After reading the book Born to Run I have been wanting to try the Vibram Five Fingers shoes. In the book they talk about how much better it is to run barefoot. It's better for your posture, back, joints, and feet. I had a foot injury a few months ago so I thought I would give them a try. I ended up purchasing the Bakila LS for running.
The Vibram Five Fingers (VFF's) are minimalist shoes. It is comparable to running barefoot but they have traction and rubber protection for your feet. They are extremely comfortable. I wear five finger socks with them to prevent any blistering.
While running in these shoes, you have to run on the balls of your feet, not your heels. So, it takes a little while to get used to. You have to work up to running this way, ball-heel-ball-heel. Your shins and calves will be sore afterwards. Think about it...you're working other muscles you're not used to using during running. After running in these the first time my calves hurt for about a week! These shoes do not add support so you have to watch where you are running. I did a couple trail runs and stubbed my toe a few times. My ankles were also sore afterwards because there is ZERO ankle support. The more I run in VFF's, the stronger my ankles, calves, and shins will be. VFF's are really flexible. Using VFF's are less painful than running completely barefoot. I tried running barefoot on my treadmill. I ran 1.5 miles and regretted it later.
Here is an awesome photo that one of my friends took. The photo was taken by Marm O. Set and my friend Devon is the one in the photo. Here is her complete collection of the Vibram Five Finger shoes. Brilliant photo!
