The Vibram Five Fingers are some of the coolest new running shoes out there. It's about as close to running barefoot as you can get without actually going barefoot. The idea is that, since there is no cushion underneath, you will instinctively learn to land on the ball of your foot or your entire foot instead of the heel. And, if you don't, you'll be in serious pain :-)
A lot of top African runners started running barefoot (some almost their entire lives) and, if you think about it, there were no real "running" shoes until Nike came out with them during the 70's jogging craze. Before that, people either ran in sneakers or barefoot.
Well, this past Christmas, Santa (a.k.a. my wife) left me a pair of Vibram Five Fingers KSO under the Christmas tree :) Of course, I couldn't wait to try them on.
Putting them on can be a little challenging. The trick is to focus on sliding your big toe to the inside of your foot so that it slides into the toe slot. Once you do that, the rest of the toes seem to fall in line. Then, grab the rear loop and pull towards your heel and slide the back of the foot in. The velcro strap has to be in front of the foot (just leave it open). Otherwise, you can't slide your foot in.
Once you have them on, it's showtime. Try walking around the house in them and try in the lawn. You can almost feel every single rock or crevice of the yard underneath your feet. Pretty cool stuff.
I'm still learning to run in them. I'm up to about 1.3 miles every couple of days but they really make running a different experience than before. You feel like your are "closer" to the ground and more into the running. It's hard to explain. You just have to try them out.
