70's Shoes

All of the sudden I've had a serious craving for some 70's style sandals!  I just think they would look great with socks.  See the following examples:

or they look great alone, too:

Here's a photo of some legit vintage ones:

And here are the ones I would like to have!  These first two are via Urban Outfitters and are ridiculously expensive ($239 and $219)

This one is also via UO, but it's a little more reasonably priced ($88).

I really like these Lucky Brand ones ($89), but do you think they are 70's enough?  They're super comfortable! 

What do you think?  Which are your favorite?
