Thing is, women say that they support and want to see men in heels and other feminine clothing, but for themselves they want a masculine dude. Listen to what they do, never what they say. Also, the whole crossdressing part is part of the LGHDTV brigade. And they are not making themselves popular with the majority of people. Better to stay away from lest we get tainted when the backlash against the LGHDTV brigade will happen. Although at the moment, if you are a white dude and want to get a job you now vastly increase your chances of getting hired showing up at the job interview wearing heels then in regular attire. After all, male and pale is stale, is now the mantra.
Fashion is cyclical, and some things have fallen completely out of the public mind. Like corsets. Other then a minor resurgence where a small group of people will embrace them I don't EVER see them coming back in general fashion. And so will high heels. Women will still covet them, may want to own a couple of pairs, but most will never bother to learn how to wear them so it will be going out to an occasion and then sit down ASAP wear. And I think the professions where women used to be required to wear them, like in law, are under pressure to do away with this custom of the 'patriarchy'.
