Just a curious occurrence post-patch I've noticed. Almost all of the Royal Knights in San d'Oria [S] (the ones with Royal Knight chainmail, breeches, sallet, etc.) have some new white shoes equipped now. They definitely didn't wear them before. (Perhaps they are Ebur shoes?) I was curious if any other nations had costumes change on them. Also there is one Elvaan by the chocobo stables (another Royal Knight, in fact) who has a peculiar footwear choice...

Yes. Those are Dancer AF shoes.
