This isn't an easy blog to write since I can't pretend to be an expert on something I've never tried! Yet it's a hot topic in the running community so I will provide a couple of resources that give an outside perspective. Here are the pros and cons according to about.com and a shoe expert.
Personally I would like to try it; I'm curious! Yet I'm not quite ready to trade in my trusty shoes and "fix what isn't broken" for me. I do have friends that swear by their newfound love of barefoot. Most of these choose the vibram 5 fingers vs. actually going barefoot.
Shoes or no shoes, happy running feet these last few weeks as we prepare for the big day!
