Half Fanatic #846
I ran half my last race on my left foot! I don't always roll a joint, but when I do, I roll my ankle
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
