My 15yo is 5'2" and wears an 8.5 to 9 womens' shoe. My 12yo dd is 5'0" and wears a size 7.5 womens' shoe.
I'm 5'2 and wear a size 5.5 womens' shoe.
My 15yo keeps hoping that her big(ger) feet mean that she's not done growing yet. We shall see...but it's not like her genetics bring a lot of height to the table, yk?
(FWIW, my 15yo would, if allowed, buy size 10 shoes just so they look all clunky and feel all "comfy," unless, of course, she has to walk any distance in them).
