Ordered these shoes for my two sons and they are way too big. I had to return them and go a full size down, and even so they have some room to grow. It is a great looking shoe for a water shoe and appears to be really good quality. I'll update my review once they have used them a couple of times.After reading reviews, I ordered 1 size DOWN. My 7-year-old petite daughter wears a size 12 tennis shoe. She has a pair of New Balance and Sketchers, both size 12. So I ordered her water shoes in a size 11. I like the arch in these shoes. They fit perfectly now but will not fit her next year. Heading to the Bahamas with these, we will see how they hold up.Biggest critic is my 12 year old and he found them comfortable and passed the style test. Clearly good quality too which is what I cared about. I recommend!My son likes how comfy these feel on the bottom of his feet, but they are way too big. I ordered him a 5, as he's wearing a 5 in sneakers, and his foot comes right out of the back when he walks around. Will have to order a smaller size. Just beware of the large sizing here.My kid loves them. Don’t have to worry about her feet on the beach.My son normally wears a size 4 but I read in reviews that these watershoes run large so we went down to a size 3. Length of the shoe wise he definitely could have gone down to a size 2 but wouldn’t be comfortable with the size of the ankle area. Definitely go down at least one full size.Yes, they do run large. I wear a size 9 womens and I fit into the size 6 i ordered for my 9 year old son lol. However, they are extremely comfortable and easy to slide on, unlike most water shoes which are kind of a pain to put on. I recommend ordering down a size.My son is super picky and these were a hit!!!! He loves them. They are true to size and made well.Excelentes super efectivas para la alberca y la playa, toda la familia queremos unos para nuestra próxima salida de vacacionesTodo perfectoCuanto tiempo tarda en hacer el cambio ?
