franx, heal and toe isn't hard. Sure it takes a while to get used to it when you first do it.
I think I started a few months into driving for the first time, watched a bunch of videos on a board (Greg's Shifting School) and practiced every time I went out. Didn't feel good for many many weeks. Lots of diving into the steering wheel and lots of slipping clutch.
A few years on and I would say I can do pretty much anything there is to be done with pedals. I'm not a racing driver and I know many others on here do the same. It's just a case of making the effort to practice in the first place.
It's hard when having size 11....
It's not used in everyday driving, very little peolple now how to use it correctly, to use it with benefit..
I might trie it some more then
(have 15 years of experience..)
