Some things are cyclical and some things come to an end altogether. Corsets were considered part of daily wear for women, not just rich women, for centuries. COMPLETELY GONE. They're not coming back, other then some cheap corset lookalike for Goth girls. Same with high heels. They were in vogue for a while in the 50's to 80's, and then fell out with the masses. But even before the 50's women wore low heeled shoes for decades, so they were accustomed to wearing a sort of pump or heeled shoe already. Now it is almost completely gone, replaced by sneakers and combat boots. Even ballerinas have become rare. We live in an age where women value freedom over style and I don't see that changing. If only for the fact that you need practice to get used to walking comfortably in heels. And women aren't getting any practice anymore. So the moment some fashionistas proclaim the return of high heels, the women they are talking too don't know how to walk in them even if they wanted too. So if they get some they end up in a closet anyway. There is also no sense of self improvement among women any more. To quote youtuber Nerdrotic, it's the HERo's journey. You are perfect the way you are and once you realize that and ignore the patriarchy you become even more perfect. Why waste time improving yourself by learning to walk in heels when you are already perfect in sneakers? Unless a major cultural shift happens away from feminism I don't see high heels coming back happening.
We've had that already with the rise of the designer heel. That did not translate into more women taking up wearing high heels. Like any corset revival being restricted to semi fetish and goth circles, the rise of the designer high heel was just something for fashionistas and celebrities. I did not see one more high heel being worn because Posh Spice wore Louboutins or Taylor Swift is currently wearing them. Any desire of fan girls to emulate their heroes will fall flat on these women being unaccustomed and ill accustomed to wearing heels. Not to mention that most cannot afford designer heels and the cheap Chinese knockoffs will hurt them even more.
