Well, not quite, but the Vibram FiveFingers are shoes that mold to your feet and reproduce the whole experience of bare foot running. At ‘A Passion for Running’ Mark blogs:

Wow. I’m beyond impressed. I’m even considering not starting barefoot running again and running in the fivefingers instead.

See, the unfortunate thing for me here in Canada is that our long cold winter makes barefoot running pretty much impossible for about six months of the year and that means during those six months I lose all the conditioning (i.e. toughening up) on the soles of my feet and I have to start all over again in the spring. (holy runon sentence Batman!).

Enter the vibram fivefingers. Oh. My. God. Today was wonderful. The shoe is so close to barefoot running. I get 90% of the sensation of barefooting with virtually no pain or discomfort when stepping on rocks and twigs and stuff.

Why run barefoot? Some data seems to exist that running the way nature intended ends up damaging you less:

Running in shoes appears to increase the risk of plantar fasciitis and other chronic injuries of the lower limb by modifying the transfer of shock to muscles and supporting structures.
