Just bought the next size up in this shoe for my 2 year old since we love them so much. Super cute and durable, still look great after many months and lots of playing outside. Just buy one size bigger than normal.
Got these for my 18-mo old niece. Her parents and I couldn't wait until she had big enough feet to wear fun colorful light-up sneakers. Well, she still isn't a size 6 but she will grow into them. As soon as I gave them to her she took the shoes she was wearing off (a very much preferred shoe I might add) and she had me put them on and she went stomping around my house wearing them. Even though they were still too big really to wear, she didn't slip out; they hugged well around the foot/heel. They appear to be well-made though wearing will stand the test. The colors are bright and vibrant. The light-ups work as expected. Fun, cute and well-fitting (as far as I can tell).
