I ran in my Vibrams today. I ran one mile out, walked about 1/2 mile back and ran the rest of the way in. I felt great, but I wanted to take this first time run a little on the easy side. It really felt wonderful. It felt smoother and so free! Very natural. My legs seemed weightless. The bottoms are pretty thick rubber so I didn't feel too much through them as I ran.
The down side is my baby toe on the right foot is hurting a little. It doesn't seem to fit in the spot for it very well. When I was looking into these shoes, I read a few times about this happening. All of the people who had this problem said it worked itself out over time. All my other toes fit fine. I did pull the back lace too tightly at first too. I had to loosen that up so I don't know if that had any bearing on my toe hurting. Maybe it was too tight?
All in all, I think I'm going to like these shoes. I plan on running very short distances in them maybe twice a week and do the 5K beach runs in them. Anything more than that and I'll be wearing my Asics. I don't need an injury 3 weeks before I start the half marathon training. And Jim advised me to be careful with these Vibrams. Since I have not had any bad advice from him yet, I'll keep listening!
