Knees'n'Ankles

A recent topic on weight got me contemplating body mass index and all that bollocks...
My problem is that after long or unduly rough or 'crazy' walks I have suffered sore knees and ankles.
A couple of things I feel may be contributing to this is;
a) new boots - Scarpa Trek Pro's - stiff but pretty tough, the old Garmont's 'felt' better
b) fatigue to said joints through age and/or bodily abuse
So..........without going into too much detail as people are very different in many ways(physically)
What do you do to keep these essential regions healthy - I'm interested in any form of medicine herbal or traditional.
What has worked for you, what have you heard works, and why?
P.S. I am 36 - 5'10" - 80kg, have worked and played hard all my life
Cheers, sbs
