Boys Wide Shoes I Need A Conversion Chart For Ladies Shoe Size Into A Boys Shoe.?

I need a conversion chart for Ladies shoe size into a boys shoe.? - boys wide shoes

I need a ladies' shoe size 8.5 EE heel, but I want to buy a child, because they are larger and less expensive than women's shoes wide width. Any help would be appreciated. I worked at Wal-Mart several years ago and near the table of children's shoes had to stop, but as I said happened some time ago. Thanks
