Women's Tennis Shoes

What size should I wear boots for snowboarding men if I wear A 9 - 9 1 / 2 in tennis shoes for women?

it would be a size 6 or 7, but it would be a much better idea whether you have shoes for women. if they do match you will not be happy on the mountain and it will be a bad experience.

I do not think it's a good idea because the snowboard boots to be exact if you do you can break an ankle if you fall
