How it that not the point?
It was said that women wear heels for men.
I don't. I wear them because I like heels, yes I like how they look and how they make me look and work with an outfit. That is nothing to do with men and frankly it's both offensive in a gernal sense, and heterosexist to suggest that all women's in what they wear come back to men.
Yes, that was said. But, this was not a thesis, therefore not all information was included. Now that I see your interest in the topic, I will elaborate on my former remark. It is essentially a suggestion for a crude historical explanation.
1. Most men like perky butts.
2. Perky butts are sexually attractive to most people.
3. Women appear to have had, in general, a tendency to adorn themselves more richly, in particular to garner interest from - to them - sexually attractive partners. One can hypothesize that this is the result of a societal structure, where women were - in general - not allowed to work and had to rely on the income of a husband. Failure to attract such an individual would result in less pleasurable life circumstances (such as no food).
4. During this time of male dominance over females, the high heels were - along with other things - introduced to help women attract prospective life partners. I'd like to think this occurred for lesbians, and I'm sure it did, but I dare venture speculating that it was less common than women attempting to secure a stable economic arrangement through marriage to a man.
5. Although much has changed in the last 100 years or so, some aspects of clothing appears to remain. For the most part only women wear skirts. And also, for the most part, only women wear heels.
Is it fair to say that the historical reason for women and not men wearing heels might be something along those lines?
After these many years of women wearing skirts and high heels, pearls, cleavage etc for occasions when they want to look especially attractive, this has formed in many minds, the view that these attributes are attractive.
So the sexual aspect of someone choosing high heels over low, a figure slicking outfit over a bulky, is derived, not immediate. Few people think "I'm going to attract men now, that is why I will wear high heels". Of course, some do, but most of us will do so because of the way they make you feel taller, gives us a pleasurable sway or simply because we like the way we look in a mirror when wearing high heels.
Just like anything considered unusually attractive really.
