I know how you feel, not being able to walk like you did. Every day I watch my friend I used to 'walk and talk' with go walking with someone else. As a consequence, I have gained weight, and miss the camraderie. And you're right, no one seems to be able to understand just how much pain this is. Everyone has had 'sore' feet at one time or another, and probably uses that as their frame of reference. Everyone at this board understands, though.
