I think they are pretty big. Normally I'm always 7 years old (women 8-8.5) and 6 years old is perfect for me. But I found the main size difference in the smaller sizes. My son is 4 years old in sneakers and eventually fitted them at 1 and 2 years old. 1 fits him almost perfectly and 2 fits but is a bit big. This is exactly what you should pay attention to when buying. I had to buy several sizes before finding the right ones so hopefully this review will save some of you from having to do the same.
