Quality cold water fin socks for bodyboarders don't exist.

It seems like a bodyboard company would make some quality fin socks? A few make wetsuits but quality wetsuits already exist and are mass produced. The one specialized wetsuit component bodyboarders need is fin socks and no one makes one that is near as good as they could be. A 5 and 7mm sock that is fully taped/sealed and made of quality neoprene does not exist. Super niche market I guess.
