Don't try to force your feet to point straight ahead if that isn't natural. I have size 13 and I toe-out so I am familiar with the heel hitting the crank and the stays.
I use Kneesavers.

+1 Same here. If you have natural heel-in tendency, artificially torquing your knee via straight-mount cleats to clear the crank or chainstay may damage your knee. or not. You have to figure it out. Road shoes will definitely be narrower at heel, so maybe with them you can maintain current foot angle, and miss the crank as you hope.
