Women's/ big kids Nike

Actually these are big kids size 4.5. I usually wear a 5.5 in kids or a 7/7.5 in women's. So I guess these would be like a 6.5 in women's. I really wanted these but they only had a size 4.5 so I bought them and wore them once for a couple hours and realized they were just a little too tight so they've just been sitting here looking pretty. Like new, really nice shoes.
