You can get pads for area rugs. I have a thin waffle pad under the one in my living room.
In our bedroom, we have wall to wall carpet. I hate it because it is so filthy in the high traffic areas - which is why I suggest area rugs. My DH doesn't know it yet, but we are replacing that next year!
Comfy shoes are a great idea! I'm in shoes almost all the time because of inherited neuropathy and pain; they help with balance as well. The shoes protect my feet from injury and infection. So far, I still have all my toes...
