feeling the earth beneath my toes

I bought Vibram barefoot shoes about a year ago and love them.  I dislocated my cuboid (supposedly) in a half marathon I did two years ago and my podiatrist said that both of my feet are prone to this happening again.  My thought is that barefoot running -- if done properly, will help strengthen up the muscles and ligaments in my feet and help prevent this in the future.  So far so good, but MAN, does it kill my calves.  I need to remember to ease into it -- it kills me for 3 to 4 days afterwards so that I can barely workout.  It has been a while in general since I've ran, so I just need to remember to go slow.  Which is hard to do when you were wanting to do an olympic-distance triathlon that is only 6 weeks away...  eek.
