Hey DudeUnisex-Child Wally Funk Kids Loafer

What size would a man size 12 be for this specific shoe ?

My granddaughter wears a size 6 youth what would she need in these?

What is the difference between the 10 and the 10 toddler?

Are these actually youth or are they womens? I See sizes that say the number alone then sizes with the number and a letter
