1) Indoor workouts in places where you can't actually go barefoot (like a gym) or wouldn't want to for hygiene reasons (like a gym.)
2) I'm sure they're great for a wide range of watersports, as mentioned in that review.
3) Maybe as that last final step before going to truly barefoot running.
I don't think they're intended to compete directly with VFFs, as the Filas clearly are. Just another option in a burgeoning market.
