I own multiple converse high tops and always get 0.5 size smaller than my Nike size. There was one pair, however, that I got in my actual size and it fit perfectly, so I decided to go with women's 7.5 with these white low tops. They're a little large, but I love them and they aren't critically larger than my feet which is why I didn't bother exchanging them. But 7's would probably fit perfectly :)
