Converse Chuck Taylor All Sar Hi

Are the made by converse? Or a copy????

What does the whole b (m) stuff mean? i'm a size 9 in women and i'm trying to see which size i have to order and the whole b (m) thing is confusing

Is a 1.5 m in little kid a size 6 in womens or a 13.5 in kids a size 6 in womens ?

What does the D stand for next to the (M)?
