Don’t be surprised to see your doctor in some crazy shoes. 
As I strive to run faster and improve my foot strength, I’ve tried to run and walk in shoes with less and less support. This has included wearing “toe shoes” or Vibram Five Fingers while running or even running barefoot when the weather cooperates. Since Vibram recently came out with a model that might be tolerated in the work environment, I’m giving them a shot. I’m already getting comments from families, but overall the kids love them. I’ll let you know if wearing these on a daily basis turns out just to be a fashion statement or if they indeed make my feet stronger.
