My son wears 3.5 trainers but I prefer to buy them a little larger as he is still growing and needs a pair quite often. I have 4 and they fit great, he is very excited about his new sneakers. They are very good quality, he had a pair of blue ones from Christmas 2018 and they are in terrible condition but he doesn't want to get rid of them so I had to get them.
