Hah, that's just what "guys" want to think.
What we are thinking is "Oh... my... Gawd!"

Take that as you will.
I'm checking out their shoes. Actually, I do that to all women...
Personally, I only secretly wish to trip a woman if she looks like she fell out of a Jersey Shore episode. Actually, I wish to trip men who look like that as well - what with their little low-cut sequin shirts and flipped hats. I never seem to notice shoes!
If a lady or a fellow is confident and poised and nice-looking without being too "fake," that's enough to usually turn my head in admiration, not jealousy! Being a ginger helps, too.
