What is a size 5 in men shoes coberted to women size?

Size 5 in men's size is about a size 7 women's.

In most cases, to convert men's to women's sizes, you subtract 2 sizes from women's sizes to get the men's size, or add 2 sizes onto the men's to get a women's size. Unfortunately, this rule varies, so for a perfect fit, TRY ON THE SHOE before you buy it.
