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 years. It is not that simple but close. Men have wider feet normally and some women’s shoes are designed for various widths. I just remember failing in love with a men’s pair of motorcycle boots size 5 that we couldn’t sell – lucky I am a size 7 with wide feet. ; >
