Conversely, I think one of the reasons some people are mesmerized by en pointe is the idea of it being painful, in the moment or at least the training/practice, and the manifest dedication involved.
You have to specifically look for shoes that don't do it.
(I recommend Whitins on Amazon. $35 shoes.)
I've got massive bunions and I remember as a kid (in the '70s-80s) that shoes for my big feet seemed to come in one width no matter the length. A size 8 and a size 10 seemed to be about the same width, the 10s just looked clownishly long. It was like I was wearing canoes on my feet.
I have giant bunions which thankfully don't bother me unless I put them in the wrong shoe, then every step is a world of pain. Finally in my mid-50s I was like "Wait, what is this 'wide toebox' shoe, that sounds like just the ticket. And it absolutely was.
Pro tip: Unless you have a narrow foot, try a cheap wide toebox shoe.
Was it NPR specifically, or your local NPR affiliate?
Keep in mind that "NPR" programming often consists of actual network programming, independent works distributed by NPR, and productions from either affiliated subnetworks (e.g., "MPR", Minnesota Public Radio, PRI/PRX, APM), and in cases individual affiliate stations (WBUR, WAMU, WNYC, WHYY, KQED, KOUW, KUTX, KCRW, etc.), or other noncommercial radio networks (e.g., Pacifica). And increasingly podcasting networks.
Using NPR's site search, the most recent story focusing on a specific ballerina's injury story is from 2017, on Fresh Air (WHYY) "From Injury To Recovery, A Ballerina Fought To Retire On Her Own Terms" <https://www.npr.org/2017/07/10/536434340/from-injury-to-reco...>. It's possible that that replayed more recently. Or that you're loosely anchored in time.
There's a story more closely matching your description, though focusing on gymnastics, in USA Today, March 2026, "How two painful sports stories underscore girls' unique injury risks" <https://www.usatoday.com/story/sports/2026/03/08/girls-great...>
Good luck!
