Have a look at this it might help you understand club feet a bit better, but as David alluded to a club foot and an asymmetric foot are two completely different things. http://www.equipodiatry.com/article_flexural_deformities.htm
From what I've learned, if ever in doubt, shoe or trim as it looks, take into account work load and basic confirmation. Take it one step at a time and monitor.
I've heard you could try beveling down the outsides of the shoe. Theoretically it's supposed to make the "skirt" action more prominent and over several shoeings you should be able to see something.
I've had enough varied success to not answer that question anymore. That said, the feet themselves are rarely the issue keeping them sound IME. I don't have any problems keeping unilaterally club footed horses moving even, and I work on a lot of them. (Or maybe it's *because* I work on a lot of them. lol)
