I think fit and function are what dooms the high heel industry.
Having raised six daughters almost everyone of them wore heels for the first time at their Junior Prom, a right of passage for a high schooler here in the USA anyway. But since they might grow out of them, and being for a singular event where they would only be worn for a few hours, they were all chosen entirely for how they looked with my daughter's dress. They therefore were cheap and ill-fitting. That was how they were introduced to wearing high heels and it really never got better for them. Most of the time the only time they wear high heels beyond their junior prom which was to weddings and other special occasions. Again the high heels chosen for a singular event and chosen for how they looked and not fit and comfort.
This causes many problems. The first is that they learned by experience that high heels were uncomfortable to wear. The other issue is, being chosen for how they looked and costs, properly fitting heels are hard to find. The girls went to the local shoe store where there was a crappy selection of heels to buy and none were expensive because people were not buying expensive, well-fitting heels. And when they bought them off the internet, they were bought based on style and color and not about to be sent back because they did not fit well. "It was only for one evening" was the statement made.
My wife, she is a little different. She loves high heels, but struggles to find good ones. When she does find a pair that is comfortable, she wears them exclusively, and I tended to notice these are often the most expensive ones. But the quality retail shops are closed now, and only crappy, ill-fitting ones grace the local chains that are still open.
