My PowerBook G4's feet are all intact.
Some suggestions:
1) Try different brand of stick on feet. Brand matters.
2) You can try this http://www.welovemacs.com/0761063.html or http://www.welovemacs.com/mrc0062.html (Okay, I know they are not cheap)
To clean off sticky residue, I usually use WD40 or ISO PRO. Spray on a kitchen paper then rub on the affected area off.
