I got a pair of Vibrams for my fiance (Bikila) and I (Speed) and it is the only shoe we run in. If you are not used to any barefoot walking or running you do need to take it easy at first. But I definitely recommend buying these shoes. I bought her "born to run" and we will defintely be purchasing some Luna sandles. @Dangle I saw that photo on the 5finger FB page you famous!
