Authentic balmain unicorn sneakers sz 8 male sz 9 female

The shoes authentic with the box. Worn once only. Too bog fir me. Sz 39 euro should be sz 8 female . But it is sz 8 male . 25 cm . I think it will be better ford sz 9 female. The sneakers has almost 7” heel! Pretty heavy . Has to have exact fit or very uncomfortable to wear if it is loose fit!
