Yesterday, directly from work, I went to see and hear my son (yes, the Oldsmobile guy) play in three different small ensembles for a high school music contest. He did just fine, as he pretty much always does. He hasn't yet had the experience of crashing and burning like his Old Man has.
His first group was a brass choir. It was about 15 members, and I counted six girls. The amazing thing was, four out of the six of them were wearing heels. The trombone section in particular is about half girls, and almost all of them wear heels for dressy events. I have noted this in the past. The lone female bass trombonist was wearing boots with 3 1/2" block heels, the highest I saw that evening. His second group was a clarinet ensemble. Slim pickins there. One girl had on orange sandals with 2" block heels, and that was it. His third group was a trombone ensemble, and it was a repeat of the mixed brass group, on account of the same girls being part of both ensembles. On the way out, a flute group was assembling, and I counted four more pairs of heels. My son did not play in the flute ensemble, mainly because he really sucks at the flute. As do I. Why I own two of them, I have no idea.
In summary, it would appear that heels are not dead with GenZ. However, their appeal still appears to be limited to dress-up events. If there are a few who wear heels casually, I don't see it. Also, the heel of choice is definitely an approximately 3" block heel of substantial width, and it's usually attached to a single band across the toes sandal with a closed heel and ankle strap. Only one girl wore traditional black patent pumps with a 3" slim (not stiletto) heel, but that was the lone exception. There were a few boots, but 75% wore the block heeled sandals. Included in this post is a picture of the clarinet ensemble, mainly to show off the giant contrabass clarinet my son was playing. Many people have asked me, "What in the heck IS that thing?"
