Following @Harald Motz 's excellent overview.....an added benefit of barefoot running - be it actual or minimal drops/flat/no support - is taking it slowly. Easy, relaxed running - however you seek to frame it - is efficient physiologically and biomechanically with the zen qualities attached. Took me about 3 years. I am a lot lighter, 170 ish. Sure you'll have no problems. I went about it arse about face and made many mistakes along the way. You are already a relaxed runner. Took me a while to discover that is the key to it all.
