I've been chomping at the bit to go running and as if to tease me, the universe sends my Vibrams to my doorstep today! I guess I'll have to be patient and just wear them to walk around for now.
I was just trying some Vibrams on at the store today for possible trail running. Tried the KSO's and the Flows on, I think I liked the KSO's alittle better. I'm not sure what to make of them so far, having the fabric between each toe is very very different to me.
Good luck with the back.
I'm still going to the othopedic guy next week since this seems to be happening more frequently, but for once I'm hoping a doctor will tell me it's all in my head.
