Half Fanatic #846
I can do 440 in 220 90% of running is half mental I ran half of my last race on my left foot!
I run in Vibrams so I'm not a purist. But at least running in them still makes it impossible for me to heel-strike because it would be too uncomfortable. I have a fore-to-mid foot landing but I always allow my heels to drop down for contact before lifting off again. I think this is more the form you need to try to achieve.
Barefoot and happy
