Enjoyed this post very much and I wonder if you might have figured, that I'd jump right in, when I see the "magic word(s)" ;-)

Also followed the link and the results of the experiments they talk about, don't surprise me at all! Its interesting to get all the facts and I'm sure they cover a lot of the mechanisms at work.

For me the question remains, why high heels keep their appeal for me, even when the effects on the female body are not in the field of view? The sheer irresistible attraction of the clack clack sound alone? Or when the girl is sitting down, as in your first picture.. a most alluring position by the way, with the opening or closing (!) of the straps of a high heel sandal...

Or when you don't even see most of the woman at all, like in quite a few of my paintings (posting with @sean-kings permission):

What matters for me also is, that a woman's feet in high heels simply look divine and I thank you for granting a look at a selection of @steemed-open's elegant collection, which she is wearing so gracefully.
