Welcome to the family, Swire. We're glad you've joined us. Rule Number One, don't do Too Much Too Soon (TMTS). Why is that rule number one, you might ask? Because you'll hurt yourself and have to take time off to heal, only to return to start back over at Rule Number One. Start barefoot (BF), not in minimal shoes, on hard, smooth surfaces (concrete or asphalt work just fine if you don't have a track or similar surface available); BF will help you start off right by teaching you the right form. I'd suggest running 1/4 to 1/2 mile BF on Mondays, Wednesdays and Fridays, leaving the interim days for your feet and legs to adjust, adapt and consolidate the gains you're making slowly and steadily. As you feel better and get the hang of things, add a little distance at a time, and add one of the weekend days into the mix as well. Before you know it, you'll be running several miles BF, getting odd looks like the rest of us from passers-by.
And TJ - that little revelation does clear up a lot of questions I've been pondering.
