Kid’s shoes, in the grade school range, follow Men’s sizing. For example, kid’s sizes stop at size 7 followed by a Men’s 7.5.
There is an approximate one and a half size difference between Men’s and Women’s sizing. The most similar size to a Men’s size 7 is a Women’s size 8.5. Widths however, are the same between Men’s and Women’s shoes. For example if you are a D width in Men’s, you would be a D width in women’s as well.
