Fila burgundy red boots

I bought brand new for my daughter. She wears a 6 in women, but they were huge ! I wear a 7 1/2 and these are a lil big on me . I looked up size 25 as it says on the bottom of one pair of the boots, and on the other boot is says 6 1/2 .. the size 25 is an 8 1/2 . Non smoker . brand new . super cute !!!
