Ran in "barefoot" shoes for first time

Ran 3.37 miles in my Meril Trailgloves, which are about the thinnest shoes out there, and no heel lift.  It felt alright, but my calves/ankles got a bit sore towards the end and after the run, the balls of my feet were sore.  But overall, I think it was a good first try.  I actually didn't plan on it, I just forgot to switch shoes and once I was outside I just decided to go for it.
