Actually, that's from an overheard conversation.
Apparently, the pick-up line "Nice shoes, let's ----" works better than you'd think and somebody asked a co-worker if that would ever work on her or anybody she knew.
She said that most women really like a cute pair of shoes so when a guy notices them, he's noticed her.
If the guy wasn't immediately creepy, it would at least start a conversation...
I've been married for quite some time now and my wife has all my attention she can stand, so I can't comment on real results, but that is what I heard.
*Ahem* now, back on topic...
