I was going to say ‘people being idiots’ but Birdjaguar got an even more succint reply.
How can "people being idiots" not be more succinct?
I did my fashion-thing once. Back in the summer of 1981, the theatre group I worked with decided to enter the parade, and put on our own version of the Royal Wedding. They invited the backstage workers to take part, as we "never got to be on stage".
So for the hell of it (and my grandmother's nagging that
of course I deserved this for the years I'd put in of making and looking after props, going up and down into the rafters, helping out with other things, and only ever being a name in the crew section of the program books...)... I took part in this thing. I got dressed up in a long, lacy white dress, elbow-length white gloves, not-too-funny hat, and then had to find a pair of sandals to walk a parade route in. Oh, and I wasn't playing Diana. I was just one of the (overaged) flower girls (the real wedding used young children; we opted for older people).
So... looked through my shoes, trying to figure out which pair of white sandals would work best for walking a 3-mile parade route on asphalt. The pair of 1.5" wedge-heeled ones were the best of the lot, as I had neither the money nor the time to go out and get a new pair.
Holy crap, my feet were aching well before the parade was over. Thankfully the last few blocks had no spectators, as everyone had gone to the other good viewing spots to see it earlier. We were allowed to hop on the double-decker bus that followed us (that's where we stashed our coats and purses).
Walking the next day? HA!
I won't say it wasn't a fun experience. We won first prize for our group, and someone wrote to the Queen, including the photos. We got a nice letter back from whoever did the Queen's correspondence then, thanking us and saying that our letter and photos would be added to the archives they kept of the correspondence that the Queen received from people around the Commonwealth.
So somewhere in some royal archive, there's a photo of the bunch of us posing as the Royal Family, getting a family portrait as taken by "Lord Snowden". That bit of schtick was part of the act we did that day, that every 2-3 blocks, our "Lord Snowden" (a real photographer) would gather us all to pose for a portrait. Then we'd get back in place and resume walking the parade route. We even had a real corgi for our "Queen".
How time flies. I was only 18 then, and fresh off working backstage for 'Jesus Christ Superstar'. That's the crew they mostly approached for doing this.
As for shoes... the only time I ever wore higher-height shoes after that were for organ recitals and exams (thick heels, of course, not spike). Some pieces require a finicky style of playing the foot pedals - heel and toe. If you mess that up, you can't easily get to the next pedal in time.
Other than one SF convention (an experiment quickly abandoned due to pain; the shoes themselves were lovely to look at, but not to wear), I've never worn any sort of high heel since.
High heels hurt, narrow, pointy-toed shoes hurt, and how anyone manages them without tripping or kicking others by accident is a mystery.
