(Re)learning to run

To add on to what has been said, start slow and short.  I've dealt with PF too.  I use Superfeet insoles for arch support.

Now would be a good time to incorporate form drills.  This is one that LB tends to recommend...I use it, just not often enough to improve my craptastic form.

Been through the PF wringer before, too.  And achilles tendonosis. 

Just take it slow and wear good socks.  For some reason well-supported socks makes a huge difference for my feet.

Just don't be like Phoebe:

I am old in running years....AFIB heart condition, 3 knee surgeries, 2 back surgeries, 2 stress fractures, countless other injuries.  After the last knee surgery 3 or 4 years ago I was done.  Still, I'm a runner.....I have always been a runner.  So as Fall came around this year and I approach 60 years old, I thought I'd give it another go.  It took me 6 weeks to work myself up to running a mile....I am in the middle of a 6 week plan I made to  get me to 2 miles.....my plan is a daily deal.  Once I get to two miles per day I will likely stay there, but we'll see how it goes.  Yes, my plan is painfully drawn out.....and most people who are younger with less trauma will not need anything like it.....but YOU MUST HAVE PATIENCE.  As much as the goal always seems to be running faster.....the only way to get there is to go slowly.  It's the hardest thing to learn .

riles - I've put this up before and it may be helpful to you.....these form drills are pure gold for a runner of any level.  I use them almost daily (and I already told you were I am now) and my kid is a 31:30 10K/ 15:20 5K guy and he uses them daily without fail.  You may find them helpful in getting that run "feeling" back.
