I ran a marathon in my VFFs and I've bene running for a year. I was hurting afterwards but definitely survived. In fact, the VFFs allowed me to start running again. Before them, I would run 1-2 miles and have massive knee pain and shin splints. VFFs are awesome, but take your time, get used to them and stretch a lot. They're worth it.
