just be careful with barefoot running. You'll read all sorts of advice, comments ... the usual internet stuff where truths become impossible to separate from the BS.
i've kind of converted but it was not easy and still to this day, i must admit running barefoot is not convenient. One must remember our toes are the worst place for injuries because of lesser blood flow and the bones are also tiny. I just found it wasn't worth the risk to hurt myself for the sake of a little coolness factor.
I do it in the grass or in sand when i take my dog for a run.
I've never managed to desensitize my feet to run on gravel, asphalt , or forest trails. Some guys do.
But i'd still like to try the Vibram 5fingers .
and my next shoes will be racing flats.
Listen to how your calf muscles will feel as you transfer from heel striking to midsole or toe striking. Personally i find midsole is the best.
check out Chi running , but their adepts are a little dogmatic for me.
