10.5 for males in the US
You will find that a size 8 shoe will be marked as such if you are shopping for shoes in North America (Europe uses a different scale). I would describe it is slightly below the average male shoe...
37?
No, they are larger by 2 sizes. So a boy's size 6 is the same size as a girl's 8.
UK and Italian are the same they go by Eur (European). 36 eur =3 kids 37=4 kids but 3 kids equals 5 womens and 4 kids go by 6 womens.
