Prim shoe design for men and women, is there a difference?

I have taken an in-world class on making shoes and also went through Natalia's excellent tutorials on her blog. (THANKS, Natalia.) Is there anything different for making men's shoes? Do the same numbers on the sliders give the same dimensions for men's and women's feet? Should I make the men's prim shoes bigger as most men are so tall? Or is it just the styling that is different?

At size 0, men's feet are slightly longer and a bit wider than women's feet. Also, it seems that size 20-30 is a more common size for men's shoes than size 0, but I've seen shoes as big as size 50. As for sizing up shoes, in my experience, the foot just doesn't scale up proportionately - it gets wider quicker than it gets longer - so I end up having to tweak the shoe a lot. Scaling down works a bit better (with the caveat that you'll run into problems if you use minimum size prims on the larger shoe) or maybe scaling up would work if one doens't build too close to the foot.

Thanks Jackal, that is exactly the info I needed.
