What is it about our legs that so many men find attractive?

I may be overthinking this, but I would like to know what guys find attractive about our legs? I mean they are just legs. I have had some guys say (of course) that they love the smoothness and shapes as well as even when we cross them. I don't really understand this, but how do guys feel when they see legs? What kind of legs do most guys like? Just a deep thought that I was wondering about.
