If you go this route (which I also recommend), make sure you adjust your striking appropriately, you'll want to land mostly on the balls of your feet or your toes. Landing heel first in zero drop shoes will give you shin splints like you wouldn't believe.

I got some zero drop shoes some time ago. I've been running with a forefoot strike ever since, but with those shoes the muscles on the back of my legs start to hurt consistently about 25 minutes into the run. If I continue, the damage could take up to 2 weeks to repair before I can run again.

I still run with the zero drop shoes small distances from time to time, but it doesn't look like I'll ever be able to get the the point where I can run as fast and/or as long as with regular running shoes. Granted, I'm a relatively fast runner (usually 9km in 45min) and it may work better for lighter running.

Also, be aware that the muscles you use when running that way are very different (much more calf muscle involvement) and you need to build up to it gradually. I was told once to start off running 15% of the distance you did when heel-striking and build up gradually. Also, speaking from my personal experience, if you start to feel a calf muscle tighten up, stop IMMEDIATELY and stretch it. This may be helpful: http://www.barefootrunning.fas.harvard.edu/
