tutu - Welcome! What I would recommend is return to the ball toe form of running and go run barefoot in a field for a little while, see how you feel. Do that a few times a week and see if the pain returns. http://www.barefootrunners.org/build2/ I would not recommend running heeltoe in vibrams :p I've run in classics and Bikilas I definately prefer the bikilas FWIW
rootz - Welcome!
