Okay, all you barefooters I need advice please.
Firstly, let me say, I am no barefoot guru. I attended one weekend about 5 years ago. I took away the concave sole, shape and balance stuff (not that I'm good at it but getting better I think).
What I have a real problem with is - How do you get that rim around the outside?
I always seem to end up with it level with the sole where they meet.
