which is a plus when it comes to kid sandals (my girls always seem to get blisters from their sandals!). These are also very easy for my 3 yo to put on all by herself, which is another mark in their favor. All in all, I'm pretty happy with these.I read reviews saying these ran big but decided to get a 7/8 anyways (she wears an 8 shoe now). They are big but she can still walk and run in them and I figured she would have time to grow into them by the summer time when she will wear these everyday! We got the same pair last summer but got a size smaller than what she was at the time and they fit perfectly! She wore them almost everyday from May - September and they showed little wear. Never gave her any blisters and she walked, ran, played and wore them in the water! I definantly recommend them to anyone big or small who wanted high quality flip flops!These are perfect little flip flops for little feet. Bought size 5/6 and they fit her right out of the box and gave her some room to grow through the summer. She Love them, and they stay on and seem very comfortable for her. They protect her little feet and as she can pull them on easily I can guarantee she will put them on before running out of the house (don't always like her running around bare foot in the yard incase she needs to stay clean). These did the job I bought them for and did it well, with comfort for her and cute to boot.We ordered these in a size 5/6 for my daughter who wears a size 6.5. Based on prior reviews I sized down a bit and ordered the 5/6 instead of a 7/8 and I'm glad I did. These shoes fit perfectly all summer long with a little room to grow. The smaller sizes come with a back strap to help keep the little flip flops on easier. My daughter is 2.5 and these were her favorite summer shoes. Easy to get on (and off) for both us and her (just a warning!). But she liked wearing them so it wasn't a battle to keep them on her.Will order these again!My toddler and i do parent-child swim classes at the Y and I wanted her to have some water sandal type of shoe to walk through locker room/shower area to and from the pool. I was nervous about flip-flops in a two and a half year old but could not find any super-easy to put on-off water shoes or sandals, so tried these. So happy! What the photo does not show you is that at least for toddler size, there is a strap on the back so the shoe will not come off! And, it's easy enough for my daughter to put them on and take them off herself. The thong part seems comfortable and she likes them. These are our new pool shoes and we are happy!My 2 yr old daughter loves these. We tried to find the rover reefs bc they are super soft (my 6 yr old son has a pair) but couldn't. So we ordered these Ahi reefs. I think they do run a little big. My daughter has a sneaker striderites in 8 1/2 and her toes hit the end so we ordered the 9/10. There is a lot of room at the end, but the strap holds her foot on. She definitely has plenty of room to grow. The 7/8 would have prob fit her now, I'm guessing.The ones I received have an ankle strap, which I was not expecting but I like! Could easily be cut off if you don't like it. I suspect this picture is the little kids version rather than the toddler version that I bought. Seems to run big but the ankle strap keeps them on!I like this brand of flip flop, they stay on my toddler's foot and she thinks they are comfortable and easy to put on. I ordered the one pictured - white straps / pink & brown sole size 11/12. I ordered these SPECIFICALLY because of the strap on the heal. I would not have chosen this color otherwise. Well wouldn't you know it, the shoes showed up at the door WITHOUT the strap. She is doing okay without the strap in the back so far but I am still a bit irked that it is pictured with a strap. It would be nice if I was sent exactly what was shown in the picture, otherwise I would've chosen the color she really wanted.My daughter is extremely fussy about shoes, she can't bear any discomfort at all. She has worn these every day since she got them, they are very comfortable and we are very happy with them. Great price too.Really great for a kid's flop. Great reef quality, but the strap ensures they stay on.So far so good! have had these about a month - seem like they are a decent quality flip flop - my daughter really likes them and finds them to be very comfortable - can't really comment on durability at this point in time.ExcellentDaughter has lived in these all summer!
