MD... I would think that if those shoes are a radical adjustment, you're going to need to ease into them just as you would with orthotics or barefoot running. Half a mile to start with... What I've been doing with barefooting is doing a little at the end of some of my shod runs or on active rest days.
So, should I step back from the 2.5 miles I'm doing and start over?
I'd rather be swimming...biking...running...and eating cheesecake...
