Thanks Martian ... my left foot didn't ache at all - just the right. But I guess its possible each foot is different so I can't base it on how my left foot felt. I guess I'll ride on it for a while and see if it feels better. I did notice that when I was riding my knees feel different - tension where there wasn't any before - but I did feel increased strength.
All part of getting used to it, I guess.
Man - just a huge thanks to everyone. You all gave me the little bit of confidence I needed to at least get back on. Now just one ride at a time and hope that my confidence grows!
