The bike-riding does seem to be a good help... I'll have to go to a fitness center for that as there may be snow here by time I have the boot off!

The limp will go in time. I find people make remarks quite often, use my boot as a conversation starter.
"what did you kick?" ...
"hope the other guy isn't hurt as bad"
and the other day this I looked up to see a man limping towards me and he says "Really, I'm not making fun of you" then I turn my head to see him continue on with a normal gait, no limp! Well, whatever, if it makes people more social then I don't care.
