I bought these for myself- an adult female.
I bought a few pair of the Adidas "big kid" size shoes-- they are more than half the price of womens shoes and actually fit.
I wear a 7 and sometimes 7 1/2 womens shoe. My womens Adidas that I have are all size 7 1/2.
I bought Adidas "big kid" in size 7 and they fit, they are not too narrow or too small, actually slightly bigger than the womens 7 1/2.
The only thing that I noticed was different was the shoe lace tag that is normally on the adult Adidas shoes with the logo, and the laces are not the "fat" laces that normally come with Adidas, so I purchased seperate laces.
But besides those 2 things there isn't a difference... well besides the price of course!
