There’s more to Running than meets the eye. Just as some folks enjoy Trail Running, Cross Country, Long Distance and so on, there is a school of runners who enjoy running barefoot.
I guess some folks really do run barefoot but if you’re not sure or don’t have the feet for it you can always grab a pair of “Vibram Five Fingers” shown here.
These are probably the strangest looking things I’ve seen, like gloves for your feet. I guess that makes traditional sneakers more like mittens for your feet.
These things seems to be fairly popular and a well developed product and I’m told they have to be broken in. Check ’em out here: Vibram FiveFingers: Sprint-Male.
