Men's size shoes are usually 2 foot size bigger than woman. So all you have to do is take away 2 sizes and there u go! Ex. mens: 10 - 2 = women's size 8! That simple XD! I worked in a shoe store for...
Add 1.5 to 2 sizes. For example, if I wear a women's 10, I would try a men's 8.5 or maybe 8. Mens shoes tend to run wider than women's so that may affect your size.
