Not the GP but I use these[1] and they work great for workouts. They look pretty much the same on various amazon stores, temu, aliexpress, etc so I'd just get whatever is cheapest if I lose mine. I've also tried over ear hooks for the AirPods Pro but I wear glasses and it's an awkward fit.
This particular iteration doesn't seem to be available anymore - but there are many copy cats. The silicone is usually flexible enough to provide support integrity without being too irritating.
