The physical therapist is a wonderful man....
He has helped my feet more than anything - he crushed up all of the scar tissue at the base of my foot where my toes connect and it was such a relief. I have numb toes when I ride too, from a previous injury. I know that scar tissue can rebuild itself and does tend to do so, so every once in awhile I plan to go back in and get "crunched" again.
Also, for footbeds, another TE'er suggested footbeds from itsyoursole.com that you warm in the oven and they custom form to your feet. I LOVE them. I had been using some specifically designed for cycling from superfeet.com but these trump them by far.
Good Luck
